- 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.

How to Use a Domain Authority Checker to Compare Sites
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.
What Domain Authority Tells You
A domain authority checker estimates how well a website may rank in search results. Moz created Domain Authority, or DA, as a score from 1 to 100. The score predicts ranking potential, not guaranteed traffic or sales.
DA is a comparative SEO metric. A score of 40 may look strong in one niche. The same score may look weak in a crowded market. Use it to compare similar sites, not to judge a site in isolation.
Moz explains the metric in its guide to Domain Authority. The score helps teams study website strength. It should support wider checks, such as traffic, content quality, and sales results.
How Domain Authority Is Measured
Backlinks play a central role in domain authority. A backlink is a link from one site to another. Search tools study the number, quality, and spread of these links.
A link from a trusted, relevant site can carry more value than many weak links. Tools also check linking domains, anchor text, and signs of spam. Their data may differ because each tool has its own index and formula.
Moz reports DA. Ahrefs reports Domain Rating, or DR. Semrush reports Authority Score. These scores are useful for trend checks, but they are not interchangeable.
Ahrefs describes its own measure in its guide to Domain Rating. Treat each score as a tool-specific estimate. Do not convert one score into another with a fixed rule.
Why These Scores Matter
A higher authority score often matches stronger search performance. This link is not direct proof of cause. Strong sites often have better content, more links, and greater brand trust.
Use a checker to set a useful benchmark. Compare your site with three to five close rivals. Look at pages that rank for the same topics. Then study the gap in links, content, and site coverage.
- Find competitors with stronger backlink profiles
- Spot pages that attract links in your niche
- Set a baseline before a link building campaign
- Track broad progress over several months
Scores matter most within the same niche. A local plumber should compare with other plumbing firms. A large news site sets a poor benchmark for that business.
Top Domain Authority Checker Tools
The best domain authority checker depends on your goal, budget, and preferred data set. Moz fits users who want the original DA metric. Ahrefs fits teams that want strong link data and DR. Semrush fits wider SEO work with an authority score.
Free tools can still give useful insight. They may limit daily checks, saved reports, or link details. Check the provider before entering a large list of domains. Some free pages also use old or limited data.
| Tool | Main score | Best use |
|---|---|---|
| Moz | Domain Authority | Checking the standard DA metric |
| Ahrefs | Domain Rating | Reviewing links and referring domains |
| Semrush | Authority Score | Combining authority with wider SEO checks |
A domain authority checker online can suit a quick review. A paid platform may suit regular audits. A bulk domain authority checker tool is useful when you need to compare many sites.
How to Use a Domain Authority Checker
Start with one tool and record the date. Scores can change when a provider updates its index. Keep the same tool when tracking progress over time.
- Open a trusted domain authority checker tool.
- Enter your full domain without extra page paths.
- Record the score, linking domains, and top linked pages.
- Repeat the check for three to five close competitors.
- Compare the gaps and save useful link prospects.
Use a bulk domain authority checker when you have a long prospect list. Remove duplicate domains first. Then sort results by relevance, score, and link quality.
Do not chase a high number alone. Visit each prospect and check its topic, audience, and recent content. A relevant site with a modest score may beat a broad site with little topical fit.
Free domain authority checker tools work well for a first pass. Use deeper link data when you need to plan outreach. This keeps early research fast and low cost.
How to Read Domain Authority Scores
DA uses a 1 to 100 scale. New sites often start near the low end. Growth becomes harder as a site gains more authority.
There is no universal score that makes a site strong. A DA of 25 may compete well for narrow local terms. A national finance site may need a far higher score.
- Compare sites in the same market and country
- Check the score beside ranking pages
- Review referring domains, not just total links
- Watch trends instead of one isolated result
A sudden rise may follow a new set of links. A sudden fall may follow lost links or a data update. Check the backlink profile before changing your whole SEO plan.
Also review page-level strength. A strong domain does not make every page strong. Useful content and good internal links still matter.
Ways to Improve Your Domain Authority
Improving domain authority usually means earning better backlinks. Start by making pages that solve a clear problem. Original data, useful guides, tools, and local resources can attract natural links.
Next, find link gaps among competing sites. List pages that link to two or more rivals. Those sites may offer a sound outreach target. Check fit before sending a request.
- Publish research with clear facts and fresh findings
- Build helpful pages for narrow search needs
- Ask partners to cite useful resources
- Recover links that point to broken pages
- Remove or disavow harmful links only with care
Link quality matters more than raw volume. Ten useful links from trusted sites can beat hundreds of weak links. Avoid paid link schemes, link farms, and mass guest post offers.
Track new referring domains, lost links, rankings, and leads each month. DA may rise slowly, even when your SEO work helps. Keep the score as one signal within a wider growth plan.
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.
