This is an anonymous account for obvious reasons. I also did the same job as the AMA OP, used this linkbaiting technique for over a year. Posting as I think HN would be interested in the results. Tens of thousands of optimised backlinks, Quality trusted links from major news publishers (almost all of them), Search traffic up from 30k a month to 200k, 800k to 1mill visitors a month. The infographics game is almost up…
I couldn't quite understand how it works. Was the idea as simple as just creating the infographic, then putting it somewhere on the site you want to juice up? (There were details about links I couldn't really follow on Reddit...)
