If you are a webmaster, you would have known this, the more sites that are linking to your site, the more traffic you will get. That's trully a fact, there're no webmasters would doubt it. Many webmasters are trying hard to keep their Alexa rank as lower as they could. Though even I could not understand what are alexa based for ranking the sites. On alexa website, it only said that many inbound links can help improve your rank in search engines, and can serve as a measure of a site's reputation.
You would also probably saw an advertising about buying link from PR9 sites. Infact you wouldn't have to spent a dime to get backlink from a PR9 site based on my experienced in this blog. Try to click on my alexa widget on the right sidebar! Click on the reputation # of sites lingking in! Look at what's the #1 site linking to my blog!
Yeah!! That site is blogger.com, a PR9 site with alexa rank 43 (last time I checked). How did I get that PR9 backlink for free? If you already have Google account, whether you have blog or not, you must have a blogger profile. Fill your blogger profile with your site!
And then, if you have already blogger profile with your site on it, you must have been wondering, why my site didn't get a backlink from blogger.com? Actually, there're 2 ways to get a backlink from blogger.com. The main thing is, you must comment to other sites, especially blogger blogspot sites, using your Google account. The second is, your comment must be unique, so that it can drive the other visitors of the site who also read the post, to view on your blogger profile.
The more people viewed on your profile, and visited the site on your blogger profile, the faster you get the PR9 backlink from blogger.com. The truth is, by commenting to other blogs or sites, it will drive traffic to your site, at least an exchange visit from the site owner. You shouldn't have to place your site link, using html text, with an anchor text, for an intention to get dofollow backlink from the site. It would be considered as a spam comment, and the site owner would not publish your comment.
