On a lot of my sites I'll post many inner pages with good content that has to do with the wider niche, but they're not pages I care about ranking. I usually only want my homepage and one or two inner pages ranking, everything else is just there so my site isn't redflagged as thin affiliate site and so I gain authority in the niche. These extra pages do bring in some traffic and it's semi-targeted. My main issue is that I still want a balanced link profile for my site, offsite and on. Doesn't look great if it's my homepage and a couple inner's that have all the links. But I post new articles daily to a lot of these sites, and getting most these pages backlinks is a pain. Right now I do a mix, I backlink some, but even with that, I wonder how much good it does. It could even be risky if some of those links get me Penguin'd. I figure a number of you must add extra content just to beef up your sites, content that's not targeting your specific keyword(s), but maybe the wider niche... so how do you handle backlinking it?
