Whats the best thing to do after rebuilding a site to get old rankings back ?

[footballearnings]

A website changed its platform from the old one to magento ecommerce. In webmaster tools google says that yesterday was the last time that crawled the site, but the old rankings for keywords are gone , traffic went down big time and now i'm not sure where to start working in order to bring everything like it was. any advice ?

Buna Radu,

How hard was the website hit? Could you maybe provide a link to it, so I can have a look?

Yikes!  I would reupload the old site!

Did you change the URLs of the pages?  If you did that then 301 redirects will be needed.

Or, did you change the page optimization?

Really.... you have provided almost no information so all that anyone can do is guess.

The structure is new , the urls are new , content is the same + some new products (new content), so pretty much everything changed. page rank is still the same but the ranks from the keywords ... . from 2000 unique visitors per day we now have 400-500. the website is www.medicamente24.ro .
