Website Traffic Estimator: Similarweb Visits & Rank

Website Traffic Estimator checks a list of websites and returns public Similarweb traffic estimates for each domain: monthly visits, global and country rank, engagement, traffic sources, top countries and keywords.

Use it to compare competitors, score leads and monitor traffic. No login or API key is needed. The smallest run is one domain, such as apify.com: it costs $0.004 on the Free plan and usually finishes in under a minute.

What it does

You add domains or website URLs. For each domain the Actor returns one dataset row with the latest public Similarweb estimate:

• Traffic: monthly visits, change from the previous month and up to 3 months of visit history.
• Ranks: global rank, rank in the main country and rank in the site category.
• Engagement: bounce rate, pages per visit and average visit time.
• Traffic sources: shares of direct, search, paid, referral, social, email, display ads and AI chatbot traffic.
• Audience: top countries, top keywords with search volume, similar sites and public company facts.

It does not need a Similarweb account, login or cookies. All numbers are estimates from the public source, not data from the site's own analytics.

Good fit

• Compare the traffic of competitors or partners in one table.
• Score a lead list by monthly visits or global rank, and drop small sites with a filter.
• Watch a list of domains every week or month and see which sites grew or fell.

How it works

1. The Actor reads your list, removes www, duplicates and broken entries, and keeps one entry per domain.
2. For each domain it opens the public Similarweb website profile and reads the estimate. If you turn on the fallback, it can also try SimilarSites and the Tranco list.
3. It saves one row per domain in the dataset, a RUN_SUMMARY report and a COMPARISON table sorted by visits in the key-value store. In monitor mode it also compares each domain with your last run.

Quick start

1. Open the Input tab. The Websites list already has apify.com (box 1; the picture shows only this field).

2. Add your own domains or URLs, one per line. You can keep the other settings as they are.

3. Click Start at the bottom of the page (below the picture's frame).

4. When the run finishes, open the Output tab and choose the Traffic comparison view (box 4).

5. Check status, visits and globalRank for each domain (box 5).

   

Expected result: one row for apify.com with status: complete, about 4 million monthly visits and a global rank near 10,000 (the numbers change every month). Channel shares are filled when channelDataStatus is available; if it is unavailable, visits and rank are still there and the shares stay null.

An empty list stops the run with DOMAINS_REQUIRED. A list where every entry is broken stops with INVALID_DOMAIN. The Actor sets no fixed list size; your timeout and charge limit decide how many domains one run checks. Tested: 100 domains on the default 300-second timeout. Five of seven runs finished in 151 to 226 seconds. Two runs reached the timeout and stopped partway, after 88 and 96 domains; only the checked domains were charged. For lists above about 50 domains, set the run timeout to 600 seconds or split the list into batches. Lists above 100 domains were not tested.

Interacting settings

When	Input A	Input B	Effective behavior	Cost/result effect
You use filters	minMonthlyVisits, maxGlobalRank, countries, categoryFilter	—	All filters must match. Rows that fail are not written.	Every checked domain is charged, also filtered ones.
You monitor	mode: monitor	onlyChanges: true	Unchanged profiles are not written.	Unchanged domains are still charged.
You monitor	mode: monitor	stateName empty	The run stops before any check.	Only the start fee.
You force a route	proxyMode: direct, datacenter or residential	—	Every source request uses only that route. If it is blocked, the domain gets status: error.	Same domain check charge; no extra route charge.

Input examples

Compare a few competitors

{
  "domains": ["apify.com", "scraperapi.com", "brightdata.com"]
}

Expected behavior: the Actor checks 3 domains with the default settings. Expected output: 3 rows with visits, globalRank, channel shares and topCountries. Cost note: start fee plus 3 domain checks.

Weekly monitoring of large sites only

{
  "domains": ["apify.com", "scraperapi.com", "brightdata.com"],
  "mode": "monitor",
  "stateName": "competitors-weekly",
  "onlyChanges": true,
  "minMonthlyVisits": 100000
}

Expected behavior: the first run marks every domain new. Later runs write only profiles marked increased, decreased or changed. Expected output: rows with changeStatus and visitsChangePercent. Cost note: every checked domain is charged, also unchanged ones.

This example is trimmed and shows one row from a real run. null means the source did not publish that value. The Actor never fills a gap with a guess.

Send results to Slack or Notion

Pick your connector in the optional deliveryConnector field. After the run saves its data, the Actor posts a short summary (up to 25 rows and a link to the full dataset) there. Put a Notion page link or a Slack channel ID in deliveryTarget: in Notion every run is added on top of that one page, so your workspace does not fill up with new pages. A delivery error never fails the run and costs nothing extra. Connect a service once in Apify Console → MCP connectors.

Each summary line looks like apify.com — complete — 3,990,936 visits — global rank 9800.

Pricing

Pricing unit

You pay per event. Platform usage is included in these prices: the Actor's developer pays Apify for it, so you get no separate usage bill.

Event	When it is charged	Free plan price	Discounts
Actor start	Once per run	$0.002	same on all plans
Domain check	Each domain the Actor checks	$0.002	−10% / −20% / −30% on Bronze / Silver / Gold and higher
AI check	Each checked domain, only when includeAiTraffic is on	$0.0078	−10% / −20% / −30%

The start fee is counted per GB of run memory. This Actor runs with 256–512 MB, so it is one start fee per run.

A domain check costs the same for every result: complete, partial, not_found, error, a row removed by your filters, or an unchanged row in monitor mode. Broken entries that the Actor skips are free. An invalid input (for example, no domains) costs only the start fee. When your charge limit is reached, the run stops with stopReason: CHARGE_LIMIT and the remaining domains are not charged.

