In this step-by-step guide, I’ll walk you through exactly how to conduct a backlink audit like a pro. Whether you’re cleaning up after an SEO agency’s shady work, taking over a new domain, or just maintaining a squeaky-clean link profile, you’ll get practical, no-fluff advice based on real-world experience. From identifying toxic links to benchmarking against competitors, we’ll cover it all with the best tools and tips for 2025.
What is a backlink Audit and why it matters
Let’s get real: if you're not auditing your backlink profile regularly, you're basically flying blind in SEO. A backlink audit is the process of examining all the websites linking back to yours to determine their quality, relevance, and impact on your search rankings.
Google has made it crystal clear that links pointing to your site can either boost you to the top, or drag you straight down. That’s why understanding how your backlink profile is built, maintained, and perceived by search engines is absolutely essential.
A good backlink can work like a five-star review from a trusted expert in your industry. A bad one? More like a shady recommendation from someone in a trench coat on a dark alley. Not exactly what you want attached to your brand.
6 steps on doing a backlink audit
Before diving into the actual analysis, the first step is to gather all your backlinks—and the best way to do that is with a tool that offers deep coverage and intuitive reporting. In this case, we’ll focus on Ahrefs, one of the most trusted tools in the SEO world for backlink analysis.
Step 1: Collect all your backlink data
This step-by-step guide will walk you through how to perform a thorough backlink audit. You'll learn how to identify toxic links, evaluate your backlink profile, and take action to strengthen your website’s authority. Whether you're cleaning up after past SEO mistakes or optimizing for future growth, this guide will show you exactly what to do.
Why Ahrefs?
Ahrefs has one of the largest and most updated backlink indexes in the world. It’s constantly crawling the web, which means it can uncover more links—especially fresh ones—than many other platforms. It also provides rich metadata for each backlink, which is essential for a thorough audit.

Step 2: Identify toxic or low-quality backlinks
Now comes the real detective work, the heart of your backlink audit. While backlinks are essential for building domain authority and boosting your rankings, not all links are created equal. In fact, some can do more harm than good. These harmful links are known as toxic backlinks, and they can seriously sabotage your SEO efforts by signaling to search engines that your site may be involved in spammy or manipulative practices.
Why they're dangerous
Google’s Penguin algorithm (now part of the core algorithm) was designed to detect and penalize link manipulation. A few bad links won’t tank your site overnight, but a pattern of unnatural links will trigger algorithmic devaluation or manual penalties.
In other words: if you're building great content and backlinks, but also dragging along a boatload of spammy links, you’re still losing the SEO game.
What are toxic backlinks?
Toxic backlinks are links that Google sees as manipulative, irrelevant, or coming from untrustworthy sources. Rather than boosting your SEO, they raise red flags and can result in ranking drops, penalties, or even complete deindexing in extreme cases.
Here are common types of toxic backlinks:
Spammy or irrelevant domains
Think foreign-language sites, spun content blogs, or pages stuffed with ads and affiliate links unrelated to your niche.
Manipulative anchor text
Over-optimized keyword stuffing like "buy cheap nike shoes" or "best casino deals online" raises suspicion fast.
Link farms or PBNs
These are artificial networks built solely to manipulate link signals. Google is great at spotting them.
Adult, gambling, or hacking sites
Even one backlink from these domains can taint your entire backlink profile.
How to identify toxic backlinks
Step 3: Evaluate link relevance, anchor text, and authority
Now that you’ve filtered out the most obviously toxic backlinks, it’s time to shift gears and take a deeper, more strategic look at what remains. This step is where your real SEO instincts come into play, because it’s not just about checking boxes or removing spam. It’s about understanding the quality and impact of the links that are still pointing to your site.
Not all remaining backlinks are necessarily good, and some may be doing more harm than you realize, not because they’re spammy, but because they’re irrelevant, overly optimized, or from weak sources. Poor-quality links can still weigh down your SEO performance by signaling inconsistency or manipulation to search engines.
How to evaluate link relevance
Check if the linking website and content are topically related to your niche or industry. A relevant backlink should come from a page that naturally connects to your site’s subject matter, ideally discussing similar themes, audiences, or keywords.
Step 1
Open the backlink report you exported from Ahrefs or your SEO tool of choice. Locate the columns showing the referring page URL and page title.
