 A

Above the Fold

A term traditionally used to describe the top portion of a newspaper. In email or web marketing it means the area of content viewable prior to scrolling. Some people also define above the fold as an ad location at the very top of the screen, but due to banner blindness typical ad locations do not perform as well as ads that are well integrated into content. If ads look like content they typically perform much better.

See also:

Absolute Link

A link which shows the full URL of the page being linked at. Some links only show relative link paths instead of having the entire reference URL within the a href tag. Due to canonicalization and hijacking related issues it is typically preferred to use absolute links over relative links.

Example absolute link

<a href="http://seobook.com/folder/filename.html">Cool Stuff</a>

Example relative link

<a href="../folder/filename.html">Cool Stuff</a> 

AdCenter

Microsoft's cost per click ad network.

While it has a few cool features (including dayparting and demographic based bidding) it is still quite nascent in nature compared to Google AdWords. Due to Microsoft's limited marketshare and program newness many terms are vastly underpriced and present a great arbitrage opportunity.

AdSense

Google's contextual advertising network. Publishers large and small may automatically publish relevant advertisements near their content and share the profits from those ad clicks with Google.

AdSense offers a highly scalable automated ad revenue stream which will help some publishers establish a baseline for the value of their ad inventory. In many cases AdSense will be underpriced, but that is the trade off for automating ad sales.

AdSense ad auction formats include

  • cost per click - advertisers are only charged when ads are clicked on
  • CPM - advertisers are charged a certain amount per ad impression. Advertisers can target sites based on keyword, category, or demographic information.

AdSense ad formats include

  • text
  • graphic
  • animated graphics
  • videos

In some cases I have seen ads which got a 2 or 3% click through rate (CTR), while sites that are optimized for maximum CTR (through aggressive ad integration) can obtain as high as a 50 or 60% CTR depending on

  • how niche their site is
  • how commercially oriented their site is
  • the relevancy and depth of advertisers in their vertical

It is also worth pointing out that if you are too aggressive in monetizing your site before it has built up adequate authority your site may never gain enough authority to become highly profitable.

Depending on your vertical your most efficient monetization model may be any of the following

  • AdSense
  • affiliate marketing
  • direct ad sales
  • selling your own products and services
  • a mixture of the above

AdWords

Google's advertisement and link auction network. Most of Google's ads are keyword targeted and sold on a cost per click basis in an auction which factors in ad clickthrough rate as well as max bid. Google is looking into expanding their ad network to include video ads, demographic targeting, affiliate ads, radio ads, and traditional print ads.

AdWords is an increasingly complex marketplace. One could write a 300 page book just covering AdWords. Rather than doing that here I thought it would be useful to link to many relevant resources.

See also:

Affiliate Marketing

Affiliate marketing programs allows merchants to expand their market reach and mindshare by paying independent agents on a cost per action (CPA) basis. Affiliates only get paid if visitors complete an action.

Most affiliates make next to nothing because they are not aggressive marketers, have no real focus, fall for wasting money on instant wealth programs that lead them to buying a bunch of unneeded garbage via other's affiliate links, and do not attempt to create any real value.

Some power affiliates make hundreds of thousands or millions of dollars per year because they are heavily focused on automation and/or tap large traffic streams. Typically niche affiliate sites make more per unit effort than overtly broad ones because they are easier to focus (and thus have a higher conversion rate).

Selling a conversion is typically harder than selling a click (like AdSense does, for instance). Search engines are increasingly looking to remove the noise low quality thin affiliate sites ad to the search results through the use of

See also:

Age

Some social networks or search systems may take site age, page age, user account age, and related historical data into account when determining how much to trust that person, website, or document. Some specialty search engines, like blog search engines, may also boost the relevancy of new documents.

Fresh content which is also cited on many other channels (like related blogs) will temporarily rank better than you might expect because many of the other channels which cite the content will cite it off their home page or a well trusted high PageRank page. After those sites publish more content and the reference page falls into their archives those links are typically from pages which do not have as much link authority as their home pages.

Some search engines may also try to classify sites to understand what type of sites they are, as in news sites or reference sites that do not need updated that often. They may also look at individual pages and try to classify them based on how frequently they change.

See also:

AJAX

Asynchronous JavaScript and XML is a technique which allows a web page to request additional data from a server without requiring a new page to load.

Alexa

Amazon.com owned search service which measures website traffic.

Alexa is heavily biased toward sites that focus on marketing and webmaster communities. While not being highly accurate it is free.

