About Inbound links...

[Jeffreyhooft]

Inbound links generally known as back links are the links pointing to your site and search engines like it when you have thousands of links pointing to your site but sometimes Google penalizes you for it too if you have poor quality and unrelated back links pointing to your site.

[Randalerarm]

An inbound link (also referred to as a back link) is a hyperlink on a third-party web page that points to a web page on your site. Inbound links are important for search engine optimization (SEO) because Google and other search engines see multiple, relevant inbound links to a page as a sign that the content on that page is useful.
