Crazy Egg
Crazy Egg is a heatmap tool. It records where visitors click, how far down a page they scroll and where they move, then draws the result as a coloured overlay on a screenshot of the page so that whoever is editing the layout can see which parts get used. This index classifies it as tracking. It was detected on 59 of 5,294 sites in this snapshot, 1.1% of them, which is 74th of 88 by reach, and its distinguishing figure is not how many sites it is on but when things start happening on them.
First contact at 927 ms, the eighth-latest of 88 companies
On the median Crazy Egg site, the first third-party request left the browser at 927 ms. Order the 88 companies in this index from the latest median first contact to the earliest and Crazy Egg sits eighth. On most entities here the first outside party is contacted well before that. A later median means the page renders more of itself before reaching outward, which can come from deferred script loading, from a slower first paint, or from a page that simply has fewer things queued at the top of the document.
A lower early-contact share than most
52 of the 59 sites saw a company arrive before the banner had been answered. At 88.1% that ranks 74th of the 88 companies in this index, near the low end. Seven sites recorded nothing arriving inside that window. The median site contacted 6 companies inside it and 1 after it closed, so on a typical Crazy Egg site something in the page's third-party set still arrives after the window has closed.
A public-sector cluster
digitalgov.gov, a hostname that appears on United States federal sites, was present on 12 of Crazy Egg's 59 sites, 20.3% of them, and siteimproveanalytics.com on 8 (13.6%). The example set matches: fda.gov contacted 5 companies with 4 inside the consent window, epa.gov contacted 5 with 4 at 1,325 ms, and npr.org contacted 15 with 6 inside it. Government and public media are a meaningful share of where this tool was found, alongside oecd.org and pewresearch.org.
The two extremes in its example set
washington.edu contacted 17 companies with none of them inside the consent window and a first contact at 5,547 ms, the latest in this example set. pewresearch.org is its mirror image: 9 companies, all 9 inside the window, first contact at 173 ms, which is the earliest on any Crazy Egg site in this snapshot. Between them sit independent.co.uk with 14 companies and all 14 inside the window, marca.com with 17 and 12 inside it, ipify.org with 13 and 11, and cloudinary.com with 6 and 6 at 260 ms.
Fifteen of 59 sites carried a banner
The crawl identified a consent tool on 15 of the 59 sites. Alongside Crazy Egg it saw OneTrust on 5 and an IAB TCF consent tool on 5, then Cookiebot on 2, and CookieYes, Osano and Iubenda on 1 each. They are counted per tool, and since one page can hold two banners they are not guaranteed to be shares of the 15. opendns.com and namecheap.com both sit in the example set behind OneTrust, with first contact at 1,013 ms and 1,066 ms. Six different consent products across fifteen sites is a wide spread for a set this small, which fits a footprint that stretches from federal agencies to Spanish and British newspapers.
What else is on the page
Google was present on 54 of the 59 sites, 91.5%. After digitalgov.gov, the co-presence list runs Meta on 10 sites, jsDelivr on 10, Adobe Fonts on 10, Cloudflare on 9, LinkedIn on 9, siteimproveanalytics.com on 8 and Microsoft Clarity on 7. Two behaviour-recording tools on the same page, a heatmap product and a session replay product, is common enough here to be worth checking for on a site you own; MurmStack reports both when they are present.
