Website Contacts & Tech Stack: Emails, Phones, CMS

Website contacts and tech stack: emails, phones, social links, CMS and pixels from any website

Paste a list of websites. For each one, get the public contact details the company shows on its own site and a quick tech and health audit, in one row.

What you get

• Contacts: public emails, phone numbers, and social profile links (Facebook, Instagram, X, LinkedIn, YouTube, TikTok, Pinterest, Yelp, Threads).
• Tech stack: CMS or website builder (WordPress, Wix, Squarespace, GoDaddy Website Builder, Shopify, Webflow, FrontPage, Joomla, Drupal) and the raw generator tag.
• Analytics and ad pixels: Google Analytics 4, retired Universal Analytics, Google Tag Manager, Google Ads, Meta Pixel, LinkedIn Insight Tag, TikTok Pixel, X Pixel, Pinterest Tag, Snap Pixel, Microsoft Clarity, Microsoft Advertising UET, Hotjar, HubSpot, Matomo, Plausible, Segment.
• Site health: final URL after redirects, HTTPS status, mobile viewport, HTML page weight, load time, copyright year.
• Outdated-site score with plain reasons, for example "no viewport meta (not mobile-friendly)", "copyright 2012", "table layout", "uses Flash", "built with Microsoft FrontPage".

Polite and light. The Actor reads robots.txt, the homepage and at most 2 contact or about pages per site. No browser, no proxies, no login. $4 per 1,000 sites.

Quick start

1. Paste domains or URLs into Websites, one per line.
2. Click Start. The 3 prefilled sites finish in a few seconds.
3. Download the table as CSV or Excel and sort it by outdatedScore.

What can you do with it?

• Lead qualification: sort a list of prospects by outdated score. A site with no HTTPS, no mobile layout and a 2014 copyright is a warm lead for a redesign.
• Agency prospecting: find businesses on Wix, GoDaddy Website Builder or old WordPress, with no analytics or no Meta Pixel, and reach them at the email or phone they publish.
• Tech stack detection: see which CMS, builder, analytics and ad pixels a list of companies use. Good for market maps, competitor research and SaaS sales lists.
• Contact discovery from a company's own website: you have domains (from a CRM, a directory export, or a Google Maps scrape). Get the emails, phones and social profiles each company shows on its own site.
• CRM enrichment and cleanup: find dead sites, parked domains, and sites that redirect to a new domain.
• AI agents: call the Actor as a tool (Apify API or Apify MCP server) to answer "Which of these 50 dentists still have a site that is not mobile-friendly?".

How to use it

1. Add websites to Websites (URLs or domains), one per line: example.com, www.example.com or https://example.com/shop.
2. Click Start.
3. Download the results as JSON, CSV, Excel or HTML, or read them through the API.

The Actor always tries HTTPS first, and falls back to HTTP only when HTTPS is broken or missing (that is then reported in httpsIssue).

Input example

{
    "urls": ["https://www.allbirds.com", "https://www.lingscars.com", "https://www.spacejam.com/1996/"]
}

Field	What it does
urls	Required. Domains or http(s) URLs. Duplicates are removed. Other schemes (mailto:, file:) are ignored.

    "url": "https://www.lingscars.com/",
    "domain": "lingscars.com",
    "status": "ok",
    "httpStatus": 200,
    "title": "LINGsCARS.com: Car Leasing, Business & Personal Deals",
    "httpsOk": true,
    "httpsIssue": null,
    "hasMobileViewport": true,
    "pageWeightBytes": 137593,
    "loadTimeMs": 207,
    "copyrightYear": null,
    "tech": [],
    "generator": null,
    "analytics": ["Google Analytics 4", "Google Universal Analytics (retired)"],
    "socialLinks": {
        "facebook": "https://www.facebook.com/lingscars",
        "x": "https://x.com/LINGsCARS",
        "instagram": "https://www.instagram.com/lings_cars",
        "linkedin": "https://www.linkedin.com/company/lingscars-com",

    },
    "emails": ["sales@lingscars.com"],
    "phones": ["0191 460 9444"],
    "outdatedScore": 0,
    "isOutdated": false,
    "outdatedReasons": [],
    "pagesRead": ["https://www.lingscars.com/", "https://www.lingscars.com/about-us/"],
    "auditedAt": "2026-10-15T08:00:11.659Z"
}

The 1996 Space Jam site in the same run returns "outdatedScore": 9 with the reasons no viewport meta (not mobile-friendly), copyright 1996, table layout and font/center tags. The Allbirds store returns "tech": ["Shopify"], help@allbirds.com and a phone number.

