Expert SEO service providers, compared on what they publish

Agencies with a verified published price

How to shortlist an expert SEO service

1. Define the search problem before you take calls. Technical remediation, content depth, local visibility, digital PR and ecommerce feed work are different jobs that different providers do well. Write down which one you believe you have, and why, in three sentences. Every candidate should either agree with your diagnosis or tell you plainly that you are wrong, with a reason.
2. Filter on the disclosed minimum and term. Ask in writing for the smallest engagement accepted, the contract length and the notice period. It takes one email, needs no meeting, and eliminates more candidates than any other question. Where a published starting price exists, treat it as the narrowest scope the provider sells rather than as a forecast of your cost.
3. Buy an audit before you buy a retainer. A paid audit at a fixed price is the cheapest way to test judgement. You get a document you own, a view of how the provider thinks, and a prioritised list you could take elsewhere. Google's hiring guidance suggests granting read access for an audit rather than write access to your site, and that is the right posture.
4. Check who does the work and what is subcontracted. Content writing, development and link acquisition are commonly outsourced. That is normal, but it changes turnaround, quality control and accountability. Ask which parts leave the building, who reviews them, and who you speak to on a Tuesday afternoon when a deployment breaks something on the site.
5. Set ownership and reporting before the first invoice. You should own the analytics property, the Search Console property and the site itself, with the provider granted access. Agree which queries are tracked, what counts as a conversion and that each report states what was actually shipped that month, not only what moved.

What the providers in our index actually publish

For each provider we record what appears on their own site: any published pricing or starting retainer, a stated minimum engagement, named clients, service focus, location and team size, together with the date the page was read. Nothing here is submitted by the agencies and nothing is ranked by payment, which means a provider that publishes nothing simply shows fewer fields rather than a lower position.

Publication is itself a signal. A firm willing to state a floor in public is describing a business with a defined scope, and it saves you the discovery call whose only purpose is to establish whether you can afford them. The corollary matters too: a published price is a floor for the smallest version of the service, and the quote for your situation will usually be higher.

What genuinely moves the price of search work

Site scale and technical condition come first. A large catalogue with template problems, or a site rebuilt three times with old URLs left dangling, needs engineering time before any content work pays back. Competitive intensity comes second, since the amount of work required to rank is defined by what the incumbents already publish rather than by your budget.

Then the mix. Original content, digital PR, development capacity and specialist work such as international or ecommerce feeds each carry their own cost, and bundling them into one monthly number is what makes proposals impossible to compare. Ask for a breakdown by workstream with the hours behind each, and compare those rather than the headline figure.

The claims that should end a conversation

Guaranteed rankings are the clearest disqualifier, because no provider controls the ranking system and any guarantee is either meaningless or attached to terms nobody searches for. Google's guidance on hiring an SEO warns buyers away from guaranteed results, and a provider offering one is either uninformed or counting on you not checking.

Volume link packages are the second. Google's spam policies describe link schemes intended to manipulate rankings as a violation of those policies, and the risk of that work sits with your domain rather than with the vendor who sold it. Ask each candidate how they earn links, and treat any answer involving a monthly quota of placements as a red flag rather than a deliverable.

Questions people actually ask

Is a higher price a proxy for better work?

Only loosely. Price tracks seniority, capacity and demand, so a cheap retainer usually means fewer hours or more automation, but an expensive one can also mean an agency with a large overhead. Compare the hours funded and the seniority of the people delivering them, and the price differences usually explain themselves.

Freelancer, boutique or full service agency?

A senior freelancer can outperform an agency on a focused problem and is often better value. A boutique brings a small team with a specialism. A full service agency brings capacity and coordination across channels, which matters when search sits alongside paid media and content production. Match the shape to the problem rather than to your revenue.

How do I evaluate a case study?

Ask what else changed in the same period, since a site migration, a pricing change or a large brand campaign will move search numbers on their own. Then ask for the client's contact details. A case study you cannot verify is a claim, and the willingness to connect you with the client is the real signal.

What should the first ninety days include?

A technical baseline, a prioritised fix list with owners, a query set agreed with you and the first content or remediation shipped. Ask each candidate for that plan in writing before signing, and hold the first quarterly review to their own forecast rather than to a general expectation of progress.
