Most advice on improving domain authority boils down to one word, “links,” but that is only half useful without knowing which links actually move the number and which ones waste months of outreach effort. The strategies below focus on what consistently works rather than padding the list with filler tactics.
Understand What Actually Drives the Score First
Domain Authority, a 1 to 100 score developed by Moz, is driven primarily by the number and quality of unique linking root domains, not total backlink count. Ten links from ten different authoritative sites move the score far more than a hundred links from the same low-quality directory.
This single fact changes how most of the strategies below should be prioritized, since quantity-focused tactics tend to underperform compared to fewer, stronger placements.
1. Earn Links Through Original Data and Research
Publishing original data, surveys, or studies gives journalists and bloggers something concrete to cite, which generates natural backlinks without direct outreach. This approach tends to produce the highest quality links since other sites link because the content is genuinely useful, not because of a request.
From experience, a single well-promoted original study has earned more high-authority links for clients than three months of cold outreach combined, simply because data-driven content gives writers an actual reason to cite the source.
2. Fix Broken Backlinks Before Building New Ones
Reclaiming broken backlinks, links pointing to pages that have moved, changed URLs, or been deleted, recovers authority you already earned without any new outreach. This is consistently the fastest authority win available since the relationship and the link placement already exist, only the destination needs fixing.
Our Bulk Broken Link Checker finds these dead link opportunities across your site in bulk, which turns a normally tedious manual audit into a quick batch process.
3. Guest Posting on Relevant, Vetted Sites
Guest posting still works for authority building when targeting sites that are topically relevant and have real organic traffic of their own, not just a high DA number with no audience. Link building is cited as the most challenging SEO task by 41% of SEOs according to Siege Media, and guest posting remains one of the more reliable ways to overcome that difficulty.
Vetting matters more than volume here. A handful of placements on genuinely relevant, traffic-receiving sites outperforms a large batch of guest posts on low-quality link farms every time.
4. Internal Linking to Distribute Authority Efficiently
Strong internal linking spreads authority from your highest DA pages to newer or weaker pages across your own site, helping the whole domain rise more evenly. This is the only strategy on this list that requires no external outreach at all, since it works entirely with links you already control.
From experience, sites that audit and rebuild their internal linking structure after a content migration often see ranking improvements on older pages within weeks, well before any new external link building takes effect.
5. Removing or Disavowing Toxic Backlinks
A spam score above 30% is considered high risk according to Moz, and cleaning up toxic or spammy backlinks pointing to your site can protect the authority you have already earned. This is a defensive strategy rather than a growth one, but it prevents existing good links from being undermined.
43.7% of top-ranking pages have reciprocal links according to Ahrefs, which shows that not every link pattern flagged as risky in isolation is actually harmful, so disavowing should be selective rather than aggressive across the board.
6. Consistency Over Time Beats Bursts of Activity
A steady link building pace sustained over many months produces more durable authority growth than a short, intense burst followed by months of inactivity. Search engines and authority algorithms both tend to reward consistent signals over erratic spikes that look manufactured.
Backlinks remain one of Google’s top three ranking factors, and that consistency principle applies to the underlying ranking benefit just as much as it applies to the DA number itself.
Frequently Asked Questions
How long does it take to improve domain authority?
Meaningful movement typically takes a few months of consistent link building, though the exact timeline depends on starting authority and competition.
Does internal linking alone raise domain authority?
Internal linking redistributes authority you already have rather than creating new authority, so it works best alongside external link building, not as a replacement for it.
Is buying links a viable way to improve DA?
Paid links violate search engine guidelines and carry real risk of penalties, so earned or outreach-based links remain the safer long-term approach.
Can disavowing links lower my DA score?
Removing genuinely toxic links typically protects authority rather than lowering it, though disavowing should target clearly spammy links, not borderline ones.
Should I focus on DA or actual rankings first?
Rankings and traffic are the real goal, with DA serving as a useful proxy metric for tracking progress rather than the end target itself.
