I recently acquired this new client for SEO work. He had a previous SEO guy that worked for him full time but they had some sort of dispute and he was fired in November. The owner told me that he didn't get along with another employee so they were both let go. Until the end of September, my client's site used to get over 6k hits a month and he made good sales. Traffic abruptly stopped exactly a month before this guy was fired. This leads me to believe that he was doing some blackhat stuff and may have been sandboxed. Furthermore, the site practically had no SEO on the landing page and was poorly structured. This site is 10 years old and has a PR0, it should have at least a PR4 by now. I looked at some of the competition and most are ranked at least a PR3. I convinced the owner to build a new website from scratch on another host because the one he has now really sucks but that will take a while. In the mean time I'm doing a little SEO on the current one but I'm not getting results. I've only been working on it for month but I'm almost getting nowhere trying to get some of his keywords ranked. Traffic has picked up a little, averaging about 80 UV's a day. My client and his partner have no knowledge of SEO and didn't even know exactly what the previous SEO guy was doing. Here are some of the things I discovered that my client got screwed on by the previous SEO guy: 1. Files were deleted off of the server such as the sitemap and robots.txt 2. He had previous Adwords set up and all campaigns were deleted 3. Meta tags and description were deleted 4. Deleted google analytics tracking I'm sure other things were done wrong but that's all I know for now. Anyway, back to my original question - how can I tell if this site was sandboxed and any suggestions on how to straighten out this mess. I've already taken care of the obvious such as the deleted files and SEO'ing the landing page. I've also done some campaigns such as BMD, Web 2.0, a few articles (I know I need to do more), a lot of backlinking. I'm sure this is where the traffic is coming from now. Your input will be greatly appreciated.