See also

AllTheWeb

Search engine which was created by Fast, then bought by Overture, which was bought by Yahoo. Yahoo may use AllTheWeb as a test bed for new search technologies and features.

See also:

Alt Attribute

Blind people and most major search engines are not able to easily distinguish what is in an image. Using an image alt attribute allows you to help screen readers and search engines understand the function of an image by providing a text equivalent for the object.

Example usage

<img src="http://www.seobook.com/images/whammy.gif" height="140" width="120" alt="Press Your Luck Whammy." />

See also

AltaVista

Search engine bought out by Overture prior to Overture being bought by Yahoo. AltaVista was an early powerhouse in search, but on October 25, 1999 they did a major algorithmic update which caused them to dump many websites. Ultimately that update and brand mismanagement drove themselves toward irrelevancy and a loss of mindshare and marketshare.

See also:

Amazon.com

The largest internet retailing website. Amazon.com is rich in consumer generated media. Amazon also owns a number of other popular websites, including IMDB and Alexa.

See also:

Analytics

Software which allows you to track your page views, user paths, and conversion statistics based upon interpreting your log files or through including a JavaScript tracking code on your site.

Ad networks are a game of margins. Marketers who track user action will have a distinct advantage over those who do not.

See also:

Anchor Text

The text that a user would click on to follow a link. In the case the link is an image the image alt attribute may act in the place of anchor text.

Search engines assume that your page is authoritative for the words that people include in links pointing at your site. When links occur naturally they typically have a wide array of anchor text combinations. Too much similar anchor text may be a considered a sign of manipulation, and thus discounted or filtered. Make sure when you are building links that you control that you try to mix up your anchor text.

Example of anchor text:

<a href="http://www.seobook.com/">Search Engine Optimization Blog</a>

Outside of your core brand terms if you are targeting Google you probably do not want any more than 10% to 20% of your anchor text to be the same. You can use Backlink Analyzer to compare the anchor text profile of other top ranked competing sites.

AOL

Popular web portal which merged with Time Warner.

API

Application Program Interface - a series of conventions or routines used to access software functions. Most major search products have an API program.

Arbitrage

Exploiting market inefficiencies by buying and reselling a commodity for a profit. As it relates to the search market, many thin content sites laced with an Overture feed or AdSense ads buy traffic from the major search engines and hope to send some percent of that traffic clicking out on a higher priced ad. Shopping search engines generally draw most of their traffic through arbitrage.

See also:

ASP

Active Server Pages - a dynamic Microsoft programming language.

See also:

Ask

Ask is a search engine owned by InterActive Corp. They were originally named Ask Jeeves, but they dumped Jeeves in early 2006. Their search engine is powered by the Teoma search technology, which is largely reliant upon Kleinberg's concept of hubs and authorities.

See also:

Authority

The ability of a page or domain to rank well in search engines. Five large factors associated with site and page authority are link equity, site age, traffic trends, site history, and publishing unique original quality content.

Search engines constantly tweak their algorithms to try to balance relevancy algorithms based on topical authority and overall authority across the entire web. Sites may be considered topical authorities or general authorities. For example, Wikipedia and DMOZ are considered broad general authority sites. This site is a topical authority on SEO, but not a broad general authority.

Authorities

Topical authorities are sites which are well trusted and well cited by experts within their topical community. A topical authority is a page which is referenced from many topical experts and hub sites. A topical hub is page which references many authorities.

Example potential topical authorities:

  • the largest brands in your field
  • the top blogger talking about your subject
  • the Wikipedia or DMOZ page about your topic

Automated Bid Management Software

Pay per click search engines are growing increasingly complex in their offerings. To help large advertisers cope with the increasing sophistication and complexity of these offerings some search engines and third party software developers have created software which makes it easier to control your ad spend. Some of the more advanced tools can integrate with your analytics programs and help you focus on conversion, ROI, and earnings elasticity instead of just looking at cost per click.

If you want to program internal bid management software you can get a developer token to use the Google AdWords API.

Bait and Switch

Marketing technique where you make something look overtly pure or as though it has another purpose to get people to believe in it or vote for it (by linking at it or sharing it with friends), then switch the intent or purpose of the website after you gain authority.

It is generally easier to get links to informational websites than commercial sites. Some new sites might gain authority much quicker if they tried looking noncommercial and gaining influence before trying to monetize their market position.

During the first web boom many businesses were based on eyeballs more than actually building real value. Many ads were typically quite irrelevant and web users learned to ignore the most common ad types.

