I hope some of you will be able to help.
One of my client's has a website that seems to have been hit by Google as it dropped down the SERPs for almost every keyword about 10 days ago.
From what I can tell it looks like there were far too many outbound links - around 20 per page, and it looks like Google may have seen the site as some form of spammy blog.
There are a number of advertisers featured on the site and there is also a guest blog. We have added no-follow tags to all of the advertisers and removed all outbound links from guest posts, but still havent seen a massive change in Google rankings.
Does anyone have an opinion on what else we could do to prove to Google that we aren't a spammy blog site?
