SEO Defined: 10 Basic Definitions You Need to Know

There are a number of words and acronyms involved in search engine optimization (SEO) which are not considered self-explanatory. It is helpful to know what they mean before reading articles or forum messages about SEO. Read on to learn about some of their definitions…

Keyword Density: Webpages are more likely to receive a high ranking in search results for a particular keyword if they use that word frequently (but not excessively). The keyword density is the percentage of the total number of words in which one keyword is used.

META Tags: This refers to part of a website’s HTML code, near the beginning, and includes the Title, Description, and Keywords tags. The Title tag is visible to both users and search engines, while the Description and Keywords tags are only used by search engine spiders. Many SEO experts feel that the “Keywords” tag is of minimal importance.

PageRank: The PageRank, or “PR”, of a website is a numeric ranking applied to it by Google, and largely based upon how many other sites link to it. The higher the ranking, the closer to the top of relevant search results a website is likely to appear. If you own a website, it is helpful to know its PageRank and check it periodically to determine if progress is being made.

Link Bombing: This practice (sometimes called “Google Bombing”) remains effective to some extent, but generally doesn’t allow for the kind of manipulation it once did. The concept is that if enough websites link to a particular webpage and use a specific phrase in the link text, the targeted site will appear in the top search results for that phrase or keyword.

White/Black Hat: Different types of SEO practices are frequently referred to in this manner. “Black hat” techniques usually are efforts to manipulate search results which are opposed by search engines; on the other hand, “white hat” SEO methods can improve a site’s ranking but generally don’t have the potential to harm it.

CTR: This acronym, meaning Click Through Rate, refers to the percentage of website users who click on a link or advertisement. This term can be applied to search results, e-mail advertisements, banners, and other forms of promotion.

Natural/Organic: When website traffic is called “organic” or “natural”, it means that it comes without the recipient providing payment or anything in exchange. Examples of this are unpaid search listing clicks and voluntary links from other websites or blogs. SEO is a major way to generate such traffic.

Reciprocal Linking: This is a method in which two website owners add links to each other’s sites. It can provide both SEO and direct traffic benefits, especially if the websites are about similar subjects. However, Google has imposed a policy aimed at limiting the SEO benefits of reciprocal linking.

Analytics: When it involves SEO, this is the practice of collecting and analyzing data on a website’s traffic, then using it to more effectively promote the site. It can also be useful when making decisions with regard to web design.

Directories: Online directories are often used as a part of SEO promotional efforts. This usually refers to either “web directories”, which are categorized lists of approved sites (like dmoz.org), or “article directories”, which contain articles on one or more subjects (such as searchwarp.com).
