TikTok & Kwai Ads Checker — Detect Advertisers by Domain 🎯

Feed it your company list — get back, for every company, whether they run TikTok ads, Kwai ads, Meta ads or Google Ads, with the actual pixel IDs as evidence. Works for companies in any country (Brazil, US, LATAM, Europe, APAC…), because it doesn't search TikTok's ad archive — it detects the ad pixels installed on each company's own website, including the ones hidden inside Google Tag Manager containers.

Why use this checker

• It answers the question ad libraries can't. TikTok only publishes an ad library for the EU/EEA + UK + Turkey. Ads delivered in Brazil, the US, or anywhere else are not publicly searchable — with any tool. Kwai has no public ad archive at all. The pixel on the advertiser's own site is the reliable, region-independent signal.
• No more name matching. Ad-library search actors try to match your company names against registered legal entities ("S.F. TRADING S.R.L.") and fail. This checker joins on the one identifier you already have: the domain.
• GTM-aware detection. On corporate sites, most ad pixels are injected at runtime by Google Tag Manager and never appear in the raw HTML. The checker downloads and scans each site's GTM containers — in real-world testing, ~85% of confirmed TikTok advertisers were only detectable this way.
• Bot-walls handled for you. Three independent HTTP stacks with real-browser TLS fingerprints, escalating through built-in residential proxies at no extra cost and zero configuration.
• Kwai included. The only Store actor that detects Kwai for Business pixels — essential for Brazil and LATAM prospecting.

What it does

1. You paste a list of company websites — bare domains, hosts or full URLs, straight from a CRM/CSV export.
2. Each site is fetched with an escalating chain: direct → residential proxy → alternate HTTP stack.
3. The HTML plus up to 3 linked Google Tag Manager containers are scanned for ad-network signatures.
4. You get one row per company: verdict per network (yes / no_signal / unknown), pixel IDs, detection path, and fetch diagnostics.

Use cases

• Agency prospecting — qualify leads by whether they already buy short-video ads (they have budget) or don't yet (they need you).
• CRM enrichment — fill an "Ad Networks Used" column across your whole database.
• Competitor & market monitoring — track which players in a vertical are on TikTok/Kwai and when new pixels appear.
• Market sizing — measure TikTok-ads adoption across an industry list.
• Sales triggers — a freshly installed pixel is a buying signal for creative, UGC and performance services.

Input configuration

{
    "companies": ["kabum.com.br", "https://www.alura.com.br", "acme.com"],
    "detectTikTok": true,
    "detectKwai": true,
    "detectMeta": true,
    "detectGoogleAds": true,
    "scanGtmContainers": true,
    "maxConcurrency": 10
}

• companies — one entry per company; messy exports are fine (mixed domains/URLs, duplicates are deduped by host).
• detect* — switch individual networks off if you only pay attention to some.
• scanGtmContainers — leave on; it's where most detections come from.

Key output fields

Field	Meaning
runsTikTokAds / runsKwaiAds	yes = pixel found (IDs in …PixelIds); no_signal = site reachable, no pixel; unknown = site couldn't be fetched
…DetectedVia	page = pixel inline in the HTML, gtm = found inside a Google Tag Manager container
metaPixel, googleAdsDetected	Boolean bonus detections for Meta and Google Ads

fetchedVia	Which rung succeeded: direct, residential-proxy, residential-proxy-got

FAQ

Is a pixel proof that they're running ads right now? It's strong evidence of an active or recent ad program: pixels are installed to track paid campaigns, and pixel IDs come from live ad accounts. It can't distinguish "campaign live this minute" from "campaign paused last month" — treat yes as "this company buys (or very recently bought) ads on this network."

Can a company run TikTok ads without a detectable pixel? Yes, two gaps: server-side-only tracking (Events API without the JS pixel) and pure branding campaigns with no conversion tracking. Both are rare among SMB/e-commerce/performance advertisers. no_signal means "no evidence," not "provably zero ads."

What about unknown / blocked rows? Some corporate sites sit behind aggressive WAFs that block all plain HTTP clients. The checker escalates through three stacks and residential proxies, and retries blocked sites up to two extra times on fresh proxy exit IPs; the few walls that survive all of that are honestly reported as unknown instead of guessed.

Does it work for US / Brazil / LATAM companies? Yes — that's the point. It reads each company's own website, so it works identically for every country, unlike TikTok's ad library (EU/UK/TR only).

Do you support other tag managers (Tealium, Segment)? GTM is scanned today and covers the overwhelming majority of sites. Other tag managers are on the roadmap — open an issue if you need one.

How fresh are the results? Every run fetches the sites live at run time.
