Yes method and not methods as there are many discussions on the net already on how to find a good seo provider. But for my method, I can sort out those so-called "white hat", "100% legal", "no auto backlinking software used"....etc and tear off their fake mask in just a few minutes. Open up Traffic travis, go to "SEO" ---> "Backlinks" ---> "Pages To Analyse" Next input one those portfolio websites url to analyse that the SEO providers provide on showing off their page 1 achievements. To your surprise, you can find many "white hat" links they talking all day long are actually blog comments posting with OBL over 100s, and also with viagra, porno, gambling urls. Yes some of them do rank well for NOW, but I believe will not be long and will be penalised by Google when the next update arrive. Do your due diligence and you can weed out many "white hat" seo firms which charge alot more than it worth.
