What this actually means

healthline.com recorded 85 fewer third-party requests in the visit configured for Brave-list blocking.

The visit with no blocking made 166 requests; the visit configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit) recorded 85 fewer third-party requests. The blocker directly stopped 12 requests; the remaining difference may include follow-on requests that never started once their sources were blocked, plus run-to-run variance.

Review-worthy

Bottom line: this visit has review-worthy signals

The scan observed signals a non-expert should not have to decode from raw request tables.

The cards below translate the evidence into plain language. Where a measured distribution exists, severity ranks this visit against percentiles from the report's exact schema, methodology, tracker-catalog, ServiceRole-taxonomy, metric-contract, producer, and Global Privacy Control cohort, with each percentile card naming its metric-specific measured-site denominator (among 98 sites with a successful load across all cohorts; other methodologies, request-capped visits, and post-choice consent visits are excluded from this denominator, while failed or block-page attempts are outside that coverage), a curated set of popular, mostly commercial sites, not a random sample of the web, and otherwise uses fixed reference thresholds. The request log, domain table, and methodology remain below for verification.

166 requests observed in one controlled visit.

Worth checking

76 requests matched Brave Shields filter lists

76 requests matched the default filter lists of Brave Shields, the ad and tracker blocker built into the Brave browser, while loading normally.

Computed with Brave's own ad-block engine and default filter lists in classification mode: matched requests were not blocked by the scanner and remain in this report's observed request counts. Matching shows what Shields would target on this visit's traffic; an actual Shields visit blocks these and also prevents their follow-on requests, so this number is neither a measured block count nor the total effect.

The hand-curated service catalog separately matched 19 request rows in this visit.Show matched requests

Nothing observed

Lower values observed across comparable metrics in the Brave-list blocking attempt

With the scanner configured to apply Brave's ad-block engine and default Shields filter lists (a simulation in this scanner's browser, not a live Brave-browser visit; application was not verified), this paired visit showed 85 fewer third-party requests, 12 fewer third-party cookies and 19 fewer tracking-related service requests.

Services only seen in the unblocked visit: Google, Amazon Ads and DoubleVerify, plus 2 others. The blocking visit's engine directly blocked 12 requests; the remaining difference may include follow-on requests that never started once their sources were blocked. A single paired comparison can also reflect run-to-run variance (ad rotation, caching, experiments), so treat this as an observed difference, not a measured blocking rate.

Worth checking

Consent tooling and requests to tracking-service entities appeared before any choice

www.healthline.com sent a request to OneTrust, a consent management platform (the tooling that shows cookie banners), and the request log included 5 distinct catalogued tracking-related services before the scanner made any consent choice; 5 companies answered.

A request to the platform's loader proves the page attempted to fetch consent tooling; an observed response supports delivery, but neither fact proves a banner was visibly shown to this scanner. Banner display can vary by region and visit context. The scanner never clicks a banner in this mode, so this report records requests made before the scanner made a consent choice. It does not determine whether any request required consent or whether the site's behavior complied with applicable law. More tracking-service entities or requests may appear after "Accept" than this report captures, so the counts here are lower bounds for users who consent.

Consent platform detected via a request to cdn.cookielaw.org.

Context

Tracking companies the privacy policy does not appear to name

DoubleVerify and The Trade Desk were sent requests during this visit, but the policy text matched none of the names this scan knows those companies by.

Policies often disclose vendor categories rather than company names, so an unnamed vendor is a transparency gap worth reviewing, not automatically a violation. Named in the policy: Google and LiveRamp.

Policy at https://www.healthline.com/about/{seg}; 0 checkable statements matched; 2 of 4 observed tracking companies named in the policy; policy mentions of Amazon Ads are unknown because the historical alias matcher was incomplete.

Review-worthy

Catalogued service domains recorded responses during this visit

Google, Amazon Ads and DoubleVerify, plus 2 others appeared in the request log.

A catalog match identifies a maintainer-reviewed service/domain mapping; it does not establish why an individual request occurred, what it carried, or whether profiling happened. Functional catalog labels include advertising, analytics / tag management and advertising measurement / verification. This scan could not identify 24 of the 37 third-party hosts recorded here, so it cannot say who operates them. That is a limit of identity coverage, not evidence about the site.

Context

Requests were dispatched to catalogued major-platform domains

This visit dispatched requests to catalogued domains for Google.

The domain matches identify services, not the requests' purpose, payload, or whether any profile linking occurred.

8 requests to these platforms.Show catalog-matched requests

Nothing observed

Google Analytics present, no remarketing signal

Google Analytics was observed, but no DoubleClick remarketing sync appeared in this visit.

Standard analytics collection was observed, without the stats.g.doubleclick.net advertising sync.

Worth checking

Third-party cookies were present

12 third-party cookies showed up during the visit.

The scanner observed cookie metadata whose domain crossed the scanned site's registrable-domain boundary. This report does not retain cookie values or partition keys, so it does not establish whether a cookie was a persistent identifier or could recognize a visitor across sites.

40 cookies total in this report.At or above the 75th-percentile mark for third-party cookies across the 88 sites measured for this metric.

Context

Interaction-monitoring signal involving a third-party script

Broad mouse, touch, click, scroll, visibility and keyboard listener coverage was registered during the visit through call chains that included a third-party script.

This is a behavioral instrumentation signal from listener registration, stack-attributed script origins, and known-vendor requests: it shows the page was instrumented to observe interaction, not that anything was transmitted. Stack attribution records the script origins present in the bounded registration call chain; a cross-site origin in that chain does not by itself establish that the cross-site script registered the listener, because first-party code can register its own listeners through a helper served from elsewhere. A different registrable domain is also not by itself a different operator: sites commonly serve their own scripts from a separate asset domain, so the card says third party only when the catalog or reviewed ownership attributes an origin to another organization. On scanners that run the active keystroke-capture probe, actual transmission is tested separately (a synthetic value is typed, never real input, and no typed values are collected); treat this card as a review prompt rather than proof.

16 interaction-listener registrations with https://cdn.cookielaw.org/, https://*.adspsp.com/ and https://*.doubleverify.com/, plus 1 other in the registration call chain

Nothing observed

No fingerprint-like API calls observed

The scan did not observe the instrumented high-entropy browser APIs.

This is an observation layer, not proof that fingerprinting is impossible.

0 API families recorded.

Recorded provenance is self-reported measurement metadata, not a cryptographic attestation. The public versioned report JSON contains the retained public evidence; see the methodology for interpretation and retention limits.

This report covers what the scanner measures, not everything a site can do. 16 browser surfaces are not instrumented at all (Every page except the one that was scanned; Anything that only loads after scrolling or interaction; Why a request happened, as a causal chain; and 13 others), 3 capabilities are declined by policy, and 3 are outside what any single visit can see. Their absence from this report is not evidence that they did not occur. Read the published coverage boundary.

Detector accuracy is unmeasured. No calibration study currently publishes a precision or recall for the detectors on this page, so a detector match here is a recorded observation, not a calibrated classification. How detector accuracy is measured.

Approved use boundary: This report is investigative evidence that requires independent corroboration. It is not a standalone legal determination and not the sole exhibit in a legal proceeding. Recorded in this project's release manifest on .
