How to Check Website Traffic in Bulk (CSV)

Short answer

For one site, use the free website traffic checker. For a list, paste the domains into the Similarweb Scraper and run it. You get one row per site with monthly visits, 3-month history, global and country rank, bounce rate, traffic sources, top countries, top keywords and AI chatbot traffic, plus a comparison row. Download it as CSV, Excel or JSON.

A real use case

An agency gets a list of 300 prospects from a trade show. One run sorts them by monthly visits, so sales calls the 40 biggest sites first and skips the ones with no measurable traffic. The same run pulls each site's contact email with the contacts add-on.

Step by step

Paste your domains, one per line. URLs and Similarweb links work too; duplicates are merged.
Keep the comparison row on to rank the sites by visits and growth.
Add WHOIS or contacts if you also want domain age or company emails.
Run, then export to CSV or Excel, or pull the rows through the API.

Input (paste into the JSON tab)

{
  "domains": [
    "stripe.com",
    "notion.so",
    "canva.com",
    "figma.com",
    "linear.app"
  ],
  "compareDomains": true,
  "includeContacts": false
}

What you get back

{
  "domain": "example-shop.com",
  "totalVisits": 1200000,
  "visitsChange3mPct": 12.4,
  "globalRank": 18452,
  "trafficSearchOrganic": 0.38,
  "trafficDirect": 0.31,
  "trafficSearchPaid": 0.06,
  "topCountry": "US",
  "trafficGenAi": 0.02
}

Trimmed example. Names and numbers are illustrative; your run returns real data with more fields.

Tips

Sort by visitsChange3mPct to find the fastest-growing competitors, not just the biggest.
Sites with no Similarweb estimate come back as no_data rows and are not charged.
Schedule the run monthly to build your own traffic history for a watchlist.

Plus a small per-run start fee. Apify's free plan includes monthly credit, enough to test. Check the listing for current pricing.

FAQ

How do I export Similarweb data to CSV?

Run the domains through the Similarweb Scraper and click Export on the results. CSV, Excel, JSON and HTML are all available, with one row per site.

Is this a Similarweb API alternative?

For public traffic estimates, yes. You call it over the Apify API with a list of domains and get JSON back, with no Similarweb account or API plan.

How do I compare competitors' website traffic?

Put all the competitor domains in one run and keep the comparison row on. It ranks them by monthly visits and growth and names the leader and the fastest grower.

How accurate is it?

It is Similarweb's estimate. Good for comparing sites and trends, not for exact numbers on any single site.