Step 2
Manually review a representative sample of backlinks by visiting those URLs in your browser. Your goal is to judge how topically aligned each linking page is with your own content. Ask yourself: Does this page belong in the same industry or niche as my site?
Step 3
In your spreadsheet, add a column titled “Relevance” and assign one of three values to each backlink:
-
High Relevance – closely related to your topic or niche.
-
Medium Relevance – loosely related but still contextual.
-
Low Relevance – completely unrelated or random.
How to audit anchor text
Anchor text is one of the most powerful signals for search engines, but when overused or poorly distributed, it can also trigger penalties.
Step 1
Sort your spreadsheet by the anchor text column to easily spot repetition and patterns.
Step 2
Identify and label anchor text into functional categories:
| Anchor Text Example | Anchor Type |
| YourBrand | Branded |
| Naked URL | |
| complete backlink audit guide | Exact Match |
| best SEO tips | Partial Match |
| click here | Generic |
Step 3
Count the frequency of each type. You can use a pivot table or basic counts to calculate percentages.
If your profile consists of 60–70% exact-match anchors, this is a red flag. Google expects anchor text diversity. Ideally, branded anchors should make up the largest share, followed by a healthy mix of naked, partial match, and generic anchors.
Create a summary table like this:
| Anchor Type | Count | Percentage |
| Branded | 120 | 40% |
| Exact Match | 90 | 30% |
| Partial Match | 45 | 15% |
| Generic | 30 | 10% |
| Naked URL | 15 | 5% |
How to measure domain authority and trust
High authority domains lend more SEO power to your site, but only if they’re also relevant and trustworthy.
Step 1
In your spreadsheet, refer to the Domain Rating (DR) from Ahrefs or Domain Authority (DA) from Moz.
Step 2
Add a new column labeled “Authority Score” and categorize domains as follows:
| Authority Range | Classification |
| DR 70+ | High Authority |
| DR 40–69 | Medium Authority |
| DR < 40 | Low Authority |
But don’t stop there. Manually inspect a few high-DR links. If a DR 85 site is linking to you from a footer stuffed with 100 outbound links, or from irrelevant or low-quality content, it could be doing more harm than good. Authority without context is meaningless.
Step 3
Create a composite quality rating by combining relevance, anchor text diversity, and authority into a final score for each backlink:
| Referring Domain | Relevance | Anchor Type | Authority | Final Rating |
| digitaltools.com | High | Branded | 78 | Excellent |
| blognews.ru | Low | Exact Match | 19 | Risky |
| healthyfit.net | Medium | Partial Match | 45 | Good |
This makes it easier to sort and prioritize your backlinks for outreach, or reinforcement.
Step 4: Remove Harmful Backlinks
At this point, you’ve identified the backlinks that pose a risk to your site’s SEO, whether due to spam, irrelevance, or association with link farms and other low-quality sources. Now it’s time to take decisive action and clean them up. You have two legitimate approaches: removal requests. Each has its place in a thorough backlink audit.
Requesting Link Removal (Manual and Strategic)
Removing a harmful link at the source is always the preferred method. If you can get the site owner to physically delete the link from their page, that’s one less toxic association to worry about, without involving Google.
When to Use This Approach
-
The link is clearly harmful (e.g., from an adult site or link farm).
-
The website is still active and maintained.
-
The linking domain has relatively decent authority, but the link is placed in a spammy context (e.g., footer, sidebar, comment section).
Step 1: Identify the linking site and locate contact details.
Before you can ask for a backlink to be removed, you need to figure out who to contact. Start by identifying the linking site and searching for their contact information. Use tools like Whois Lookup to find the domain’s registrant email this can be especially useful for smaller or anonymous websites. For more precise contact details, try Hunter.io to pull email addresses directly from the site. If those fail, check the site’s contact page, about section, or even social media profiles. Many site owners are reachable via LinkedIn, Twitter, or even a contact form on the site.
Taking a few extra minutes to locate the right contact ensures your request doesn’t get ignored or end up in the wrong inbox.
Step 2: Write a polite, concise removal request
Once you’ve found a way to contact the site owner, craft a professional and respectful message. Keep it short and to the point, avoid sounding accusatory or threatening, even if the link seems spammy. Most site owners are more willing to help if you remain courteous. Use a clear subject line like "Link Removal Request for [YourDomain.com]", and include the exact URL where the link appears and the URL it’s pointing to on your site. Explain that you're performing a backlink audit and that the link is no longer relevant.
