Comment on WordPress SEO Tutorial by Rand Fishkin.
Just try to remember that there may be times when you do want to search for something and when you don’t find what you are looking for in the first term then you move on to another search related search term to find out what you are looking for?
Ok I know its a bit complex to understand so let me point out an example. If you are searching for some tips on SEO for your blog and you make a query called “seo tips for blogs” and you don’t find what you are looking for and then you move on to another related search term like “best seo tips for blogs” and then again you move on to another search term like “top seo tips for blogs” and then you click on a search result.
So just imagine there are millions of people who are using Google search engine to search for information they need so there might be a significant number of people who might have made a similar query like you in the same pattern so these query patterns are taken into consideration and also Google looks for the page which got the most clicks in this particular search pattern so just imagine your site got more clicks in the above mentioned search pattern then Google will adjust the rankings of this particular index so that users finds out what they are looking for.
