A keyword, a single term, in information extraction, is an expression used in information retrieval. Keywords make up a specialized vocabulary for usage in electronic resources. It can be a word or phrase, but more commonly it is an acronym. The use of keywords in keyword search tools is most common in the field of web searching and in keyword based queries such as Yahoo!
A keyword is a short term keyword or phrase used to optimize content. Using keyword optimization tools and techniques, a site can be found by optimizing for a keyword. Long Tail keywords are those that are very specific in content or are nearly so. Long tail keywords are not necessarily easy to come up with in keyword databases. Most of them are too general.
A topical long-tail keyword is a keyword that is searched on a monthly basis in Google. This keyword is the product or service which most people would use daily. So, it can be used as a target keyword or as a synonym for popular way to find products on a daily basis. Searching for this keyword monthly brings up billions of potential matches and this makes it a popular way to find most products. A topical long-tail keyword in a website’s meta tag or title tag can bring thousands of websites to a site’s index.
Some common keywords used by web search engines are also called “keywords with special meaning”. Some examples of keywords with special meaning are movies, television shows, actors, actresses, music artists, brands and product names. These keywords can have a great number of variations depending on how they are used.
Some SEO experts also suggest the use of keywords having large volume of searches over a short period of time. Examples of these are the top searches on Google, Yahoo, Ask, AOL and Wikipedia. By using these kinds of keywords, the chances of your site appearing high on search engine results pages increase.
Keyword analytics is another useful tool that you can use to check the efficiency of your SEO marketing campaign. It takes the guesswork out of keyword optimization by tracking the number of times a given keyword appears on different pages of your website. This gives you an idea if your keywords are effective or not. You can use the data to check which of your keywords are bringing you traffic, analyze the competition’s page rankings and monitor keyword popularity on major search engines like Google and Bing.