In many ways text ads are successful because they are more relevant and look more like content, but with the recent surge in the popularity of text ads some have speculated that in time people may eventually become text ad blind as well.

Nick Denton stated:

Imagine a web in which Google and Overture text ads are everywhere . Not only beside search results, but next to every article and weblog post. Ubiquity breeds contempt. Text ads, coupled with content targeting, are more effective than graphic ads for many advertisers; but they too, like banners, will suffer reader burnout.

Battelle, John

Popular search and media blogger who co-founded The Industry Standard and Wired, and authored a popular book on search called The Search.

See also:

Behavioral Targeting

Ad targeting based on past recent experience and/or implied intent. For example, if I recently searched for mortgages then am later reading a book review the page may still show me mortgage ads.

Bias

A prejudice based on experiences or a particular worldview.

Any media channel, publishing format, organization, or person is biased by

  • how and why they were created and their own experiences
  • the current set of social standards in which they exist
  • other markets they operate in
  • the need for self preservation
  • how they interface with the world around them
  • their capital, knowledge, status, or technological advantages and limitations

Search engines aim to be relevant to users, but they also need to be profitable. Since search engines sell commercial ads some of the largest search engines may bias their organic search results toward informational (ie: non-commercial) websites. Some search engines are also biased toward information which has been published online for a great deal of time and is heavily cited.

Search personalization biases our search results based on our own media consumption and searching habits.

Large news organizations tend to aim for widely acceptable neutrality rather than objectivity. Some of the most popular individual web authors / publishers tend to be quite biased in nature. Rather than bias hurting one's exposure

  • The known / learned bias of a specific author may make their news more appealing than news from an organization that aimed to seem arbitrarily neutral.
  • I believe biased channels most likely typically have a larger readership than unbiased channels.
  • Most people prefer to subscribe to media which matches their own biases worldview.
  • If more people read what you write and passionately agree with it then they are more likely to link at it.
  • Things which are biased in nature are typically easier to be cited than things which are unbiased.

Black Hat SEO

Search engines set up guidelines that help them extract billions of dollars of ad revenue from the work of publishers and the attention of searchers. Within that highly profitable framework search engines consider certain marketing techniques deceptive in nature, and label them as black hat SEO. Those which are considered within their guidelines are called white hat SEO techniques. The search guidelines are not a static set of rules, and things that may be considered legitimate one day may be considered deceptive the next.

Search engines are not without flaws in their business models, but there is nothing immoral or illegal about testing search algorithms to understand how search engines work.

People who have extensively tested search algorithms are probably more competent and more knowledgeable search marketers than those who give themselves the arbitrary label of white hat SEOs while calling others black hat SEOs.

When making large investments in processes that are not entirely clear trust is important. Rather than looking for reasons to not work with an SEO it is best to look for signs of trust in a person you would like to work with.

Block Level Analysis

A method used to break a page down into multiple points on the web graph by breaking its pages down into smaller blocks.

Block level link analysis can be used to help determine if content is page specific or part of a navigational system. It also can help determine if a link is a natural editorial link, what other links that link should be associated with, and/or if it is an advertisement. Search engines generally do not want to count advertisements as votes.

Blog

A periodically updated journal, typically formatted in reverse chronological order. Many blogs not only archive and categorize information, but also provide a feed and allow simple user interaction like leaving comments on the posts.

Most blogs tend to be personal in nature. Blogs are generally quite authoritative with heavy link equity because they give people a reason to frequently come back to their site, read their content, and link to whatever they think is interesting.

The most popular blogging platforms are Wordpress, Blogger, Movable Type, and Typepad.

Blog Comment Spam

Either manually or automatically (via a software program) adding low value or no value comments to other sites.

Automated blog spam:

Nice post!

Manual blog spam:

I just wrote about this on my site. I don't know you, but I thought I would add no value to your site other than linking through to mine. Check it out!!!!!
by
cluebag manual spammer (usually with keywords as my name)

As time passes both manual and automated blog comment spam systems are evolving to look more like legitimate comments. I have seen some automated blog comment spam systems that have multiple fake personas that converse with one another.

Blogger

Blogger is a free blog platform owned by Google.

It allows you to publish sites on a subdomain off of Blogspot.com, or to FTP content to your own domain. If you are serious about building a brand or making money online you should publish your content to your own domain because it can be hard to reclaim a website's link equity and age related trust if you have built years of link equity into a subdomain on someone else's website.

