What to Look for in an SEO Migration Consultancy: The Questions to Ask Before You Hire
The question that reveals more about a migration consultancy than any other is not on most people’s list.
Head of Search Intelligence & AI · Conversion Game
The question that reveals more about a migration agency than any other is not about their process, their case studies, their team size, or their pricing model. It is this: how does your migration process account for GEO and AEO readiness in 2026? The answer tells you everything. If they give you a specific, detailed answer — you are talking to someone who understands the current search landscape. If they hesitate or deflect — you are talking to someone whose migration process was built for 2022.
KEY TAKEAWAYS
The question that reveals a migration agency’s actual expertise is how they account for GEO and AEO readiness — a specific, detailed answer indicates genuine 2026 expertise
Most digital agencies have done migrations — fewer genuinely specialise in them — the distinction is the depth of knowledge about migration failure modes and how to prevent each one
Five questions before hiring: how many migrations personally overseen, most common failure mode and prevention, GEO and AEO process, post-migration monitoring scope, and a migration that went wrong
The account manager chain — the number of handoffs between brief and execution — is the most reliable predictor of migration failure regardless of individual competence
A genuine migration specialist delivers pre-migration audit, redirect map, staging validation, launch day protocol, and 30-day post-migration monitoring — not just the migration itself
Why most digital agencies are not migration specialists
There is a meaningful difference between an agency that has done migrations and an agency that specialises in migrations. Most digital agencies have done migrations as part of broader project scopes. The migration was a component of a larger project, not the primary expertise. A migration specialist is someone whose primary expertise is the migration itself — the redirect architecture, the authority transfer, the schema migration, the content preservation, the GA4 continuity, the post-migration monitoring.
The distinction matters because the failure modes in a migration are not obvious. They are the kind of thing that only becomes apparent after you have seen the damage they cause. A redirect chain that loses authority progressively with each hop. A canonical tag that prevents Googlebot from crawling the page it needs to crawl. A GA4 configuration that breaks at the migration boundary. These are not things a competent general-purpose developer would think to check. They are things a migration specialist checks automatically because they have seen the damage each one causes.
EXPERT NOTE
“The question that reveals more about a migration agency than any other is not about their process or their case studies. It is this: how does your migration process account for GEO and AEO readiness in 2026? If they know exactly what you are asking and give you a specific, detailed answer — you are talking to someone who understands the current search landscape. If they hesitate, deflect, or give you a generic answer about AI — you are talking to someone whose migration process was built for 2022.”
The five questions to ask before hiring a migration agency
Question one: How many migrations have you personally overseen from brief to post-migration sign-off? The emphasis on personally is deliberate — you are asking about the individual who will be leading your migration, not the agency’s collective history.
Question two: What is the most common way you have seen migrations fail and how do you prevent it? An answer that covers redirect maps, canonical tag misalignment, GA4 breakage at the migration boundary, staging noindex failures, and GEO visibility loss is an experienced answer.
Question three: How does your migration process account for GEO and AEO readiness?
Question four: What does your post-migration monitoring cover and for how long? If the answer is thirty days of rankings monitoring — you now know what is missing. User behaviour data, conversion rate signals, featured snippet monitoring, AI citation tracking, GA4 attribution verification, and crawl error monitoring all need to be part of the protocol.
Question five: Can you walk me through a migration that went wrong and how it was resolved? Every experienced migration specialist has cleaned up after something that did not go to plan. An agency that cannot describe a migration failure is either not experienced enough or not honest enough.
Red flags — what an agency says when they do not actually specialise
“We have done hundreds of migrations” — without being able to name the specific platform types, challenges encountered, or failure modes resolved. Volume without specificity is not experience. “Our process is fully documented” — accompanied by a process document that covers redirect mapping but does not mention GA4 continuity, canonical tag validation, schema migration, featured snippet protection, or GEO readiness. “We will monitor your rankings for thirty days” — without specifying what monitoring means, what data they will look at, what thresholds trigger action, and what actions they will take. “SEO is built into everything we do” — said by an agency whose primary expertise is design, development, or paid media.
