The keyword density (KD) is the percentage of the needed weight of a keyword on a web page. The formula to get the overall keyword density of a specific keyword is by getting the total number of frequency where keyword appeared and then divide it by the total number of words on the page. One good example is when your keyword appears only once in a page that contains 100 words, the overall keyword density is 1%. Search Engine has a maximum word density for not to consider your site as spam and mostly, it around 10 percent for a two-word phrase. For all we know, they have their own formula to detect the kind of spam. So, don´t ever try to exceed or over optimized your keyword density for a particular page. If ever this will happen, it will take weeks or months to get back on search result. For proper keyword placement, they can be placed in title, Meta tags, heading, link text, body text, alt image text, link url’s and comments.

Keyword prominence is one of the factors that we should know in placing the targeted keywords for our website. It defined how close to start of the web page that our keyword appeared. In a simple term, if our keyword appeared closer to the top of our page, it said to be more relevant to the search engine results that provided for the users. Keyword prominence can be applied by altering the web page area such as; the heading, the page content, the alt text, the title and the description. It can understand through generated percentage according to positioning of the targeted keyword in a web page. Majority of search engines (Google, Yahoo and MSN) have their own way of knowing a good prominence in a web page. For those reasons, I recommend you to use 85% to 90% of prominence just to meet all the ideal percentages of the three major search engines.

Search Engines (SE´s) are now relying on the science of information retrieval (IR) and the two critical components for the functionality. First, relevance in which the degree of the documents is being returned by the search engine, depending on the purpose and terms that matched the user´s query. Second, is the popularity when relative importance is being measure by reference of a given document that matches the terms or phrase of the search user´s. The two decisive components have been translated to web search in the form of document analysis and link analysis. In document analysis, SE looks at in the form of essential HTML ( Meta tags, heading, alt text and body) and the quality itself. While, in link analysis is not only measure the quality of link but also consider what they say about that page or site.
