Google Reviews | Low-Star Business Finder

What you can export

Use this Google low-star review business finder to identify businesses with recent negative-review activity. Supply a business search, location, time window and star ceiling to export published business contacts, matching review counts and review-window coverage.

Each result is a business summary. Reviewer names, profiles, avatars and review text are excluded. Counts are lower bounds when scanComplete is false.

Use the input form's example values for a first run. Prefills are examples, not API defaults; check the billing and limits before starting.

{
  "searches": [
    {
      "query": "dentist",
      "location": "Austin, TX"
    }
  ],
  "maxBusinessesPerSearch": 3,
  "windowDays": 180,
  "maxStars": 2
}

Input

Field	Type	What it does
searches	array	Objects with query (category or keywords) and location text; form prefill is dentist in Austin, TX.
maxBusinessesPerSearch	integer	Maximum businesses scanned per search before filtering; form prefill 3. Zero, omitted or null means no work.
windowDays	integer	Positive window in days before run start; form prefill 180. Omitted or null means no work.
maxStars	integer	Count stars from 1 through this value, between 1 and 5; form prefill 2 selects 1–2 stars. Omitted or null means no work.
minimumLowStarCount	integer	Minimum observed count for output, nonnegative; omitted or null uses 1. Zero includes businesses with no observed low-star reviews.

Omitting searches (including {}) or sending [] is refused before any run or charge. With other inputs valid, null searches succeeds with guidance and no rows; Actor Start still applies. Input rejected by the Actor produces guidance and an ERRORS record, with no source request or result row.

Output

One business row per search context; duplicates within a search are removed by place ID. The same business can appear under separate searches.

  "overallRating": 4.2,
  "totalReviewCount": 123,
  "lowStarCountInWindow": 2,
  "newestLowStarReviewAt": "2026-10-04T10:13:20Z",

newestLowStarReviewAt	Newest matching review timestamp in UTC ISO 8601, or null when none observed.
oldestReviewReadAt	Oldest review timestamp read, including reviews outside the window, in UTC ISO 8601; null if no dated review was read.

scrapedAt	UTC ISO 8601 timestamp when the row was assembled.

Coverage and billing

Uses anonymous Google Search-side HTTP results and newest-first review paging. No signed-in Maps reviews route is used. Searches use English interface labels and the US search-region setting. Location text guides Google's ranking; results are not an exhaustive or strict geographic census. The maximum limits businesses scanned, so the minimum-count filter can yield fewer rows.

Edited reviews are counted at the timestamp Google exposes, which may be their edit date. Source changes, challenges, invalid ordering, broken continuation, a terminal count below the published total while still inside the window, and the 100-page review limit per business can interrupt scans. Incomplete rows retain observed counts and scanComplete: false; review failures and skipped business summaries are recorded in ERRORS, never in the dataset. Review bodies are discarded after projection and never logged or stored.

Pay per event: one dataset item per delivered business row, plus an Actor Start event when configured. The Actor stops fetching and delivering when the customer's charge limit binds. No-match runs succeed with guidance; runs where every attempted search fails and no row is delivered fail with a safe message. Pricing is shown on the Actor's pricing page.
