Have question regarding tier 1 web 2.0

Hello

I have created wordpress blog with 2k content on it. (Added all contact, privacy policy, about us ...) and it was indexed right the next day.. The start ranking was at spot #50... When i started poiting backlinks to it, the ranks disappeared and didn't came back yet .. I was doing wiki, blogcomment, bookmarks, social signals and web 2.0 to it and all from quality providers and not fiverr or some junk...

Anway is possible that my tier 1 wordpress went to google "sandbox", because the blog is still indexed and i need just to wait some more time to see it back at rankings ?

Its new website you need to wait few weeks. Just keep building links, After recent Google update its normal thing "Getting disappear in search".

Yes this web 2.0 is new.

The links you have built are generally junk - doesn't matter which provider they are from.

A lot of sites bounce up and down - I'd wait and see what happens.
