Hi guys,
I have a question i hope you can answer for me.
A little under a year ago i bought tons of blog posts from people on gfy where i wrote the text, added 2-4 embedded pictures from my sites and added 1-2 links.

I tried this method on a few of my sites for a while but stopped eventually.
I can really be conclusive as to whether the posts were beneficial or not.

I didn't really have too much of an increase and there were so many pandas and penguins running around that it was hard to see what was what.

I would appreciate any info you can give me if you have any experience, positive or negative using blog posts as a backlink method for your sites.

Thanks
