Google’s algorithm changes once a day
Did you realise that Google updates its search engine algorithm at least once a day? Aside from the well publicised updates such as Google Caffeine, there are many small updates Google makes that effect the search engine results you’ll see. Keeping up-to-date with all of these changes, making your website compliant and still ranking well can be a challenge, but these changes are necessary for Google to provide relevant results in an ever changing web, and to help their technology keep up-to-date. This video by Google’s Matt Cutts talks about these changes, and the importance of content.
