Similarweb vs Adbeat vs Sell to State (Evidence Depth for Agency Account Planning)
These three answer different questions: Similarweb sizes a market, Adbeat reconstructs a competitor's paid media, and Sell to State reconstructs public-sector wins. The pricing edge for an agency comes from pairing one of them with a proprietary interpretation layer, because the underlying data is available to every competing shop bidding the same account. Pick the source that matches the retainer you already hold, then invest the margin in the analysis rather than a second subscription.

Which should an agency choose?
Similarweb vs Adbeat vs Sell to State (Evidence Depth for Agency Account Planning)
Similarweb
Best for: Agencies doing category sizing and pitch-stage market framing where breadth of coverage beats per-query precision.- Traffic and audience estimates across millions of sites and apps, useful for sizing a client's category before a pitch
- Native connectors to Salesforce and HubSpot let account teams push competitive context into existing CRM records
- Covers SEO, PPC, and consumer behavior in one dataset, so a single subscription can serve several retainer workstreams
- Estimates are modeled, not measured, and small or B2B sites often carry wide error bands that collapse under client scrutiny
- Annual contracts at enterprise tiers are hard to justify for agencies below roughly 10 active accounts
- Interpretation still falls to the analyst; the platform ships numbers, not a point of view
Adbeat
Best for: Media and performance shops that need creative and placement evidence to justify a paid strategy recommendation.- Tracks display, native, and video ad activity across 145+ networks and DSPs, with spend estimates and publisher placements
- Surfaces competitor ad copy and landing pages, which shortens creative teardown work in a pitch sprint
- Country-level coverage across 35 markets supports multi-region client accounts
- Narrow to paid media; says nothing about organic position, pricing moves, or hiring signals
- Spend figures are modeled ranges, so quoting them to a client as fact invites a credibility problem
- No white-label layer, meaning any client-facing artifact has to be rebuilt in agency branding
Sell to State
Best for: Agencies serving govtech, IT vendors, or systems integrators where tender history is the competitive battleground.- Indexes 1.4 million-plus government contract awards across 194 countries, a dataset most commercial trackers ignore
- Programmatic access via REST API, CLI, and MCP server means competitive signals can feed internal dashboards without manual export
- Supplier and buying-agency profiles support win/loss reconstruction on public-sector pursuits
- Public procurement only, so it is irrelevant to most consumer and B2B brand clients
- Raw award records require cleaning before they read as insight in a client deliverable
- Thin on creative, audience, and brand-positioning context
