How to Increase Domain Authority: 9 Tactics That Actually Work

Every website owner who checks a search tool sooner or later meets the same number: Domain Authority. It is tempting to treat it as a grade handed down by Google itself. It is not, yet dismissing it entirely would be just as mistaken, because the things that lift the score are often the same things that lift real rankings, traffic and trust.

This guide explains the score in plain language, shows how to read it honestly, and works through nine tactics that genuinely move it. None is a shortcut. They are the patient, repeatable habits behind sites that search engines and readers learn to trust.

What Domain Authority Actually Is

Domain Authority, usually shortened to DA, is a predictive score created by Moz. It runs from zero to one hundred and estimates how likely a whole domain is to rank, based on a model trained on many ranking factors, around fifty of them, updated as its link index and ranking data change.

Google has said plainly that it does not use Domain Authority, or any third-party authority metric, in its ranking systems. The score is therefore a useful proxy, not an official input. It is valuable because it correlates with ranking: sites with strong link profiles, clean technical foundations and useful content tend both to rank well and to score highly.

How Domain Authority Is Calculated

Moz has never published the full formula, and the model is retrained periodically, so exact weights shift over time. What is well established is that links dominate. Two link factors matter most: how many distinct root domains link to you, and how trustworthy those linking domains are.

Diversity matters too. A hundred links from one domain do not carry the same weight as a hundred links from a hundred different domains, because breadth of endorsement signals genuine reputation. Secondary signals also feed in, including domain age, spam signals, and technical problems such as broken pages and redirect chains. Because the scale is logarithmic, it gets progressively harder to climb: moving from 20 to 30 is much easier than moving from 70 to 80.

What Counts as a Good Score

There is no single number that counts as good in every niche, and that is the first trap to avoid. A score of 40 might be dominant in a small specialist market and invisible in a fiercely competitive one such as finance or health. The honest benchmark is always relative: compare yourself with the sites that actually rank for your keywords.

As a rough guide, scores in the forties and fifties are solid for an established small or mid-sized business, sixty and above is strong, and eighty and above is exceptional territory for major brands and news organisations. New sites typically start between one and twenty, and that is normal, not a failure. Judge yourself on progress against your own past score and your closest competitors, not against the biggest sites on the web.

How to Check Your Domain Authority

The most direct way to check the score is Moz Link Explorer, which offers a free tier. Enter a domain and you will see its Domain Authority alongside linking domains, total inbound links and a ranking-keywords summary. Deeper reports show top pages by links, top linking domains, keywords you are discovered for, and links gained or lost over time.

The same report includes a top competitors view, listing sites ranking alongside you and their scores, which makes the relative benchmark concrete. MozBar, the free browser extension, shows Domain Authority and Page Authority for any page you visit. For a second opinion, SeoReviewTools and Linkgraph both provide authority lookups. Also know the parallel Ahrefs metric, Domain Rating: also zero to one hundred and largely link-based, but using a different index, so the two numbers rarely match exactly.

Domain Authority vs Page Authority

Domain Authority and Page Authority are siblings, and confusing them is a common mistake. Domain Authority predicts the ranking strength of an entire domain, while Page Authority predicts the ranking strength of a single page. Both run from zero to one hundred and draw on similar inputs, but Page Authority applies those inputs to one URL.

A page can therefore score much higher or lower than its domain: a widely linked guide on an ordinary site can outscore a stronger domain's homepage, and a new page on a powerful domain starts low until it earns its own links. Use Domain Authority to judge a site as a link partner or competitor, and Page Authority to judge which of your own pages carry weight or deserve internal links and promotion.

Tactic 1: Earn Links From Trusted Sites With Real Traffic

If one tactic matters most, it is this one. Domain Authority is, above all, a summary of your link profile, and no amount of on-page tweaking will compensate for a site that nobody trusted enough to link to. The links that move the score come from real sites with real audiences and editorial standards.

Start by studying your competitors in Moz Link Explorer. Note which domains link to the sites that outrank you, and identify realistic prospects: publications accepting expert contributions, blogs publishing guest posts, podcasts interviewing founders, and news outlets covering stories like yours. Guest posts work when they genuinely help the host's readers, and press releases work when they carry real news, such as a launch, study or partnership. Treat link building as a monthly habit with a real budget, and keep a record of every placement.

Where trusted links come from

Focus on placements that combine editorial standards with a real audience.

• Guest articles on respected industry blogs and publications that review contributions properly
• Press coverage earned by genuine news, research or expert commentary
• Resource pages, roundups and interviews where your expertise adds clear value

Tactic 2: Get Your On-Page SEO Right

Links bring authority to your site, but on-page SEO decides whether that authority is used well. Every page should have one clear main heading, followed by logical subheadings that break the content into scannable sections and show readers and search engines how the argument is organised.

Images deserve the same care: every meaningful image should carry descriptive alternative text and a sensible title where appropriate, so the page remains understandable to screen readers and image search. Internal anchor text should describe the destination in plain words, and search snippets should meet current search engine requirements and honestly promise what the page delivers. Audit with Netpeak Spider or Screaming Frog, and check individual pages with Moz On-Page Grader, MozBar and the PageRank Status extension.

Tactic 3: Fix Technical SEO Before It Costs You

Technical SEO is the unglamorous foundation under everything else. If search engines cannot crawl your site efficiently, if pages load slowly, or if visitors keep landing on errors, then content and links are fighting with a handicap. Check page speed with Sitechecker, WebPageTest and PageSpeed Insights.

Keep your platform maintained as well. More than forty percent of websites run on WordPress, and the same principle applies to any system: core software, themes and plugins must stay updated, because outdated components cause errors and slowdowns. Compress images properly, aiming for photographs saved as JPEGs under roughly one hundred kilobytes where quality allows. Review server status codes, fix unnecessary redirect chains, repair broken links, and check broken hreflang annotations where language targeting applies.

