When it comes to link building, relevance is everything — both for SEO value and for improving the success rate of your outreach. For SEO, Google is constantly updating their algorithm to focus more and more on relevance, and this includes how they treat links.

If you’re an SEO professional or a business that handles link building campaigns in-house, it’s a good idea to brush up on link relevance. The same link building tactics that worked for you in the past will likely not be as effective now. Relevance is the direction Google is taking, so old tactics will be even less effective over time.

If you need to revamp your strategy to make sure your next campaign is successful, it’s time to focus on relevancy. Here is our guide to link relevance, what it is, and why it’s so important for the future of SEO.

What Is Link Relevance?

Link relevance refers to how useful and topically similar to a website is when they link to your website.

It is a signal that Google uses both for individual links, as well as your whole backlink profile. There are a few reasons why Google is placing more importance on the relevance of your links:

  1. It helps Google get a better understanding of what your business is about, such as industry, products, and services
  2. It helps prevent black hat link building from websites completely irrelevant to your site
  3. Google can break down the relevance of a link from domain to domain, domain to page, page to page, and link to page

As an example of the third point, let’s say that you run a cookware shop and a website dedicated to homes and gardens. The whole domain concept might not seem very relevant, but they might have a section of the website dedicated to cooking and cookware. Here’s how those four categories for relevance works:

  • Domain to Domain: Your cookware website has a light amount of relevance to a home and garden site
  • Domain to page: The home and garden site’s review on best cookware is highly relevant to your domain
  • Page to page: The home and harden site’s review on a specific cookware product that links to your page on that same product is highly relevant
  • Link to page: If the position of the link on the page makes sense contextually, or if it was placed randomly purely to manipulate SEO

These four levels of relevance allow for a more sophisticated set of link metrics you can use to assess a link’s value. It also represents the present and the future of link building.

Why is it important for link building?

The reason why relevance is so important for link building goes back to how Google treats links in their algorithm. Links have always been one of the pillars for SEO, going back to the start of Google. However, how search engines assess the quality of links has changed dramatically.

In order to prevent people from abusing unnatural, low quality, and black hat links, Google has evolved its algorithm to be more selective. The whole point of a natural link is that someone thought your content, website or product is good enough to share on their website.

In short, when you build links to your website (or your client’s website), you should be asking yourself the following questions:

  • Would you show the link you got to your client, colleagues or boss?
  • Would you show it to an SEO professional as an example of your work?
  • Would you show it to your friends, family, and website users?

If you think you should hide the links you get from everyone, from Google to real users, that’s a sign of a bad link.

That’s what Google’s algorithm attempts to do when assessing the quality of a link as well. That is why focusing on relevance is so important in link building.

In the end, it’s all about establishing link authority that Google can trust. The less relevant a link is, the more red flag signals Google receives that your link is low-quality and unnatural. Not only will that not pass on any SEO value, but it can also get your site penalized.

How to Improve Link Relevance?

There are a few ways to improve your link relevance, so you can gain greater success with your link building campaign. The first and most obvious way is something that Google says outright to avoid: don’t buy links or participate in a link exchange. If you have low relevance links, you can look into disavowing the most toxic of them.

The general idea is to be deliberate in focusing on relevance in every part of your strategy. That means you should stop and consider if the link is relevant for users with every step in the process:

  • When you research websites and opportunities for outreach
  • When you write content to generate natural links and for guest posting
  • When you set up the technical elements of your links, such as anchor text

Want to know more about you can accomplish all of that? Here are three things to help improve link relevance in your link building strategy:

#1 Outreach to relevant sites

One of the most common ways to get high quality and/or highly relevant links is through outreach. This involves either manual research or link building tools to manage it for you. The idea is to find other websites that are relevant to yours and open to linking to other domains.

For manual research, you can search for your industry or niche keyword and variations of link solicitation keywords. Here are some examples:

  • “Camping equipment” + “reviews”
  • “Beauty advice” + “guest posts”
  • “Home renovation” + “guest contributor”

This method helps you find sites that have at least some relevance to your niche. However, you will still need to check each of the results you find to make sure they are a good match for your site.

