I realize this is a crude and possibly hard to answer question, BUT -- How long will it take to see benefits of a PR4 link? I mean -- does google have to see the link and index it all? Does this sometimes take weeks?
wait till the G indexes it... then soon after... btw hope it wasnt on a directory... lol otherwise wast of money.
Google's PR is updated almost daily on there end, however they do not publish it on there toolbar but once every 3-4 months. I do not see one PR4 link having much effect on your site. The link you bought, is the site you bought it from at least have anything to do with your niche or did you just buy from a random site for a cheap fee?
I agree...1 PR4 link probably won't help much at all unless it is directly related to your niche. It also depends on 100 other factors other than just the PR of the link.
The backlinks from the Quality website (related to ur niche) will consider for boost the PR. So, it will effect your PR in next google pr review. Keyword position is depends many strategies.
It depends on how much PR 4 IBL's for your website and all those pages from where you are getting link is cached or not. As soon as it cached with your link, you can see results in next BL's update.
The PR for a site might crash if you get incoming links from poor. you must make back links Quality websites that is boost your PR.
So I am confused. I thought the BULK of SEO was about quality backlinks. These are from related sites -- at least somewhat related (medical field). But yes they are amongst other links, but not on classic directories. Are they no where near as important as an article on an article site where there is many keywords and content near the anchor text?
It will give you benefit depending on several factors. Like now many outgoing links, the website linked you is related to your website or not?
