what are the benefits of Blue hat SEO and Grey hat SEO.

[Sonika11Mehra]

Blue Hat SEO : It is essentially the study of advanced Internet marketing & SEO techniques. Blue Hat SEO covers the advanced knowledge of both Black Hat and White Hat SEO. Everything on BlueHatSEO.com will assume that the audience knows & understands the basics of SEO and Internet marketing. If you think of BlueHatSEO, It helps as the creative aspect of SEO.

Grey Hat SEO : It is the practice of using technically legal methods to improve your site rankings, but which are ethically dubious, and could one day become the black hat. Think of it like legal highs. They might be legal today and get you high, but in a couple of years time, you could get punished for using them when the law changes to catch up with the new compounds on the street.

I don't think the other two exist - white hat and black hat are it -

Bluehat is an seo blog - it's a good blog

Blue Hat SEO is the combination of SEO and internet marketing and Grey Hat SEO is the same like Blue Hat SEO.
