- You cannot see a competitor's real analytics. You can track modelled estimates that are directionally useful, and the shape of the trend is what to monitor — not the absolute number.
- Two tools beat one. Cross-reference Similarweb and either Semrush or Ahrefs, and treat any figure that agrees within 30 percent as a fair estimate of your competitors' traffic.
- Keyword rankings, referring domains and top pages tell you far more about what your competitors are doing than the headline traffic number does.
- Monitor monthly, not weekly. A one-hour cadence with two tools and a shared spreadsheet is what most competitor monitoring programmes actually need.
- The point of the analysis is to decide what your team should do next — not to build a dashboard for its own sake.

Domain Authority Explained: How It Works and How to Improve It
Every B2B marketing team wants to get competitor website traffic estimates that hold up under scrutiny — and most end up paying for tools they never open twice. This piece covers the analysis method that actually works, the tools worth a subscription, and a monthly workflow SMEs, scale-ups and agencies can repeat without hiring an analyst.
The short version
Why competitor website traffic analysis matters
Every team benchmarks against something. The question is whether the benchmark is a real competitor or a generic industry average — and a competitor benchmark is worth several times more. A number from your own niche tells your team what "good" looks like on a website of similar age and commercial model. A global average tells you nothing you can act on.
What a rigorous competitor analysis really answers is not "how much traffic does the competitor get?" — it is "which of their plays are working, and which of those can our team copy or leapfrog?" That is a more actionable question, and it is the reason a competitor monitoring programme changes decisions rather than decorating reports.
For SMEs, scale-ups, agencies and SaaS marketing teams the same three use cases keep coming up. First, sizing the market — competitors with visible traffic prove the demand exists. Second, prioritising channels — if two competitors both grew through content and one through paid, your next quarter is probably about content. Third, defending share — a competitor pulling ahead on branded search is a signal you need to track and respond to, not a spreadsheet.
None of that needs a full-time analyst. What it needs is the right tools, the right handful of metrics to track, and a workflow the marketing owner can keep up with.
What your competitors leak about their website traffic
A competitor cannot hide most of what matters. Their website is public, their content is public, their inbound links are public, and every third-party tool that models website traffic reads the same signals. Knowing what to track — and what to skip — helps your team spend an hour on the data that changes decisions.
| What competitors leak | What tool sees it | How much decision it supports |
|---|---|---|
| Estimated monthly website traffic | Similarweb, Semrush, Ahrefs | Directional — trend is more reliable than the number |
| Ranking keywords and top pages | Ahrefs, Semrush, Serpstat | High — tells you what content is actually working |
| Referring domains and link velocity | Ahrefs, Majestic | High — shows the authority strategy your competitors use |
| Paid keywords and ad copy | Semrush, SpyFu | Useful for scale-ups; SMEs can usually skip it |
| Social share of voice | BuzzSumo, Sparktoro | Useful for content-heavy competitors |
| Technology stack | BuiltWith, Wappalyzer | Rarely changes a marketing decision — skip most months |
Notice how much of what your competitors leak lives in tools your team can open for free. The paid tiers add depth on top pages, keyword history and referring domains — the layers that support real decisions. The rest is noise most of the time.
Tool choice
Which tools to use for competitor traffic analysis
Four tools cover 95 percent of what a marketing team needs to track competitors. Pick two — a traffic tool and a search tool — and skip the rest until a specific question demands them.
Similarweb — traffic and channel mix
The default tool for a headline website traffic estimate, channel split and country breakdown for any competitor. Trend is reliable, absolute numbers are not — treat the graph as the truth and the label as a rough guide.
Ahrefs — keywords and links
The strongest tool for the keyword universe your competitor ranks for and the referring domains they have earned. Use it to see what content and authority your competitors are actually building.
Semrush — the all-rounder
A single tool that covers traffic estimates, paid search keywords, position tracking and ad copy. Weaker than Ahrefs on links and than Similarweb on channel mix, but a fair choice if your marketing team can only fund one paid tool.
Google Search Console + a spreadsheet
Free, and the only tool that reports your own website's true position. Combine what you rank for with a competitor's public ranking data from Ahrefs, and you have a keyword gap analysis no paid tool sells better.
How to get competitor website traffic estimates that hold up
The single biggest mistake teams make on a competitor traffic analysis is trusting a single tool. Every tool models website traffic from a different panel, so their numbers disagree — sometimes by a factor of two. The fix is straightforward: use two tools, note where they agree and where they diverge, and treat the agreement zone as the fair estimate.
Here is the practical method our analysts use to get competitor website traffic figures that survive a management review. It takes about twenty minutes per competitor and delivers a number you can defend without an asterisk.
