Is it okay for a Blogroll Link Exchange to link to a page? In other words, is it okay for my link exchange partner to link to a page of my blog rather than my main url? Because the plan for my site is basically to have 1 "super page" for each keyword I'm trying to target, rather than making a separate website for each niche keyword. Sound good?
It sounds like a good plan to me. It is a bad practice to build most links to a website's homepage. It is far more effective to build links to pages throughout the site.
