Are you guys also experiencing fall in traffic to your blogger blog from Google ? Well I am experiencing the same. My blog is about games downloads. Even when I search in google like" download gears of war blogspot" , no blogger blog appears in the search result where as earlier Google was showing blogger blogs in the search results for the similar queries.
Search this in Google: site: your full blog url If you don't see your blog, then you're not indexed, meaning you will not rank for any keywords. Also, it is possible that you are not optimizing for your keywords correctly.
Yes, something is definitely wrong. I have noticed this problem for at least 10 Blogger/Blogspot blogs of my friends. It is strange becuase Google is the owner of Blogger/Blogspot.
Problem is still there. My blog traffic fallen from 2500 to 500 UV within one night. Very terrific. I am worried.
Do you build links for your blog? Also, being owned by Google doesn't mean that you should rank well for Google. The same SEO rules will work on Blogger blog. I have no problem getting traffic from my satelite blogs which are on Blogger.
Maybe google started to wipe out crappy sites from their database ! search : blogspot to see what it returns ?
