    • and more!

Brand Openings and Closings

  • We rely on POI metadata to track store openings and closings, and we are especially interested in understanding open/close dates for branded POIs. It can take more than a month to infer open/close dates, so we report brand open/close metrics on a one month delay.

Bug Fixes and Known Issues - Core Places and Brands

  • We discovered a few brand count fluctuations as a result of updated sourcing and metadata bugs. These corrections resulted in significant changes in the total number of POIs for each affected brand, but the new count is correct. For transparency, we'd like to list some of these corrections as examples in no particular order:
    • Pacific Sales (SG_BRAND_c9deba94693f0dc718bbb1912d6f135d). Net POI count change: US: -213 CA: 0. Bug: Previously included all Best Buys, not just those w/Pacific Sales showrooms
    • Boards Inn & Suites (SG_BRAND_29ef451d7a4dfb7d). Net POI count change: US: -130 CA: 0. Bug: Previously included other Cobblestone properties (which we have as its own brand)
    • See's Candies (SG_BRAND_861672770a2e5494d97bb9058c420a0c). Net POI count change: US: -111 CA: 0. Bug: Previously included seasonal & pop-up (but wasn't distinguished as such)
    • GoLo (SG_BRAND_caf1c8f9222e9c6d). Net POI count change: US: -81 CA: 0. Bug: Previously included "AllStar" (not just GoLo Gas)

Enhancements - Categories

Below are some noteworthy category count changes:

  • Corporate, Subsidiary, and Regional Managing Offices (551114). Net POI change: US: +7,316 CA: +459
  • Limited-Service Restaurants (722513). Net POI change: US: +1,272 CA: +203
  • Shoe Stores (448210). Net POI change: US: +890 CA: -11
  • All Other Health and Personal Care Stores (446199). Net POI change: US: +575 CA: +26
  • Fuel Dealers (454310). Net POI change: US: +523 CA: +0

Drops ⬇️

We are ingesting many sources and due to source changes and processing changes, Placekeys do drop over time. In this release, we dropped 79,595 Placekeys (26,558 branded and 53,037 non-branded).
Major reasons for drops:

  • ~29K dropped as result of improved deduplication 👯
  • ~22K dropped due to address encoding changes
  • ~12K dropped due to changes to the POI encoding

To keep track of the status, predecessors, and latest successor of each Placekey, try using the new Lineage API.

Enhancements - Geometry

  • While OWNED polygons are preferred, it does not mean that SHARED polygons are inherently bad. It only means that the exact shape of each POI within the polygon is not discernible, but the general location can be identified by the centroid (latitude & longitude). 🎯

  • When enclosed = FALSE, it indicates that there are reasonable means to derive a unique polygon for the POI (even when parent_placekey is not null), and we strive for 100% of branded, non-enclosed POIs to have polygon_class = "OWNED_POLYGON."

  • Last month, the percent OWNED polygons for branded, non-enclosed POIs was 77.9%

  • This month, the percent OWNED polygons for branded, non-enclosed POIs is 76.6%

Bug Fixes and Known Issues - Geometry

Enhancements - Patterns

  • In last month's delivery, SG Patterns had 4,402,283 points-of-interest (US only). This month, SG Patterns has 4,456,989 points-of-interest (US only) (net +54,706).

  • Last month, SG Patterns had 747,684,480 visits from 31,115,312 visitors. This month, SG Patterns has 966,668,416 visits from 31,035,272 visitors (delta 218,983,904 visits, -80,039 visitors).

  • In our Neighborhood Patterns product, where you can see more generalized foot traffic flows, we have:

    • 2,086,730,752 raw stops (+419,561,329 from last month)
    • 398,413,728 raw devices (+62,013,873 from last month)
  • We unintentionally fixed a known bug in which customers receiving both weekly and monthly Patterns were receiving monthly specific columns in weekly patterns deliveries.
