Before you trust local SEO agency reviews, check the evidence

What to take away

What does a local SEO agency review actually assess?

A review assesses stated scope, pricing structure, reporting cadence, contract terms and the evidence behind performance claims. It does not assess how pleasant a supplier is to work with, and it cannot verify results a buyer has not shared. That distinction matters, because review pages sometimes present vendor-supplied case studies as independent findings.

The honest position is narrower. A desk review can compare published terms and public data. It cannot confirm that a named client saw a particular uplift, and no reviewer should imply otherwise without that client's documentation.

How should vendor claims be separated from independent evidence?

Label every statement. Vendor claims are what the supplier publishes about itself. Independent evidence comes from a named source with a date: Companies House filings for company size and accounts, the Office for National Statistics for market data, Google Business Profile documentation for platform features and rules, and the Advertising Standards Authority's published rulings database for how comparable claims have been judged. Editorial judgement is the reviewer's reasoning applied to both, and it should be visible rather than hidden behind a score.

Misleading marketing claims sit inside a legal framework, not just an ethical one. The Consumer Protection from Unfair Trading Regulations 2008 made misleading commercial practices unlawful, and the Digital Markets, Competition and Consumers Act 2024 gives the Competition and Markets Authority direct enforcement powers over them. Advertising claims follow a separate route, run by the Advertising Standards Authority under the CAP Code, and its rulings database shows how performance claims in this sector have been decided before.

Which numbers need a named source?

Any figure that influences a buying decision needs a source and a date. That includes typical retainer bands, average project timelines and claimed ranking improvements. Where no source exists, write a labelled illustrative example instead, for example a team paying £400 a month for local listings management across six locations.

Green claims often arrive with a figure attached — a percentage of emissions offset, a carbon-neutral hosting promise. The Climate Change Act 2008 sets the statutory framework for UK climate targets, while the CMA's Green Claims Code and the CAP Code's rules on environmental claims set out what a supplier must be able to evidence. If the agency cannot produce the document behind the figure, treat it as an unverified claim and score it as one.

How do you score suppliers consistently?

Fix the criteria, the weightings and the review date before you look at any supplier. Then apply them without adjustment. If one agency is scored on reporting quality and another is not, the comparison is meaningless.

Score only what the supplier can evidence and what you can check. A published price, a named contract term and a documented reporting sample carry weight; an unlabelled ranking chart does not. Where a criterion depends on data you cannot see, record it as unverified rather than awarding a middle score to be fair.

Which review platforms should buyers actually check?

In the UK, buyers read Google reviews on the supplier's Business Profile, Trustpilot, Clutch and G2. Each publishes rules on fake, incentivised and gated reviews, and each gives you a way to flag a review you think breaks them. Google's Business Profile policies ban fake and incentivised reviews outright.

Gamed reviews show a pattern rather than a single tell: a burst of reviews over a few days, near-identical wording, reviewers with no other activity, and praise that names no location or service. Check the dates against the supplier's own campaign calendar, and read whether replies carry specifics or a template.

Score platform data as vendor-adjacent rather than independent. A star average remains a vendor claim until you can read the reviews behind it.

Worked example: scoring three suppliers

A fictional England buyer compares three agencies on the same five criteria, each weighted equally out of 10.

Agency B leads on evidence and reporting. Agency C leads on price transparency and exit terms. The buyer requests documentation for the two lowest claims and holds the shortlist until those arrive. If Agency B cannot evidence its reporting sample, the score changes.

Where do you report a misleading claim?

The Advertising Standards Authority takes complaints about specific ads and claims through the online complaint form on its website, and its rulings database shows whether a supplier has been pulled up before. The Competition and Markets Authority takes reports of misleading commercial practices under the Digital Markets, Competition and Consumers Act 2024, through the reporting route published on gov.uk.

Keep the evidence with the report: a screenshot, the page URL, the date and the exact wording. That is the same standard this method asks of a supplier.

Common questions

Can a desk review verify agency results?

No. It can verify what a supplier publishes and compare it with independent sources. Confirming a specific client outcome requires that client's own data, supplied with permission.

Why does the review date matter so much?

Pricing, contract terms and platform features change. A review without a stated date gives the reader no way to judge whether the findings still apply, so the date belongs next to the score.

What should a buyer do when evidence is missing?

Ask for the source directly, in writing, and set a deadline. If the supplier cannot name where a figure came from, treat the claim as unverified and score it accordingly.

Where should comparison data come from?

Start with primary documentation and named public sources: Companies House filings, Office for National Statistics datasets, Google Business Profile documentation and the ASA rulings database. Local SEO best providers: data and sources sets out which sources carry weight when you build that shortlist.
