Google strange filter - HELP! PLZ :)

Hi!

I own several sites - some of them are porn. And some of them are 100% stable in serp and some are changing its position that way:

Friday - top 10
Saturday - not in top 1000
Sunday - Thursday - 600-800 position

Can anyone help me with this filter - whats the right direction to go away from this?

Thank u!

PS I can pay if this hepls

weird stuff. pretty weird. i haven`t seen such thing

Have several sites with this problem.

Isn't it what's called Google Dance?

Sounds like googles dancing to that sweet backlink music!

LOL... will read now... here in Russia it is a random thing.

What's the best guide to go out from this filter?

It's not a filter. It's just Google updating it's index (In case that it's really Google Dance). If so, just wait for a while and you'll be alright. Search "Google Dance" on.. ehm.. Google and you'll get some info

I got u. For one of my sites this problem occurs regulary every week so I do not think it is a kind of dance. I think it can be a filter.

UP!!! Still need hepl
