SEMrush Free Website Stats Scraper

Scrape SEMrush public website overview metrics — authority score, monthly visits, referring domains, backlinks, and organic search traffic — for any domain. No SEMrush account, no cookies, no API key required. Uses a Chrome TLS fingerprint for fast-path domains and a Patchright anti-detect browser with residential proxy for domains behind SEMrush's reCAPTCHA v3 gate.

What this actor does

• Four modes: full, authority_only, backlinks_only, traffic_only
• Fast path: curl_cffi with Chrome TLS fingerprint parses the public overview HTML directly
• Browser fallback: Patchright (undetected Chrome) + residential proxy + Google cookie warmup for domains where the overview route returns a false 404
• reCAPTCHA v3 bypass: real Chrome binary (no HeadlessChrome leak), persistent context for cookie accumulation, 8 proxy IP rotations per domain
• Empty fields are omitted — no nulls, no sentinels

Output per domain

• type — "semrush_website_stats"
• domain — the normalized domain (e.g. custify.com)
• authorityScore — 0–100 SEMrush Authority Score
• visits + visitsText — estimated monthly visits
• organicSearchTraffic + organicSearchTrafficText — organic search visits
• referringDomains + referringDomainsText + referringDomainsChange — referring domain count + delta
• backlinks + backlinksText + backlinksChange — backlink count + delta
• asOf — data month (e.g. July 2026)
• sourceUrl — SEMrush URL the data was scraped from
• scrapedAt — UTC ISO timestamp
• notFound + reason — present only when SEMrush has no data for the domain

FAQ

Do I need a SEMrush account? No. The actor scrapes SEMrush's free public Website Traffic Checker — no login, no cookies, no API key.

Do I need a paid proxy? Yes. SEMrush gates its free checker with reCAPTCHA v3, which scores datacenter IPs as 0.0 (bot). Residential proxy is prefilled because residential IPs get higher reCAPTCHA scores.

Why does the actor take 60+ seconds for some domains? Domains that SEMrush doesn't have a public overview page for (e.g. custify.com) require the browser fallback: launching real Chrome, warming Google cookies, navigating to SEMrush, and rotating through up to 8 residential proxy IPs to find one with sufficient reCAPTCHA score. Fast-path domains (e.g. wikipedia.org) complete in under 5 seconds.

Why not full keyword/competitor data? Those require a paid SEMrush subscription and are not exposed to anonymous users. Only free-tier fields are returned.

Is this affiliated with SEMrush? No, this is a third-party actor using SEMrush's public free tools.

What's the difference between visits and organicSearchTraffic? visits is total estimated monthly traffic. organicSearchTraffic is the portion that comes from organic search results.
