How to assess digital PR agency reviews

What to take away

For a digital PR review, buyers need to know where coverage data came from, how it was measured and who checked it. A review should make those details visible.

A review that repeats an agency's own numbers restates marketing as evidence. The useful version sets its criteria first, then applies them consistently.

For a broader framework, see our guide to digital PR review and comparison methods.

What was assessed and what was not?

Assess scoring transparency by checking whether weights were published, whether every agency was assessed against the same criteria, whether exclusions are explained, and whether corrections are recorded and dated. An undated review, an uncorrected error or a coverage claim with no stated measurement window is a warning sign.

That boundary matters. A desk review can judge whether a method is transparent, not whether an agency will deliver for your brand.

Where a review cites coverage volumes, check the source, date and measurement window. A figure without a period, a review without a publication or update date, or a known error left uncorrected is a red flag, not evidence.

Check Trustpilot, Clutch, G2 and Google reviews as additional evidence of customer experience, not proof that campaign coverage or links were delivered. Read the dates and specifics, check reviewer details and any incentive or commercial disclosure, and consider agency responses. Platform ratings alone do not independently verify agency results.

How do you separate vendor claims from independent evidence?

When an agency says it secured media placements, that is a claim. A live client page carrying a link is evidence you can check; it confirms the link exists, not the claimed placement total.

For digital PR, check original publisher coverage and live links alongside independent sources, such as dated client disclosures and official records where relevant. Treat awards, rankings and self-reported reach as claims unless their basis is verifiable. Reviews on platforms such as Trustpilot, Clutch, G2 and Google can add customer context, but do not establish that a campaign achieved its claimed results.

What does a defensible scoring method look like?

Criteria should be published before scoring and applied to every agency the same way. A usable weighting can give evidence and measurement high weight; independence, disclosure and correction practices high weight; and recency and clarity medium weight. State the weights openly and explain any exclusions.

Editorial judgement belongs in the review but should sit apart from the raw evidence. Use an explicit rating scale for each criterion, such as “not evidenced”, “partly evidenced” and “well evidenced”, and explain what evidence earns each rating.

For example, a review that gives no source for its coverage total and no measurement window would be “not evidenced” on evidence and measurement, a high-weight criterion. An undated review or an uncorrected error would also rate poorly on recency or correction practice. Show how those ratings shape the conclusion rather than presenting an unexplained overall score.

Which sources should a review cite?

Prefer primary documentation: regulator pages, standards bodies, legislation and official statistics. For UK review authenticity, check Competition and Markets Authority guidance on online reviews and endorsements and the Digital Markets, Competition and Consumers Act 2024, which addresses fake reviews and practices around them. Where a review is a marketing communication, the Advertising Standards Authority and CAP Code are also relevant.

Secondary commentary is fine for context but should not carry a finding. A claim resting only on a blog post is unverified.

Plain reporting is easier to audit, and the GOV.UK content design guidance offers useful principles for presenting review findings and limitations clearly.

How should buyers use a review like this?

Use it to narrow a longlist and to write better questions. Do not treat it as a substitute for your own diligence.

Ask each agency for the source of any coverage figure, the measurement window and who verified it. Compare the answers.

Start with agencies that meet your brief. Score each one against the same criteria, keep the notes in a single file, and log the date you asked.

Where a review cannot verify something, it should say so plainly. Silence reads as endorsement.

Common questions

Can a desk review replace hands-on testing?

No. It can assess transparency and method, not delivery. Treat it as a filter before you speak to agencies, not as a final verdict.

How often should agency reviews be refreshed?

Annually at minimum, or sooner if an agency changes ownership, leadership or its stated method. Undated reviews mislead buyers.

Does a review have to disclose paid placements?

Where payment or another commercial arrangement means a review is a marketing communication, it must be clearly identifiable as marketing under the ASA’s CAP Code. Disclose any relationship that could affect the assessment in the review’s stated method, too. CMA guidance and the Digital Markets, Competition and Consumers Act 2024 address fake reviews and undisclosed incentives; paid promotion should not be presented as an independent assessment.

What should I ask an agency after reading a review?

Ask for the source and date of each headline number, the measurement method, and two client references you can contact directly. Compare answers across your shortlist before deciding.
