Search Engine Optimisation and Marketing glossary - jargon, terminology and definitions
Search engine optimization (SEO) and search engine marketing (SEM) are such hot topics nowadays, constantly evolving, that it’s easy to get lost in all the various terminology and jargon used - especially when you’re starting out and trying to learn SEO/SEM strategies.
Even if you don’t intend to handle search engine optimization yourself and contract the work to others, it’s important to understand what your contractors are telling you. With some basic familiarity of SEO terminology, you’ll also be able to tell if a contractor is heading down the wrong path - possibly taking your site with them in the form of a ranking penalty.
The following glossary lists some common SEO/SEM terms and definitions:
301 - A server response code, meaning “page has been permanently moved”. A 301 redirect is commonly used to redirect sites or individual pages in cases where a domain or page name is changed and is usually the preferred method of redirection by search engines.
302 - A server response code meaning “page has temporarily moved”. 302 redirects are a touchy subject with many people involved with SEO as they can be also used against a site through a process called 302 hijacking or pagejacking.
404 - Not Found - The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
Anchor Text - The visible text component of a hyperlink.
Alexa ranking - Alexa is a search engine that provides extra information such as traffic rankings. An Alexa ranking is an indicator used to gauge site performance, based on comparisons drawn against other sites.
Algorithm - A mathematical formula used in calculating search engine ranking. The goal of any SEOP is to understand the algorithm as best as possible. Algorithms of course are very closely guarded secrets and I have never met anyone who has “cracked” an algorithm. Search engine algorithms change regularly to prevent anyone from gaming the system.
ALT Image tag - Search engines aren’t able to read images as such, so the alt tag or text attribute describes what the image represents.
Black hat - A person engaged in or tactic used to increase search engine rankings using methods frowned upon by search engine companies.
Bot - usually used in reference to a search engine robot or spider; software applications that retrieve web page information to feed into a database.
CSS - Cascading Style Sheets. Used mainly to decrease the amount of source code on a page, by referencing a single set of instructions on how to display various elements.
Crawl - the process by which search engine spiders retrieve web page information.
CTR - Click Through Rate. A ratio of views of a page, link or advertisement that result in a click to another page.
DMOZ - Directory MOZilla is a human reviewed directory, the contents of which appear on many sites, including Google. A listing in DMOZ is said to assist boosting rankings in in Google’s general search results.
Doorway Page - a page used for driving traffic to another page and usually focusing on specific keywords. Generally, doorway pages are designed for search engines only, human visitors never see them - consequently, they are frowned upon. Doorway pages should not be confused with landing pages, a legitimate strategy.
Dupe/Duplicate content - usually used in reference to a penalty applied by a search engine for the same content appearing on different pages/sites. In theory, the site/page that was added to the search engine last should be the one that is penalized.
FFA - Free For All pages; basically a link farm. You add your site link to the page, it then gets pushed down as other links are added until your link is ultimately pushed off the page. Not a suggested method of promotion or link building. Read my article on FFA pages.
Flux - A term to describe the shuffling of positions in search engine results in between major updates.

Keyword/Keyphrase - A word or words that strongly relate to a page/site topic or search engine query.
Keyword Stuffing - Where a keyword or phrase is used excessively in page content or alt tags in an attempt to gain higher rankings. Can result in page penalties or bans.
Landing page - A page that is optimized and very targeted towards a particular subject. An effective/valid optimization and sales conversion strategy when implemented correctly.
Link Farm - A page that consists of little else but links to other sites and usually the sites listed have links back to the farm page. The goal of a link farm is to artificially boost rankings through link popularity and is consequently at risk of penalty or ban.
Link popularity - A gauge of a site’s popularity based on the number of inbound links. Link popularity is a factor in search engine ranking and has greater strength (in theory) where inbound links are from other quality sites.
Meta tags - These mainly refer to the title, keywords and description tags. They are basically a summary of the content that is on the page in different formats. Metatag content does play a role in rankings for many search engines.
MSN - A reference to Microsoft’s search engine.
Mirror Site - A copy of a site with some content differences to target particular keywords. Not a recommended strategy as it can trigger a penalty or ban.
