If you’re a London business investing in your website, you’ve probably heard of a score called Domain Authority. Understanding how Domain Authority is computed might help you comprehend what that number really means. It’s a third-party assessment of how well a website can rank, not a Google score or a promise of search traffic.
- Domain Authority (DA) is a Moz statistic, not a direct ranking criterion utilised by Google.
- It is mostly based on the backlink profile of a website and other link-related factors for its calculation.
- A DA score is most relevant when comparing similar sites, not as a target score by itself.
- Long-term priority should be relevant and trustworthy links and really beneficial material, not shortcuts.
- SEO work must have a clear scope, measurable duties and realistic objectives.
What Domain Authority Is Measured With?
Domain Authority (DA) is a 1-100 value that predicts how well a website will rank on search engines. Moz created the measure to utilise in its own SEO tools. Other SEO tools employ other measures, such as Domain Rating and Authority Score; thus, their statistics are not interchangeable.
This distinction is especially important when comparing a local restaurant, independent fashion brand or professional services business against its competitors. A DA score can be a quick way to get a sense of a website’s relative link strength, but it doesn’t tell you if the site is bringing in customers, offering helpful information or ranking for the searches that matter to the business.

How Domain Authority is Calculated
Moz has its own system for evaluating several signals, with a site’s backlink profile being one of the major ones. Backlinks are links from other websites to your site. It looks at things like the quantity and quality of domains that connect to your site, how those sites link to other sites, and indications that may suggest spam or low-quality links.
Moz – Uses machine learning to forecast how well a website might do in search relative to other sites. The actual formula is not public, and the score can vary anytime Moz updates its index or alters the way the calculation works.
Domain Authority is also measured on a logarithmic scale. “From a practical standpoint, it’s usually easier to go from 20 to 30 than it is from 70 to 80.” See this guide to Domain Authority for a more in-depth discussion of the measure and its limits.
Why a Higher Score Does Not Guarantee
Moz’s DA score does not affect Google rankings. Even a page on a website with a low DA score can rank well for a local search if the page is relevant and beneficial to the searcher. A larger site might have a higher score too, with a good backlink profile, but may not deliver the specific information someone is seeking.
Each platform has its own index and methodology; therefore, SEO platforms range in authority scores also. Therefore, a DA of 35 should not be automatically deemed the same as a score of 35 from another SEO tool.
The best way is to compare apples to apples. When looking for competitors, use the same platform and focus on companies that are in a comparable market, geography and niche.
What Can a Business Do to Improve Its Standing?

Instead of simply aiming to inflate a number, focus on the aspects that can help you achieve better search performance:
Create useful pages: Clearly present your services, prices, methods and local knowledge. Page content should answer real client questions, not just repeat a target term.
Get relevant links: Local alliances, trade associations, reputable media coverage and truly useful resources can all lead to opportunities for connections from websites with a real reason to mention your firm.
Review current links: Review the websites that link to you and decide if they are relevant and reputable. Avoid buying huge link bundles or schemes that promise a fast improvement in your authority score.
Keep the site easy to use: Easy navigation, mobile-friendly pages and accurate business information make your website easier for visitors to utilise. These modifications won’t directly boost your DA, but they will make your site more beneficial to your clients.
Measure outcomes: Apart from any authority score, keep track of what matters to the business, such as relevant search visibility, enquiries, bookings and sales.
How to Choose SEO Help Without Buying a Phone Number
SEO might include content planning, local search optimisation, technical audits and link outreach. Before you hire a freelancer or agency, ask what work they will do, what access they will need, how they will report progress, and what activities are excluded from the agreed pricing.
Be wary of anyone who guarantees a specific DA score or a first-place ranking. No SEO provider can control how search engines rank every search query.
Look for SEO services that give concrete deliverables, such as a technical audit, a prioritised action plan, or specific content projects. Osdire is a freelance marketplace that allows buyers to compare suppliers and agree on the scope of a job before work begins. Regardless of the path you take, make sure the effort is in service of your business goals and not just a headline metric.
How to Use DA in a Competitor Analysis
Start with a small group of actual rivals. You want firms that go after the same customers and search terms, not only the largest brands in your field.
Use the same SEO tool to check their authority scores. Then look at the pages that attract their backlinks and what themes those sites cover. A more useful inquiry is not simply, “How do we get their score?” Instead ask, “Why are other websites linked to them, and is there a valid way for our firm to give similar value?
Rather than reacting to every little change, repeat the comparison every few months. If your score goes down, see if the SEO tool has updated its data and if any important links have been lost or modified.
Then check your actual search visibility and the queries your website produces. Those numbers are significantly closer to the business results you ultimately seek.
The Bottom Line
Domain Authority should be utilised as a comparative SEO metric. It’s based on a third-party methodology that takes into account the strength and character of a website’s links. It is not a direct Google ranking signal.
Use DA to learn more about your competition and to evaluate your own link profile, but don’t make the score the aim. If you want sustainable search presence, relevant material, credible mentions, useful information, and practical website enhancements are the higher-value priorities.
