Back in 2012 I owned a successful article directory, PR2, good traffic and good earnings from Adsense and links. The quality of the articles was not good, the usual spam produced by tools, some of it really bad. One day in GWT, I got that email that everyone got who owned a directory, about a violation of Google's terms and that my site was deindexed. I decided to keep the directory, and I made a little money from charging people who don't know how to check that the site was deindexed for link removal. (Why is the world so full of people who think you are going to be ecstatic at the prospect of working for them for free, cleaning up their SEO mistakes by removing links? How did remoov build a business on this? Who actually removes the links?) Everything remained the same, the good old status quo, until last week when I got another email from GWT telling me that there might be a problem with my site in that not all my links were successfully crawled. My first thought was what? Next I did site:nameofmyarticledirectory.com in google and rather than zero hits like I had seen for over a year, I see over 7K hits. Google is slowly reindexing my site! So everything that was old and deindexed is new and reindexed again. I've even got the question mark in the google PR checker for a new site. Stuff like this just make me smile.
