How to check competitor website traffic: 6 ways

You cannot see a competitor's real visits. Only their analytics account knows that. What you can do is check competitor website traffic estimates from four free sources in about ten minutes, and if you read them correctly they tell you who is bigger, who is growing and where the visits come from.

The short version: Similarweb's free site page for total visits, Semrush's or Ahrefs' free checker for search traffic, Google Trends for brand demand. Use the same tool for every competitor, and trust the direction more than the digits.

Prices below were read from each vendor's own pricing page on 4 October 2026.

How to check competitor website traffic in ten minutes

1. Open similarweb.com/website/theirdomain.com. Note total visits for the last three months and the top countries. It is the only free number that tries to count every channel.
2. Run the domain through Semrush's free Website Traffic Checker at semrush.com/website. Its own FAQ says you can use it once a day without an account. Note total visits and organic traffic.
3. Run it through Ahrefs' free Website Traffic Checker at ahrefs.com/traffic-checker. This one estimates search traffic only.
4. Put their brand name and yours into Google Trends. This shows how many people look for them by name, relative to you.
5. Do steps 1 to 4 for your own domain. You know your real number from your analytics, so this tells you how far off each tool is for a site like yours.

Step 5 is the one everyone skips and the one that makes the rest usable. Write one row per competitor, date the sheet, and you have a baseline.

What each number actually measures

The commonest mistake is comparing figures that measure different things. Similarweb's "visits" and Ahrefs' "organic traffic" are not two estimates of the same quantity.

Similarweb, for total visits

The free page for any domain shows total visits for the last three months, engagement (bounce rate, pages per visit, visit time), top countries and the top three marketing channels. The full channel breakdown needs a trial.

Two things to know. Several sections on the free page, including countries and traffic sources, are labelled desktop only. And the page carries the line "Showing Similarweb estimated data", with an invitation for site owners to connect Google Analytics, so a few sites show validated numbers and most do not.

Paid access goes through sales. The only figure on Similarweb's pricing page is "from $125/mo" in the page description. Our Similarweb alternatives page covers what else does the job.

Semrush and Ahrefs, for search traffic

Search traffic estimates work roughly like this: take every keyword a site ranks for, multiply the search volume by the share of clicks expected at that position, and add it up.

That makes them blind to everything that is not search. They also cannot see when a results page sends fewer clicks than the model assumes, for example when an AI Overview answers the question before anyone clicks.

The free checkers are enough for occasional lookups. Paid plans start at $139 a month for Semrush's SEO plan and $129 a month for Ahrefs Lite. Semrush's total-visits data with channel mix sits in a separate Traffic & Market toolkit, listed at $289 a month billed annually.

Google Trends, for demand

Trends does not count visits. It shows how often people search for a brand, relative to the others you compare it with, which is the closest free signal to brand strength. The Google Trends comparison guide covers the settings that make it reliable.

Public signals, for growth

None of these are traffic, and all of them move when a business grows:

• Job posts. A company hiring five salespeople expects demand. The headcount guide shows where to find them.
• Review count growth. Google reviews added per month, compared with last year, tracks customer volume within one business.
• Claims over time. "Trusted by 2,000 teams" on last year's homepage and "5,000 teams" today is a growth rate. The Wayback Machine guide shows how to pull the old versions.

How far to trust the numbers

There is no honest single accuracy figure for any of these tools, because the error depends on the site. Four working rules instead.

Direction beats level. Three months moving the same way in one tool is more trustworthy than any single month.

Ratios beat absolutes. If two competitors differ by five times in the same tool, they are different sizes. If they differ by 20%, you cannot tell them apart.

Small sites are noise. Semrush's own FAQ says "very small or new websites may not have enough public data to generate a reliable estimate". At a few thousand visits a month, three keywords moving can swing the figure by half.

Calibrate on yourself. If a tool says you get 9,000 visits and your analytics says 4,000, assume it is generous with sites like yours too. Crude, and much better than taking the number at face value.

There is more on where the errors come from in how accurate traffic estimates are.

Comparing competitors fairly

Same tool, same month, same country. Mixing a Similarweb figure for one competitor with an Ahrefs figure for another is meaningless.

Check the country split. Similarweb's free page for semrush.com, checked on 4 October 2026, puts India second in its desktop traffic at 11.7%. If you only sell in the UK, a global visit count flatters any competitor with a big audience elsewhere.

Strip out the product. For software companies, logged-in customers using app.competitor.com can dwarf marketing traffic. Semrush's checker lets you choose Domain, Exact URL, Subfolder or Subdomain, so compare the marketing site, or just the /blog/ folder, rather than the whole domain.

Separate brand from non-brand. A competitor whose organic traffic is mostly people searching their own name is not beating you at SEO. They have a brand, which is a different problem with a different fix. Most SEO tools let you filter branded keywords out of the organic report.

What the numbers mean for small and local sites

For a local business, a competitor with 800 visits a month and one with 2,000 may show as the same, or as zero. This is where every tool is weakest.

Better proxies at that size: how many Google reviews they collect a month, whether they run ads in the public ad libraries, and how many service or location pages their sitemap lists. The local competitor monitoring guide covers the hour-a-month version.

Keeping an eye on it

A monthly row per competitor is enough for most teams. After six months, the trend is worth far more than the first reading, and the traffic sources guide shows how to split it by channel.

If you want the search side done for you, Figo records each tracked competitor's Google keyword positions and estimated organic traffic every week, next to their new pages, ads and reviews. Plans start at $49 a month for three competitors. Ours, so judge accordingly.

Those figures are estimates from search data, not visits, and Figo does not estimate total traffic across all channels or market share. If that is the number your board asks for, Similarweb is the right tool and we are not.
