Is this the Google Dance?

I recently opened up a MNS. It used to be on the third page. Recently its dropped off the rankings completely! I can specifically search for my site and i will get results but i wont find it when i search for my keyword and i've checked 20 pages lol.

So my question: Is this kind of thing normal and will my site come back?

This can be a dance or you have been slapped by panda.
Tell us more info about your site. How do you build your links? blackhat/whitehat ? What kind of backlinks did you used ? How many ? etc...

Also, use a tool like market samurai -rank tracker, cuterank or other online serp checker so you can see where is your site.

Try also to check site:yourwebsite on google to see if it's indexed anymore.

As we all know that Google algorithm is a process and it happen after every specific period. You are one of the sufferer of this phenomenon. For this you have to be active and continuous backlink your site.

2 MNS of mine has been up & down if there is a panda update. guess its not dancing guys :-/

I got some work done from backlink fuel - PR Blitz but that's about it. Actually my site dissapeared after i got that done...What do you recommend to keep up my rankings? Should i do the backlinking myself (i have no idea how to do this) or should i out source?
