I have read the FAQs and checked for similar issues: YES
My site's URL (web address) is: http://www.barcelonaphotoblog.com Description (including timeline of any changes made):Some days ago I had an incredible amount of backlinks, hundreds of thousands, which was of course an inflated figure cause for Google I only have 158 and for Yahoo which is more precise, a little over 30000. Today I have no links at all, neither I have in the rest of my blogs. Sitemap is working perfectly (it wasn't not so long ago). I am afraid this may be happening to more people and I was not able to find an official explanation. My opinion is that this could be due to some internal Webmasters tools tweaking in order to fix the problems with inflated links. Do any of you experience similar problems?
