Need someone to point me out what to do. Let me get straight with the point, I have a client website whose ranking are good and stable. Problem started when i found several 404 pointing to the client site. I deleted those page from server and redirected few of those page to home page. Those pages where some how available on server. The pages have nothing inside just simple iframe code displaying e-commerce store of some other website which were not related to client's (I confirmed with them). The external site create several links to our website, which i am not sure where it comes from. I checked in site explorer to see from where links are pointing toward the site but found nothing. Redirection work fine, Google now show no more errors. But lately after making these changes, I noticed bounce rates and more traffic due to 301 redirection, which as expected. What's was not expected is ranking drop with many keywords that were good position. What I did wrong? Can you guys point me to outcome this issue? Thanks in advance.
