what is semrush subdomain backlinks?

Let’s face it: SEO can feel like trying to win a staring contest with Google’s algorithm — except Google never blinks. If you’ve ever wondered, “What is Semrush subdomain backlinks?” while sipping your third coffee and pretending to understand your site’s analytics, you’re in good company. Today, we’re breaking down this not-so-mysterious topic, sharing why it matters, and how we at bloggingmachine.io can help you turn those backlinks into real business growth (without needing a PhD in SEO).

Semrush Subdomain Backlinks: The Basics (No Buzzwords, Promise)

First, let’s decode the jargon. Semrush is a heavyweight in the SEO ring, known for its massive, ever-growing backlink database. As of 2025, Semrush tracks a mind-boggling 43 trillion backlinks from 390 million referring domains — and yes, that’s trillion with a “T.” It crawls 10 billion URLs daily to keep its data fresher than your morning bagel.

But what about subdomain backlinks? Imagine your website is a hotel. The main domain (example.com) is the lobby, while subdomains (like blog.example.com or shop.example.com) are the themed suites. Subdomain backlinks are links from other sites that point specifically to those suites, not just the lobby. Semrush lets you analyze these links at the subdomain level, so you know exactly which “rooms” are the most popular.

Why Should You Care About Subdomain Backlinks?

Let’s be honest: not all parts of your website are created equal. Your blog might be a content superstar, while your support portal is more like that mysterious storage closet everyone avoids. Here’s why subdomain backlinks deserve your attention:

Granular Insights: Subdomains often serve different purposes — blogs, shops, support centers. Analyzing backlinks at this level shows you which sections are pulling their weight.
Content Strategy Goldmine: Find out what’s working (and what’s not) so you can double down on the good stuff.
SEO Health Check: Spot negative SEO attacks or spammy links targeting specific subdomains before they become a problem.

As one SEO expert put it:

“The key to any backlink analysis tool is data. And Semrush has the most data of any online SEO tool in the world. This makes it one of the best SEO tools for website owners, SEO services, and link-building services.”

How to Leverage Subdomain Backlinks Like a Pro

So, you know what is Semrush subdomain backlinks, but how do you actually use this knowledge without falling asleep at your desk? Here’s the playbook:

1. Segment Analysis

Don’t just look at your domain as a whole — analyze backlinks at the subdomain level. This helps you see which sections are attracting the most authority and why. Maybe your blog is the real MVP, or perhaps your shop is quietly racking up links from industry forums.

2. Content Strategy

Identify subdomains with strong backlink profiles. What kind of content lives there? Replicate those strategies across other site areas. If your “How-To” guides are backlink magnets, maybe it’s time for a few more.

3. Targeted Link Building

Focus your outreach and guest posting efforts on subdomains that align with your business goals or have the most growth potential. Don’t waste time pitching your support portal if your blog is where the action is.

4. Disavow Harmful Links

Use Semrush to spot and disavow toxic backlinks that could be dragging down your subdomain rankings. It’s like spring cleaning, but for your SEO.

5. Competitor Benchmarking

Compare your subdomain backlink profiles with competitors. Spot gaps, find opportunities, and — let’s be honest — enjoy a little schadenfreude when you’re ahead.
