Domain Authority (DA) is a Moz metric scored 0 to 100 based on backlink quality. Most small businesses need DA 30 to 45 to rank for core keywords. Improve it by earning links from high-DA sites, fixing crawl issues, and tightening internal links.
What Domain Authority Actually Measures (And What It Does Not)
Moz created Domain Authority as a competitive benchmarking tool, not as a replacement for Google’s own ranking signals. Google does not use DA. What DA does well is give you a single number to compare your site’s link strength against a competitor’s before you decide whether to target a keyword or pitch for a link.
DA is calculated on a logarithmic scale, which matters for goal-setting. Climbing from 20 to 30 requires far less effort than climbing from 60 to 70. If your competitors are sitting at DA 35 and you are at DA 22, closing that gap is realistic within 12 to 18 months with consistent effort. Chasing DA 70 when your whole niche lives at DA 30 is an inefficient use of budget and time.
One thing most guides skip: Moz recalculates DA continuously, and your score can drop even when your link profile is growing. That happens because the calculation is relative. If large sites in your industry are acquiring links faster than you, your score may slide even though you did nothing wrong. Do not panic at a short-term dip. Track a rolling 90-day trend, not a month-over-month snapshot.
DA vs. DR: a quick distinction. Domain Authority is Moz’s metric. Domain Rating (DR) is Ahrefs’ equivalent. Both run 0 to 100 and measure backlink strength, but they weight links differently, so the numbers rarely match. Choose one tool and track it consistently. Mixing them across reports creates confusion without adding insight.
The Fastest Route to a Higher DA Score
Earn one or two links from high-DA, relevant sites in your niche before doing anything else. A single placement in a local news outlet or industry publication at DA 65 or above will move your score faster than any combination of directory submissions, social signals, or on-page tweaks.
How to Set a Realistic DA Target
Before you do anything else, pull your top 10 competitors for your most important keyword and check their DA scores. Find the median. Your near-term target should be 5 to 10 points above that median, not some round number you read in a blog post.
For a Phoenix HVAC company ranking locally, for example, you are not competing against national home improvement sites. You are competing against other Phoenix contractors, local franchise locations, and city-specific directories. Many of those pages sit at DA 20 to 40. Reaching DA 35 to 45 is often enough to compete for the terms that drive real calls, which is a very different goal than chasing DA 60.
Pro Tip: Run a DA check on every URL ranking in your top 10 for a target keyword, not just the homepage. Page Authority (PA) on a specific page, not just site-wide DA, is often what you are actually competing against for that search.
The Backlink Playbook: How to Actually Get High-DA Links
Every guide says “get high-quality backlinks.” Here is a realistic process for doing that as a small business.
A note on guest posting in 2026. Guest posts on low-traffic, general-topic sites carry significantly less value than they did several years ago, partly because of Google’s link spam updates and partly because Moz’s algorithm weights traffic-correlated links more heavily. Prioritize digital PR (being quoted or cited in real publications) and resource page placements over mass guest post outreach.
Internal Linking: The DA Lever Most Small Business Sites Ignore
Every backlink you earn deposits link equity into your domain. Where that equity flows internally determines how much of it reaches your most important pages. A flat, unstructured site wastes most of the equity on pages that do not drive revenue.
A strong internal linking structure means every new backlink you earn amplifies across your whole site, not just the one page it lands on. Small business sites with 20 to 50 pages can implement this in a single afternoon and see crawl improvements within weeks.
Here is how to build it properly. Start with your highest-value pages, typically your service pages and your homepage. Every blog post or supporting page on your site should link back to at least one of those high-value pages using descriptive anchor text. Then link between related blog posts so Googlebot and Moz’s crawler can reach every page without hitting dead ends.
Check your site for orphaned pages, pages with no internal links pointing to them. Orphaned pages receive zero link equity regardless of how many backlinks your domain has. Plugging those gaps is free and takes an hour. For a deeper look at avoiding the structural problems that hurt small business sites, see our guide on common small business website mistakes.
Pro Tip: When you publish a new page, spend 10 minutes finding 3 to 5 existing pages on your site that are topically related and add a contextual link to the new page from each one. This is the simplest internal linking habit that most site owners never build.
Technical SEO as the Foundation Under Your DA Score
Backlinks drive DA, but technical health determines whether Moz’s crawler (and Google’s) can fully index your site and pass that link equity where it belongs. A site with crawl errors, broken links, or slow page speed has a ceiling on how far DA can climb regardless of the links you earn.
This is not theoretical. We worked with a Phoenix home services client who was stuck at DA 18 for over a year despite legitimate links from suppliers and local directories. A crawl audit found 47 internal broken links and three service pages blocked by a stray noindex tag left over from a site redesign. Fixing those two issues alone, without adding a single new backlink, resulted in Moz’s next recalculation showing a jump to DA 24. The links were already there doing partial work. The technical cleanup let the existing equity flow properly.
| Technical Issue | DA Impact | Priority |
|---|---|---|
| Broken internal links (404s) | Wastes internal link equity | High |
| Missing or duplicate meta tags | Dilutes page-level signals | Medium |
| Slow page load (over 3 seconds) | Reduces crawl budget on large sites | Medium |
| Non-HTTPS pages | Can trigger security flags, devalue links | High |
| Noindex tags on important pages | Blocks those pages from accumulating DA credit | High |
| Duplicate content across URLs | Splits link equity between versions | Medium |
Run a free crawl using Screaming Frog (up to 500 URLs free) or Google Search Console’s Coverage report. Fix broken links first, then HTTPS issues, then duplicate content. For small sites under 50 pages, this process takes a few hours and often produces crawl improvements within 2 to 4 weeks of Moz recalculating.

