Trusting local SEO reviews or checking supplier paperwork

What to take away

• A plumbing firm in Leeds that picks a local SEO supplier purely on a 4.8-star average is gambling. Ratings show satisfaction; they do not show whether the supplier can evidence a lawful, repeatable process.
• Treat reviews as one input. Weigh them against company registration, staff named on the contract, and a written method for how rankings and calls will be tracked.
• Build a shortlist of three to five suppliers, score each on the same criteria, and keep the evidence in one file.
• Check enforcement and accreditation records where money or personal data changes hands. The ICO publishes the action it has taken against organisations, which is a useful signal of how a supplier handles risk.
• Ask what happens to review content and tracking cookies on your own site, because consent obligations sit with you, not only the agency.

Why local SEO reviews are a starting point, not a verdict

A rating is a summary of other people's experiences. It tells you that a supplier can keep some clients happy. It does not tell you whether those clients sold the same services, in the same towns, at the same budget.

For a dental practice in Bristol, a supplier that excels at multi-location healthcare marketing may be a poor fit for a single-site clinic. The reviews will not flag that mismatch. You have to.

Treat every review as a claim to be tested. If a review says the agency doubled calls in three months, ask what baseline was used and how calls were attributed. If the answer is vague, the review is marketing copy.

Reviews also vary by platform. Google reviews on a supplier's own business profile reward customers who were asked at the right moment. Consumer review sites skew towards complaints. Neither is neutral.

This is also why a review-only approach fails procurement. Finance teams want a paper trail. Reviews are not a paper trail.

What a credible review method looks like

A repeatable method beats a gut feeling. Set your criteria before you read a single review, so you are not swayed by the loudest testimonial.

Start with fit: sector, geography, and the size of the accounts the supplier normally handles. Then process: how they research keywords, build location pages, and report results. Then risk: data handling, contract terms, and exit arrangements.

Score each supplier out of five on every criterion. Keep the same weighting across the shortlist. If a supplier scores well on reputation but poorly on process, the totals will show it.

Write down what evidence would change your mind. If you cannot describe the document that would move a supplier up or down, your criteria are too vague to defend.

Set a minimum score for risk. A supplier that cannot answer questions about data protection should not proceed, however good the reviews look.

Reading reviews without being misled

Reviews on a supplier's own site are curated. Reviews on independent platforms are harder to control, but they still skew towards people with strong opinions.

Look for patterns rather than individual scores. Do several reviews mention slow reporting, or staff turnover? Do they name the same account manager? Patterns are more informative than averages.

Check dates. A cluster of five-star reviews in one month, followed by silence, can indicate a campaign rather than steady delivery. A steady trickle over two years is a better sign.

Be wary of reviews that describe results without context. A claim to be ranked number one means little without the keyword, the location, and the date.

If you want to know which third-party datasets are worth pulling to test those claims, our guide to local SEO agency reviews: data and sources explains the difference between platform exports and agency-supplied summaries.

Comparing suppliers on the same evidence

Comparison only works if you compare like with like. Build a table with one row per supplier and one column per criterion. Fill it from documents, not from sales calls.

Ask each supplier for a sample monthly report with client details removed. Ask for the name of the person who will run your account and how many accounts they hold. Ask how they measure calls and form submissions.

Where a supplier cannot provide evidence, record that as a gap. Gaps are data too. A supplier with two gaps may still win, but you should know why.

For a structured way to run this comparison, our guide to local SEO product comparison: data and sources sets out which sources to trust and how to record them.

Verifying the company behind the reviews

Before you sign, confirm the supplier exists as a registered entity. The Companies House register lets you check incorporation date, filing history, and whether the directors have a track record of dissolved companies.

Look at the filing history, not just the status. Late accounts or a change of name can be innocent, but they deserve a question. A dormant company with a glossy website deserves two.

Also check the SIC codes on the register. They describe the trading activity the company reported. A code unrelated to marketing is not fatal, but it is worth asking about.

If the supplier trades under a different name from the registered company, ask why and get the relationship in writing. This matters if you later need to enforce a contract.

Check whether the person who pitched to you is employed by the company or is a freelancer reselling services. Both can work, but the contract should reflect reality.

Accreditation and enforcement checks

Membership of a recognised trade body is not a guarantee, but it does mean the supplier agreed to a code of conduct. The criteria for choosing an IPA member agency explain what accredited agencies commit to, which is useful language to borrow in your own procurement questions.

