As promised last month, we're going to report monthly on Google SERP changes. This month, the following observations on WebmasterWorld have been made:
- Some optimized sites that are being changed for better relevance are just not performing as well. Their rankings seem to be doing worse.
- "Boring websites" with no linkbait are vulnerable to ranking shifts.
- Bigger sites do better. ("Size does matter.")
- Some datacenters have shown changes, but they reverted to their original rankings. Forum members suspect it's part of a new data push (or experimentation, at least).
Forum discussion continues at WebmasterWorld.

Thanks for the monthly Webmaster Monthly Google SERP Change Reports. It's nice to have a resource like this to turn to when your too busy with client SEO.

How is bigger better or where is the evidence of this?

Good question Jaan. Those should be addressed in the forum. All we did with this post was summarize what people are saying.

Hate to add a "me too", but as Jeff said, it is very refreshing to see a summary like this. Thanks Barry; well appreciated. Dan