Proxy routes are included in the domain check price. There is no extra charge for a retry on another route.

Cost examples

Free plan, default settings, no AI:

Scenario	Input scope	Domain checks	Base charge	Optional charge	Stop/cap behavior
Smallest run	1 domain	1	$0.004	none	Minimum charge limit is $0.004
Competitor list	10 domains	10	$0.022	+$0.078 with AI	Stops at your charge limit
Lead list	100 domains	100	$0.202	+$0.78 with AI	Stops at your charge limit
Large list	1,000 domains	1,000	$2.002	+$7.80 with AI	Needs a longer timeout (the time is an estimate, not tested)

On the Gold plan, 1,000 domains cost $1.402. A list this large was not tested; the largest tested run is 100 domains.

Limits

• All numbers are public Similarweb estimates. They are not exact and can differ from the site's own analytics.
• The source publishes one month at a time and up to 3 months of history. The Actor does not make older history.
• Small sites often have no estimate. They return not_found.
• Some shares and names are hidden by the source. They stay null.
• Channel shares come from a second public source. If it does not answer, the row keeps visits and rank, channelDataStatus is unavailable, and RUN_SUMMARY.channelDataUnavailable counts these rows. The domain check is charged the same.
• Fallback rows from SimilarSites have no known month. Tranco gives a popularity rank, not visits.
• The source can block or slow requests. The Actor then retries on other connection routes. 100% coverage is not promised.
• The default timeout is 300 seconds. That fits about 50 domains with a safe margin. With 100 domains, five of seven test runs finished in 151 to 226 seconds and two stopped at the timeout after 88 and 96 domains. For lists above about 50 domains, set the timeout to 600 seconds in the run options or split the list into batches.
• Similarweb terms limit automated reuse of its data. Check that your use fits them.

API, export and integrations

• API: start a run with POST https://api.apify.com/v2/acts/cliqtomedia~website-traffic-estimator/runs and the input JSON. Read rows from the run's default dataset.
• Export: download the dataset as JSON, CSV, Excel, XML or HTML. Use outputFormat: flat for clean spreadsheet columns.
• Scheduling: create an Apify schedule with mode: monitor and a fixed stateName to track the same list every week.
• Webhooks / no-code: use an Apify webhook, Make, Zapier or n8n on run success, then read visits and globalRank from the dataset.
• Slack / Notion: set deliveryConnector to get a short summary after each run.

Use with AI agents (MCP)

• MCP server URL with only this Actor: https://mcp.apify.com?tools=cliqtomedia/website-traffic-estimator
• Smallest useful input: {"domains": ["apify.com"]}
• Key output fields: visits (estimated monthly visits), globalRank (1 is the biggest site), organicShare (search share, 0–1), topCountries (main countries with shares) and status (complete, partial, not_found, error).
• A one-domain run with default settings costs $0.004 on the Free plan and usually finishes in under a minute.
• Limits: a domain check is charged also for not_found and filtered rows; the default timeout is 300 seconds.

Troubleshooting

Every row says not_found

Symptom: rows have status: not_found and reason: NO_DATA. Likely reason: the sites are too small for a public estimate, or the domain is misspelled. Check: open the sourceUrl of one row in a browser. Action: fix the spelling, or turn on fallbackToOpenData to get a SimilarSites or Tranco value.

Rows have status: error

Symptom: some rows have status: error and a reason such as SOURCE_RATE_LIMIT. Likely reason: the source slowed or blocked requests. Check: read RUN_SUMMARY for stopReason and the error count. Action: run those domains again later, or lower maxConcurrency to 1–2.

The run stopped before the end of the list

Symptom: RUN_SUMMARY.stopReason is CHARGE_LIMIT or DEADLINE. Likely reason: your charge limit or the run timeout was reached. With DEADLINE after some domains were checked, the run ends as succeeded with a partial status message, and the rows it saved stay in the dataset. A DEADLINE before any domain was checked ends as failed. Check: RUN_SUMMARY.unprocessedDomains lists the domains that were not checked. They were not charged. Action: raise the maximum charge or the run timeout, then run the unprocessed domains.

Channel shares are empty

Symptom: channelDataStatus: unavailable and directShare, organicShare and the other shares are null. Likely reason: the second public source for channel shares did not answer for this domain. Check: RUN_SUMMARY.channelDataUnavailable shows how many rows have this. Action: run those domains again later. Visits and rank in the same row are still valid.

Some of my domains are missing

Symptom: fewer rows than entries in your list. Likely reason: duplicates and www copies were merged, broken entries were skipped (see RUN_SUMMARY.invalidEntries), or your filters removed rows. Action: check RUN_SUMMARY and turn off filters to see every checked domain.

FAQ

Do I need a Similarweb account?

No. The Actor reads public website profiles. No login, cookies or API key are needed.

How accurate are the visits?

They are Similarweb estimates for one month. Use them to compare sites with each other, not as exact counts. For big sites they are usually close; for small sites they are rough or missing.

Why do the shares not add up to 100%?

Shares are fractions from 0 to 1, and the source can hide some channels. Hidden shares are null. If channelDataStatus is unavailable, all shares are null for that row.

Do I pay for domains with no data?

Yes. Every checked domain is charged the same, also not_found and filtered rows. Skipped broken entries and domains left after a charge limit stop are free.

How fresh is the data?

Each row has snapshotDate, the month of the estimate. The source updates it about once a month.
