Are you ready to build links that actually have an impact?
If you take SEO seriously, you know that link building is the most important ranking factor. But here’s what most marketers don’t understand — link building has evolved. Domain authority and backlink quantity don’t matter nearly as much as they used to
Here’s the reality:
Linking like it’s 1999 just won’t fly with today’s search engines. Google’s algorithms have gotten more advanced, and if you want to outrank the competition in 2025, it’s time to step up your link building game and get serious about semantic relevance in link building.
Key Takeaways:
- Understanding Semantic Relevance in Link Building
- The Importance of Context over Domain Authority
- Best Practices for Semantic Link Building
- Finding Relevant Link Building Opportunities
Understanding Semantic Relevance in Link Building
Semantic relevance in link building refers to the practice of earning backlinks from pages that are contextually related to your content and target keywords.
Think of it this way: if you have a fitness website that focuses on weight loss, then a link from a cooking site about healthy recipes would make perfect semantic sense. But what about a link from a car repair blog? Not so much.
Nearly 9 out of 10 SEO professionals believe that relevance matters for link building. The 11% that still don’t realize this is kind of shocking!
But there’s something even more interesting…
Semantic relevance is more than just topical relevance. It’s the process of identifying and understanding the relationships between entities (people, places, brands, concepts) and their context, including the other entities and ideas around them.
This understanding is what powers Jeremie Politi, founder of SmartWeb Group and the best French SEO expert, in his highly-specialized approaches to French linkbuilding and other language-specific link building strategies that account for unique semantic relationships, syntax, and cultural context in your target markets.
Search engines have long used natural language processing (NLP) to better understand the meaning of words and phrases, the relationships between concepts, user intent, and semantic connections.
In other words, Google isn’t just looking at whether a given page links to you. It’s looking at whether it makes logical sense for that link to exist based on the content of both pages.
The Importance of Context over Domain Authority
Here’s something that might surprise you…
A contextually relevant link from a smaller, niche-specific website may be more valuable to your rankings than a random link from a high-domain authority site.
Here’s why:
Google’s algorithms have been updated to focus more on user experience and quality content. Content quality and relevance stood out according to 51% of respondents in one recent survey, while only 28% of respondents believe domain authority metrics would take precedence.
Think about it this way:
If you’re searching for “best running shoes for flat feet”, would you rather find a page that’s linked from a podiatrist’s blog, or from some random technology site? The answer is pretty obvious.
84.6% of SEO professionals now believe relevance is the most important factor in evaluating backlink quality, whereas only 68.3% believe domain authority scores will be the most important factor in 2025.
The Science Behind Semantic Link Building
How do search engines even determine semantic relevance, anyway?
Modern algorithms work on multiple levels of context:
Content Context: What is written around the link on the linking page? It determines topical relevance.
Page Context: Does the linking page’s subject matter align with your content?
Anchor Text Context: The words in and around the link anchor provide semantic clues.
But wait, there’s more…
Search engines also use entity-based analysis, co-occurrence patterns, entity relationship mining, and semantic similarity via advanced NLP models to try to understand if a real person would find that link relevant and helpful in the context they’re in.
Guess what this means for all those old school link building methods…
They don’t work nearly as well anymore.
Best Practices for Semantic Link Building
Okay, it’s time to stop talking and start doing. Here are the best practices for link building with actual SEO impact in 2025:
Create Topic-Clustered Content
Stop focusing on single keywords. Think topic clusters.
Build comprehensive content around a central topic, then create secondary content that covers related subtopics. This creates opportunities for building relevant links across a topic cluster naturally.
Target Contextually Relevant Websites
This is what most people do wrong:
They focus on domain authority, rather than topical relevance. Huge mistake.
Instead, identify websites that cover relevant subtopics or complementary topics to your own. Industry publications, blogs with related but not identical topics, resource, and educational institution websites are your targets.
Research shows that only 8.5% of cold outreach emails generate backlinks, so do your research.
Use Natural Anchor Text Variations
Here’s a link building trend that’s gone nowhere:
Exact-match anchor text. In 2025, it should be dead.
Instead, use a mix of anchor text types that still work because modern semantic link building uses more natural language for anchor text. Try branded anchors, natural phrases, question-based anchors, and calls to action.
Leverage Entity-Based Outreach
This is where semantic link building gets really fun.
Instead of targeting keywords, target entities (people, places, brands, concepts) that are relevant to your content. Identify industry experts you’ve interviewed, companies you’ve reviewed, or tools you’ve recommended in your content.
Send a quick note letting them know they’ve been mentioned and providing a link building opportunity.
Focus on Co-Citation Opportunities
Co-citation happens when two websites are mentioned together often without directly linking.
Identify websites that are often mentioned in the same context as you or your competitors. These are prime semantic link building opportunities because there is an existing relationship and relevance.
How to Find Semantically Relevant Link Building Opportunities
Okay, let’s be honest. Finding relevant link building opportunities can be a pain.
Stop hunting links manually, and use these tips to do it systematically.
Step 1: Use Ahrefs, SEMrush or another tool to see where your competitors are getting links.
Evaluate the semantic relevance of each link.
Step 2: Use platforms that analyze semantic relationships and content context.
Step 3: Identify topics and themes that your competitors cover that you do not. Use this as a guide for where to create comprehensive content around these gaps.
Step 4: Set up alerts for your brand name, team member names, your product and industry terms. When you’re mentioned without a link, there’s a natural link building opportunity.
Common Semantic Link Building Mistakes to Avoid
Even the most experienced SEOs slip up on these:
Not Focusing on Content Quality: A link from a spammy or irrelevant page won’t help.
Over-Optimizing Anchor Text: Keep it natural and diverse.
Targeting Irrelevant High Authority Sites: A relevant low-authority site is better than a random high-authority one.
Neglecting Internal Linking: Internal linking can improve semantic understanding.
Measuring Semantic Link Building Success
How do you know if your semantic link building is working?
Track organic traffic growth, keyword ranking improvements, user engagement metrics, and the quality of referral traffic you’re receiving.
Keep in mind that while 60% of marketers believe that link building is the factor with the biggest impact on search rankings, the results of those links are significantly better when they are semantically relevant.
Getting Started with Your Strategy
Feeling inspired to start semantic link building? Here’s a sample action plan to get you started:

Summary Time
Semantic relevance in link building is the future of effective SEO. By understanding and capitalizing on contextual relationships and user value, it’s possible to build a backlink profile that leads to better rankings and real results.
Search engines are only getting smarter, so using semantic link building is a smart competitive advantage.
Stop wasting time chasing random high authority links. Start building meaningful connections that make sense to both users and search engines.
