Bulk Ad Pixel, GTM & Marketing Stack Detector

Detect ad pixels, GTM containers, and marketing tools across a list of company websites. Add your domains and get structured records with technology signals, public business emails, phone numbers, and social profiles, ready to export or use in your enrichment workflow.

Use this Actor to:

• Build prospecting lists: Find companies with Meta Pixel, Google Ads, TikTok Pixel, or LinkedIn Insight signals.
• Segment accounts by technology: Identify Shopify stores, WordPress websites, and businesses using tools such as HubSpot, Klaviyo, or Intercom.
• Enrich your CRM: Add public contact details and social links to existing company records.
• Monitor website changes: Schedule repeat runs in Apify and compare the exported results in your own workflow.

Free Apify accounts can save up to 25 domain records per run. Paid accounts have no Actor-imposed result cap; your run settings and budget still apply. See Pricing and limits for how results are counted.

How to detect ad pixels in bulk

1. Click Try for free or Start on this Actor's page and sign in to Apify.
2. Enter company domains in Company domains or website URLs. Start with a few websites and leave the other settings at their defaults.
3. Click Start, then open the run's dataset to review the results. Download JSON, CSV, or Excel, or retrieve the data through the API.

You can use the input form without writing code. For API calls or the JSON editor, this is enough to start:

{
  "domains": ["gymshark.com", "allbirds.com", "klaviyo.com"]
}

The Actor checks each homepage. By default, it also follows one discovered contact or about page on the same website when an email or phone number is missing. Each processed input produces one result record, including websites that could not be reached.

What data can you extract?

Category	Supported detections
Advertising pixels	Meta / Facebook Pixel and pixel IDs, Google Ads AW IDs, TikTok Pixel and pixel IDs, LinkedIn Insight presence
Google tags	Google Tag Manager container IDs and Google Analytics 4 measurement IDs
CRM and email marketing	HubSpot, Klaviyo, Mailchimp, ActiveCampaign, Attentive
Chat, support, and forms	Intercom, Gorgias, Zendesk, Drift, Crisp, Tawk.to, Calendly, Typeform
Analytics and testing	Hotjar, Microsoft Clarity, Segment, PostHog, Plausible, Optimizely, VWO, Bing Ads
Reviews and loyalty	Yotpo, Trustpilot, Judge.me, Okendo
CMS and website platforms	Shopify, WordPress, WooCommerce, Webflow, Wix, Squarespace, Framer, Next.js
Public business contacts	Emails and phone numbers found in page text, links, and structured contact data
Social profiles	LinkedIn, Instagram, Facebook, X / Twitter, YouTube

Detection uses the HTML returned by the website. Tags that appear only after JavaScript runs or a visitor accepts cookies may be missed. A detected tag is a prospecting signal; it does not establish active campaigns, ad spend, or ownership of an advertising account.

Input settings

Field	Default	What it does
domains	Required; the form includes sample domains	A non-empty list of public company domains or website URLs. Bare domains use HTTPS. URLs are reduced to their homepage, so paths, queries, and fragments are ignored.
extractContacts	true	Extract public emails and phone numbers. Set to false to focus on technology and social profiles.
deepContactSearch	true	Check up to one discovered contact or about page if an email or phone is missing. Requires extractContacts: true. This can increase run time.
maxConcurrency	25	Websites processed at once. Accepts integers from 1 to 100. Lower this for restrictive websites or large pages.
timeoutSecs	15	Seconds allowed for each page lookup, including connection, redirects, retries, and downloading. Accepts integers from 3 to 60. An optional contact page gets its own allowance.
proxyConfiguration	Not set	Start with direct connections and use an automatic datacenter fallback for eligible blocked responses when your account has access. See proxy options below.

Proxy options

With default settings, HTTP 403, 429, or 503 can trigger an available Apify datacenter proxy fallback. Access depends on your account and the target website. Residential proxies are enabled only when you request them.

To enable a residential fallback for difficult websites:

{
  "domains": ["gymshark.com", "allbirds.com", "klaviyo.com"],
  "timeoutSecs": 30,
  "proxyConfiguration": {
    "useApifyProxy": true,
    "apifyProxyGroups": ["RESIDENTIAL"],
    "apifyProxyCountry": "US"
  }
}

Residential traffic can increase costs and does not guarantee access. Setting useApifyProxy to true without specifying groups selects a residential fallback. To require direct connections, use "proxyConfiguration": { "useApifyProxy": false }. Custom HTTP or HTTPS proxy URLs are also supported through proxyUrls and route requests through those proxies from the start.

Output example

Each row contains the same fields, making it straightforward to filter, export, and map into other tools. The following record uses illustrative values, not measured results for the example company:

{
  "domain": "acme.com",
  "finalUrl": "https://acme.com/",
  "status": "SUCCESS",
  "httpStatusCode": 200,
  "companyTitle": "Acme",
  "cmsPlatform": "Shopify",
  "hasPaidAdsPixel": true,
  "hasMetaPixel": true,
  "metaPixelIds": ["123456789012345"],
  "hasGoogleAds": true,
  "googleAdsIds": ["AW-123456789"],
  "gtmIds": ["GTM-ABC1234"],
  "ga4Ids": ["G-ABC1234567"],
  "hasTikTokPixel": false,
  "tiktokPixelIds": [],
  "hasLinkedInInsight": false,
  "marketingTools": ["HubSpot", "Klaviyo"],
  "primaryEmail": "sales@acme.com",
  "allEmails": ["sales@acme.com"],
  "primaryPhone": "+1 (212) 555-0123",
  "allPhones": ["+1 (212) 555-0123"],
  "linkedinUrl": "https://www.linkedin.com/company/acme/",
  "instagramUrl": "",
  "facebookUrl": "",
  "twitterUrl": "",
  "youtubeUrl": "",
  "scrapedAt": "2026-10-16T12:00:00.000Z",
  "errorMessage": "",
  "htmlTruncated": false
}

