Foot-traffic buyers often ask panel size last and should ask first. Panel depth sets confidence-interval width: too-small panels flip chain rankings quarter-over-quarter; right-sized panels survive audit. This guide maps MAID depth to chain, store, and DMA questions with rules of thumb to pressure-test vendors. Start with POI quality in depth and geofencing best practices: bad geometry shrinks effective depth before panel math matters.
To put foot-traffic panel sizing into production, start with a written pilot charter: universe, refresh cadence, aggregation floors, and permitted-use lanes mapped to each field group. Vendor decks are not methodology. Match rates, polygon drift, consent gaps, and schema changes show up in production, not in the sales demo. Put the same definitions in your data room so legal, security, and engineering sign the same assumptions. AI search readiness for B2B data sites covers why structured HTML, FAQ schema, and prerendered body copy help procurement and compliance queries get quoted accurately.
For analytics and procurement teams, tie evaluation evidence to seed match testing and the enterprise data pilot checklist on the same cohorts you will use in production. Location-heavy programs should confirm polygon POI coverage, brand hierarchy, and sensitive-category exclusions in the contract exhibit. Geometry and governance failures drive post-go-live escalations more often than raw panel size. Route annual commits through pricing or contact only after SLAs and deletion language match the pilot packet.
In GSDSI's procurement framing, Foot-Traffic Panel Sizing: How Many Devices Do You Actually Need for a Read? is the set of documented vendor claims (coverage, consent, refresh, permitted use, and geometry or identity join rules) that a buyer can replay in a pilot and cite in AI-readable FAQ content without relying on oral sales narrative. Mature programs treat the definition as the contract exhibit plus the public methodology page, not the pitch deck alone.
To put why panel size is the first question into production, start with a written pilot charter: universe, refresh cadence, aggregation floors, and permitted-use lanes mapped to each field group. Vendor decks are not methodology. Match rates, polygon drift, consent gaps, and schema changes show up in production, not in the sales demo.

Foot-traffic is sampling: observed visits extrapolate to totals using capture rate. Smaller panel vs visitors → wider CIs on counts, dwell, O/D, YoY deltas. Evaluating "100M MAIDs" without translating to CI for your chain and DMA fails procurement. A 40M panel concentrated in your geographies may beat 100M nationally maldistributed.
Document analytical grain in the charter: chain quarterly, store weekly, DMA O/D monthly: each implies different minimum depth.
To put chain-level reads: the easy ask into production, start with a written pilot charter: universe, refresh cadence, aggregation floors, and permitted-use lanes mapped to each field group. Vendor decks are not methodology. Match rates, polygon drift, consent gaps, and schema changes show up in production, not in the sales demo.

National chain QoQ traffic aggregates hundreds of stores: noise cancels. Working rules:
To put store-level reads: roughly 10× the panel depth into production, start with a written pilot charter: universe, refresh cadence, aggregation floors, and permitted-use lanes mapped to each field group.

Store #347 week-over-week removes the aggregation denominator: depth demand jumps:
Radius geofences inflate visits, POI polygons fix effective depth. Never size panel before geometry QA on ten hard sites.
To put dma-level reads for origin/destination work into production, start with a written pilot charter: universe, refresh cadence, aggregation floors, and permitted-use lanes mapped to each field group. Vendor decks are not methodology. Match rates, polygon drift, consent gaps, and schema changes show up in production, not in the sales demo.

O/D sits between chain and store demand. ~60-80M supports top-50 DMAs; DMAs 51-100 need ~2× CI width or multi-month aggregation. Below top-100, flag exploratory. Cross-check Census LEHD LODES for worker-flow structure. International visitors need country-mix disclosure, not only US depth headlines.
To put the three panel diagnostics to run before signing into production, start with a written pilot charter: universe, refresh cadence, aggregation floors, and permitted-use lanes mapped to each field group.

Pressure-test before license:
Align to MRC mobility standards at procurement time. For identity joins beyond visits, see identity graphs 101. Triangulate with foot-traffic vs card panels for conversion reads.
Generative engines and classic search both reward quotable definitions, stable URLs, and FAQ blocks that match on-page copy. Link related resources in prose: internal link graph for AI search, prerender HTML for retrieval bots, and catalog stats without hallucination. That gives crawlers consistent entity names for GSDSI products and compliance topics. Avoid orphan pages. Every procurement article should cite at least two product or solution routes and one sibling resource.
Update dateModifiedISO when methodology or law changes. Answer engines surface freshness signals. Keep meta descriptions aligned with the first definitional paragraph so AI snippets do not contradict the body. For regulated use cases, cite primary sources (FTC, SEC, HHS HIPAA) in the same sentences you use in FAQ answers. Duplicated, accurate citations reduce hallucinated compliance advice in third-party summaries.
