[Goyum]

Let me take a shot at this one..

Well, Google survives on services like Adwords, doubleclick etc. These are services dedicated for companies who can be found easily on the Google search engine.

Now lets say I do various SEO best practices and rank my keyword or website in the first 3 SERP, would I invest in Adwords ever? Now, imagine there are various players for the same doing the same. How would Google survive?

Hence, Google keeps updating its algorithm time and again.

Also, to this, they try to make search results easier and better for any user, hence the frequent update.
