This is a method I borrowed from SEO specialist from Ukraine who made the script for it. Here's his blog http://mz.kiev.ua/blog.html . I'll share this method and another one of his later, the other one allows to find a list of keywords that none of your competitors use in PPC. If you know russian you can read everything here: http://mz.kiev.ua/blog/api-serpstat-7-scripts.html Things you'll need: 1. Access to Serpstat's API. $49 or if you have a friend using it you can borrow a token from them. 2. This link: http://mz.kiev.ua/tools/serpstat-get-forum-threads.php 3. This thread or knowledge of Russian language (Reading this thread will be enough to understand what's going on there) Let's go. Open the page from that I linked above and this is what you get that's pretty much all the russian language that you need. Here's how it works, i'll run guitarcenter.com through this script: I chose to find forums relevant to 50 keywords from guitarcenter.com in google us. Here's the data I got: Total number of forums that I've found is 33. Keep in mind that I only ran analysis on 50 keywords, depending on the number of keywords you want to analyze from your domain you can find thousands of domains. All of the pages in the list are relevant forums where your target audience hangs out.