A polite tone and clear request go a long way. Site owners are more likely to help if you approach them as a professional, not an adversary.
Step 3: Track your outreach
Managing your link removal requests is just as important as sending them. Use your backlink audit spreadsheet to track your outreach efforts. Create simple columns like “Contacted,” “Response Received,” “Link Removed,” and “Date.” This helps you monitor your progress and avoid following up too often or missing replies. Be prepared, many site owners won’t respond or may ignore your message. That’s perfectly normal.
If you don’t get a reply after a couple of weeks, don’t worry. That’s when it’s time to escalate the process by preparing a disavow file for Google.
Step 5: Benchmark your link profile against competitors
A backlink audit in isolation is just one side of the equation. To truly understand where your site stands, you need to evaluate your backlink profile in relation to your top-ranking competitors. This comparison adds crucial context, helping you not only identify your strengths and weaknesses but also uncover valuable link-building opportunities.
Benchmarking is not about copying someone else’s strategy it’s about analyzing patterns, spotting missed opportunities, and closing the gaps that keep your site from ranking higher.
Why competitive benchmarking matters
Search engines don’t rank websites in a vacuum. Your site is evaluated in relation to others targeting the same keywords. If your competitors have more high-quality backlinks from authoritative, niche-relevant domains, and your link profile is thinner or less relevant, guess who’s going to outrank whom?
By comparing your site to those that currently dominate the SERPs, you gain clarity on:
- What a "competitive" backlink profile looks like in your niche.
- Which specific sites and industries are willing to link to content like yours.
- Where your profile falls short—whether in quantity, quality, diversity, or relevance.

Step 6: Monitor and maintain a healthy backlink profile
Backlink audits are not a one-and-done task, they're part of a continuous SEO health routine. Once you've cleaned up your profile, removed toxic links, and benchmarked against competitors, the real challenge begins: keeping it clean.
Links are constantly changing. You may gain links from reputable sources, but you might also acquire spammy backlinks without your knowledge, or lose key links without realizing it. That’s why ongoing backlink monitoring is essential. It's not just maintenance, it's insurance for your SEO efforts.
Why ongoing monitoring matters
Here’s what happens if you don’t monitor your backlink profile:
- You may become the target of a negative SEO campaign, where spammy links are intentionally pointed at your site.
- You could lose links from high-authority domains without warning, which can impact rankings.
- You might accumulate poor-quality links over time, triggering a slow decline in visibility that’s hard to diagnose later.
Regular monitoring helps you detect threats early, fix problems fast, and ensure you’re consistently building a trustworthy digital footprint.
How to Monitor Your Backlink Profile
1. Set up automated Alerts
Most top-tier SEO tools offer automated monitoring features. Here's how to use them effectively:
Ahrefs:
- Go to “Alerts” in your dashboard.
- Set up a New Backlinks Alert for your domain.
- Choose the frequency (daily or weekly), and enter your email.
- You'll get notified every time a new backlink appears, or when you lose an existing one.
Google Search Console:
- Navigate to the “Links” section under your domain property.
- Regularly check the “Top linking sites” and “Top linked pages” sections.
- GSC also sends alerts for manual actions or security issues related to backlinks.
This real-time visibility means you’re never caught off guard.
2. Track link losses and new link quality
Monitoring isn’t just about volume, it’s about value. Not all new links are good, and not all lost links are bad.
To stay proactive:
- Log new backlinks in a dedicated tab in your audit spreadsheet.
- Review each one for relevance, anchor text, and authority, just like you did during the audit.
- If a high-authority or relevant link disappears, investigate. Did the page get deleted? Is it a temporary drop? Can you reclaim it?
Use Ahrefs’ “Lost Backlinks” and “New Backlinks” reports weekly to catch these changes early.
3. Perform regular mini-audits
Instead of waiting for rankings to drop before taking action, schedule regular mini-audits:
| Frequency | Action |
| Weekly | Review new/lost backlinks and flag spam |
| Monthly | Spot-check anchor text trends and referring domains |
| Quarterly | Run full toxic link scan + refresh disavow list |
| Bi-annually | Benchmark against competitors |
Create calendar reminders or integrate this into your SEO reporting cycle. Consistency beats crisis.
4. Proactive link health strategies
A healthy backlink profile doesn’t just happen, it’s the result of proactive link building and defensive maintenance. Here are some ongoing best practices:
- Reclaim broken or lost backlinks by contacting site owners or using tools like Ahrefs’ “Broken Backlinks.”
