Hi, any o you knows how long it take a link to make difference. in case the link is a high quality link.
A single link? More than likely it won't make a difference unless you're in a niche with almost no competition. If that were the case, I would give it at least a few days after the link has been crawled and indexed to see any difference. Although you'd be better off building links in that time rather than waiting to see how far a single link gets you.
well this is my case, I have been working hard to get links pr3+ and I have increase the back links in about 1000 links from pr0 to pr3 but I don't see any difference in traffic or ranking.
Here are some things to consider: -If you're getting a lot of links from a single source (like a blog with top commentator plugin) then the links will be devalued. -What pages are your links coming from? A PR0 page on a site that happens to have a PR3 page doesn't mean you're getting the full effect of the PR3 page. That PR0 page and only leach and share so much PR. Getting your link on a PR3 page would be much better than a PR0 page on a PR3 site. -Check your on-page SEO. It's very important.
these factors all depend when talking about rankings....depends on the quality of backlinks and the keywords you are targeting
One single link will not make a difference. The difference is made by a setady flow of new links being found every day, these don't even have to be high PR etc to count. Just build steady links every day for a week, maybe 20per day and you will see results. 1 link will not help.
Post links steadily. By adding more each day you will have a much higher impact. One link does little to nothing on it's own. It's all about build up.
