I realize that the term Backlink is sometimes used in the wrong way on the internet. By the way, you know what a backlink?
I decided to make this short article just explaining what Backlinks are, External Links, Internal Links, Inbound Links and Outbound Links in addition to the difference between a Link Dofollow and Nofollow.
The term External Link (External Link) does not really mean anything.
It can be a link from my domain to your or vice versa, but in most cases, people working with search engine optimization, consider External Links the same as Backlinks
Note: While all the SEO community to use the terms in English, in this article I write them in English to become familiar with the terms.
Say you have a Site A, with mysite.com domain and a friend of his has a Site B, with the domain yoursite.com
What is Backlink?
Is any link that points to a page within the site A. These links can come from other sites or from within your own site.
Inbound Link (Input Link)
Is Any link from site B that point to your site (A). Some people also call it the “external link”, but as I said earlier, there is no longer correct.
It is as if the Inbound Links were a subset of Backlinks.
Outbound Link (Exit Link)
Any website link that points A to site B is an output link (Outbound Link).
Is Any site link A to point to the very site A.
Most of the internal links are actually navigation links.
If you do not use them on your site, I recommend a lot to do.
Any link in the above categories can – if the Webmaster want – be transformed into a nofollow link.
In this case, Google sees little or no value in it for SEO purposes.
The nofollow links have the attribute rel = “nofollow” in your code.
Any link that does not have the nofollow attribute – either intentionally or accidentally – is considered a dofollow link.
These have a direct impact and often positive in your Google rankings, even if the Internal Links.
