this feels like a dupe of #224 (comment)

We do not expect there to be a negative impact to individual sites that are misclassified or lack a classification. A key benefit of Topics is surfacing interests that expand beyond a site’s own contextual information. A site’s own contextual information can continue to be accessible, independently of the Topics API (as it is today). While there is not a way for an individual site to request specific topics to be associated with their site, we do expect the classifier to improve over time.

The latest classifier is rolling out following the same ramp up as the updated taxonomy This updated classifier assigns numerama.com two topics: “Computers & electronics” and “News”. You can observe this directly by taking the following steps:

1. Navigate to chrome://flags and enable “Privacy Sandbox Ads APIs”
2. Enable taxonomy V2 via a command line flag --enable-features=BrowsingTopicsParameters:taxonomy_version/2 (docs)
3. Navigate to chrome://topics-internals and select the “Classifier” tab
4. Enter http://numerama.com/ in the field and select “Classify”

We do not expect there to be a negative impact to individual sites that are misclassified or lack a classification.

I disagree; sites that lack classifications may be excluded from high-value topics sharing networks as known free riders.

@leeronisrael thanks for the reply.

@patmmccann In some cases, a domain could be correctly classified with a high-value topic at the time the domain is bought, but misclassified or unclassified by the version of the classifier in use at the time the site goes live and/or is looking for a topics sharing network to join.