- Pull the monthly traffic estimate from Similarweb. Note the number and the trend line for the last twelve months. If the tool marks the estimate as "low confidence" — a small competitor site — the absolute figure is not worth quoting.
- Pull the equivalent from Ahrefs or Semrush. Focus on organic traffic; each tool models it separately, so a second number is a second data point.
- Compare the two. If they land within 30 percent of each other, take the midpoint. If they diverge more, quote both and let the reader see the range.
- Cross-check against a proxy signal. Referring domains, ranking keyword count and branded search volume all move alongside real traffic — a competitor's tool numbers should not disagree with those proxies.
- Log the number in a shared spreadsheet. One row per competitor, one column per month. The value of the analysis compounds only if the history exists.
Do this once and the numbers look noisy. Do it every month for two quarters and the shape of each competitor's website traffic becomes obvious — who is genuinely growing, who is stalling, and who is buying visibility rather than earning it. That shape is what a marketing team can actually act on.
How much traffic does my competitor get, really?
"How much traffic does my competitor get?" is the first question a marketing owner asks, and the honest answer is that nobody outside the competitor's own analytics knows the exact number. The tools estimate it, and the estimates disagree — often by a wide margin. What you can trust is the order of magnitude and the direction of travel.
To make that concrete, here are the bands our analysts use when a client asks how much traffic a competitor's website is really getting. Treat them as directional, and always compare a competitor against websites of similar age and niche rather than against a global average.
| Modelled monthly traffic | What it usually means | How much confidence to put in the number |
|---|---|---|
| Under 5,000 sessions | New or small B2B website, likely under the tool's detection floor | Low — the estimate can be off by 3x either way |
| 5,000 to 50,000 | Established SME website with a working content or paid channel | Medium — trend reliable, absolute number roughly indicative |
| 50,000 to 500,000 | Scale-up website with a real content library and link base | Good — tools converge, trend is highly reliable |
| 500,000+ | Category leader; tools disagree on absolutes but agree on shape | Good on trend, poor on the label |
What matters commercially is rarely the headline number. It is how much of that competitor traffic your website could plausibly capture, which comes back to keyword overlap, referring domain overlap, and the shape of each competitor's channel mix. A competitor with 200,000 monthly sessions almost entirely from branded search is a much weaker threat than one with 40,000 sessions from your exact commercial keywords.
Understanding Domain Authority
What is domain authority? It is a Moz metric that estimates a site's ranking strength. The score runs from 1 to 100.
The domain authority definition is simple. It is a link-based estimate for an entire domain. Moz uses link data and search results to build the score.
What does domain authority mean for your site? It shows how your link profile compares with other sites. It does not measure sales, traffic, or content quality by itself.
Domain authority in SEO works best as a benchmark. It can guide link work and competitor analysis. It cannot predict every page's ranking.
Many people ask, “What is the domain authority of my site?” A tool must crawl your domain first. The result can vary by tool, index, and date.
- Domain Authority covers a whole domain
- Page Authority covers one page
- Both Moz scores use a 1 to 100 scale
- Neither score is a Google ranking factor
For Moz's own scope, see Moz's Domain Authority guide. The guide explains why the score is a comparison tool, not a promise.
How Domain Authority Is Calculated
How does Moz calculate domain authority? It reviews the quality and number of links to a site. It also weighs the sites that send those links.
The model then compares link patterns with sites that rank in search results. Moz does not share one simple public formula. Its model and link index can change.
This is why a domain authority test is not a fixed lab result. Run the same domain authority search in the same tool. Then record the date and score.
A domain authority calculator can give a quick view. It cannot replace a full backlink review. Raw link totals often hide weak or repeated sources.
Link quality matters more than simple volume. One useful link can beat many links from poor sites. Relevance, trust, and placement all shape the value.
What affects the score?
- Quality and number of linking domains
- Relevance of referring sites
- Strength of pages that send links
- Natural patterns in your backlink profile
- Changes in the tool's link index
Domain level link authority features can help explain the model. These include source strength, link flow, and referring domain spread. They do not tell the full story of a site.
Organic traffic is not a direct part of every authority score. Yet useful traffic can lead to more shares, mentions, and links. Those gains may lift the score over time.
Why Domain Authority Matters in SEO
Why is domain authority important? It gives teams a shared way to compare link strength. It can also show whether link work keeps pace with close rivals.
High domain authority often correlates with better rankings. Strong sites tend to earn useful links and publish helpful pages. The score itself does not cause those rankings.
Google does not use Moz's score in its ranking system. Google assesses pages through many signals. Relevance and page quality still matter most for each search.
Domain authority ranking only has value within a fair comparison set. A score of 40 may look strong in one niche. It may look low beside major publishers.
Use site domain authority as one clue. Add rankings, traffic, conversions, and content gaps. That mix gives a more useful view of performance.
