If you want to keep your site at the top, you also need to adapt your pages to the latest changes. It is a known fact that all major search engines periodically change their algorithms. That is why different search engines give different search results pages for the same search string.

This opens out a huge scope for businesses and online content publishers to attract people to their website for free.