Cleaning Up a Toxic Link Profile
If your site has been around for more than two years, you likely have some low-quality inbound links from scrapers, irrelevant directories, or old link schemes. These do not automatically tank your DA, but a high ratio of low-quality links to high-quality ones dilutes your score.
Start by sorting your link profile by spam score inside Moz (or by referring domain DR inside Ahrefs). Any link from a site with a spam score above 60 in Moz is worth reviewing. Do not disavow everything, as over-disavowing is a real mistake. Disavow only links that are clearly manipulative, from link farms, or from completely irrelevant foreign-language sites with no legitimate reason to link to you. Submit the disavow file through Google Search Console.
Pro Tip: Before disavowing, try a manual removal request first. Email the site owner and ask for removal. If you get no response within 30 days, add it to your disavow file. Google weighs the disavow file more seriously when you can document outreach attempts.
DA and Local SEO: How It Plays Out for Phoenix Businesses
For local service businesses, DA-building and local SEO are not separate strategies. They overlap directly. Citations in Arizona-focused directories (Arizona Business, local Better Business Bureau chapters, Phoenix Chamber of Commerce) build links from high-DA local sites while simultaneously strengthening your Google Business Profile signals.
NAP consistency, keeping your business name, address, and phone number identical across every directory listing and citation, is one of the most direct ways to strengthen domain reputation signals for local businesses. Inconsistent NAP data across Yelp, Google, and local directories creates trust problems that suppress both local pack rankings and the authority those citations pass to your domain. Audit your listings once a quarter and correct any discrepancies before they compound.
Local news coverage is the highest-ROI link source most Phoenix small businesses never pursue. A quote in a Phoenix Business Journal article or a feature in a neighborhood blog like Arcadia Camelback Connection carries a link from a DA 50 to 70 source that no amount of generic guest posting can replicate. Pitch local reporters with genuinely local angles: hiring trends, neighborhood data, community involvement.

What DA Improvement Actually Looks Like on a Timeline
General industry observation: new sites (under 12 months old) rarely exceed DA 20 to 25 even with active link building, because Moz weights domain age and link accumulation patterns over time. Most small business sites building links deliberately can expect to gain 5 to 10 DA points per year in the early stages (DA 10 to 40 range), slowing as they move higher.
| DA Range | Typical Timeline to Advance 10 Points | Primary Driver | Relevant for Most Small Businesses? |
|---|---|---|---|
| 1 to 20 | 3 to 9 months | Any quality links plus technical cleanup | Yes |
| 20 to 40 | 9 to 18 months | Consistent link earning, internal linking | Yes |
| 40 to 60 | 18 to 36 months | Digital PR, high-authority placements | Sometimes (regional or multi-location businesses) |
| 60 to 80 | 3 to 6 years | Scale, brand authority, consistent publishing | Rarely a practical goal for local small businesses |
These are general ranges based on commonly reported patterns across the SEO industry, not guarantees. Competitive niches can take longer at every stage. Most local Phoenix businesses will find the DA 20 to 40 range is where the work that matters happens.
What We See Running Campaigns
The Phoenix home services example in the technical SEO section above is one of the cleaner illustrations of a pattern we see repeatedly: clients arrive having done real link-building work, yet their DA has stalled. The culprit is almost always a crawl or indexation issue that prevents existing link equity from circulating. Fixing the technical layer first is nearly always more efficient than chasing new backlinks before the foundation is sound.
The second consistent pattern involves local media. Phoenix businesses regularly underestimate the DA value sitting in outlets like the Arizona Republic and Phoenix Business Journal, and even in neighborhood-level blogs that maintain active WordPress archives. The businesses that grow DA fastest in competitive Phoenix verticals, home services, legal, medical, are rarely the ones sending the most outreach emails. They are the ones that invest in one or two newsworthy stories per year and pitch them to local reporters with a clear, local angle. One placed story can deliver a link that outperforms an entire quarter of directory submissions.

Frequently asked questions
What is the fastest way to increase domain authority?
Earn a small number of high-DA, relevant backlinks rather than dozens of low-quality ones. A single link from a DA 70 local news outlet or industry publication moves the needle faster than 50 directory listings. Fix technical crawl errors at the same time so Moz can fully index your site.
What is a good domain authority for a website?
There is no universal answer. A DA of 30 to 45 is a practical target for most small businesses competing in local or niche markets, while DA 20 can be enough for low-competition local searches. The right target is 5 to 10 points above the median DA of the sites currently ranking for your most important keywords.
How to improve your domain reputation?
Remove or disavow spammy inbound links, publish original content that earns organic citations, and resolve any security or spam flags in Google Search Console. For local businesses, keeping your NAP (name, address, phone) consistent across all directory listings is the most direct way to strengthen domain reputation signals.
What is the difference between Domain Authority and Domain Rating?
Domain Authority (DA) is calculated by Moz. Domain Rating (DR) is calculated by Ahrefs. Both run 0 to 100 and measure backlink strength, but they weight links differently, so the scores rarely match. Pick one tool and track it consistently rather than mixing the two.
