Companies Using Pinterest Tag

Marketing is my job at TechnologyChecker.io, and the Pinterest Tag is the signal I'd check first to see whether a brand buys Pinterest ads or only posts pins. Our September 2026 crawl finds it on 331,190 domains, and 124,033 of them match a company record. That puts it 4th in Ad Networks with 6.35% of the category, 10,710 domains ahead of Twitter Ads. The Pin It button and Pinterest site verification are a different product, covered on our Pinterest profile.

Two signals, one headline

We count a domain when its page sends the tag's event beacon to ct.pinterest.com, the call Pinterest uses to record a page visit or a purchase. A second signal looks for the tag's code itself: the pintrk function and its script from s.pinimg.com. The two mostly agree. 147,112 of the 169,497 domains with the code also fired the beacon, 86.8%. That leaves 22,385 domains with the tag installed but no beacon when we crawled them, which is what a tag held back by a cookie banner, or one reduced to its fallback image pixel, looks like. We state them here and keep them out of the headline; counting both would give 360,739. Our post on technology detection methods covers how network-request signals are matched.

When we reloaded 40 random detected sites in a browser, 28 of the 38 that loaded fired the beacon on the first visit. The 10 that stayed silent fit consent gating, or a tag that fires only on later pages.

Sales Signal: A detection means the company has a Pinterest Ads account with conversion tracking set up. That says far more about ad spend than a Pin It button or a Pinterest link in the footer.

59% of it is Shopify, and merchants can't see it

200,049 of the 338,351 live Pinterest Tag domains run Shopify, 59.12%. The more telling number is how they show up: 191,247 domains fire the beacon with no visible tag code, and 99.1% of those are Shopify stores. Pinterest recommends its Pinterest app for Shopify over pasting code into a theme, and the app installs the tag and the Conversions API, running the tag inside Shopify's sandboxed pixel. Among domains where we see both the code and the beacon, only 7.1% are on Shopify.

So a Shopify merchant looking for the Pinterest Tag in their theme won't find it. Neither will an audit that searches page source.

Sales Signal: On a Shopify prospect, the tag tells you the Pinterest app is connected. Installation is solved, so pitch catalogue and shopping-feed quality.

Growth trajectory and the churn that isn't

The chart runs from 259,926 domains in June 2026 to 331,190 in September, and 52,805 of that rise lands between June and July. I'd use the September count and ignore the climb: the domains we crawl turn over every month, with dead sites dropping out and newly found ones added, and our detection signals widened over the same weeks.

The churn number needs a louder warning. 168,332 domains have dropped a detection since March 2026, which would be a startling exodus if it were real. On live domains the tag shows up on only 90.1% of our scans, and 43.6% of the dropped domains were seen only once. Sites that dropped it are 1.49 times as likely to run a consent-management platform (33.05% against 22.2%). That is a tag waiting for a cookie banner.

"Read the Pinterest Tag's churn as advertisers leaving and you'd conclude nearly a third quit in six months. They didn't. The tag waits for consent, and a crawler that never clicks accept sees it come and go." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales Signal: If a site with a consent banner shows no Pinterest Tag, check again after accepting cookies before you cross it off.

Customer profile

69.43% of matched companies have 1 to 10 employees, another 20.35% have 11 to 50, and 69.44% were founded in 2010 or later. Put that next to Shopify on 59.12% and the typical Pinterest Tag customer is a young direct-to-consumer store.

The enterprise tail is real: 1,360 matched companies have more than 1,000 staff and 264 more than 10,000. In those, the tag often sits on a side site: Walgreens runs it on photo.walgreens.com, its photo-printing store, and Starbucks on athome.starbucks.com; Ecolab and Baptist Health run it on recruiting sites, jobs.ecolab.com and careers.baptisthealth.net. Two of the large names also appear in Pinterest's own published success stories: Starbucks, for a fall campaign in Canada, and J.C. Penney, for Top of Search ads.

Sales Signal: In large companies the Pinterest Tag often belongs to one product line or to recruitment marketing. Find the team that owns the detection host before you pitch the brand.

Industry and geographic concentration

The three retail labels (Retail, Retail Apparel and Fashion, Retail Luxury Goods and Jewelry) add up to 27.08% of matched companies. Insurance is third at 3.03%, and much of it is one advertiser's network: between 5,600 and 6,000 State Farm agent microsites share an identical tag setup, and each agent's site counts once. That fleet is roughly 1.8% of the whole base.

The United States leads with 59,934 matched companies, 5.3 times the United Kingdom's 11,257, with Canada (7,019) and Australia (6,584) next. Brazil is sixth at 3,445 but heavy at the top: 7 of the 50 largest named companies are Brazilian, including Magazine Luiza, Riachuelo and Vale.

Sales Signal: Take the State Farm microsites out before you size an insurance segment; what's left is a much smaller vertical. In Brazil the tag turns up on large retailers and telecoms, a warmer enterprise market than sixth place suggests.

No switching table, on purpose

We didn't evaluate migration for this tag, and I wouldn't trust a corridor if we had. The churn is consent flicker, so a "switch" would mostly be a banner hiding one tag on one visit. Ad tags also don't replace each other: the Facebook Pixel runs on 81.65% of Pinterest Tag domains, since each network an advertiser buys from needs its own tag.

"A Pinterest advertiser adds Meta, TikTok or Snapchat. It doesn't trade one tag for another, so the useful question is which networks it hasn't added yet." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales Signal: Pitch additions. A server-side Conversions API setup is the obvious one, because it keeps counting conversions when the browser tag is blocked or waiting for consent.

Technology ecosystem

Beyond the Facebook Pixel, the TikTok Pixel runs on 24.83% of Pinterest Tag domains, the LinkedIn Insight Tag on 14.85%, the Quora Pixel on 11.53% and Snapchat's pixel on only 4.02%. Klaviyo sits on 23.11%, Judge.me reviews on 16.59% and Microsoft Clarity on 26.29%. Percentages are shares of the 338,351 live domains in our current crawl.

Sales Signal: 95.98% of these sites carry no Snapchat pixel, which makes Snapchat an obvious add for an agency already running someone's Pinterest account.

Key takeaways

1. Rank: 4th in Ad Networks with 6.35%, on 331,190 domains.

2. What we count: the ct.pinterest.com beacon; 22,385 more domains have the code but sent no beacon.

3. Typical account: a small Shopify store founded after 2010, in retail or fashion, running Pinterest's app.

4. The fleet: 5,600 to 6,000 State Farm agent sites inflate Insurance.

5. The churn: 168,332 dropped detections, mostly consent flicker.

Sales applications

Outreach angle: Lead with consent. An advertiser whose Pinterest Tag waits for a cookie banner loses conversions from visitors who never click accept, which makes a server-side setup an easy first conversation.

Targeting: On TechnologyChecker.io, pull Pinterest Tag sites in Retail Apparel and Fashion or Retail Luxury Goods and Jewelry, and drop the State Farm microsites from any insurance list before you count it.

Competitive angle: 254,350 of the 338,351 live Pinterest Tag sites run no TikTok Pixel. Those advertisers already pay for visual social and haven't added TikTok.

The figures on this page come from TechnologyChecker.io's September 2026 crawl, refreshed monthly: 331,190 domains running the Pinterest Tag, 124,033 of them matched to company records.