Blogger is probably the easiest blogging software tool to use, but it lacks many some features present in other blog platforms.

See also:

Blogroll

Link list on a blog, usually linking to other blogs owned by the same company or friends of that blogger.

Bold

A way to make words appear in a bolder font. Words that appear in a bolder font are more likely to be read by humans that are scanning a page. A search engine may also place slightly greater weighting on these words than regular text, but if you write natural page copy and a word or phrase appears on a page many times it probably does not make sense or look natural if you bold ever occurrence.

Example use:

  • <b>words</b>
  • <strong>words</strong>

Either would appear as words.

Bookmarks

Most browsers come with the ability to bookmark your favorite pages. Many web based services have also been created to allow you to bookmark and share your favorite resources. The popularity of a document (as measured in terms of link equity, number of bookmarks, or usage data) is a signal for the quality of the information. Some search engines may eventually use bookmarks to help aid their search relevancy.

Social bookmarking sites are often called tagging sites. Del.icio.us is the most popular social bookmarking site. Yahoo! MyWeb also allows you to tag results. Google allows you to share feeds and / or tag pages. They also have a program called Google Notebook which allows you to write mini guides of related links and information.

There are also a couple meta news sites that allow you to tag interesting pages. If enough people vote for your story then your story gets featured on the homepage. Slashdot is a tech news site primarily driven by central editors. Digg created a site covering the same type of news, but is a bottoms up news site which allows readers to vote for what they think is interesting. Netscape cloned the Digg business model and content model. Sites like Digg and Netscape are easy sources of links if you can create content that would appeal to those audiences.

Many forms of vertical search, like Google Video or YouTube, allow you to tag content.

See also:

Boolean Search

Many search engines allow you to perform searches that contain mathematical formulas such as AND, OR, or NOT. By default most search engines include AND with your query, requiring results to be relevant for all the words in your query.

Examples:

  • A Google search for SEO Book will return results for SEO AND Book.
  • A Google search for "SEO Book" will return results for the phrase SEO Book.
  • A Google search for SEO Book -Jorge will return results containing SEO AND Book but NOT Jorge.
  • A Google search for ~SEO -SEO will find results with words related to SEO that do not contain SEO.

Some search engines also allow you to search for other unique patterns or filtering ideas. Examples:

Brand

The emotional response associated with your company and/or products.

A brand is built through controlling customer expectations and the social interactions between customers. Building a brand is what allows you to move away from commodity based pricing and move toward higher margin value based pricing.

See also:

Branded Keywords

Keywords or keyword phrases associated with a brand. Typically branded keywords occur late in the buying cycle, and are some of the highest value and highest converting keywords.

Some affiliate marketing programs prevent affiliates from bidding on the core brand related keywords, while others actively encourage it. Either way can work depending on your business model and marketing savvy, but it is important to ensure there is synergy between internal marketing and affiliate marketing programs.

Breadcrumb Navigation

Navigational technique used to help search engines and website users understand the relationship between pages.

Example breadcrumb navigation:

Home > SEO Tools > SEO for Firefox

Whatever page the user is on is unlinked, but the pages above it within the site structure are linked to, and organized starting with the home page, right on down through the site structure.

Brin, Sergey

Co-founder of Google.

Broken Link

A hyperlink which is not functioning. A link which does not lead to the desired location.

Links may broken for a number of reason, but four of the most common reasons are

  • a website going offline
  • linking to content which is temporary in nature (due to licensing structures or other reasons)
  • moving a page's location
  • changing a domain's content management system

Most large websites have some broken links, but if too many of a site's links are broken it may be an indication of outdated content, and it may provide website users with a poor user experience. Both of which may cause search engines to rank a page as being less relevant.

Xenu Link Sleuth is a free software program which crawls websites to find broken links.

Browser

Client used to view the world wide web.

The most popular browsers are Microsoft's Internet Explorer, Mozilla's Firefox, Safari, and Opera.

Bush, Vannevar

WWII scientist who wrote a seminal research paper on the concepts of hypertext and a memory extension device titled As We May Think.

Business.com

A well trusted directory of business websites and information. Business.com is also a large pay per click arbitrage player.

Buying Cycle

Before making large purchases consumers typically research what brands and products fit their needs and wants. Keyword based search marketing allows you to reach consumers at any point in the buying cycle. In many markets branded keywords tend to have high search volumes and high conversion rates.

