I hope this is the right forum to post this issue, I've looked around and find no similar issue has been posted. One of my site has 526 url in its sitemaps. Till yesterday, in the Google webmasters panel, the report showed 526 url submitted from the sitemap, and about 517 of its were being indexed. few hours ago, the report changed to: 526 urls submitted, and 0 page was indexed. I did a "site:" query search, the result showing about 517 pages were indexed. this strange problem persist till the time I write this threads. anybody ever experience this problem? does it mean that my webs get 'banned' or something? or it is just some 'normal' temporary problem with G datacenter? hope somebody can give me a good explanation. help me out of this
This sounds like a glitch in the google web master tools report. I mean: the same amount is actually indexed as before. If your site were being devalued, it would be more likely to just get less and less pages indexed. Unless you are doing spammy things, a total drop from 517 to 0 is just not likely. So don't stress, just look into this again tomorrow. On the other hand, if this is accompanied by a sudden drop in traffic through google, than you do have something to worry about.
yap, I hope this is just a glitch. I've never done any spammy thing btw, I tried the "site:" query several times after I posted this thread, result were still normal (about 517 page indexed). Same result I got using websitegrader tools.
