September and early October was one crazy month for SEOs and Webmasters as it related to Google search.
It started with our report on the Google EMD update and continued when we learned about an algorithm update to Panda. We also had an image update and then a confirmed Penguin refresh - so it has been a pretty busy end of September and early October.
Here is a chart to show the recent changes & updates:

Of course, I cannot forget to mention Google celebrated their 14th birthday this past month.

I meant "is that seroundtable.com's graph?" It was a question not a statement. Although I worded it bad I admit!

Hello Barry, Sorry for trouble. I think you have a misunderstanding here. When for the first time I replied to this post, it did not publish. So I thought It might have been caught by spam filter, as I had posted a link reference to your own article giving information about recent page layout algorithm which you did not include in this particular post. I do apologize, if my information is incorrect. Thanks for replying.

its mean that if any person is optimizing and having 30 keywords for per website so will they have to purchase 30 domains ? i think this is not good.
