Which types of backlink code and structure are best for SEO?

1 answers:

Before we proceed with reviewing the standard backlink code and structure commonly used for SEO purpose, let me begin with some basic definitions. Put simply, every backlink (otherwise, inbound web link) is born when one website has a URL leading the way to the other third-party source elsewhere on the Internet - by way of making a reference, or adding that URL. And the whole set of inbound links created for the website makes its link profile. That way, the major search engines like Google and Bing are using it to determine the real value, popularity, and importance of each website or blog at scale. Considering that not all of them are created equal, just spawning backlinks at random for the sake of their maximum count will never do. When it comes to organic link building for SEO purpose, the thing is that only link quality matters, rather than their quantity. 


As I already said, not all of them are born equal. That’s why, before anything else, let’s make difference between the following two main types of web links. In fact, they are distinguished by HTML peculiarities in backlink code, as well as the standard impact on every website from the viewpoint of SEO. 

  • DoFollow backlinks are used not only to connect two separate web pages and “pulling” them together but to transfer and redistribute quality metrics on both sides. Speaking in general terms, backlinks with DoFollow are often recognized among the most decisive elements, when it comes to awarding search ranking positions. This type of web links is used to give a standard evaluation to PA (page authority), DA (domain authority), PR (PageRank), and the rest of metrics like user trust. Most commonly, such web links with a DoFollow attribute in their backlink code are inserted into news releases, as well as blog or article posts. Sometimes they are found in forum posts and comment sections.
  • NoFollow backlinks are designed to connect two separate web pages, i.e., mainly for navigation purposes solely. It means that a NoFollow backlink code attribute doesn’t make allowance for page or domain authority transfer (a.k.a. link juice). Keep in mind that this seemingly insufficient difference makes much more sense in terms of crawling and indexing, as well as major metrics evaluation.

Backlink Code Structure in SEO

What makes a basic structure of backlinks in SEO? In fact, every inbound link consists of the following core elements: hypertext reference tag, anchor tag text, link reference, and closing tag.

  • Every backlink is born with  “<a href”.
  • Next comes link body text, which starts with backlink anchor tag “</a>” to tell the search engines web link is about to follow, it’s also clickable and has a special color indication to stay out from the rest of on-page text content.
  • Every hyperlink ends with “</a>” closing tag, which just tells the search engines about the closure of the whole hyperlink tag.
