- N/A means not scored or not on file. A factor with no usable inputs is left out and the company’s other weights are scaled up (renormalized).
- Google reviews in South Dakota is the count-weighted average rating and the review count across the company’s Google listings in South Dakota. Each company’s overall Handshake Score is in the list above; it can be lower than the State Score because it also takes points off a company with fewer than 10 locations, which a State Score doesn’t.

How we ranked
The State Score runs from 0 to 10 with the same factors and weights as the Handshake Score. For each factor, when a company’s research record ties evidence to South Dakota, only the South Dakota evidence counts and the table marks the factor In-state. When it can’t, the factor uses the company’s whole record and is marked Company-wide. Licensing and the legal record can be marked In-state + company-wide: South Dakota records count together with federal and multi-state ones.
The review-volume and verification-depth adjustment from the overall score applies too, with its thresholds scaled to the size of South Dakota’s Google review market on file compared with the Pacific Northwest’s, where the thresholds were set. How many states, or how many locations, a company has doesn’t change its State Score.
To be ranked, a company needs a location on file in South Dakota and at least 100 Google reviews on its South Dakota listings.
Ties are broken by in-state Google review volume. A factor with no usable inputs is left out and the other weights are scaled up, exactly as in the overall score. The Handshake Score on each company’s page rates its whole operation in the region it is scored in and also takes points off a company with fewer than 10 locations of its own, which a State Score doesn’t.
This ranking covers the companies we’ve researched and verified in South Dakota. It isn’t every pest control company in South Dakota, and we may add more.
