Frankly i've been DIY SEO for quite sometime. Still learning & doing it at the same time. Results have showed, although not that convincing due to my lack of experience & knowledge.
Just cross my mind why not just Fiverr, Odesk, SEOclerks or etc. But then again, is it worth to take the risk? 500 people (positive reviews) can't be wrong? Right?
Looking for certainty here.
