Hello. Recently i found out how to find dofollow blogs, but i was wondering what's a good method to find out the blogs PR? I know there are a lot of PR checking tools, but maybe there is something that can scan the website and show the highest PR blog posts there are? Thanks.
Maybe you should try finding them by using scrapebox. It's a great tool that many people uses to harvest high PR urls from the search engines. It might take quite some time though. Maybe give it at least a month before you can call yourself really good at it.
SeoQuake is a free plugin. It lets you check out the PR of sites in search results on google. Get to google search settings, click advanced, choose 100 search results. then enter a search like this: "your keyword phrase" +blog +"leave a comment" (use the inverted commas) Once the page has loaded and SEOQuake has found the PR for each result, you can order it in ascending or descending order. Be carefull to make it look natural though with the backlinks, you should have about 30 low PR links for each high PR link otherwise it looks high PR loaded and google are not foolgle... Mix up the anchor text as well and link to sites that link to your site as well to mix things up.
You could either go free and spend hours doing it, or shell out the $57 for scrapebox and drastically reduce the time it takes
I tried SEO quake, but it was so distracting I have to keep it turned off I turn it on when I need to do a search, and then turn it right back off!
Dosius already give the good advice for free mode. For paid mode, scrape with ScrapeBox, it will save your time for sure.
