The LinkedIn entry in this index is not the social network itself. It is the advertising tag a company installs on its own website so that LinkedIn can tell which ad clicks turned into a demo request, and so the company can show later ads to people who visited but did not convert. You meet it on the marketing site of a software vendor, not on a shop or a newspaper. The index found it on 219 of the 5,294 sites measured, 4.1% of them, ranking 17th of the 88 companies broken out here.
The densest tracker count in this index bar three
The median site carrying the LinkedIn tag runs 5 companies classified as tracking. Ranked against the other 87 companies in this index on that measure, it comes 4th of 88 — near the top of the table, though not at it.
The rest of the page scales with it. The median site reaches 13 outside companies over 55 third-party requests, ranking 21st and 25th of the 88. These are not the heaviest pages measured, and they are not close to the lightest either. What distinguishes them is the ratio: a page with 13 companies of which 5 are tracking is a page where a large fraction of the third parties are there to follow the visitor rather than to serve a file.
A stack that repeats itself
Google is present on 214 of the 219 sites, 97.7%. Meta follows on 32.4% and its pixel on 25.1%. Then comes the part that gives the group its shape: HubSpot on 26% of the sites, and four separate HubSpot-operated hostnames — for banners, analytics, ad pixels and forms — each on between 17.8% and 24.7%. Cloudflare is on 16.4% and jsDelivr on 15.5%.
Read down that list and the buyer is obvious. This is a business-to-business marketing department's setup: a customer relationship platform with its own form and banner hosts, the three big advertising networks, and a content delivery network underneath. The LinkedIn tag is one component of a kit that tends to be bought together, which is why finding it predicts the rest of the list so well.
200 of 219 had contact before the banner could be answered
Early contact occurred on 200 of the 219 sites, 91.3%. Of the 88 companies here that ranks 63rd — a lower share than most entries in this index, and still nine sites in ten.
The median site made its first third-party contact 749 ms into the load, ranking 29th of the 88, and the earliest anywhere in the group was 115 ms. On the median site, 9 companies had been reached inside the consent window.
Two more arrive after the window closes
On the median site carrying this tag, 2 further companies appear after the consent window has closed. That is the index's own measure of what arrives late — a separate figure, not the gap between two other medians.
A non-zero value means the page is still recruiting third parties after the window has passed rather than having finished by then. That is consistent with what these sites are: forms, chat widgets and retargeting pixels that fire on interaction or after the main content settles, rather than a single burst in the document head.
The spread, and where the banners are
datadoghq.com is the heaviest example published for this group at 24 companies, 22 of them inside the window, with first contact at 535 ms and no banner detected. kaspersky.com reaches 22 with 3 inside the window. hotjar.com reaches 18 with all 18 inside it behind a OneTrust banner, and trendmicro.com 18 with 13 inside it, also behind OneTrust. applovin.com reaches 18 with 16 inside the window. inmobi.com, skyhigh.cloud and mediatek.com each reach 14 to 16; mediatek.com is the group's counter-example, with none of its 14 inside the window and first contact at 2,045 ms. Lighter examples sit at webex.com and oxylabs.io with 12, amplitude.com with 10, and optimizely.com with 6.
A consent tool was detected on 77 of the 219 sites. OneTrust was seen on 47 of them, an IAB TCF consent tool on 13, Cookiebot on 8, Osano and CookieYes on 3 each and Klaro on 1 — counts of sites where each was seen alongside the others, not a division of the 77, since a site can carry more than one banner. The dominance of OneTrust in that list is the same signal as the HubSpot cluster: enterprise software buys enterprise compliance software.

The six most common are listed. The remaining 2 of 77 sites with a banner carry something outside that six. One tool is recorded per site, so these counts never overlap.

Questions
Is this LinkedIn the website?
No. This entry counts sites that load LinkedIn's advertising tag on their own pages, which is what a visitor's browser contacts during the load. It is classified in this index under Advertising and as tracking.
How many sites carry LinkedIn?
219 of the 5,294 measured, 4.1% of the corpus, ranking 17th of the 88 companies reported here.
Why do these pages have so many tracking companies?
The median is 5, the 4th-highest of the 88 companies in this index. The tag is bought as part of a business-to-business marketing stack — Google is on 97.7% of the same sites and HubSpot on 26% — and each component brings its own measurement.
What does it mean that two companies arrive after the consent window?
It means the median page is not finished making third-party contact when the window closes. Forms, chat widgets and retargeting pixels commonly load later in a page than analytics does, and the index measures that late arrival directly rather than inferring it from other medians.
Does the index show which company was contacted first?
No. It records how many companies were reached inside the consent window per site and when the first contact of any kind happened — a median of 749 ms here — not the identity or order of the parties in that window.
