This is a stupid little trick I use to find blogs and articles that I can post comments on. I set up google alerts with my website name, my name and my main keywords. Whenerver I get an alert that mentions my site or my topics I post a little comment and sneak in my link.
Good trick, I use this a lot. I get about 50 - 100 alerts a day that I glance through and choose blogs to post on. Topics for each one of my clients.
