1. When building tier 1 web 2.0 and blog links, how many do you suggest that I build per day.? I want longevity in the site, so I need to play it safe. It's an ecommerce store. 2. Can I use spun content for my tier 1 web 2.0 and blog links, or should I use all original content? 3. Should I also create a 2nd tier, or just the 1st tier and use GSA to build links to that? Thanks so much for your help!
