How to Increase Domain Authority
Understand what Domain Authority means, why a stronger backlink profile matters and how to build sustainable authority through relevant links, useful content and genuine digital visibility.
What is Domain Authority?
Domain Authority (DA) is a search-engine-ranking prediction metric created by Moz. It estimates how likely a website is to compete in search results when compared with other domains. The score runs from 1 to 100, with higher scores generally indicating a stronger, more established backlink profile.
It is important to be precise: Domain Authority is not a Google ranking factor, and Google does not use Moz’s score to decide where a page ranks. Instead, DA is a useful benchmark for SEO professionals, businesses and publishers who want a practical way to assess relative authority, evaluate link opportunities and track the quality of a website’s off-page SEO over time.
A growing DA score often accompanies stronger organic performance because both benefit from similar fundamentals: links from trusted and relevant websites, content that earns citations, clear site architecture and a credible brand presence. The target should never be to chase a number in isolation. The target is to build a website that deserves to rank and is easier for search engines and people to trust.
What is a good Domain Authority score?
There is no universal “good” DA score. The meaningful benchmark is the authority level of your closest organic competitors and the quality of the websites you want to earn links from.
A DA of 20 can be healthy for a new local business, while an ecommerce brand competing nationally may need a substantially stronger link profile to challenge established retailers. Because the scale is logarithmic, moving from DA 20 to 30 is normally easier than moving from DA 60 to 70.
Use score ranges as a rough guide only. A lower-DA, tightly relevant industry publication can deliver more qualified visitors and stronger topical relevance than a high-DA website with no connection to your market.
Why Domain Authority matters for SEO
DA does not directly rank a page, but it gives a helpful high-level view of the off-page strength that supports competitive SEO campaigns.
Benchmark real competitors
See whether the websites outranking you have materially stronger authority, then plan the content, technical SEO and link acquisition work needed to close the gap.
Assess backlink opportunities
Use DA alongside relevance, traffic, editorial quality and outbound-link standards when deciding where a guest post or digital PR placement is worth pursuing.
Track authority momentum
A healthy upward trend can indicate that your website is earning stronger referring domains and becoming more competitive within its search landscape.
Support harder keyword targets
Stronger sites often have a better foundation for competing on valuable commercial terms—provided the page intent, content quality and user experience are also right.
Build publisher confidence
A credible website, useful resources and a clean backlink profile can make relationship-led outreach, expert contributions and earned media opportunities easier.
Focus investment intelligently
DA gives another useful data point for prioritising your SEO audit, backlink strategy and content-led authority campaign.

How is Domain Authority calculated?
Moz uses a machine-learning model and a large collection of link signals to estimate the relative ranking strength of a domain.
Moz does not publish a fixed formula that lets anyone calculate a DA score manually. Its model assesses the broader link graph and considers many signals associated with a website’s ability to compete in search. This is why Domain Authority should be treated as a comparative estimate rather than an exact scorecard for SEO quality.
The score is also logarithmic. A move from DA 15 to DA 25 may be achievable through a sustained improvement in quality referring domains. Moving from DA 65 to DA 75 is much more difficult because websites in that range are competing with very established brands, publishers and organisations.
Referring domains
The number and diversity of unique websites that link to yours are usually more meaningful than a large quantity of repeated links from the same source.
Link quality and trust
Editorial links from established, relevant and well-maintained websites are more valuable than links placed only to manipulate a metric.
Topical relevance
A link should make sense to the reader. Industry relevance, context and natural placement all help make a backlink profile more credible.
Overall link profile
Moz’s model evaluates the wider structure of links pointing to a domain, including patterns that may indicate low quality or manipulation.
Domain Authority vs Domain Rating vs Authority Score
Different SEO platforms use different datasets and methodologies. Their scores cannot be converted directly, so use one primary metric consistently and always look beyond the number.

How to increase Domain Authority properly
The best route to a stronger Domain Authority score is the same route to a stronger website: earn relevant authority links, publish resources worth referencing and give every important page a solid technical and internal-linking foundation.
Earn high-quality referring domains
Prioritise links from trusted sites with a real editorial process and a genuine connection to your niche, audience or location. A diverse set of quality referring domains is healthier than repeated links from the same websites.
Use strategic guest posting
Well-written contributor content can earn contextual backlinks, reach new audiences and strengthen brand credibility. Explore our guest posting services for relevance-led placements.
Create content people cite
Original research, practical guides, useful templates, statistics, tools and expert commentary give publishers a genuine reason to reference your website rather than merely link for SEO purposes.
Strengthen topical authority
Build useful clusters around the services and subjects you want to rank for. Clear topical depth makes outreach more persuasive and helps visitors discover related pages once they arrive.
Improve internal linking
Internal links do not directly create external authority, but they help search engines understand your site structure and distribute value towards your most commercially important pages.
Audit your backlink profile
Review lost links, low-quality patterns and missed competitor opportunities regularly. A professional SEO audit can reveal where authority growth is being held back.
Build authority that supports rankings, not just a number
Our link building services focus on contextual placements, relevant publishers and content-led outreach. The aim is a stronger backlink profile that can support organic visibility, referral traffic and long-term SEO growth.
How long does it take to increase Domain Authority?
Authority growth is gradual. The right timescale depends on your starting point, competition, existing backlink profile, publishing activity and the quality of links you earn.
-
01
First 30 days: establish the foundation
Review your backlink profile, identify competitor gaps, strengthen priority pages and begin securing relevant placements. Moz may not reflect every new link immediately.
-
02
Months 2–4: build meaningful momentum
Consistent editorial links, useful content and better internal linking can start to improve the overall strength and diversity of your referring-domain profile.
-
03
Months 4–12: compound authority
As quality links accumulate, content earns more visibility and your brand becomes easier to reference, you are more likely to see sustained authority and ranking progress.
Common mistakes that stop Domain Authority growth
Many websites stall because they chase an authority number with tactics that add little real SEO value. A stronger profile is built on quality, relevance and consistency.
Buying bulk low-quality links
Hundreds of cheap backlinks from unrelated or poorly maintained sites rarely create a strong, trustworthy profile. They can also waste budget that should go towards real editorial opportunities.
Choosing links by DA alone
High DA does not automatically mean a placement is valuable. Check relevance, audience, organic visibility, content quality and whether the website looks genuinely curated.
Overusing exact-match anchors
Natural backlink profiles include brand names, URLs, topical phrases and varied anchors. Repeating one commercial keyword across every link looks artificial and adds unnecessary risk.
Ignoring the page being linked to
A link is stronger when it points to a useful, relevant page that answers the reader’s next question. Improve service pages and supporting content before scaling outreach.
Publishing content with no purpose
More pages do not automatically create authority. Publish genuinely helpful resources, case studies, guides and assets that deserve to be shared or cited.
Measuring only one metric
Track rankings, traffic, leads, conversions, referring domains and visibility alongside DA. This prevents your SEO campaign from becoming a number-chasing exercise.
