Google Inside SearchThe tradition of posting all the recent monthly search changes and updates on the first Friday of the month by Google for the sake of transparency, continued this month as well- Google has published a long list of more than 50 search updates for April.

Of course the big update this month was the Penguin update, but there were also many other changes that may have affected pretty significantly the results. Interestingly enough, even though there were two Panda updates on April (3.5 and 3.6) they aren’t mentioned at all.

Here’s a summary of all the main search updates and changes that happened on April:

Index

Apparently, Google made some significant changes to the search index. Even though that the index is constantly growing as Google indexed more and more pages, Google now stating that the index grown in April by 15 percent which seems rather meaningful.
