Just a little story I felt the need the share with the community seeing the drastic changes Google are making in the SEO industry. I started to try out public blog networks last year when a few people recommended them. I decided to try it, no harm trying right? I signed up for 4 of the most recommended networks - UAW, BMR, ALN and AR. Tried and tested each one of them thoroughly and eventually quit BMR and AR as they take too much effort and the ROI is low. I was hardcore doing UAW and ALN, sending out hundreds of submissions each day. Usually a few weeks later, I'd hit page 1 easy, outranking those sites with rented high PR homepage backlinks without even paying a cent (literally). It all worked fine until a few weeks ago when Google started targeting and taking out these blog networks one by one. Shit just got serious. It first started with a wave of deindexing on all the networks. About 25% of my links were gone with that single strike alone. ALN alone had around 6000 blogs deindexed. My ranks still held steady, but from that moment on I knew I was on shaky ground. My rankings could drop anytime. I decided to take my chances and continue submissions to these networks. Well what do you know? A week later the entire BMR network got nuked by Google and ALN is next. Matt Cutts said himself on his Twitter account that they're going to take out ALN (albeit indirectly). Not something someone like him would say unless he meant business. Hundreds of my high quality BMR links gone just like that, and all those posts were expensively outsource mind you. They only accepted unique content. ALN is going down one way or the other, no matter what they do. ALN 2.0, ALN 3.0, heck ALN 10.0 won't stand a chance against this multi billion dollar giant that can squash it like a little bug. Right now all my rankings have taken a dive. I did diversify and my rankings didn't go down drastically as my sites were of extremely high quality, but every keyword I targeted for has now dropped. Moral of the story is to either get your own private network and mask it wisely (STAY OUT OF SEOHOSTING) or just avoid these networks completely. They're going all out now, just look at Panda 3.4. Time to completely revise my SEO gameplan. You should too if you've been doing what I did. Change, adapt, evolve.
