SEO Glossary

Are you starting to educate yourself about Search Engine Optimization (SEO) or Search Engine Optimisation as it’s spelled in different regions and you’re not sure about what all the jargon and acronyms mean?

Here is a sure-fire guide to the most commonly used Search Engine and SEO terms and their meanings.  SEO is a vast and complicated field but the best place to start your understanding is by first learning what the top industry terms mean and how they are relevant to you and your website.

301 status code
A 301 status code or a 301 redirect is referring to a URL redirection and has been permanently moved. This often happens when a new domain name has been acquired for a site or if two web pages are now merged as one. A 301 status code is seen as the most search engine friendly redirection available in today’s SEO world.

302 status code
A 302 status code is another way of URL redirection but unlike a 301 redirect, a 302 is only a temporary redirect and is often seen as spammy. There is little reason to use a 302 redirect and you must be aware that many search engines automatically see a 302 redirect as spam.

404 status code
A 404 status code is a standard HTTP response code indicating that a page cannot be found or it’s a ‘dead link’. There can be several reasons for this code to appear. The most common are that the page has been moved, the user typed in the wrong URL or it is simply a dead link. It is also quite common to create a custom 404 error page on each website that allows the user to navigate to the correct page either by listing a sitemap or giving the option to search within the domain for the correct page.

A Search Engine algorithm is a set of rules or formula created by each individual Search Engine to determine relevance and value of each web page. The algorithms are in constant update to ensure that the most relevant web pages are being displayed for each search query. While the exact formula for each Search Engines algorithm is safely guarded, there are a few factors that websites can consistenly expect the algorithms to test; accuracy, relevance, importance and popularity.

Alt tags
An image alt tag or HTML alternative text tag is the text used to describe an image within a website. These tags are used for both the visually impaired as well as serves as a way for the Search Engines to “read” your image. The proper use of this tag is important and should use relevant keywords to accurately describe each image on your website.

Anchor text
An anchor text refers to the clickable (hyperlinked) portion of text within a webpage. The words used as the anchor text are generally a relevant keyword phrase to whatever page they are being linked to. Anchor text has also become a valid technique for inbound marketing in an effort to raise the relevance of a webpage for a certain keyword phrase. Anchor texts are also used internally within a website to help a user navigate from one page to the next with ease.

Auto-generated pages
Auto generated pages are created using a script or computer program to generate thousands of irrelavent and keyword stuffed pages that have no value to the human reader. These auto generated pages are often used as a Black Hat SEO tactic to quickly increase a client’s web traffic by using the auto generated page as a doorway which is then redirected to the actual website. Using a tactic such as this can result in heavy penalties from the search engines and can often leave you blacklisted from the Search Engines.

Backlinks (or Back Links)
Backlinks, or inbound links, are incoming links from other websites who have mentioned your company or used your company as a source of authority. Building a strong link profile consists of obtaining inbound links from credible and relevant sources who will boost your quality score and/or PageRank. Backlinking is often referred to as the ‘backbone of SEO’ as each backlink serves as a ‘vote’ for your site and, in turn, works to increase your sites visibility on the SERPs.

Bad link neighbourhood
This is a group of non-related sites all linked together in an attempt to strengthen a website’s link profile or build PageRank. The links often include pharmacy, porn sites, casinos, and so on. These are often created with link farms or low quality directories and can easily and quickly get your site penalised or blacklisted.

Bing is the self advertised ‘decision engine’ powered by Microsoft and serves as Google’s closest competitor in the Search Engine world. Launching in June 2009, Bing has continued to promise to deliver the most relevant search results to it’s users. While it’s still lagging in many parts of the world, it has increasinly gained in popularity in the U.S. with its ‘Bing It On Challenge.’ Also in 2009, Bing struck a 10 year deal with Yahoo! to power all of it’s search engines and search partners which is why you often see very similar results from the two search engines.

Black hat SEO
Black Hat SEO is the use of unethical web tactics to improve a website’s presence on the Search Engines. While many of these tactics are simply ‘old school’ SEO practices, they have long since been banned for ethical reasons as it’s seen as ‘cheating.’ While many black hat tactics may give you an initial boost in rankings, penalties will very soon follow and could even cause your domain to become blacklisted by the Search Engines. Black Hat tactics can be done both on-site and off and you should make sure that you understand the ins and outs of any SEO program being implemented for your website.

A company blog is an important part of an SEO strategy. As well as being able to add fresh, updated copy to a website, you can create blog articles that target relevant keywords for your website. A blog also allows a company to have an interactive forum with their consumers, something that can’t be duplicated on a static web page. Blogs have also become increasingly popular as social networks serve as an easy avenue for blog articles to be shared and discussed.

Bounce rate
“A bounce rate is the percentage at which people exit a website after only viewing one page. This, in terms, means that the landing page through which a person entered the site was not what the person was searching for and therefore ‘bounced’ off the page. This metric is used to measure visit quality – a high bounce rate
generally indicates that site entrance pages aren’t relevant to your visitors. While there are several indications that could result in an increased bounce rate, it is generally important to have as low of a bounce rate as possible.”

In SEO terms, this refers to the way Search Engines “memorise” or “take a picture” of web pages, allowing you to quickly navigate to the cached version of a page. If a webpage is in your cache then the next time you go to open the page, you are actually opening it from your computer’s last memory of you visiting that page. This help saves time and can save your time when opening a page. Having said that, it is also importantly to frequently empty your cache so as to not overwhelm your computer.

Call to action
A call-to-action is the copy or text on a web page or advertisment that encourages the user to complete an action. Anything from asking a user to sign up for your newsletter to asking them to give you a call is considered a call-to-action. This is, arguably, the most critical point of advertising because it is the point that will determine if a user leaves your page or converts into a customer. Each action is determined by the individual website and can come in many different forms depending on the overall goals of the webmaster.

Citations or directory listings are defined as “mentions” of your business name and address on other webpages. The goal of citations are to let the Search Engines know that your site is out there and to increase the number of inbound links pointing back to your site. While the importance of citations/directory listings have decreased over time, they are still an important part of your over-all SEO process and can serve as valuable links and ‘votes’ for your website.
