Just like White Hat SEO
and Black Hat SEO
, there is another kind of SEO known as Grey Hat SEO
In Grey Hat SEO technique, we take some risks the way we promote the website. We do something which is against the SEO guidelines. But the risk is not that enough to ban the website.
Paid linking is one of the examples of Grey Hat SEO.
Any additional info about Paid Linking?
