Almost 80% of the web users use search engines to hunt for information on the net. So it can be comfortably said that search engines are the most popular medium to look for information on the web. Therefore, if you want to master keyword research a basic understanding of search engines is a must.
These search engines keep track not only of the words themselves, but also of how frequently they were used to search. The most used terms will naturally be the best keywords to use in a web page dealing with that topic. In the past, search engines used to give website ranking based on the number of times a keyword occurs on your website.
Therefore, the page containing the keyword greatest number of times would rank first on the search. But this was used by many spammers to their advantage. Hence, this practise is changing now. Search engines rank pages in new ways and are devising innovative algorithms.
One such method is semantic indexing. This helps to isolate only the most relevant documents for every search query. Also remember that search engines do not rank pages in isolation. They consider the entire website before ranking any page on the website.
Hence it is very important to categorize your website and define its content appropriately. If all content on your website is related, only then will the search engines give it a significant ranking. This is because search engines take into consideration the entire theme of the website before providing it a rank. Therefore all the keywords you use on your website should be related.
Furthermore, design your website carefully. Do create links within your article body. These links should take your readers to other pages of your website where they can find more information about the topic that you’re discussing. Creating links using anchor texts can actually make your articles more search engine-friendly.
Place your keywords intelligently in the written text on your blog. People generally believe that the more instances of the main keyword there are, the better the chance for the article to be found.
The hitch to this is that search engines will simply ignore articles which are saturated with keywords. The usual tolerated limit is 3-5 percent density. This means that for every two hundred words in the article the keyword occurs 5 times. Most articles will limit themselves from 1 to 1.5 %.
