Companies Using Impact.com

I've spent most of my career on crawl systems, first at Bing and now here, and I expected impact.com to be the cleanest affiliate tag to count. It wasn't. Our October 2026 crawl finds its Universal Tracking Tag on 10,467 live domains, the brand side of impact.com, loading from utt.impactcdn.com or d.impactradius-event.com. Only 3,982 of them match a company, 39.16% of our cleaned set against 47.95% for AWIN, so before writing anything I went looking for the reason.

How many brands sit behind 10,467 domains

I opened a random sample of 45. Twenty-one were brands on their own site. Sixteen were extra domains pointing at another brand's main site: resort.to at Westgate Resorts, truebill.com at Rocket Money, machinewashablerug.us at Ruggable, two Gatorade domains at gatorade.com. The rest were registrar pages, content sites, gambling pages on expired domains and a Flowpage link-in-bio page. Across the full set, 1,412 domains share a page title with at least nine other impact.com domains, 13.88% against 4.57% for AWIN, and only 14.9% of them match a company. No agency or platform stamps the tag on thousands of sites; the largest single group is 127 old Typepad blog addresses that now land on Network Solutions. It's many brands each owning a handful of extra domains.

Sales signal: dedupe by redirect target before you size an impact.com list. Expect it to shrink by about a third.

Growth is slowing

The chart reads 6,851 in June, 8,140 in July, 9,384 in August, 10,081 in September and 10,467 in October. Part of that is our side: the domains we crawl turn over every month, with dead sites leaving and new ones arriving, and our detection signals widen. The monthly gain has fallen from 1,289 to 386. Churn is high next to the base. 4,410 domains have dropped the tag since March 2026, 42% of today's count, though 380 of them still run it on another hostname.

"impact.com's domain count runs ahead of its brand count. A third of the domains we sampled were spare addresses pointing at a brand's main site." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales signal: size the impact.com market by matched companies, not domains. The 3,982 is the number to plan territories around.

Bigger, older and more American than AWIN

Small companies are still the largest group, 40.82% at 1 to 10 staff. But 213 companies have more than 1,000 staff, 5.59%, against 2.51% on AWIN's profile, and 20.54% were founded before 2000. The names show it: Nordstrom, Ulta Beauty, Truist, Navy Federal Credit Union, HubSpot, Getty Images, Corpay and Coursera all load the tag on their main sites. Others run it on one property. T-Mobile has it on its prepaid store, AARP on its help centre, Virgin Australia on check-in, Aman on its careers site.

Sales signal: at the enterprise end the buyer is a partnerships or performance-marketing lead with real budget. Partner-recruitment, compliance and attribution vendors will find buyers here who already pay for a platform.

A North American network

We matched 2,436 impact.com companies to the United States and 422 to the United Kingdom, nearly six to one. Canada (151) and Australia (141) follow. Germany has 51, against 1,028 on AWIN's profile. The industry mix is wider than AWIN's too. Retail leads at 10.47%, but software, internet and IT services add up to 11.68% and Financial Services plus Insurance to 6.86%. Retail and Retail Apparel together are 14.36%, against 24.35% on AWIN's profile.

Sales signal: impact.com's list suits US and Canadian outreach to subscription, software and financial brands. For European retail, use AWIN's.

Switching nets out against AWIN

Switching counts are domains since March 2026, on 30- and 90-day windows. 102 domains dropped impact.com and run AWIN, and 78 went the other way. Over the last 30 days it's 47 against 46. 25 of the 102 still run impact.com on another hostname, so the net outflow is smaller. Rakuten is the one rival impact.com gains from on balance: 59 domains in against 38 out, with 14 of the 59 still running Rakuten. CJ Affiliate is 23 in and 27 out. These are small numbers on a base of 10,467, and I wouldn't call any of them a trend.

"Brands aren't leaving impact.com for AWIN, or AWIN for impact.com, in any number. The two flows match almost domain for domain." - Mehmet Suleyman, CEO at TechnologyChecker.io

Sales signal: don't pitch impact.com's customers on a migration wave that isn't there. Rakuten's former advertisers now on impact.com are the one cohort that has recently changed network.

A paid-media stack

Across the 10,170 live impact.com domains left after removing for-sale and gambling pages, DoubleClick Floodlight runs on 42.94% and Microsoft Advertising on 42.48%. Reddit Ads is on 20.12% and Twitter Ads on 17%, against 3.98% and 3.3% on AWIN's sites. Shopify is on only 24.05%, PayPal on 22.69% and Klaviyo on 25.37%. These are brands with a media agency and a search budget, and impact.com is one more line in a performance plan.

Sales signal: attribution, consent and tag-management vendors fit this list. So do agencies that run search and paid social, because partnerships here sit inside the paid-media budget.

What it costs

impact.com's pricing page lists Starter from $30 a month, Essentials from $500, Pro from $2,500 and Enterprise on request, and says 4,000+ brands use it. On its Shopify app, Starter is the greater of $30 or 2.5% of monthly revenue, and the app is rated 4.4 stars from 202 reviews. AWIN's Shopify app showed 1.9 stars from 33 when we checked. impact.com's about page lists 21 offices and more than 1,000 employees. The 4,000+ claim and our 3,982 matched companies come from different methods, but they sit in the same range, and both are well under the 10,467 domain count.

Sales signal: the jump from Starter to Essentials is $470 a month. Brands near that line want proof that marketplace access pays for itself, and that's a conversation partner-recruitment tools can join.

Key takeaways

1. 10,467 live domains, 8th of 96, second only to AWIN among brand-side networks.

2. A third of sampled domains were aliases, so the brand count is far lower; 3,982 match a company.

3. American and enterprise-leaning: 2,436 US to 422 UK companies, and 5.59% above 1,000 staff.

4. A paid-media stack, with Floodlight and Microsoft Advertising on about 43% of domains each.

5. Switching with AWIN nets out; Rakuten is a small net source.

How to use this list

For targeting, filter impact.com domains to the US and Canada, 51 to 5,000 staff, with Floodlight or Microsoft Advertising present, then dedupe by redirect target. For outreach: "Your site runs impact.com next to Floodlight, like 42.94% of the impact.com sites we track; here's how we show which partners add sales your paid search would have won anyway." For a competitive angle, the 59 domains that moved from Rakuten since March changed network recently, which makes them the likeliest to be reviewing partner tools.
