As a business owner, you should know that not all backlinks help your website rank. Some work against you and can drag down rankings you’ve spent months trying to build. These are usually spammy or low-quality links, and they’re hard to spot without digging into your link profile.
Fortunately, you can find these problems with a backlink audit. But many business owners don’t know where to start looking or what actually makes a link harmful.
In this guide, we’ll show you what to check and how to identify risky backlinks based on our experience reviewing link profiles at https://www.intelligentlinks.com.au.
Before looking at how to run one, let’s see what a backlink audit involves.
What Is a Backlink Audit?
A backlink audit is a review of every link pointing to your website. It looks at where the links come from and whether they’re helping or hurting your SEO. The audit then sorts your backlinks into categories such as healthy, low-value, and toxic. From there, you know exactly where your profile stands and what needs attention.
Why Link Quality Outweighs Quantity
Link quality outweighs quantity because Google cares more about where a link comes from than how many you’ve collected. A single link from a respected industry site can carry more weight than fifty links from low-quality directories.
Say two bakeries both have 100 backlinks. One earned links from local food blogs and news sites. The other bought links from unrelated, spammy sites just to boost the count. Google rewards the first bakery and may penalise the second, even though the numbers look identical on paper.
Signs Your Website Has a Backlink Problem
Not sure if your backlink profile needs a closer look? Here are some signs worth watching for:
- Sudden Drop in Organic Traffic: Unexplained traffic declines can sometimes point to backlink issues, especially if your content and site structure haven’t changed.
- Links From Irrelevant or Suspicious Domains: If a large number of your referring domains have nothing to do with your industry, or look like link farms, that’s a red flag. These are the kinds of domains that trigger link spam flags in Google’s systems.
- A Spike in Referring Domains Overnight: A sudden jump in domains linking to you sounds good, but it rarely is. It can signal a negative SEO attack where someone points low-quality links at your site to hurt your rankings.
- Manual Action in Google Search Console: This one is hard to miss. Google will notify you directly if your site has been penalised for unnatural links, but by that point, the damage to your organic traffic is already done.
Running a backlink audit helps you catch these issues early. But identifying a problem is only part of the process. You also need to know what makes a link helpful, suspicious, or potentially harmful.
What a Backlink Audit Should Cover
As we said, the goal of a backlink audit is to find out whether your links are helping or hurting your search performance. To do that, most audits look at these four areas:
- Referring Domains: These are the unique websites linking to yours. Reviewing them helps you understand if your backlinks come from credible, relevant sources or from sites that may be hurting your profile.
- Anchor Text Distribution: Search engines look at the clickable text used in links pointing to your site. When too many links share the exact same keyword-heavy anchor text, Google can interpret it as manipulation and suppress your rankings across multiple pages.
- Lost or Broken Links: When a credible site that once linked to you removes or breaks that link, you lose a ranking signal that was working in your favour. If that happens, try to recover the link rather than replace it with a new one.
- Toxic or Spammy Links: This is where an audit looks for links you probably wouldn’t want associated with your brand. Sources such as link farms and private blog networks can signal manipulative link-building practices and may need to be removed.
Across the profiles we’ve reviewed, these four areas surface the most damaging issues. Catching them early means less recovery work and fewer ranking setbacks down the line.
DIY vs. Hiring a Professional
Both approaches can help you identify backlink issues, but they differ in cost, depth, and the amount of work involved. The table below compares the two options side by side.
| Factor | DIY Audit | Professional Audit |
| Best for | Small websites with relatively few backlinks | Large sites or complex backlink profiles |
| Tools used | Google Search Console and other free tools | Ahrefs, Semrush, and other advanced tools |
| Time required | You handle the review yourself | Most of the work is handled for you |
| Link analysis | Good for spotting obvious issues | Better for uncovering patterns and hidden risks |
| Manual penalties | Can be difficult to investigate | Usually part of the audit process |
| Cost | Free or low cost | Paid service |
If you’re not sure where you stand, starting with Google Search Console is a reasonable first step. Once the data starts revealing patterns you can’t explain or fix on your own, that’s usually the signal to bring in a professional.
How to Act on Your Results
At this stage, your audit is finished. Next, it’s time to act on what you’ve found. Follow these steps:
- Separate Your Backlinks Into Three Groups: Go through your backlink data and classify each one as healthy, suspicious, or harmful. This makes it easier to see which ones support your SEO, need monitoring, or require action.
- Disavow Toxic Links Carefully: Disavowing tells Google to ignore specific links pointing to your site. You can do this through Google’s Disavow Tool. However, review each one carefully first, since removing legitimate links can take away signals that are helping your rankings.
- Fix or Recover Broken Links: If a credible site that once linked to you now shows a broken URL, reach out and request the link be restored. These are easier to recover than building new ones and can give your keyword rankings a quick lift.
- Monitor Your Profile Going Forward: A backlink audit isn’t a one-time task. Set a reminder to check your profile every few months so new spam links don’t go unnoticed, and your search rankings stay on track.
Rankings can take a few weeks to reflect the changes, so treat these steps as ongoing maintenance rather than a single fix.

Frequently Asked Questions
Backlink audits raise a lot of questions, especially if it’s your first time running one. The answers below cover what most business owners want to know.
How many referring domains do I actually need to rank well?
There’s no universal number. The quality and relevance of those domains are far more important than how many you have. Ten links from authoritative, industry-relevant sites will do more for your rankings than a hundred from unrelated or low-quality ones.
Can a backlink audit directly improve my organic search traffic?
Not directly. An audit identifies problems, but the improvements come from what you do afterwards. Removing harmful links, fixing lost opportunities, and improving your backlink profile can help remove obstacles that may be limiting your rankings.
What is domain authority and does it affect my backlink audit?
Domain authority is a score created by SEO tools to estimate a website’s ranking strength based on factors like its backlink profile. It isn’t a Google ranking factor, but it can help you compare referring domains during a backlink audit.
Does link building affect AI visibility and AI search results?
Yes, it can play a role. AI search systems often rely on trusted sources, and a strong backlink profile can support your site’s credibility. While backlinks don’t guarantee visibility in AI-generated answers, links from reputable sites can improve your chances of being recognised as a reliable resource.
How long does a backlink audit take?
A basic DIY audit using Google Search Console can take a few hours. A thorough professional audit typically takes a few days, depending on the size of your backlink profile and how many areas need reviewing.
