GIG Retail and RMI on paper: what their service descriptions say and what they cannot prove

Retail media agency reviews need engagement evidence before they can judge delivery or results. This article inspects public service descriptions from GIG Retail and RMI for retailer-controlled advertising operations. It does not review an agency engagement and withholds performance, usability and outcome verdicts.

Exact subjects and reviewing status

Commissioning publication: shopperads.co.uk. Inspection date: 6 September 2026. The documentary subjects are GIG Retail's Our approach page and RMI's How we help retailers page, linked below. Neither page supplied an established publication version for this research.

An independent reviewing body and named human reviewers have not been appointed. The work was AI-assisted desk inspection: open each direct page, identify the stated retailer-service scope and separate it from claims needing engagement evidence. No account, agency contact, proposal or campaign record was obtained.

Publisher sponsorships, affiliate links and other commercial relationships remain unverified. No paid sample or agency service was used in this research. Confirm the publication's full conflicts position before publication; this limited method does not prove independence.

GIG Retail's documentary offering

GIG Retail's Our approach describes support ranging from selected operational work to retail-media network management. This is a first-party service description relevant to a retailer considering the boundary between internal work and external support.

Ask which activities would belong to the actual proposed engagement. A broad network-management description does not establish the contract, assigned team or technology responsibilities. Claims about growth, investment returns or exceeding expectations are not accepted here as observed evidence.

No GIG delivery, support interaction or customer feedback was independently examined. The page can inform an evidence request; it cannot support a satisfaction score or recommendation to appoint the agency.

RMI's documentary offering

RMI's retailer-services page describes retail-media sales on behalf of retailers, alongside planning, execution and reporting. Its wider service description includes both online and offline activity. Restrict a digital comparison to the retailer-controlled inventory actually specified in the brief.

The page's promotional results and selected testimonials do not establish outcomes for an England retailer's proposed assignment. No claim about revenue, efficiency, customer satisfaction or campaign effectiveness is adopted by this review.

No RMI service contract, reporting dataset or implementation was inspected. Identify the proposed activity, responsible parties and evidence requirements before comparing this offering with another agency's scope.

External criteria are not independent engagement evidence

The NCSC's supply-chain security guidance concerns dependencies and third-party access to information. It provides a UK guidance source for asking about technology partners and data access; it is not an independent audit of either agency.

Request appropriate assurance for the actual service and identify who assesses it. Do not infer security, privacy compliance or operational reliability from a service page. No such assessment has been performed for this article.

Keep reporting claims equally bounded. Ad requests, returned content, rendered placements and visibility differ from attention. An attributed sale is not proof of a causal effect, and a modelled estimate requires its assumptions to be disclosed.

What a substantive review would need

Specify the retailer, assignment, engagement version and review period. Appoint competent reviewers and obtain authorised evidence showing what the agency actually delivered. Disclose supplier involvement in selecting records and any untested work.

A comparable assessment would hold inventory scope, deliverables and reporting definitions constant. It should document exclusions rather than treating a media-sales engagement as equivalent to a complete operating service. This is a proposed method, not a completed test plan or observed engagement.

Bounded finding

Both pages describe services relevant to further retailer-side investigation, but no independent engagement evidence supports an outcome verdict. No ranking, score or appointment recommendation is made. Keep the article held until genuine reviewers confirm sources and conflicts; any later verdict must identify the precise engagement and evidence it covers.