Enforcement records are the other side of the coin. The ICO enforcement action list shows organisations that have been penalised, including for nuisance marketing and data breaches. A supplier on that list needs a very good explanation.

You can also check whether a marketing claim crossed a regulatory line. The Trading Standards referrals process explains how the advertising regulator passes non-compliant cases to Trading Standards, which is relevant if a supplier's own advertising looks too good to be true.

None of these checks take long. Together they take less time than recovering from a bad contract.

Questions to ask about data and tracking

Local SEO work often involves adding tracking scripts, call-tracking numbers, and cookies to your site. That puts obligations on you as the site owner.

The ICO guidance on storage and access technologies sets out when consent is needed for cookies and similar tools. Ask the supplier how their tracking complies, and who updates the consent banner.

Ask where data is stored and who can access it. Ask what happens to tracking scripts and accounts when the contract ends. A supplier that holds your analytics account hostage is a problem.

Get these answers in writing before the first invoice. Verbal assurances are difficult to rely on later.

Scoring model you can reuse

A simple weighted model keeps decisions defensible. Allocate 100 points across five areas, then adjust to your priorities.

Sector and location fit 20

Method and reporting 25

Team and continuity 15

Risk and compliance 25

Commercial terms 15

Score each supplier out of the weight available. Keep the evidence next to the score. If you are challenged later, you can show why the winner won.

Providers are not the only variable. Before you weight anything, it helps to know which datasets are worth pulling, and our guide to local SEO best providers: data and sources covers what each source does and does not prove.

A worked example: for a team paying £400 a month, a supplier scoring 78 might beat one scoring 82 if the higher scorer needs a 24-month lock-in. Cost of exit is part of value.

Red flags in local SEO reviews and pitches

Guaranteed rankings are the classic warning sign. No supplier controls the search engine's algorithm, so a guarantee is either meaningless or a promise to use tactics you would not want.

Other flags include refusal to name the account team, reports that show rankings but not leads, and contracts that assign no ownership of content or accounts to you.

Be cautious about suppliers who only show reviews from one platform. A spread of sources is harder to fake.

Watch for reports that compare your performance to unnamed competitors. Without the competitor named and dated, the comparison proves nothing.

Finally, watch for pressure to sign quickly. Urgency is a sales tactic, not a reason.

How to run a shortlist in practice

Start with eight to ten names from search, trade bodies, and peer recommendations. Screen down to three to five using public records and review patterns.

Send the same brief to each remaining supplier. Ask for a written response, not a slide deck. Compare answers side by side.

Hold one call per supplier, with the same questions. Take notes in the same format. This reduces the halo effect of a good presenter.

Check references by phone where possible. Ask the referee what went wrong, not just what went right. You will learn more.

Our local SEO selection checklist in England turns these steps into a tick-list you can hand to a colleague.

Where reviews fit in the final decision

Reviews should carry real weight, just not all of it. Use them to shortlist and to sense-check culture. Use documents to decide.

If a supplier has strong reviews and strong evidence, the decision is easy. If the two conflict, trust the evidence and ask why the reviews differ.

Record your reasoning. A short memo explaining the choice protects you if a stakeholder questions it later.

Set a review point at six months. Decide now what evidence would justify switching, and what counts as normal settling-in friction.

Keep the shortlist file after signing. It becomes the benchmark for judging the supplier's own quarterly reports.

A supplier that communicates well in month one and goes quiet in month four is a different problem from a supplier that misses the first target. Both need a conversation, not a cancellation.

Common questions

How much should I rely on star ratings when choosing a local SEO supplier?

Use them to shortlist, not to decide. Ratings show client satisfaction but not fit, method, or compliance. Pair them with registration checks and a written measurement plan.

Can I trust reviews published on a supplier's own website?

They are curated, so treat them as claims. Look for independent sources and patterns over time, and ask for referees you can speak to directly.

What public records should I check before signing?

Check the Companies House register for filings and directors, and the ICO enforcement list for regulatory action. Both are free and take minutes.

Do I need consent for the tracking an agency installs on my site?

Often yes. The ICO guidance on storage and access technologies explains when consent is required, and the obligation usually sits with you as the site owner. Ask the supplier to document how their tools comply.
