Google has dropped my site under two different domains.

I have a site that was dropped form google search results and I couldn't figure out why. After about a month I just decided to start over with a new domain. I bought the new domain and forwarded the old domain to the new one to keep the existing traffic. I moved the site to the new domain. Updated the meta data and even alot of the content. Everything was going good for about two weeks and then today gone from the search results. Please help!

Here is the site.

http://www.mostmusicvideos.com

 

The script your using is flagged and google take them out of the index.. wanna buy some videos site? I got a few.. all are banned.

 

How do you know that it has been flagged?

 

Google give a New Content Boost to new pages and new sites, this boost helps them rank high in search results. But this boost is only temporary.

May be your site also had this boost. And now your site is gone from the search results because this boost is temporary.

 

I don't think so because the spiders stopped coming to both urls.
