Keyword phrase – This refers to a search phrase that comprises a number of keywords.
Keywords – Specific words that facilitate the identification of relevant web page(s) by the search engine are known as Keywords. In the absence of relevant keywords, the web page will not show up in any search result. So keywords have a significant role to play in driving traffic to a website.
Keyword Density – Since keywords drive traffic leading to enhanced revenue, it is judicious to incorporate a large number of relevant keywords on your web page because when more number of given keywords appear on a web page, the search engine gives more weight to it. A large number of keywords is referred to as Keyword Density.
Keyword Matching– When a user inserts a search query, matching advertising or information is provided by the search engine. The process of selecting this information is based on linking similar keywords; hence the term Keyword Matching which includes four kinds of matches:
Broad Match
Exact Match
Phrase Match
Negative Keyword
Keyword Popularity – If a particular keyword is searched very often by Internet users, it indicates the popularity of that keyword. Keyword popularity numbers may accessed through WordTracker.com and/or Overture's Keyword Selector Tool (http://inventory.overture.com).
Keyword Prominence – the HTML source code of a web page contains certain words; if those words are placed high up in the page, the search engine will give it more weight. As a result, the first paragraph of a page is always full of important keywords and marketing spiel has to take a back stand. In this context, it is advisable to start your title tags with a good keyword rather than the conventional "Welcome to" that is meaningless.
Keyword proximity – Search engines identify and rank pages based on closeness between two or more keywords; the closer the better. Closeness indicates that no other word comes between the keywords; for instance, How to source Energy from Solar Power is not as good in proximity of keywords as: How to source Solar Power Energy.
Keyword Research – Since keywords play such an important role in e-commerce, research has been conducted to compile words that are most frequently used by netizens as a search query. This list is also useful when developing relevant web page content.
Keyword Stuffing – This is a dubious method of lifting the page ranking by introducing large number of keywords into the copy and the HTML. This stuffing is done by making the text the same color as the background, hiding keywords in comment tags, overfilling alt tags with long strings of keywords, etc.
