Few topics in SEO cause as much anxiety as backlinks. Website owners routinely open their analytics tools, see dozens of links from websites with low domain authority (DA), and immediately wonder whether those links are dragging their rankings down. The short answer is that low DA backlinks rarely hurt your SEO on their own, and many of them actually help. The longer answer depends on relevance, intent, patterns, and the overall health of your link profile. In this article, we break down what domain authority really measures, how search engines evaluate links, and how to decide which low authority links are worth keeping.

What Domain Authority Actually Measures
Domain authority is a third party metric created by Moz to estimate how likely a website is to rank in search results. Similar metrics include Domain Rating from Ahrefs and Authority Score from Semrush. It is important to understand that none of these metrics are used by Google. They are predictive scores built on each tool's own link index, designed to help marketers compare websites quickly.
Because DA is a logarithmic, relative score, most websites on the internet naturally sit at the lower end of the scale. A brand new local bakery blog, a niche hobby forum, or a small industry association website might have a DA under 20 while still being completely legitimate, well maintained, and relevant. Treating every low DA website as a threat would mean rejecting a huge portion of the real web.
How Google Evaluates Backlinks
Google looks at links through the lens of relevance, trust, and naturalness. Its algorithms consider whether the linking page is topically related to yours, whether the link sits within useful editorial content, whether the anchor text looks natural, and whether the link appears to be part of a manipulative scheme. Google has repeatedly stated that its systems are very good at ignoring spammy or low value links rather than penalizing the website that receives them.
This means a link from a small but relevant website can pass meaningful value, especially when it sends real visitors. Meanwhile, a link from a high DA website that has nothing to do with your industry may pass very little benefit at all. Authority matters, but relevance and context often matter more.
When Low Domain Authority Backlinks Help Your SEO
Low authority links are often a sign of a natural backlink profile. Real businesses earn links from local news outlets, suppliers, customers, community groups, small bloggers, and niche directories. A profile that contains only high DA links can actually look suspicious because it does not reflect how links are earned organically.
Low DA links also help in several practical ways:
- Topical relevance: A niche website discussing your exact subject sends strong contextual signals.
- Referral traffic: Engaged communities can send visitors who convert, regardless of the website's score.
- Local signals: Local business associations and community websites support local search visibility.
- Future growth: Many small websites grow over time, and a link earned early can gain value later.
- Diversity: A wide range of referring domains contributes to a balanced, trustworthy profile.
When Low Quality Backlinks Can Hurt
The real problem is not low authority. It is low quality and manipulation. Links can become a concern when they come from private blog networks, link farms, hacked websites, automatically generated spam pages, or websites created solely to sell links. Large volumes of exact match anchor text, sudden spikes of irrelevant links, and links placed in footers across thousands of unrelated pages are also red flags.
If you have participated in link schemes, purchased large packages of cheap links, or been targeted by negative SEO, you may see ranking drops or receive a manual action notice in Google Search Console. In these cases, the issue is the pattern of manipulation rather than the DA number attached to each linking domain.
How to Audit Your Low Authority Backlinks
A practical backlink audit starts by exporting your links from Google Search Console and at least one third party tool. From there, review each referring domain using a simple set of questions. Is the website real, with genuine content and a purpose? Is it topically or geographically related to your business? Does the page get any organic traffic? Is the anchor text natural? Was the link placed editorially or does it look automated?
Most low DA links will pass this review easily. Links that fail on several criteria at once deserve a closer look. Group the suspicious ones together and look for patterns, such as many links from the same network or the same spammy anchor text repeated across domains.
Should You Use the Disavow Tool?
Google's disavow tool lets you ask Google to ignore specific links or domains. It is a powerful tool, but it is also easy to misuse. Google recommends using it only when you have a significant number of spammy, artificial, or low quality links pointing to your website and you believe they are causing, or are likely to cause, a manual action.
Disavowing harmless low DA links can actually remove value you were benefiting from. For most websites, the best approach is to leave ordinary low authority links alone, disavow only clear spam networks or links you knowingly built through schemes, and focus energy on earning better links going forward.
Building a Stronger Link Profile Going Forward
Rather than obsessing over individual low DA links, concentrate on the overall direction of your profile. Create genuinely useful resources such as original research, detailed guides, and tools that people want to reference. Build relationships with industry publications, partners, and local organizations. Contribute expert commentary to journalists and podcasts. Each of these tactics earns a mix of high and low authority links that collectively tell search engines your website deserves to rank.
Consistency matters more than chasing a single high profile link. Steady, natural growth in relevant referring domains is one of the strongest long term signals you can send.
Final Thoughts
Backlinks with low domain authority do not automatically hurt your SEO. In most cases they are a normal, healthy part of how the web links together, and many of them provide real relevance, traffic, and trust. The links to worry about are those that are manipulative, spammy, or part of obvious schemes. By auditing thoughtfully, disavowing sparingly, and investing in quality content and outreach, you can build a backlink profile that supports sustainable rankings for years to come.
