what is meant by Grey Hat SEO?

[Uzzal]

Gray hat SEO is SEO techniques that take more risks than white hat SEO techniques but aren't likely to get your site banned from search engines. They're questionable SEO techniques but not in the same category as black hat SEO techniques. However, what's considered gray hat SEO today might be black hat SEO next year.

Gray hat seo is a combination of black hat and white hat seo. it is wrong way to do promotion because in the gray hat you are using black hat techniques. so i suggest you don't do that do only white hat seo.
