What is link buying?
I remember my early days in SEO, when the word "link buying seemed almost taboo to me. And yet, it's a common practice, sometimes even essential to any SEO strategy. Simply put, buying a link means paying for another site to point to yours, in order to improve your visibility on Google.
It's important to distinguish between a natural link - obtained without financial consideration - and a sponsored link, which is clearly remunerated. This distinction is important because Google prefers the former, even if it tolerates the latter... under certain conditions.
As part of the Off-page SEOThese links play a key role: they transmit authority, also known as "link juice". In other words, the more good links you have pointing to your site, the more credible Google considers you to be. Fascinating, isn't it?
