Fast Trick to Locate Blogs!
Here’s another neat trick for finding Do-Follow, High PR blogs that you can leave a comment on, and thus garner yet another link to your website.
It’s a simple one really, simply search Google for "blog comments powered by Disqus" – be sure to include the quotes. Also include your keywords… so if your website is on Internet Marketing, then the Google search term would be:
Internet Marketing "blog comments powered by Disqus"
Then, using your Firefox ‘SEOQuake’ plugin (you are regularly using it, right??), simply sort the results by PR, and start commenting. High PR sites that are related to your website and that provide a do-follow link to your site is one of the strongest methods to raise your own ranking with Google, as well as raise your search engine result pages… so if you have a website, get busy!
[Update - This trick no longer works for Dofollow links]
