How to compare enterprise SEO companies

1. Give every candidate the same technical brief. Send each firm the same short brief: your platform, your page templates, your release process and one real problem you already know about. The proposals will diverge immediately, and the divergence tells you who understood the constraint and who priced a generic retainer with your logo pasted on the cover.
2. Ask for a specification, not a strategy deck. Request a sample of the artefact your engineers will actually receive: a ticket, an acceptance criterion, a template change written so a developer can implement it without a follow-up meeting. If a firm cannot show one from previous work, the handover cost lands on your team and the roadmap absorbs it.
3. Test them on prioritisation across templates. Ask how they would rank work across your main page types, and why, given finite engineering capacity. A convincing answer talks about how many URLs each template controls and what each change is worth, rather than listing every issue an audit tool reported in severity order.
4. Check who does the work and who owns the escalation. Enterprise engagements are staffed teams, so ask for the named individuals, their allocation in days per month, and the person who will sit in a room with your CTO when a release breaks something. Insist those names appear in the statement of work rather than only in the pitch.

What actually moves an enterprise SEO fee

Four inputs explain most of the spread. Site scale and template count come first, because a programme covering a handful of templates that generate a hundred thousand URLs is a different job from one covering fifty bespoke templates with different owners. Number of markets and languages is second, and it compounds: each locale adds hreflang correctness, local content ownership and its own competitive picture. Engineering dependency is third, since a firm that must specify, queue and shepherd every change through your release process spends far more hours than one working on a platform it can edit directly.

The fourth is the scope of content production. Advisory-only engagements, where the firm specifies and your team writes, sit well below engagements where the firm also staffs writers, editors and subject reviewers. Ask for that split as a separate line so quotes that bundle differently can be compared. Migration support is normally scoped and priced as a project on top of the retainer, and it is worth buying: a replatform done without SEO input is the most reliable way to lose several years of accumulated visibility in a single weekend.

The evidence to ask for before you shortlist

Ask each firm for two or three live properties they worked on that you can inspect yourself, and then inspect them: look at how the templates handle internal linking, whether structured data is present and valid, how faceted navigation is controlled, and whether the international setup is coherent. Public work is checkable, and a firm that cannot point at any is asking you to buy on trust alone. Follow it with a reference at a company of your size and, ideally, on your platform, and ask that reference what the first ninety days were like rather than what the final numbers were.

Treat search engine documentation as the shared standard for these conversations. Google publishes its own guidance on helpful content, structured data and Core Web Vitals, and a strong candidate will reason from it directly rather than from an internal scoring system you cannot audit. Be sceptical of any firm offering guaranteed positions: nobody controls the ranking systems, and a guarantee is either about a query nobody searches or about nothing at all.

Contract terms that decide whether the gains survive

Enterprise programmes usually outlive the executive who bought them, so write the handover into the contract. Documentation, dashboards, analytics access, keyword and content inventories and any tooling configuration should be yours and exportable. Name a minimum notice period on both sides, and agree a quarterly review that reads from your own analytics and Search Console rather than from an agency-built report you cannot reproduce.

Finally, agree what happens around a migration or a major release before one is scheduled. The clause that matters is the one giving the SEO team a review gate on template and URL changes, with a named person and a deadline. Programmes rarely fail because the strategy was wrong; they fail because a well-intentioned release shipped on a Thursday and nobody with search context saw it first.

Questions people actually ask

What makes an SEO engagement enterprise rather than just large?

Templates and stakeholders, not headcount. If most of your pages are generated by a small number of templates, changes must pass through an engineering release process, and legal or brand review sits between a recommendation and a live page, you are buying enterprise SEO regardless of company size.

Should we buy strategy only and execute in house?

Often yes, if you have writers and developer capacity. Advisory-only costs less and keeps knowledge in the building, but it only works when someone internal owns delivery and has the calendar to do it. Where that person does not exist, an advisory retainer produces recommendations that quietly accumulate in a backlog.

How long before an enterprise programme shows results?

Expect the first measurable movement once the first template-level changes actually ship, which is usually a function of your release cadence rather than the agency's speed. Ask candidates to forecast in terms of shipped changes rather than months, then hold them to the shipping rate.

Is a big-name firm worth the premium?

Sometimes, for procurement, security review and the ability to staff several markets at once. It is not worth it if the named senior people appear in the pitch and never again. Ask for allocation in days per month by named person, in writing, and the premium becomes checkable.
