A photography student looking for places to publish a portfolio story, or a musician pitching an educational article, may encounter a website’s DA score during research. The number can help compare sites, but it is not a verdict on their quality or a promise that a link will improve search rankings. Understanding what it measures—and what it leaves out—helps creators make better decisions about outreach and their own online presence.
What a DA score tells you
Domain Authority, usually shortened to DA, is a metric developed 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 draws on information about a site’s backlink profile, including the number and characteristics of domains linking to it. The score is best understood as a comparative estimate, not a direct measurement of trust, expertise, audience size, or Google rankings.
That distinction matters when you are assessing a possible publication or partner. A high score may indicate that a site has built a substantial link profile, but it does not tell you whether its readers care about music education, photography, or the particular subject you want to cover. A smaller specialist site may be a better fit than a large general-interest publication if its audience is engaged and closely aligned with your work.
For a fuller explanation of the metric, its changing scores, and comparisons with other tools, see this guide to the DA score.
Why the number changes
A DA score can rise or fall as Moz updates its index and as the wider link landscape changes. A website may gain links from new domains, lose links when pages disappear, or see its score shift as other sites develop stronger link profiles. Because the scale is comparative and logarithmic, gaining a few points at one level may be easier than making the same jump at a higher level.
A change does not automatically mean a site has become better or worse. If you are monitoring your own portfolio or publication, look at the trend alongside real outcomes: relevant visitors, inquiries, readership, and the quality of sites that mention you. Avoid changing a sound content strategy simply to chase a particular number.
DA, DR, and Authority Score are not interchangeable
Several SEO platforms publish authority-style metrics, but each uses its own data and calculations. Moz DA, Ahrefs Domain Rating (DR), and Semrush Authority Score are not standardized industry measurements. Two tools can assign different values to the same domain without either number being a definitive ranking signal. Compare websites using the same tool when you need a consistent shortlist, and treat cross-tool differences as a reason to investigate rather than as a contradiction.
Search engines do not use Moz’s DA score as an official ranking factor. It is a third-party estimate that can help organize research, not a number to optimize for in isolation. The same caution applies to DR and other proprietary scores. A site’s usefulness depends on more than its metric.
How to assess a site for collaboration
If you are considering a guest contribution, interview, or link-building opportunity, use authority scores as one filter among several. Check whether the website publishes genuine work in your area, whether its recent articles are useful and carefully edited, and whether its audience matches the people you hope to reach. For a photography project, relevant readers might be students, working photographers, or local arts organizations. For a music tutorial, a smaller site with a strong teaching focus may deliver more value than a broad site with a higher score.
-
Review topical fit: Does the site regularly cover subjects connected to your expertise?
-
Look at audience signals: Are the pages current, readable, and likely to attract the people you want to reach?
-
Inspect backlinks and content: Are links and articles editorially relevant, or does the site appear to publish unrelated material in bulk?
-
Consider the purpose: Will the collaboration help readers, build a meaningful professional relationship, or showcase your work?
These checks also help distinguish a worthwhile opportunity from a site that looks impressive in a metrics report but offers little relevance. A link from a credible, related page can be more useful to your reputation and audience than a link chosen solely because a domain has a high score.
Visibility for independent creatives
Creators do not only need to evaluate other websites; they also need to be findable when potential clients search for a particular skill or location. Freelancers who offer photography, music production, design, or writing services can make their profiles more informative by clearly describing their work and where they are based. On a marketplace such as Osdire, adding a city and country can help improve freelance search visibility for buyers using location-based searches. The practical steps are covered in its guide to adding your location.
Location is one useful detail, not a substitute for a strong portfolio, accurate service descriptions, and responsive communication. Together, those elements give buyers a clearer picture of whether you are suited to a project. Likewise, when evaluating a publication, combine its DA score with relevance, content quality, and audience fit. Used in that broader context, the metric can support a decision without making it for you.
