I don't know what is going on, but my Google backlinks sat at single digits foever, then dropped to zero and now shot up into the thousands according to one source. This is driving me nuts. YAHOO is steady as always...
Here is the page that gave me the results that I am wondering about...http://www.mikes-marketing-tools.com/link-popularity/
I had exactly the same with google, although during the last week yahoo has been bouncing around too. One morning I had 300 backlinks, later that day I had 2 then the following day back to 300. I don't know of any other way to check apart from using SO firefox tools.
If it's steady as per Yahoo Site Explorer, i don't think there's any cause of worry. YSE is more or less the gold standard for backlink count. Is there any changes in your GWT link count ?
I am getting 536 Backlinks in Yahoo.. but zero in google and bing ?!? I don't know how it is showing like this? Even many of my links are cached by google...
I had 159 yesterday on one site and now its at 52. I should have many more backlinks. The google backlinks is defo actiing weird
I have experienced the same with dropping but a little and not wiped off to zero anyway. I just found the backlinks updated today either.
Yeah Google is annoying when it comes to displaying backlinks. My site jumped 4 pages, but according to Google I didn't get a single new backlink in many weeks.
I've found the amount of backlinks registered can vary from one program to another. I maybe wrong but with your varience in backlink numbers it may have something to do with the Google update/Dance?
