Noticing some changes to your Google Webmaster Tools data? Don't
Over the past couple of days there have been an increasing
number of reports about large decreases in the number of links
reported in the 'Links to your site' section of WMT (by as much as
75% in some cases).
Judging from what affected webmasters are saying in the
forums, the majority are confused by such large changes in the
data. Others are flat out panicking "Where my all back link gone
while I didn't use 'disavow links' tool????"
Most recently in a
Google Webmaster Help thread John Mueller from Google helped
calm the crowd, stating that it appears to be a bug.
So the good news is it appears to be some kind of technical
glitch, and the guys at Google are on the case.
