Few days ago I launched a site and apply seo works on it, and submit it to social bookmarking sites, and in next few days my site got fully indexed and started receiving nice traffic from google pointing to mostly pages at good position. But today my site disapeard from google, even main page is not indexed. I dont do any spamy work or link building spam. Then why my site sudenly disapeared from google.
I had this happen with a domain I have "seoarticle.net" it was well indexed then just nothing one day. I have tried everything to get it indexed, added pr5 back links and nothing. Guess I wont worry to much about that url for another year or so.
usually new page/s rank faster for a couple days... and then disappear after a few days or weeks... noticed that on some of my pages... just continue link building...
we are close to a pr update. google may make stupid think like that. in my opinion, you must wait and recheck after 1 or 2 weeks
the same thing happened to me, my home page disappeared from google this morning... its back now, but as the non-www version and it has slightly lower positions in the search results
Well it is very possible that you received an initial boost by google due to getting backlinks from your exposure from the social bookmarking site, if your site is new enough this could mean that google now found it, and it has either sandboxed your site or sandboxed your links, keep working on it seo is a long term process and doesn't include just one boost. The problem with relying on one boost is that spammers also are working hard on these boosts, and so are people who set up low quality links hoping for affiliate sales or clicks, cpm, which is nothing wrong with it, but google knows this and since it hops for the best content, it wants to make sure your site is legit...good luck!
My site come back today, yesterday there was no one page, but today some pages apearing in search results. So, now I am cool.
Hmm... I wonder if some of those topics you're covering had something to do with it? Links exchanges and even the comments about Google. I didn't read that much, but those topics came to mind.
