Is there a tool for searching for (manual and quality) backlink possibilities, namely e.g. blog posts and forum threads? The usual way is to use scrapebox and filter, but is there a search engine available for that?: I want e.g to locate blog posts for a given keyword which are open for commenting, have max 50 #OBL and a pr of say min 3. Google cannot do this, right? Or I want to find forum threads which are specific for my url, I mean: the threads are not just matching a keyword which might occure in many non-related content. No, the forum thread should match in a narrower sense the content of a given url. From what I know from search engines, both cases should be possible to be implemented, right?