How to check domain authority in a useful way
- Choose one trusted tool and sign in.
- Enter the full domain or target subdomain.
- Note Domain Authority, links, and referring domains.
- Compare close competitors in the same tool.
- Check key pages with Page Authority and ranking data.
This process helps you check domain authority of a site without chasing random scores. It also helps you find domain authority data that fits your market.
Comparing Domain Authority Metrics
Moz Domain Authority, Ahrefs Domain Rating, and Semrush Authority Score measure related ideas. Each tool uses a different link index and model.
Ahrefs Domain Rating focuses on the strength of a site's link network. Semrush Authority Score blends link data with other site signals. Moz uses its own model to estimate ranking strength.
These values are not equal. A score of 50 in one tool does not match 50 in another. Pick one tool for routine tracking.
| Metric | Provider | Useful for |
|---|---|---|
| Domain Authority | Moz | Comparing likely ranking strength |
| Domain Rating | Ahrefs | Reviewing link network strength |
| Authority Score | Semrush | Reviewing links and wider site signals |
Some users search for “moz rank domain authority” or “majestic domain authority.” These terms mix separate tools and metrics. Check the provider before you compare results.
Ahrefs historic domain rating and Ahrefs historical domain rating reports can show past link strength. They do not recreate Moz's historical domain authority. Use one provider when you track domain authority over time.
Mozbar domain authority data may look different from a newer Moz report. Moz can change its tools, index, and score model. If Moz is not showing Domain Authority anymore, check the account view or use its current link tool.
Factors That Shape Domain Authority
Backlinks are a key part of domain authority. A useful backlink comes from a real site with a related audience. It should sit near clear, helpful content.
Referring domain diversity matters too. Ten trusted sites can show wider support than ten links from one site. A broad link base looks more natural.
Content quality supports link growth. Strong pages answer clear questions with facts, examples, or fresh insight. Thin pages rarely earn lasting links.
Site health also plays a role in your wider SEO work. Broken pages can waste good links. Slow pages can reduce trust and visits.
Why scores rise and fall
Why did my domain authority go down? A tool may lose links from its index. Competitors may gain stronger links. The model may also change.
Why is my domain authority so low? Your site may have few referring domains. The links may lack trust or relevance. A young site may simply need more time.
There is no useful average domain authority for every market. Scores vary by niche, age, competition, and link supply. Compare against close competitors instead.
Domain age is not the same as authority. “What is domain age in SEO?” It is the length of time a domain has existed. Age alone does not create trust or strong links.
Improving Your Domain Authority
How to raise your domain authority? Start with pages worth citing. Build clear guides, original studies, tools, and useful data.
Then earn links from relevant sources. Outreach works best when the page solves a real need. Do not buy large batches of weak links.
How to gain domain authority takes steady work. Review your backlink profile each month. Fix broken targets and reclaim lost links.
- Improve pages that already earn impressions
- Create data that others can cite
- Pitch useful resources to relevant publishers
- Remove or disavow harmful links only when needed
- Track links, rankings, traffic, and leads together
How to measure domain authority well? Save the score beside referring domains and organic traffic. This shows whether link gains support real growth.
To find my domain authority, use the provider's site explorer or link research tool. To look up domain authority, enter the root domain. To find out domain authority, avoid tools that hide the data source.
Small SEO tools domain authority checks may help with a quick scan. Treat them as rough checks. Paid tools often offer better link data and history.
Domain Changes, 301s, and Rebranding
How to change domain without losing SEO? Map every old URL to its closest new URL. Then use a 301 redirect for each matching page.
A 301 tells crawlers that a page moved for good. It does not guarantee that every signal transfers. Keep the old domain active during the move.
Domain authority 301 rebranding work needs careful checks. Update internal links, canonicals, sitemaps, and key external profiles. Watch rankings and crawl errors after launch.
- Crawl the old site and save its key URLs.
- Build matching pages on the new domain.
- Map old URLs to their best new matches.
- Set one-step 301 redirects and test them.
- Submit the new sitemap and track errors.
Do not buy an old domain only for its score. Past links may be weak, unrelated, or risky. Review the domain's history before any rebrand.
Common Misconceptions About Domain Authority
Is domain authority legit? Yes, as a Moz comparison metric. It is not an official Google score.
What is domain authority and why is it important? It is a link-based benchmark. It matters when it helps you compare sites and plan better work.
What is domain authority and page authority? Domain Authority covers the full domain. Page Authority estimates the strength of one URL.
What is domain authority of a website? It is the score assigned to that domain by a chosen tool. The result can differ between tools.
What is SEO authority? It is a broad phrase for trust and strength in search. It is not one fixed metric.
What is domain SEO? It means improving a site's technical setup, content, links, and visibility. It is broader than any authority score.