- Disavow suspicious links regularly, especially after a negative SEO attack or content scraping.
- Build link equity intentionally through quality guest posting, digital PR, or unlinked brand mention outreach.
Avoid shady link schemes, even if they promise quick wins. It’s not worth the long-term risk.
Bonus Tips: tactics to improve link quality
Once your backlink audit is complete and your profile is clean, your next goal is to improve link quality moving forward. Just like in personal health, maintenance and prevention will save you from painful clean-ups in the future. The best SEO strategies aren’t just reactive, they’re proactive. Here’s how to build links that not only look good but also move the needle in rankings and authority.
1. Create content that deserves links
The foundation of high-quality backlinks is high-quality content. If your pages don’t offer genuine value, relevance, or uniqueness, no one will want to link to them—and those who do might not be the kind of sites you want in your profile.
How to implement it:
-
Original Research: Publish surveys, industry statistics, or case studies. Data-driven content attracts journalists, bloggers, and researchers.
-
In-Depth Guides: Create ultimate resources that cover a topic comprehensively. These tend to attract organic links from listicles, roundups, and other bloggers.
-
Infographics and Visuals: Design data visualizations, process diagrams, or comparison charts that others would find useful to embed (and credit).
Example: Instead of writing “5 Tips for SEO,” create a 4,000-word guide titled “The Complete 2025 SEO Blueprint” with expert insights, original interviews, and downloadable templates.
2. Reclaim lost or broken backlinks
Many websites link to your content over time, but due to redesigns, domain changes, or content removals, those links may break or vanish. You can often reclaim them—especially if the intent to link was already there.
How to implement it:
- Use Ahrefs' Broken Backlinks report: Go to Site Explorer → Your Domain → Backlinks → Filter by "Broken."
- Use Google Search Console to identify 404 errors under Coverage.
- Check for unlinked brand mentions using tools like Mention or Brand24—these are cases where someone mentioned your brand but forgot to add a link.
Reach out to the site owner with a short email like:
"Hi [Name], I noticed you mentioned [Your Brand] in your article. Would you mind linking to our original source at [URL]? It would help readers find more context. Thanks!"
This is low-effort, high-reward outreach, they’ve already shown interest in your content.
3. Guest post selectively on authoritative, relevant sites
Guest posting is still one of the most effective white-hat link building methods, when done right. The key is selectivity. You don’t want links from content farms, low-quality blogs, or irrelevant websites. Your goal is to write for high-authority sites that share your audience and industry.
How to implement it:
-
Identify target websites using tools like BuzzSumo
-
Use Ahrefs to check their DR and the backlink profile of the content they publish.
-
Pitch content ideas that are fresh, insightful, and directly useful to their readers. Don’t offer generic SEO content, customize every pitch.
Example Pitch:
"Hi [Editor Name], I’m [Your Name], and I recently published a piece on [Topic] that got great feedback. I’d love to write something tailored for [Their Site], perhaps on [Specific Angle]? Let me know if you're open to a collaboration!"
Focus on building relationships, not just dropping a link.
4. Use HARO to earn editorial mentions
HARO (Help A Reporter Out) connects journalists with expert sources. If you respond to a relevant query with a useful quote or insight, you can land backlinks from major media outlets, including Forbes, Business Insider, and HubSpot.
How to implement it:
- Sign up at https://www.helpareporter.com/
- Choose “Source” and select your preferred industries.
- Monitor daily emails for journalist queries (they send 3 per day).
- Respond quickly and succinctly. Journalists often quote the first high-quality response they get.
Pro tip: Keep a response template ready, but personalize every pitch. Include a quick intro, your quote, and a short bio with your name, role, and website link.
Over time, this builds editorial credibility and gives you powerful, organic backlinks from high-authority domains.
5. Track competitor links and go after the same sources
Your competitors are constantly earning new backlinks. If a site linked to them, there's a good chance they'll link to you too, especially if you offer better content, updated insights, or a fresh perspective.
How to implement it:
-
In Ahrefs, go to Site Explorer → Enter competitor domain → Backlinks → Filter by “New” (past 30 days).
-
Use Link Intersect Tool to find sites that link to 2–3 of your competitors but not to you.
-
Make a list of these linking domains, analyze the context (guest post, roundup, resource page), and plan outreach.