Green flags — what a genuine migration specialist looks like
They ask for your Search Console data before quoting the project. A specialist who wants to understand what they are protecting before telling you how much it will cost is thinking about your migration correctly. They build the timeline backwards from go-live. A specialist who tells you a properly executed version of your migration takes twelve weeks and that the eight-week timeline your stakeholders want carries specific risks is being honest about the tradeoffs. They have a specific answer to the GEO and AEO question — not a general answer about AI being important, but a specific answer about entity architecture, schema implementation, AI citation baseline testing, and post-migration monitoring. They reference failure modes they have resolved personally.
The account manager problem
The most reliable predictor of migration failure is not the complexity of the migration. It is the number of people between the person who understands the requirements and the person who executes the work. In a standard agency model: the client briefs the account manager, the account manager briefs the project manager, the project manager briefs the developer. Each handoff is an opportunity for the most critical technical detail to be simplified, de-prioritised, or lost entirely.
Direct strategist access — where the person who understands the search requirements is also the person who validates the execution — eliminates this chain. Not because it is a more pleasant way to work. Because it is a more reliable way to prevent the handoff failures that cause ranking drops.
What a migration specialist should deliver
Before go-live: a pre-migration audit with complete URL inventory, traffic analysis, backlink profile summary, schema audit, featured snippet inventory, and AI citation baseline. A redirect map validated against the full URL inventory and prioritised by traffic value. A migration brief that specifies search requirements for every page type. A staging environment validation report confirming redirect configuration, canonical tags, schema implementation, GA4 tracking, and noindex status are all correct.
After go-live: 30-day active monitoring covering Search Console crawl errors, ranking position tracking against the pre-migration baseline, featured snippet position monitoring, GA4 attribution verification, AI citation tracking against the pre-migration baseline, and schema coverage verification in Search Console Enhancements. A 30-day post-migration report documenting outcomes against success criteria and specifying any remediation work required. The businesses that receive all of these deliverables are the ones that do not need a recovery project six months later.
FREQUENTLY ASKED QUESTIONS
How much should a website migration specialist cost?
Migration specialist costs vary based on site size, complexity, and the scope of services included. For a small site with under 500 URLs, a comprehensive migration engagement covering pre-migration audit, redirect map, staging validation, launch day oversight, and 30-day post-migration monitoring typically costs between $2,000 and $5,000. For a mid-sized site with 1,000 to 5,000 URLs the cost range is $5,000 to $15,000 depending on the complexity of the URL structure and the backlink profile. For large sites with over 10,000 URLs the cost range starts at $15,000 and scales significantly based on the complexity of the schema implementation requirements, the size of the redirect map, and the length of the post-migration monitoring period. These costs should always be evaluated against the value of the organic traffic being protected.
Should I hire an agency or an independent migration specialist?
The choice between an agency and an independent specialist depends on the scope of your migration project. If the migration is part of a broader redesign that also involves new design, new development, and new content, an agency that can handle all components under one brief may be more efficient even if their migration specialisation is less deep than an independent specialist. If the migration is the primary scope — you are moving platforms or domains without significantly changing the design or content — an independent migration specialist who focuses exclusively on the search performance of migrations may deliver better outcomes at lower cost. The most important criterion in either case is the same: the individual who will lead your migration should be able to demonstrate specific migration expertise through the five questions in this article, not just general digital marketing credentials.
How do I evaluate a migration specialist’s case studies?
Migration case studies should be evaluated on specificity rather than scale. A case study that says “we migrated a major ecommerce brand and maintained their rankings” is less informative than one that says “we migrated a Magento store with 12,000 product URLs to Shopify, implemented a 301 redirect map covering every indexed URL, rebuilt the schema stack from scratch, and maintained organic traffic within 5% of pre-migration baseline at the 90-day mark.” The specific details — the platform types, the URL counts, the specific challenges, the measurable outcomes — are what reveal genuine expertise. Ask for case studies from migrations that are similar in platform type, site size, and complexity to your own project.
What happens if my migration specialist makes a mistake?
The question of what happens when a migration specialist makes a mistake is as important as any other evaluation criterion — and most businesses do not ask it before hiring. A genuine migration specialist will have a clear answer: they have a monitoring protocol that detects problems in the post-migration window, they have an escalation process that activates when problems are detected, and they have a remediation process that resolves problems at no additional cost when they result from their own process rather than from scope changes or client decisions. Any specialist who cannot describe their error resolution process clearly has either not encountered migration errors — which is implausible for anyone with genuine experience — or has not built a systematic process for resolving them, which is a significant risk for your migration.
