Why does google keep de-indexing my site?

Hi, I have a site that ranks for the top three results for a particular keyword. When that site is indexed, I get about 200 hits a day and convert at least 5 sales a day via amazon affiliate program.

However, the site is only indexed for a week or two, then all of the sudden its completely off the first 100 results, I don't think its listed at all even after that.

The site has a PageRank of 2, and about 50 backlinks. Everytime this happens (has happened three times now), I request reconsideration via the big G webmaster tools and 2 weeks later its back to the top 3.

Whats going on and how can I prevent this from happening? Is someone targeting my site and somehow exploiting the big G to penalize me?

new site often get shot up to top page and then deindex because of the so called google dance.

continue what you doing, posting articles, building backlinks naturally and you will see your site up again sometimes within few days and sometimes weeks.

theres nothing you can do about it but continue building it naturally.

The site was established 5 months ago and was recently given a PR2 bump. I mean I understand the dance, but to go from #3 overall to out of the first 100 results is insane.

And my point is, whenever I request reconsideration, it's back to the top 3 results again.

None of my other sites do this extreme of a dance.

Something is wrong. I personally never heard this kind of dance. Maybe other members can help you.

Yes, it is very strange.

Literally traffic is at 150-200 hits per day, then its gone to maybe 5 hits a day. I request site re-consideration via webmaster tools, two weeks it comes back to 150-200 hits for a few days, then its gone again off their index.

The site shows up when i do "site:www.siteaddress.com" in google, but it just does not show up for my keyword.

Could someone be maliciously doing something to my site? Or is this just a flaw in googles algorithm?

Wierd your site is not deindexed if you can find it when you do "site:www.siteaddress.com" if it was dropped from the index then you would get no results at all when you search "site:www.siteaddress.com".

Does your page drop down the SERPS when you have done some work on it like link building, this sometimes happens, does webmaster tool's give any help, is there anything stopping the site being crawled. Are you using too much flash? if the site is still only 5 months old it could be it needs a bit more time to find its level.

The "Google shuffle" / "Google Dance" (what you're talking about) has happened to probably 75% + of my SEO-dependent sites.

It's a regular thing.

"popular interpretation" is that google is reindexing / readjusting / testing alternate algo's.

There's really nothing you can do about it.

My advice: relax and keep your head down, keep building the site / backlinks / activity.

If it affects your cash flows, find other traffic sources, or build other sites - eventually things settle, and probably 60% of the time when the shuffle happens, my sites are ranked higher than they were before it.
