A website can look polished and still attract little search traffic, while a modest-looking site may have a loyal audience and valuable links. If you are a photographer, creative freelancer or small-business owner comparing websites for a collaboration or guest post, a DA score can offer one useful clue—but it should never be the whole verdict. Understanding what the number represents helps you make better decisions about visibility and link building.
What a DA score measures
Domain Authority, usually shortened to DA, is a metric created by Moz to estimate how likely a website is to rank in search results compared with other sites. It is scored on a scale from 1 to 100. The calculation uses signals such as the number and quality of links pointing to a domain, along with other link-related factors. In general, a higher score suggests a stronger backlink profile relative to the sites being compared.
DA is not a Google ranking score, and Google does not use it to decide where a page appears in search results. It is best treated as a third-party comparison tool. For a fuller explanation of what a DA score means, including why it can change and how other SEO metrics differ, it helps to look beyond the number itself.
Why the score changes
A DA score can rise or fall even when a website owner has made no obvious changes. Moz updates its index and calculations, and the wider set of sites being measured can shift. A site may also gain new backlinks, lose old ones, or see links reassessed for quality. Because the scale is comparative and logarithmic, moving from 20 to 30 is not necessarily equivalent to moving from 70 to 80; progress often becomes harder at the upper end.
These fluctuations are a reason not to treat a small change as a success or failure on its own. If you monitor a site, compare its score over time using the same tool, and consider whether the movement reflects meaningful changes in its backlink profile or merely an updated data set.
DA, DR and Authority Score are not identical
SEO platforms use different methods and data to assess website authority. Ahrefs Domain Rating (DR) focuses on the strength of a domain’s backlink profile, while Semrush Authority Score combines link data with other signals intended to estimate overall authority. Moz DA has its own model and link index. Scores from these tools should not be compared as if they were grades on one shared scale.
If one site has a DA of 35 and another has a DR of 35, that does not mean they are equally authoritative. Choose one metric for consistent comparisons, and use others as additional perspectives rather than expecting exact agreement.
How to assess a website for a collaboration
For guest posting, a photography feature, or another partnership, the best destination is not automatically the one with the highest authority metric. A relevant site with real readers may be more valuable than a high-scoring site that has little connection to your work. Consider the audience, subject matter and quality of recent articles, as well as whether the site appears to publish useful material consistently.
Before agreeing to contribute, look for signs that the audience is active and genuine. Check whether articles attract relevant comments or are shared by real organisations and people. If traffic estimates are available, treat them as directional rather than exact. Review the site’s backlink profile for obvious patterns of unrelated, low-quality links, and check that its editorial standards fit the reputation you want to build.
- Relevance: Does the site cover a topic that fits your audience or expertise?
- Readers: Are its articles likely to reach people who could benefit from your work?
- Quality: Are the pages original, readable and maintained?
- Links: Do incoming links appear natural and connected to the site’s subject?
- Purpose: Is the proposed contribution useful to readers, rather than written only to place a link?
Visibility for freelancers is more than a domain metric
A DA score evaluates a website domain, not an individual freelancer’s talent, marketplace profile or likelihood of being hired. A photographer may have a strong portfolio and excellent client feedback without owning a high-authority website. Conversely, a high-scoring domain does not guarantee that a particular service page will bring in enquiries.
Freelancers can improve the information available to potential clients by keeping their portfolio, services and location clear wherever they present their work. On Osdire, for example, adding a city and country can help buyers discover relevant talent through location-based searches. These are among the profile details buyers check when they are looking for someone whose availability and location fit a project. That profile-level visibility is different from domain authority, but both illustrate why useful, accurate information matters online.
Use the number as a starting point
A DA score is most useful when it prompts better questions: Is this site relevant? Does it reach real readers? Are its links credible? For creators building an online presence, the durable work is publishing helpful material, earning links naturally and making services easy to understand. Track authority metrics if they help you compare progress, but pair them with traffic, audience fit and backlink quality. A score can inform a decision; it cannot make the decision for you.
