my site is not in 100
 

my site is not in 100 from last 3 days why so and now what should i do ? but before it it was showing in 6th page

What website is it? Perhaps the keyword you're aiming to improve its rank on is already flooded with competition.

You should wait 2 days. After that it will come back on same position. I faced same problem last week with my website.

There was a related report on this I've come across one time. It says that Google mistakenly identified some sites as Parked Domains. Check it: http://searchengineland.com/dropped-...domains-118979. But the issue has already been fixed. That could be one of the problems. Another problem could be that you haven't really optimized your site well enough and others might have taken over your position. Can you give us the link to your site?

you should have patient for the seo.

you have to work hard for ranking, article submission, social bookmarking is best way to rank, i think.

I think you should work for your targeted keyword and get result.

Good Luck,
