1. Set up hardlink trades to boost your page rank. This will help you get better placement in search engine results. Also set up traffic trades with other TGPs. Then buy traffic to get your trades off the ground. If you're looking to buy traffic, I recommend
TrafficHolder. You can buy traffic by niche, by geo-location, or by domain, and they filter out all the garbage traffic. You can also choose which domains to buy traffic from... or which domains to exclude. You can stop, start, or tinker with your order at any time through a simple control panel. Plus their prices are very reasonable.
2. Sponsor affiliates generally will post galleries to your TGP. Set up partner accounts to help cut down on spam galleries with redirects and crap like that.
3. Can take a lot of time in the beginning while you're working on #1 and #2 (above), then after that, 15-30 minutes/day.
Good luck!
