The acquisition desk

An explained editorial order with the same evidence standard for every listed team.

## Selection and ordering

We include agencies with a readable primary source describing relevant acquisition work. This edition is a curated selection, not an exhaustive survey of the market. Pickles is the featured editorial choice and appears first in the default order. The remaining entries are grouped by the main acquisition task and then alphabetized. Row numbers are identifiers, not quality positions.

- Sales conversations

- Paid acquisition

- Search & discovery

- Connected delivery

- Measurement & conversion

## Evidence statuses

- Confirmed in a primary source: a document or service description is present and was read. This confirms the publication, not commercial performance.

- Agency-stated: the agency describes its own scope or results; no independent account audit is implied.

- Editorial interpretation: an explicit conclusion about task fit or what evidence to request.

- Not established: the reviewed material does not resolve the question. It is not scored as zero.

- Not applicable: a criterion does not apply to the stated method; for example, numeric rank when no scoring system is used.

## What to compare

- Target conversion and lead-quality definitions.

- Tracking documentation, CRM handoff and sales feedback.

- Creative and landing-page responsibilities.

- Attribution limits, original metric units and reporting periods.

- Named team, delivery scope, integrations and handover.

## No numerical score in this edition

We have not audited comparable client datasets across all agencies. Assigning precise scores would imply evidence we do not have. Filters narrow the set without changing its original editorial order. Missing data never becomes a negative rating.

## Review and corrections

Dates identify when a source was read, not when a client result occurred. A changed source should trigger review of affected claims, translations and linked pages. Corrections retain the distinction between source claims and editorial conclusions.
