Reddit Pixel
The Reddit Pixel is the conversion tag an advertiser puts on its own website so that Reddit can connect an ad someone saw on Reddit to a signup they completed later somewhere else. It has nothing to do with browsing Reddit; you meet it on the marketing site of a company that buys ads there. This index classifies it under Advertising and as tracking, and found it on 58 of the 5,294 sites measured, 1.1% of them — 77th of the 88 companies broken out here, which makes it one of the less-encountered entries in the set.
Rarely seen, and rarely behind a banner
A consent tool was detected on 16 of the 58 sites — a bit over a quarter of the group. OneTrust was seen on 10 of them, Cookiebot and Usercentrics on 2 each, and an IAB TCF consent tool and Iubenda on 1 each. Those are counts of sites where each tool was seen alongside the others rather than slices of the 16, since a site can carry more than one.
The other 42 sites showed no detected banner. That fits the group: an advertiser buying Reddit inventory is usually selling to a North American audience first, and a site built for that audience often has no European-facing banner to show.
Five tracking companies on the median page
The median site carrying this pixel reaches 13 outside companies over 54 third-party requests, with 5 of those classified as tracking. That tracker count ranks 8th of the 88 companies in this index, near the top of the table, while the company and request counts rank 24th and 26th.
So the pages are mid-weight overall but dense in the specific sense that matters: a large share of what they load is there to follow the visitor. That is what a performance-marketing setup looks like when several ad platforms are being measured at once.
Late to the first contact
The median site made its first third-party contact 870 ms into the load. Among the 88 companies in this index that ranks 10th, which puts these pages near the slow end of the field — they wait longer than most before reaching an outside company.
That delay shows up in the early-contact share. Early contact occurred on 51 of the 58 sites, 87.9%, which ranks 76th of 88 — one of the lower shares in this index. It is still seven sites in eight. The earliest first contact anywhere in the group was 125 ms, and on the median site 8 companies had been reached inside the consent window.
The two slowest examples reached nothing inside the window
usps.com is the heaviest example published for this group at 20 outside companies, with first contact at 2,623 ms and none of the 20 inside the consent window. mediatek.com is next at 14 companies with first contact at 2,045 ms, again with none inside the window. Both illustrate the mechanism directly: a page that does not reach anyone for two seconds has nothing to report inside a window that has already passed.
The fast end of the sample behaves the opposite way, and it is where the developer-facing sites cluster. onesignal.com reached 12 companies with all 12 inside the window at 178 ms, curseforge.com 13 with all 13 at 226 ms, character.ai 8 with all 8 at 351 ms behind an IAB TCF consent tool, tailscale.com 11 with all 11 at 407 ms, cursor.sh 11 with all 11 at 834 ms. In between sit oxylabs.io and plesk.com, both at 12 companies with only 2 inside the window, zendesk.com at 8 with 3, adp.com at 11 with 6, and optimizely.com at 6 with 5.
Half of these sites also run the LinkedIn tag
Google is present on 54 of the 58 sites, 93.1%, and a second Reddit-operated host on 89.7%. Then comes the figure that describes the group: LinkedIn's advertising tag is on 50% of them. Meta follows at 25.9% and its pixel at 22.4%, Microsoft Ads and HubSpot at 17.2% each, Microsoft at 15.5%.
Half of a group sharing one other ad platform is a strong signal about who is buying. Reddit and LinkedIn sell to overlapping audiences — technical and professional buyers who are hard to reach on general consumer inventory — and the sites here are mostly developer tools and business software, which is exactly the advertiser that runs both. After the consent window closes, the median site adds 1 further company.

Questions
Does the Reddit Pixel mean a site is affiliated with Reddit?
No. It means the site buys or has bought advertising on Reddit and installed the tag that measures which of those ads led to signups. The tag is the advertiser's decision, made on the advertiser's own website.
Why do so few of these sites show a consent banner?
16 of the 58 did. The group is dominated by North-American-facing business and developer software, where a European-style banner is often not deployed at all.
Why is the early-contact share lower here than elsewhere?
Because these pages start later. The median first contact is 870 ms, which ranks 10th of the 88 companies in this index and puts the group near the slow end. Even so, 51 of the 58 sites had at least one company contacted inside the consent window.
How dense are these pages with trackers?
The median site runs 5 companies classified as tracking out of 13 outside companies in total. That tracker count ranks 8th of the 88 companies reported here, near the top of the table.
How many sites carry Reddit Pixel?
58 of the 5,294 measured, 1.1% of the corpus, ranking 77th of the 88 companies in this index.