Field notes

Field	Meaning
status	ok (audited), skipped (robots.txt disallows, or the site refuses automated visits with HTTP 401, 403 or 429), or error (does not resolve, does not load, not HTML).
url, domain	The final homepage URL after redirects, and its domain without www..
httpsOk, httpsIssue	httpsOk is true when the homepage loads over HTTPS with a valid certificate. Otherwise httpsIssue says why: certificate error, HTTPS not available, or plain HTTP.
hasMobileViewport	The homepage has a <meta name="viewport"> tag, the basic sign of a mobile-friendly layout. When the plain fetch has none, the homepage is read again as an iPhone, because many builders and m. sites send phones their own page.
pageWeightBytes, loadTimeMs	Size of the homepage HTML (uncompressed, without images and scripts) and the time to download it, redirects included.
copyrightYear	Newest year in the copyright line (for "© 2009-2016" it is 2016). null if none.
tech, generator	CMS or builder found from the generator tag, known asset paths and response headers. generator is the raw tag, which also names other tools (Elementor, Hugo, ...).
analytics	Analytics and ad pixels found in the HTML of the pages read.
emails	Emails shown on the pages read, the site's own domain first. Includes mailto: links, "name [at] domain" text and Cloudflare-protected addresses.
phones	tel: links first, then phone numbers in the visible text (North American format, or international with a + country code).
outdatedScore, outdatedReasons	Points for each sign of an old site. isOutdated is true at 3 or more (one strong sign, or two weaker ones). See the table below.
pagesRead	Every page the Actor read for this site (homepage plus up to 2 contact or about pages).

How the outdated score works

Points	Signal
4	Broken site, or a parked / for-sale domain
3	No mobile viewport, uses Flash, "under construction" or "coming soon", copyright 2014 or older
2	No HTTPS or a broken certificate, copyright 2015-2019, table layout, frames, built with an old editor (FrontPage, Dreamweaver, iWeb, Publisher, ...)
1	jQuery 1 or 2, WordPress 4 or older, Bootstrap 2 or 3, only the retired Universal Analytics, <font> / <center> tags, HTML 4 doctype, slower than 5 s, HTML over 1.5 MB

Pricing

Pay per event. You pay only for sites that were audited.

Event	Price
Site audited	$0.004 per site ($4 per 1,000)
Actor start	$0.00005 per run (Apify default)

Sites that robots.txt blocks, that refuse automated visits, or that do not load are free. Example: 500 domains with 450 audited cost $1.80. Set Max cost per run in the run options and the Actor stops at that amount.

Apify free plan: each run audits the first 10 sites, so you can try the Actor on your own list. Upgrade to a paid Apify plan to audit every site in one run.

FAQ

Where does the data come from? Only from each website itself: its robots.txt, its homepage and at most 2 of its own contact or about pages. Everything in the output is something the company publishes on its own site.

What does it not do?

• No personal data enrichment. The Actor does not look people up, guess email patterns, verify inboxes, or join data from other sources. If an address or phone number is not shown on the site, it is not in the output.
• No third-party scraping. It does not read Google, LinkedIn, Facebook, Yelp or any directory. Social links are the links the site itself shows; the Actor never opens them.
• No crawling. At most 3 pages per site. It does not follow links beyond one contact page and one about page.
• No bypassing. No proxies, no browser fingerprinting, no CAPTCHA solving. A site that says no gets status: "skipped".

Does it respect robots.txt? Yes. It reads robots.txt first and skips any page it disallows for its user agent (SiteAuditBot) or for all bots. If robots.txt returns a server error, the whole site is skipped. If a site answers HTTP 401, 403 or 429, the Actor stops there.

How fast and how polite is it? Each host gets at most 1 request per second and each request times out after 10 seconds. Different sites run in parallel, so 1,000 sites take a few minutes.

Is it safe to give it any URL? It accepts only http and https addresses on the public internet. Every redirect is checked, and requests to private, loopback or link-local addresses are refused.

Is the contact data GDPR-compliant to use? The Actor returns only what each company publishes on its own website. Some published emails can belong to a named person. You decide how you use them; follow GDPR, CAN-SPAM and the other laws that apply to you.

Why are emails or phones empty for a site? The site may show contacts only in images, in a contact form, or on a page the Actor did not read. Pages that load their content with JavaScript only (single-page apps) may also show little in the HTML.

Why was a site skipped? skipReason says why: robots.txt disallows the page, or the site refused automated visits. These sites are not charged.

Can I use it from code or an AI agent? Yes. Call it with the Apify API, the JavaScript or Python client, or the Apify MCP server. The output is flat JSON that exports cleanly to CSV. To give an AI agent this one tool, connect it to the Apify MCP server at https://mcp.apify.com?tools=brasspage/website-contact-tech-audit.
