02 · Data you can retrieve
Web analytics, traffic data and competitive-intelligence datasets
03 · Actions and write paths
The targeted review confirmed this Similarweb capability surface: Web analytics, traffic data and competitive-intelligence datasets. It did not normalize every mutation tool. Treat writes as unapproved until each current tool, scope, plan and approval behavior is verified.
04 · Authentication and permissions
For Similarweb, the audited authentication model is: Authentication model is documented by the vendor; inspect the cited source before implementation. The effective permission model is: Existing vendor identity, account, tenant, and permission controls should be treated as the authorization boundary. Reconfirm the cited first-party source before implementation.

Single-platform patterns
- Market, competitor, and channel intelligence radar
- Executive insight brief
- Experiment review board
- Anomaly investigation room
Multi-platform compositions
- Similarweb + warehouse or semantic layer: executive insight brief
- Similarweb + CRM or lifecycle platform + work-management system: cross-system decision workspace
Evidence and dates
First-party references, with publisher and review dates separated
“Publisher updated” is shown only when the page exposes an update date. “BYO-UI reviewed” records when this research checked the reference. A missing publisher date is reported as missing—not replaced with the review date.
