The best type of backlink

Getting backlinks from relevant and authoritative websites is the search engine optimization (SEO) best practice. These links help improve your website’s SEO profile.

There are numerous factors that make a link strong. The first, and arguably most important, is the HTML structure of a link.

For the purpose of link building, you want to earn links that pass the mighty link juice. This happens through a “dofollow” link within the webpage’s code. The “dofollow” aspect comes from a command in the tag that omits the rel=nofollow tag.

In this example, search engine crawl bots will follow (i.e., crawl) the link because nothing is telling them not to do so (e.g., a rel=nofollow in the tag).

Ultimately, there must be something in place that tells search engine crawl bots whether or not to follow or “count” a link. Conversely, a nofollow tag is used to indicate that you cannot be certain of the authority or trustworthiness of the external site page being linked to.

In 2019, Google rolled out two additional tag directives that are relevant for backlink profiles and outbound linking:

1. rel=”sponsored”
2. rel=”ugc”

The sponsored directive is used to indicate when a placement was paid for. The UGC directive is used to indicate user-generated content (i.e., content the website did not publish directly, such as a forum post or review).

Though some SEOs have hypothesized that these additional link tag directives are setting the stage for Google to possibly start allowing authority to flow through nofollow tags, there have not been any conclusive studies to date that confirm this is the case.

Check out Google’s documentation about qualifying outbound links to learn more about link tagging directives.

Factors that constitute a high-quality link

1. Link relevance

  • How relevant is the link to the page it connects with?
  • How relevant are the two sites to each other?
  • How relevant is the website that gives the link to the industry as a whole? For example, a page talking about flowers that links to a website about gambling is out of context and would not be considered a good link.

2. Link position
The best links are in the body of the content and need to be put in the copy by the webmaster. Links in the comments, footers, or headers of a page are usually seen as spammy and ultimately dangerous. This is a result of an old (and underhanded) practice of stuffing a high number of irrelevant links into these sections of websites. Google eventually caught on and subsequently devalued these types of links.

Hidden links (i.e., links that are not visible to a user until it is clicked) are especially risky as they are a clear sign of an attempt being made to trick search engine crawl bots into counting links that users cannot see.

3. Domain Authority or Domain Rating of the website giving the link
Domain Authority (DA) and Domain Rating (DR) are made up metrics (from 1-100) that Moz (DA) and Ahrefs (for DR) use to score a web domain as a whole. A brand new website with little to no traffic will likely have a DA/DR of 0. A more authoritative website, like Facebook, has a score of 100. It’s a sound practice to use both DA and DR when qualifying websites, but there are others tools to utilize as well (e.g., Semrush’s authority score, Majestic’s Citation and Trust Flow).

Page Authority (PA), a metric that indicates the strength of an individual webpage, is also an important factor in a backlink’s strength. You can identify PA by using Moz’s link explorer. From there, Moz will show you the authority of any specific page on a scale of 0-100.

As a general rule of thumb, the higher the DA, the better the link.

Authority & relevancy of link building

In addition to DA and DR, you can use other tactics to help determine a link’s value and identify the difference between good and bad links. Keep in mind that third-party tools’ metrics are generated with the intention of formulating a data-based perception of how search engines interpret a website’s authority.

Page authority & relevancy
You should always pay attention to essential information about the page that is linking to your webpage.

Pages with strong rankings within search engine results pages (SERPs) are better to get links from than those that do not rank well. This goes back to the link juice (i.e., value of a link). More specifically, pages with rankings in your industry are better to get links from.

Say your company just wrote an awesome piece on tips for buying a house. The absolute best case scenario (though likely improbable to achieve) is to get backlinks from all of the top 100 articles ranking for the term “how to buy a house:”

Authority tools for link building

While you can leverage Moz’s DA for strength scoring, you can also leverage other tools to understand the power of a link, including

  • Semrush: Use this all-in-one tool suite to understand if a page has non-brand traffic and keyword rankings that are improving month-to-month. Pages with more keyword rankings and more traffic have more value.
  • Ahrefs: Use this SEO software suite to look at competitors’ backlink profiles to find relevant backlinking opportunities. You can also use Ahrefs to look at your own backlink profile to find old, irrelevant, or broken backlinks that you should reach out to the webmaster to get updated to priority URL targets (i.e., URLs that you would like to drive traffic to in order to increase visibility on the search engine results page).
  • Majestic: This SEO software tool’s useful “topical trust flow” metric allows you to see where your competitors are receiving backlinks so you can better build out linking campaigns around these topic clusters.
  • Screaming Frog: Use this tool to quickly scrape websites (i.e., retrieve/extract content and source code data from them)to find potential linking opportunities through external links on blogs and editorial content.

In a nutshell, the most sought-after links are from websites with high domain and page authority, and these are the backlinks you most want to secure for your content. The best case scenario is to get a link from a high-authority site closely related to your own (e.g., same industry, similar audience).