Approach tips:
-
If the link is from a roundup post (“Top Tools for X”), pitch your tool as an alternative or update.
-
If it's from a guest post, see if you can offer a related article.
-
If it's from a broken link, offer your own content as a replacement.
This strategy is about targeting warm prospects—people already open to linking to content in your space.
6. Launch a digital PR campaign around a data-driven story
Digital PR combines traditional PR tactics with SEO goals, focusing on creating stories or assets that earn high-authority links through media coverage. A well-executed digital PR campaign can land you backlinks from top-tier publications that are otherwise hard to access.
How to implement it:
- Find a newsworthy hook: Use your internal data, conduct a small survey, or analyze industry trends to uncover insights that journalists would find compelling.
- Package it well: Create a polished landing page with visuals (charts, graphs, or infographics) and clear takeaways. Include expert commentary or predictions to give it more authority.
- Pitch it to journalists: Build a list of journalists or editors in your niche using tools like Muck Rack or Twitter search. Personalize each pitch by referencing past stories they’ve covered.
Example: If you run an e-commerce platform, create a report like “The Most Returned Products by Category in 2025” using your internal data. Include graphics and expert insights about consumer behavior, then pitch it to retail or business publications.
Common backlink audit mistakes to avoid
Even experienced SEO professionals can fall into traps when auditing backlinks. A single misstep can result in wasted effort or worse, damage to your rankings. To help you avoid these pitfalls, here are the most common mistakes to watch out for during a backlink audit:
1. Focusing Only on Quantity, Not Quality
Many people obsess over having more backlinks than competitors. But link-building today is about link quality, not raw numbers.
Avoid it by:
Prioritize links from high-authority, relevant domains over dozens of low-value ones. A single editorial backlink from a DR 70 site in your niche can outweigh hundreds of weak ones.
2. Ignoring nofollow links completely
While nofollow links don’t pass PageRank directly, they can still drive traffic, build brand awareness, and support a natural link profile.
Avoid it by:
Don’t automatically discard nofollow links as “worthless.” Analyze their context and source. A nofollow link from a high-profile news outlet is still valuable.
3. Not checking link context
Some backlinks may appear valuable on paper but when you look at the page, you find your link buried in a spammy footer or surrounded by unrelated content.
Avoid it by:
Always check the placement and surrounding content of a backlink. Links embedded naturally in editorial content are significantly more valuable.
4. Failing to audit regularly
Doing a backlink audit once a year (or only when something goes wrong) puts you in a reactive position. By then, damage may already be done.
Avoid it by:
Build regular backlink reviews into your SEO workflow. Set calendar reminders for monthly check-ins and biannual full audits.
5. Using only one tool
No SEO tool has a complete picture of the web. Limiting yourself to just one data source could mean missing hundreds, or thousands, of backlinks.
Avoid it by:
Use at least two tools (e.g., Ahrefs + Google Search Console) when collecting and cross-referencing your backlink data. You'll get broader coverage and more accurate insights.
6. Overlooking internal links
While this guide focuses on external backlinks, ignoring internal linking is another mistake. Poor internal linking can weaken your site’s structure and dilute link equity.
Avoid it by:
Audit your internal links periodically to ensure strategic pages are properly supported and that orphan pages are connected.
Final thoughts: Backlink audits as an ongoing strategy
Backlink audits aren’t just a checklist item on your quarterly SEO plan they’re a foundational habit of any serious website owner, marketer, or SEO professional. The web is constantly evolving. What helps you rank today may be obsolete or even harmful six months from now. That’s why maintaining a clean, powerful, and trustworthy backlink profile is not a one-time activity. It’s an ongoing process that requires discipline, insight, and action.
When done consistently, backlink audits do far more than clean up spam. They protect your site’s authority by ensuring you're not unknowingly penalized by toxic links. They enhance your rankings by identifying and reinforcing your most valuable link sources. And perhaps most importantly, they reveal new opportunities, fresh link prospects, gaps in your strategy, and competitive advantages you can act on immediately.
SEO in 2025 is more competitive and nuanced than ever. Search engines are smarter, spam tactics are sneakier, and quality is the new currency. In this environment, backlinks remain one of the most powerful ranking factors but only when they’re earned, monitored, and managed properly. Treating backlinks like a static asset is a mistake. Instead, treat them like what they are: a living, breathing part of your online reputation.
