I gave this a brief trial, and I have found that for commenting on related .edu blog posts, this free tool is great.
It was great. Now it is gone and I can’t find anything like it.
So, it’s back to google searching site: .edu keyword
So your backlink campaign should consist of authoritative, trustworthy sites that sit in good neighborhoods such as .EDU blogs. Our tool will return results to relevant one-way .EDU blogs to leave comments that backlink to your your website. We highly recommend you leave meaningful comments on these blogs or a moderator may remove your comment thus wasting your efforts.
