A few years ago, I decided to try one of those manual directory submission services. Didn't cost much and a couple hundred directories ended up keeping my link without having to link back to them. The anchor text was mixed up and the links were added over a few weeks to look a bit more natural. After 4 months, I didn't see any gain in PR or ranking for the targeted keywords. I did bi-monthly rank checks using Advanced Web Ranking software so I would have seen any positive gain. Never really tried directories again. I see people talking about this directory is PR4 and that one is PR6 or whatever but the fact is that is just for the domain/index page. The page that YOUR link is on is probably a PR1 if you are lucky but usually PR0 or without a PR at all. So I'm wondering, has anyone seen actual, verified increases in ranking from directory backlinks?
