Hey guys. So about 6 months ago my site was #1-#3 for 10 mid competition keywords. It was doing well. Then google's famous updates came along and screwed it all up - I'm sure many of you can relate. I can't even find my site in the top 100 search results - although it does still show up #1 for the main keywords of the site. I want to get back into the same niche as it was quite profitable. So my question now is does it make sense using the same site or should I just start fresh? I used a lot of spammy backlinks, and crap content the first time around. Thoughts?
