Does anyone know why my website's URLs in Google web index has dropped to "0" ? It shows I have +350 link on my xml file and last week I had +150 URLs in web index. I didn't do any changes to my XML file.
This happened to me a few weeks ago. I redid a section of my site and then my urls and backlinks dropped to zero. I think it had to do with Google being in the middle of re-analysing my site. I waited a week and they all came back.
It may also have to do with Google's new algorithm, but that is complete speculation. I'd recommend just waiting to see if the urls come back.