Each website should go through a careful vetting process. In addition to things like cost, you should be checking each prospect for the following link building metrics:

  • Relevance — the website, page, and/or link relevance is a good match for yours
  • Quality — has good domain and/or page authority
  • Backlink profile — make sure they don’t have toxic links that could affect you if they get penalized

For relevance, the should be in the same niche with some overlap in audiences. However, they don’t have to overlap in purpose — you don’t want to do outreach to competitors, for example. You want to find websites that provide a different purpose.

If you sell products or services, you can target websites that review such things. If you write content related to your niche, you can target websites that has similar content but maybe wants expert opinion.

A good example of relevant outreach is a business law firm reaching out to a blog that focuses on providing business advice. If they are open to guest posting, you can write all kinds of content for them where you give basic legal advice to business owners.

An example of poor relevance would be that law firms reaching out to a nutrition blog to pitch content related to business law.

#2 Write helpful content

The kind of link that Google likes most of all is one that you get naturally. It’s when another website likes your content and/or your products or services so much, they link to it on their site. The idea is that these links happen because you earned it by being trustworthy and authoritative.

That’s all well and good, but getting natural links is not easy. It all comes back to having highly relevant and high-quality content on your site. It must be the type of content that answers people’s questions and solves their problems.

If you do it right, people are more likely to link to your site and your content. They might even ask you for a quote or article to share your expertise. These are the best links to get for your SEO because they are purely natural and you don’t have to spend time with outreach.

Let’s say your business is a dental clinic, and you want to write good quality content to attract natural links. Here are some good examples of content to write for your site:

  • Signs of common dental health issues
  • Tips for proper brushing or flossing technique
  • Recommendations for the best dental health products to use (toothbrush, mouthwash, toothpaste, etc)
  • Review of services like Invisalign, Smile Direct Club, and other services related to dentistry

It is important for you to focus on writing content that is relevant to your niche and not stray outside of it. Take that same dentist clinic above. It makes sense to write any content that helps address people’s questions and concerns about dental health and related products.

However, it does not make sense to write about something like sports, TV shows, video games, or any other area of entertainment. Even other bits of medical information outside of dentistry, such as optometry or physiotherapy would not be very relevant.

It’s important to remember that your content can come in multiple forms, including some that are more likely to be shared and linked to. That includes things like:

  • Infographics
  • White papers
  • Downloadable guides and information packs
  • Videos

#3 Anchor text

The last tip for improving the relevance of your links is to optimize the anchor text. When you see the clickable text hyperlinked on a web page, usually in blue and underlined, that is the anchor text. The general purpose of anchor text is to provide some context for what page is being linked to.

For example, let’s say the link to a page on another site that has a recipe for potato leek soup. A good example of anchor text being optimized for relevance is to have it be “potato leek soup recipe”. That is the text you want to hyperlink to the recipe page.

An example of poorly optimized anchor text is to mention the soup recipe elsewhere in the sentence, and have the anchor text be “click here”. The problem with anchor text like that is that it does not give any hint or indication what it is linking to.

The issue is that search engines like Google use anchor text as a signal for relevance. The mindset is that when someone links to something natural, they are likely to describe the page in the anchor text. It is just a natural behavior.

So when you reach out to a site for a link, whether it’s a guest post or something else, make sure you ask for specific anchor text. Here are some tips for optimizing the anchor text in your links:

  • Describe the page being linked to as concisely as possible
  • Use some keywords that are relevant to your page but don’t over-stuff it
  • Mix up the keywords used in the anchor text of your backlink profile so you have a diverse mix

That last two points are important. If you use the same anchor text for all of the links you get, Google may treat it as spam and penalize you. Just remember to focus on being relevant and descriptive, and you will find natural variants for the keywords you want to target.


Search engines like Google have been shifting the focus of their algorithms to relevancy for years, and show no signs of stopping. This is especially true for link building, which has been a foundational pillar for search engine optimization for a long time.

When you’re building links, it is important to shift your focus to match Google’s for your campaign to be successful. That means targeting websites in the same niche as yours, writing high-quality content relevant to your business, and optimizing anchor text.

Whether you want to improve your organic rankings, or improve your local SEO through local link building, relevance is the new path to success.
