SEO: what is domain authority and how should you use it?
The practical answer to “what is domain authority” is that Domain Authority, or DA, is a Moz score intended to predict a website's performance in search results. Use it to compare relevant websites, while keeping inquiries and sales in a separate business report. The Domain Authority overview identifies Moz as its developer.
What decision should a Domain Authority score help you make?
Choose a question before checking the number. A useful starting question is: “Which competing businesses should we investigate more closely?” Write that at the top of your worksheet so the research stays connected to an actual decision.
Suppose, in a hypothetical example, you run a small bookkeeping firm. You want more inquiries from independent retailers. Start your comparison with firms serving those businesses, then inspect the pages that explain their services.
Keep a national newspaper out of that initial shortlist unless you have a specific reason to include it. Your first task is to understand the alternatives your prospective client might consider. Ask a colleague to challenge every entry that seems unrelated.
Separate the brand name from the everyday phrase
People can use “domain authority” loosely to mean a site's standing in its field. Domain Authority with capital letters names Moz's particular score. The supplied overview discusses both meanings, so ask anyone preparing a report to identify which they mean. Terminology overview.
For your own worksheet, reserve DA for the named metric. Give observations about expertise, useful content and customer confidence their own notes column. That keeps a numerical comparison separate from your judgment about the business.
How do Domain Authority, Domain Rating and PageRank differ?
Keep each metric in its own column. DA is associated with Moz's prediction of search performance, while Ahrefs' Domain Rating describes relative backlink profile strength. A backlink is a link from another website to yours; your backlink profile is the overall collection of those links. Authority metrics overview.
Ahrefs says DR is based on links and excludes website traffic, domain age and parent brand popularity. It also distinguishes DR, calculated between websites, from PageRank, calculated between pages. Ahrefs' explanation of DR.
| Metric | What it describes | How to use it here |
|---|---|---|
| Domain Authority | Moz's prediction of search performance | Compare DA with DA for relevant websites |
| Domain Rating | Ahrefs' relative measure of backlink strength | Use it as one input when reviewing links |
| PageRank | A calculation involving links between pages | Keep it distinct from vendor domain scores |
The definitions in this comparison come from the DA overview and Ahrefs' DR documentation. Do not combine the columns into an average authority score for your business.
Read the scale carefully
The supplied DA overview gives a range of 0–100. Ahrefs also gives DR a 0–100 range and describes it as logarithmic: gaining another point becomes harder higher up the scale. That explicit logarithmic explanation applies to DR in this source. DA range; DR scale.
Leave percentage signs out of your score column. Avoid translating a score into a promised number of leads. Set any sales target separately, with a clear definition of what counts as a relevant inquiry.
How can you check domain authority without creating a confusing report?
Use a repeatable record: website, metric, provider, date and reason for comparison. Before copying a result, check that the tool actually labels it Domain Authority or Domain Rating. If it simply says “authority,” read its definition first.
- Choose the target. Record the exact website you intend to compare.
- Identify the provider. Keep Moz DA and Ahrefs DR under separate headings.
- Record the date. Make it clear when each observation was collected.
- Explain relevance. State which customer need connects the competitor to your business.
- Add a next action. Choose one page or link worth investigating.
Ask your agency for this record instead of an isolated screenshot. If a screenshot is all you receive, request the missing provider and date before drawing conclusions. Keep the original record so a later review has something concrete to compare against.
What is a good domain authority score?
For planning, define “good” through a relevant comparison rather than a universal pass mark. Select businesses with similar customers and offers, then inspect what they publish. Treat a score difference as a question to investigate.
In a hypothetical example, a specialist repair shop compares itself with nearby repair businesses. The owner finds a useful repair-versus-replacement guide on a competitor's site. The next task is to decide whether customers need a better version of that explanation, with the shop's own experience and examples.
For that next step, use the content gap analysis guide. Prepare a list of missing customer answers before deciding how many articles to commission.
What should you inspect before pursuing a backlink?
Open the page and judge its relevance to the reader you want to reach. Write down why someone reading it would benefit from visiting your site. If you cannot explain that connection plainly, put the opportunity aside until you have a stronger reason.
A high DR should not end that review. Ahrefs explains that low-quality backlinks can increase the metric, so the score alone cannot establish that a link opportunity is worthwhile. DR limitations.
- Read the actual page where a link might appear.
- Identify the audience and the question the page answers.
- Choose the destination page on your own website.
- Check that the destination delivers the promised information.
- Write down the editorial reason for including your resource.
Prepare something worth referring to
Consider a hypothetical independent kitchen retailer. Instead of sending a generic request for a link, the owner prepares a clear measuring worksheet for customers planning a refit. The proposed outreach then explains who the worksheet helps and invites an editor to assess it.
This is a suggested project, not a claim that any publication accepted it. Define the first deliverable as a useful, checked resource. Treat publication and any resulting inquiries as outcomes to observe later.
If contributing an article is appropriate, use the guest posting guide to prepare the pitch. For a story with a real news angle, review small business press outreach. Choose the route that fits the material you actually have.
What can your team complete this week?
Set a deliverable you can inspect by the end of the week. I would choose a comparison worksheet, one improved customer resource and a short outreach shortlist. Assign an owner to each item before starting.
Start with one commercial priority
Choose a service or product group that matters to your business. Write the question a prospective customer needs answered before contacting you. Keep the first review focused on that question rather than turning it into an audit of everything you publish.
Review the evidence together
Ask one person to collect the competitor observations and another to review the selection. Separate what you saw from what you inferred. “This page contains a measuring checklist” is an observation; “our customers would use one” is a proposal you should test with them.
Finish one page before expanding
Draft the resource, check its details and ask someone unfamiliar with the project to use it. Note where they hesitate. Improve that section before preparing more articles around the same idea.
Then connect the resource to relevant pages on your own site using the internal linking guide. Choose link wording that tells readers what they will find. Check the destination yourself before marking the task complete.
Prepare a specific outreach note
Describe the resource, its intended reader and why it fits the recipient's publication. Avoid promising that it will improve anyone's rankings. Your immediate request is for an editorial review of something useful.
How should you respond when the score changes?
Ask what changed in the work and in the business before approving more spending. Keep completed tasks, metric observations and customer outcomes in separate parts of the report. Use the SEO reporting guide to structure that conversation.
In a hypothetical review, the authority score rises but relevant inquiries remain unchanged. Request a closer look at the landing pages, contact process and work delivered. Do not describe the score movement itself as additional revenue.
For the next review, agree on a small set of questions: what did we publish, what did we improve, what did customers do, and what should happen next? Keep the answers short enough that the business owner can challenge them.