Finally, do not chase a perfect number. A low score can still support strong rankings for a narrow topic. Better pages and better links beat score watching.
Monthly workflow
One hour a month, four steps
A repeatable competitor website traffic analysis workflow the marketing owner can run alone.
01
Pull and track the numbers
Open your two tools, pull the five metrics above for each competitor, and drop them into the shared spreadsheet you use to track everything. Fifteen minutes if your list has five competitors.
02
Spot the moves
Look for any metric you track that changed more than 20 percent month over month. Those are the moves worth understanding — everything else is noise your team can ignore.
03
Investigate the top move
Open the competitor's website, find the new content, links or campaigns that explain the move. Screenshot the evidence and paste it into the same spreadsheet.
04
Write five lines
Summarise for the team: what changed, why it changed, what your marketing should do about it. A five-line summary read in a stand-up beats a 20-tab dashboard nobody opens.
One hour a month, two tools and a spreadsheet — enough to track what competitors are doing and monitor how their moves compare to yours.
What goes wrong
Six ways teams waste the analysis
Every mistake here is common on a competitor analysis programme — and every one turns useful data into a report nobody reads.
Trusting one tool
A single tool's number is a modelled guess. Two tools that agree within 30 percent are worth quoting; one tool alone is not.
Tracking too many competitors
Five is the ceiling most marketing teams can actually track monthly. Ten becomes a chore, twenty becomes abandoned, and the analysis dies inside a quarter.
Chasing the absolute number
Debating whether a competitor gets 42,000 or 58,000 monthly sessions is time your marketing team will never get back. Trend and channel mix change decisions; the label does not.
Skipping the spreadsheet
Without a monthly log, no trend exists. A screenshot in Slack is not an analysis — it is a snapshot that will be forgotten in a week.
No follow-through action
If nothing in the marketing plan changes because of the analysis, the analysis is decoration. Every monthly review must end with an owner and a next step.
Comparing to giants
Benchmarking a 12-month-old SME website against the category leader tells your team nothing useful. Compare like with like or the numbers demoralise everyone.
If your competitors are pulling ahead
Move the numbers your competitors watch
Once your competitor analysis shows a rival's Similarweb curve climbing on their traffic buys, our Similarweb traffic service and managed web traffic move your own website into the same reporting bracket — with a written plan, live dashboard and SLA.
Common questions
Competitor traffic analysis, answered
What SME marketing owners and agencies actually ask when they start monitoring competitor websites.
How much traffic does my competitor get, and can I see the real number?
You cannot see the exact number — only the competitor themselves can. What you can see is a modelled estimate from Similarweb, Semrush or Ahrefs, plus the search visibility those tools track. Use two tools rather than one, and treat the trend as more reliable than the absolute figure.
How do I get competitor website traffic estimates for free?
The free tiers of Similarweb, Ubersuggest and Semrush all show a monthly traffic estimate for any public domain. It is enough to spot which competitor is growing and which is stalling — buying a paid tool only becomes worthwhile once your marketing team wants to track keyword-level movement or referring domains in detail.
Which competitor traffic tool is the most accurate?
None of them are accurate in absolute terms — each tool models traffic from different panel data, and figures routinely differ by 30 to 60 percent across tools for the same competitor. Similarweb tends to over-estimate large B2C sites, Ahrefs under-estimates them, and Semrush lands somewhere between. Trust the trend line, not the label.
How often should a marketing team monitor competitor websites?
Monthly is enough for most SMEs. A weekly cadence adds noise without signal, and a quarterly cadence misses the moves worth reacting to. One hour a month with two tools, one shared spreadsheet and a five-line summary covers what most marketing teams actually need to track.
How many competitors should I track?
Five is the practical maximum for a one-person marketing function. Split them into three direct competitors and two aspirational competitors — enough to see the shape of the market without turning the analysis into a weekly chore.
What if a competitor's website traffic estimate looks suspiciously high?
Cross-check with a second tool and monitor their referring domains. If competitors' traffic is climbing while their ranking keyword count and referring domains are flat, they may be buying traffic rather than earning it. Useful information — it tells you how much of their visible growth is defensible.
Can I get competitor website traffic data without paying for a tool?
Yes, to a limited depth. Similarweb and Ubersuggest free tiers cover the headline monthly traffic estimate. Google Trends covers branded search interest over time. Together they answer the "how much" question well enough for most SMEs — the paid tools earn their subscription when your team needs keyword-level detail every month.
How does competitor analysis feed into our own marketing plan?
Every monthly analysis should end with one decision. If a competitor gained on branded search, your marketing plan needs a brand response. If they added referring domains, your team owes itself a link push. If nothing changed, do nothing — a quiet month for your competitors is a quiet month for your plan too.
