Way fewer blogs are ranking well in the SERPs, and probably not even getting indexed. Google Alerts are reporting a lot fewer blogs, too.
What's up and ranking better are way more ecommerce or sales links in ther SERPs. Google Alerts showing lots more of these pages getting indexed. It looks like you can throw up an ecommerce site for a product listing and get it indexed. I know, many of you will have a different view. I'm just observing the SERPs I'm seeing.
