Hi guys, i was away from the SEO field for quite some time. I guess my question is does guest post still workable? from what i heard from Matt Cutts that all blogs now should be no follow so guest post doesnt give you the backlink. Do people still do comment on blogs and get backlinks? does it still work? what is the most effective seo method now? Some say AMR is dead because of the quality of the links how does all those tier 2 and tier 3 building work now when the backlink from blogs are no followed? It really feels like SEO is dying.