How to read the results

• Advertising: hasPaidAdsPixel is true when Meta, Google Ads, TikTok, or LinkedIn signatures are found. GTM and GA4 IDs are separate fields; Bing Ads and Microsoft Clarity appear in marketingTools.
• Company details: companyTitle is the website's page title, up to 250 characters. cmsPlatform reports the primary detected CMS or framework. finalUrl shows the homepage after redirects.
• Contacts: primaryEmail is the highest-ranked public email, with company-domain addresses and business inboxes preferred. allEmails and allPhones contain unique detected values. Contacts are not checked for deliverability or phone availability.
• Missing data: Unavailable strings are "", lists are [], and an unavailable HTTP status is null. A false detection flag means the signal was not found in the analyzed HTML.
• Quality and errors: Check status, errorMessage, and htmlTruncated before using a row. scrapedAt records the extraction time in UTC.

A SUCCESS row means the Actor analyzed a usable page or page prefix. With htmlTruncated: true, part of a homepage or contact response was omitted because the page reached the size limit or a sufficiently large successful response was interrupted. Detected data is preserved, but later tags or contacts may be missing.

An ERROR row keeps the same structure and includes a short errorMessage. A failed optional contact lookup retains the successful homepage result. Check row statuses even when the overall run succeeds.

Use the results in Clay, n8n, Make, or your API

Workflow	How to use the Actor
Clay	Export CSV and match rows to your domain column, or use Clay's native Apify integration: add a Run Apify Actor enrichment column, select this Actor, and map your domain into the domains input array. Map primaryEmail, primaryPhone, cmsPlatform, and pixel flags to enrichment columns. An HTTP API workflow is also supported.
n8n	Use Apify's Run Actor operation, wait for completion, then Get Dataset Items using the returned defaultDatasetId. Filter by each row's status before updating your CRM.
Make	Run the Actor through Apify's Make integration, retrieve dataset items, and route companies by platform, detected tool, or pixel flag.
Apify API	Open this Actor's API tab for its run endpoints and examples. Start a run with your domain list, wait for completion, and read the default dataset.

Save your input as an Apify task for repeat use. Apify also provides scheduling and run monitoring, so you can refresh the same company list periodically.

Pricing and limits

The Pricing section on this Actor's Store page shows the current rate and billing model. A result is one saved domain record. A contact-page lookup enriches that record rather than creating a second result.

You are only charged the domain-enriched event fee for successful (status: "SUCCESS") domain records. Unreachable domains (status: "ERROR") are saved to the dataset for your visibility at $0 event cost. Partial records with status: "SUCCESS" are successful records for billing purposes.

For example, at $1.50 per 1,000 successful domains ($0.0015 per domain), enriching 5,000 valid company websites costs $7.50 in domain-enriched event fees. This illustrative rate does not set the live Store price. Check the Pricing tab for the current event rate, platform usage, separately priced dataset events and optional proxy charges.

Both SUCCESS and ERROR rows still count toward the 25-record Free account allowance per run.

Apify account	Result allowance per run
Free	Up to 25 saved domain records, including error and partial records. The run stops successfully at the limit.
Paid	No Actor-imposed result cap. Your charge budget, run timeout, and platform limits still apply.

The 25-record allowance is a usage cap, not a promise of free processing. The $0 error event cost refers to the domain-enriched fee. If a separate dataset-item event is priced, it applies to every saved row, including errors; check the published pricing for any such fees and proxy charges. Duplicate inputs are processed separately, so remove duplicates before starting if you want one row per unique domain.

FAQ and troubleshooting

Can it scan any website?

It can analyze public HTTP and HTTPS homepages that return HTML. Entering a product, blog, or contact URL still scans that website's homepage. Login-only pages, private network addresses, non-HTML responses, and some protected websites are unsupported.

Does it detect everything that a browser would load?

The Actor scans the returned HTML, including inline scripts, script URLs, and structured data. It does not execute JavaScript or download external tag scripts and GTM containers. Consent-controlled tags, dynamically injected tools, or server-side tracking may therefore be absent. Signatures may also occur in examples or integrations; review important detections before acting on them.

Why are emails or phone numbers missing?

The website may not publish them in accessible HTML. Leave extractContacts and deepContactSearch enabled to search one linked contact or about page when either field is missing. The Actor collects up to 50 unique emails and 25 phone numbers per record; it does not crawl every page or obtain contacts from private databases.

What should I do with blocked, timed-out, or partial results?

Result	Suggested next step
HTTP 403, 429, or 503	Retry later, reduce concurrency, or enable a suitable proxy configuration. Some websites continue to block automated access.
Timeout or interrupted download	Increase timeoutSecs, up to 60, and retry the affected domains. Large successful responses can retain detected data with htmlTruncated: true.
SUCCESS with htmlTruncated: true	Use the available fields with care. Each page has a 4 MiB decompressed HTML limit; increasing the timeout does not change that limit.
DNS or TLS error	Check that the domain exists and its HTTPS certificate is valid. Retry temporary failures after the website becomes reachable.

Interrupted successful downloads preserve partial results after at least 16 KiB of HTML has been processed. Smaller failed downloads can return ERROR. Total run time depends on website response times, redirects, optional contact lookups, and retries.

How can I get support?

Open an issue in this Actor's Issues tab. Include the affected domains, the settings you used, and a shared run so the problem can be reproduced.

How should I use extracted contacts?

Use public business data responsibly and follow the website's terms and applicable privacy and marketing rules. Verify contacts before use. This Actor is independent and is not endorsed by the platforms or technology providers it detects.
