Does Google provide this info anywhere? I don't see it in webmaster tools. After the April 11 update a lot of our SERP positions dropped and traffic dropped significantly. The content of these sites (which are specialized directories) have not changed much in the past 5 years except that more listings are added every day - so the information has grown and it is all unique (except for the related blog articles we post that are syndicated via RSS and noted as such and linked back tot he original publisher) The syndicated content makes up a very very small percentage of the content on the site - probably less than 5% of the pages are syndicated - the rest is original content created by our member listings. i would like to discover if people have been blocking these sites with the Google Chrome extension - so anyone know if I can do that? Or any way to find out if Google has devalued my site (besides the obvious drop in traffic?) PS - Admins: is a second image verification really needed just for previewing the post?
