hsadspixel.net

hsadspixel.net is the host HubSpot uses for its advertising pixel — the piece that connects a visit on a customer's website back to the ad campaigns that customer runs. It appears on marketing sites whose owners buy ads and want to attribute what those ads produced. This index recorded it on 102 of the 5,294 sites measured, 1.9%, and the more useful number is a different one: on 100 of those 102 pages, hs-banner.com was present too.

One vendor, six hosts, one line in most reports

This host is almost never the only HubSpot endpoint on a page. hs-banner.com was present on 100 of the 102 sites, 98%. hs-analytics.net on 98, 96.1%. HubSpot's catalogued domains on 88, 86.3%. hsforms.com on 82, 80.4%. hubapi.com on 67, 65.7%. hscollectedforms.net on 39, 38.2%.

That matters for anyone reading a privacy report or a cookie table, because those documents usually collapse the lot into a single vendor row. The page is contacting six or seven separate hosts; the report says one word. If you are auditing rather than summarising, the host list is the thing to reconcile against, and the count of distinct destinations will be higher than the count of named vendors.

Google was on 97 of the sites, 95.1%, and LinkedIn on 39, 38.2% — a combination that points squarely at business-to-business advertising.

These are busy pages

The median site here contacted 14 companies over 50 requests, with 3 of them classified as tracking. Among the 88 companies in this index that is 18th by median company count, so the pages carrying this pixel sit well inside the heavy end of the field without being extreme.

The examples explain why. Much of the list is advertising technology marketing its own products — applovin.com at rank 165 with 18 companies, inmobi.com at 287 with 16, bidmachine.io at 1044 with 22, seedtag.com at 920 with 13 — plus infrastructure and security vendors: rackspace.com at 1270 with 14, datadome.co at 1309 with 19, mediatek.com at 508 with 14. hubspot.com itself is in the sample at rank 251, contacting 11 companies.

Eleven companies before the banner at the median

On 97 of the 102 sites, 95.1%, at least one company was contacted before the consent banner could have been answered. The median site had 11 companies inside that window — 18th-highest of the 88 companies indexed here — and added 2 more after it closed.

At the extremes, datadome.co had 18 of its 19 companies inside the window and seedtag.com all 13 of its 13, while mediatek.com and abovedomains.com recorded none at all. hsadspixel.net was present on pages of both kinds.

Timing, and one page nearly ten seconds out

The median first third-party contact for the group came at 659 ms, and the earliest anywhere in it at 115 ms. Ranked against the other 87 companies from latest median to earliest, this group sits 46th — the middle of the index.

The individual figures are far less tidy. datadome.co made first contact at 297 ms, netlify.app at 327 ms, seedtag.com at 430 ms. abovedomains.com at rank 997 did not reach any third party until 9,610 ms — nearly ten seconds — and contacted 11 companies once it did, none of them inside the consent window. mediatek.com sat at 2,045 ms with the same pattern. A single median hides page behaviour that differs by two orders of magnitude.

Consent tooling was present on fewer than half

A consent tool was detected on 40 of the 102 sites. Seen alongside were OneTrust on 20, Osano on 5, CookieYes on 5, Cookiebot on 4, Usercentrics on 3 and Iubenda on 1 — counts that overlap rather than partition, since a site can carry more than one banner.

Among the examples, applovin.com, netlify.app and datadome.co were recorded with OneTrust and spaggiari.eu with Cookiebot, while hubspot.com, inmobi.com, ipify.org, seedtag.com, bidmachine.io, rackspace.com and mediatek.com had none detected.

If you want the host-level view for a page you have open rather than for a group of 102, MurmStack lists the destinations individually instead of folding them into one vendor name.

The six most common are listed. The remaining 2 of 40 sites with a banner carry something outside that six. One tool is recorded per site, so these counts never overlap.

Questions

What is hsadspixel.net for?

It is HubSpot's advertising pixel endpoint: it ties activity on a customer's site back to the ad campaigns that customer is running, so spend can be attributed to outcomes.

Why do so many HubSpot hosts appear at once?

Because the product is split across endpoints by function — banner, analytics, forms, API, ads. On these 102 sites, hs-banner.com appeared on 100 and hs-analytics.net on 98, so a page that has one usually has several.

What kind of sites carry it?

Mostly companies selling to other companies. The examples are dominated by advertising technology and infrastructure vendors marketing their own products, and LinkedIn was present on 38.2% of the group.

Are these pages heavier than average?

Yes, by the measures here. The median site contacted 14 companies over 50 requests, which is 18th of the 88 companies in this index by median company count.

What happened on abovedomains.com?

Nothing was contacted for 9,610 ms, then 11 companies were, none of them inside the consent window. It is the latest first contact among these examples by a wide margin, against a group median of 659 ms.
