So I've actually started to make some decent money on one of my sites. I am at about $600 so far this month, and I've been doing better every month. I've spent about ~200 on fiver over the last year buying various gigs relating to custom advertising, and SEO. At this point I am wondering if I should focus on trying to rank more keywords for my money site? Of if I should focus my investments on buying tools like GSA, blog network access, etc..(I own scrapebox, and run my site on a VPS), Or if I should start buying established sites from flippa etc.. What would you suggest? Basically, Should I spend money improving my money site? Or should I use my profits to focus on setting up/buying new sites and tools?