The buying cycle may consist of the following stages

  • Problem Discovery: prospect discovers a need or want.
  • Search: after discovering a problem look for ways to solve the need or want. These searches may contain words which revolve around the core problem the prospect is trying to solve or words associated with their identity.
  • Evaluate: may do comparison searches to compare different models, and also search for negative information like product sucks, etc.
  • Decide: look for information which reinforces your view of product or service you decided upon
  • Purchase: may search for shipping related information or other price related searches. purchases may also occur offline
  • Reevaluate: some people leave feedback on their purchases . If a person is enthusiastic about your brand they may cut your marketing costs by providing free highly trusted word of mouth marketing.

 C

Cache

Copy of a web page stored by a search engine. When you search the web you are not actively searching the whole web, but are searching files in the search engine index.

Some search engines provide links to cached versions of pages in their search results, and allow you to strip some of the formatting from cached copies of pages.

Calacanis, Jason

Founder of Weblogs, Inc. Also pushed AOL to turn Netscape into a Digg clone.

Canonical URL

Many content management systems are configured with errors which cause duplicate or exceptionally similar content to get indexed under multiple URLs. Many webmasters use inconsistent link structures throughout their site that cause the exact same content to get indexed under multiple URLs. The canonical version of any URL is the single most authoritative version indexed by major search engines. Search engines typically use PageRank or a similar measure to determine which version of a URL is the canonical URL.

Webmasters should use consistent linking structures throughout their sites to ensure that they funnel the maximum amount of PageRank at the URLs they want indexed. When linking to the root level of a site or a folder index it is best to end the link location at a / instead of placing the index.html or default.asp filename in the URL.

Examples of URLs which may contain the same information in spite of being at different web addresses:

  • http://www.seobook.com/
  • http://www.seobook.com/index.shtml
  • http://seobook.com/
  • http://seobook.com/index.shtml
  • http://www.seobook.com/?tracking-code

Catalog (see Index)

Catch All Listing

A listing used by pay per click search engines to monetize long tail terms that are not yet targeted by marketers. This technique may be valuable if you have very competitive key words, but is not ideal since most major search engines have editorial guidelines that prevent bulk untargeted advertising, and most of the places that allow catch all listings have low traffic quality. Catch all listings may be an attractive idea on theme specific search engines and directories though, as they are already pre qualified clicks.

CGI

Common Gateway Interface - interface software between a web server and other machines or software running on that server. Many cgi programs are used to add interactivity to a web site.

Client

A program, computer, or process which makes information requests to another computer, process, or program.

Cloaking

Displaying different content to search engines and searchers. Depending on the intent of the display discrepancy and the strength of the brand of the person / company cloaking it may be considered reasonable or it may get a site banned from a search engine.

Cloaking has many legitimate uses which are within search guidelines. For example, changing user experience based on location is common on many popular websites.

Clustering

In search results the listings from any individual site are typically limited to a certain number and grouped together to make the search results appear neat and organized and to ensure diversity amongst the top ranked results. Clustering can also refer to a technique which allows search engines to group hubs and authorities on a specific topic together to further enhance their value by showing their relationships.

CMS

Content Management System. Tool used to help make it easy to update and add information to a website.

Blog software programs are some of the most popular content management systems currently used on the web. Many content management systems have errors associated with them which make it hard for search engines to index content due to issues such as duplicate content.

Co-citation

In topical authority based search algorithms links which appear near one another on a page may be deemed to be related to one another. In algorithms like latent semantic indexing words which appear near one another often are frequently deemed to be related.

Comments

Many blogs and other content management systems allow readers to leave user feedback.

Leaving enlightening and thoughtful comments on someone else's related website is one way to help get them to notice you.

See also:

  • blog comment spam - the addition of low value or no value comments to other's websites

Comments Tag

Some web developers also place comments in the source code of their work to help make it easy for people to understand the code.

HTML comments in the source code of a document appear as <!-- your comment here -->. They can be viewed if someone types views the source code of a document, but do not appear in the regular formatted HTML rendered version of a document.

In the past some SEOs would stuff keywords in comment tags to help increase the page keyword density, but search has evolved beyond that stage, and at this point using comments to stuff keywords into a page adds to your risk profile and presents little ranking upside potential.

Compacted Information

Information which is generally and widely associated with a product. For example, most published books have an ISBN.

As the number of product databases online increases and duplicate content filters are forced to get more aggressive the keys to getting your information indexed are to have a site with enough authority to be considered the most important document on that topic, or to have enough non compacted information (for example, user reviews) on your product level pages to make them be seen as unique documents.