Tactic 4: Make Mobile-Friendliness Non-Negotiable

More than 4.3 billion people browse the internet on phones, and for many sites mobile visitors now outnumber desktop visitors outright. A site that works poorly on a phone is now a site that works poorly, full stop. Mobile-friendliness means readable text, tappable buttons, content that fits the screen, and fast loading on a mobile connection.

Start with Google Mobile-Friendly test, which reports specific errors such as text too small to read, clickable elements too close together, or content wider than the screen. Fix those errors template by template, since a single faulty template can affect hundreds of URLs. Then browse your own site on a real phone, on a slower connection, and try the actions that matter: reading an article, finding a contact page, starting an order. Every piece of friction you remove improves the chance that a mobile visitor stays, shares and links.

Tactic 5: Audit Your Backlink Profile Regularly

Not every link helps you. Links from spam networks, hacked pages, irrelevant directories and sites built purely to sell links can drag down the quality of your profile. A regular backlink audit is therefore maintenance, not paranoia. Moz Link Explorer lets you review top followed links and spot unnatural patterns, such as sudden spikes from unrelated sites.

When you find links you do not want, start with the polite route: contact the linking site's webmaster and ask for removal. Where removal is impossible, or where a site is clearly part of a spam network, use disavow and no-follow handling through Search Console to tell Google to discount those links. Use disavow carefully and narrowly, since wrongly disavowing good links can hurt you, and document every decision. Audit at least twice a year, and immediately after any event that might have attracted bad links.

Tactic 6: Build Smart Internal Linking

Internal links are the roads of your website. They tell search engines which pages matter, how pages relate, and how authority earned by one page can support others. A page that nothing links to is effectively invisible: readers cannot find it by browsing, and search engines may crawl it rarely and value it lightly.

Placement matters as much as presence. The first link on a page to a given destination tends to carry particular weight, so put your most important internal links in the body of the content, not buried in a footer repeated on every page. Link from context, with descriptive anchor text, and avoid linking every mention of a keyword, which dilutes each link's value. Audit with an all-in-one SEO plugin or a site crawler to find orphaned pages, excessive outgoing links and broken destinations, and fix them promptly.

Tactic 7: Use Social Media Properly

Social media deserves an honest description. Google has said that social signals, such as likes and follower counts, are not a direct ranking factor, and anyone promising that a viral post will directly raise your Domain Authority is overselling it. What social media genuinely does is amplify everything else in this guide.

Do the basics well and consistently. Maintain complete, current pages on the platforms where your audience actually spends time, including Facebook and Twitter, with a clear description and a working link to your site. Add share buttons to articles so a reader who found something useful can pass it on in one click, and prepare ready-made preview snippets for your own sharing: a short, accurate summary, a clean image and a working link. Share substantial pieces more than once, at different times and with different angles.

Tactic 8: Strengthen Site Structure and User Experience

Structure and user experience are where authority becomes visible to a visitor. A site protected by HTTPS with a valid SSL certificate signals basic trustworthiness from the first second, and browsers now warn visitors explicitly when that protection is missing. Navigation should be intuitive and quick.

Menus must collapse sensibly on mobile, search must be easy to find, and key actions such as contacting you or starting an order must work without frustration on a small screen. To understand how visitors actually behave, use heatmap and behaviour tools such as Plerdy, which show where people click, how far they scroll and where they hesitate. Visitors who stay, explore and share are the same visitors who link, so user-experience fixes have authority consequences even though they are not link building in the narrow sense.

Tactic 9: Create Content People Want to Bookmark and Share

All the tactics above support content, and none replaces it. Links are earned, in the end, by pages that deserve them. The content most likely to earn links is original, specific and genuinely useful in a way that cannot be found in ten other places: a well-researched guide, a data study, a clear comparison, a practical template, or an infographic explaining a complex idea at a glance.

Presentation matters for shareability. Original articles benefit from strong openings, honest headings and examples drawn from real work, while infographics benefit from readable type and a clear takeaway. Both benefit from legitimate sharing incentives, such as a downloadable checklist or companion template. Once a piece is published, distribute it deliberately: share it with your email list, with relevant communities where self-promotion is welcome, and directly with editors who have covered similar topics. Align with Google's helpful-content direction: write for people first, from genuine expertise, covering a topic thoroughly enough that a reader leaves satisfied.

How Long Does It Take to See Results

Timelines are where expectations most often go wrong, so set them honestly. After you earn a new link or fix a technical problem, the first movements in a tool score can appear within days, once the linking page is crawled and the tool index updates. Those early movements are often small and noisy, and a single placement rarely transforms a score overnight.

Reaching a score of sixty or above is a matter of months, and for competitive niches, of sustained work over a year or more. That reflects the logarithmic scale and the strength of the competition: you are not just adding links, you are outpacing sites that are also adding links. Plan in quarters, building a publishing rhythm and a regular outreach habit. If your score falls, check first whether you lost important links, whether a migration broke internal structure, whether spam links appeared, or whether the scoring model itself was updated.

Start Building Authority That Lasts

Domain Authority will not make your business successful on its own, but the work behind it will. Earn links from sites people trust, publish content people want to keep, keep your site fast, mobile-friendly and technically clean, audit what points at you, and link your own pages together sensibly.

If trusted links are the missing piece in your plan, a well-placed press release can accelerate tactic one considerably. Press releases published on trusted outlets put your story in front of journalists and readers who already trust those publications, and coverage earned that way often leads to further links, citations and brand searches. To put that tactic to work for your own site, explore the options on /pricing and choose a distribution plan that fits your goals.
