Ecommerce SEO Migration Audit: What to Check Before Launch

An ecommerce SEO migration audit should tell your team exactly what search value exists today, what the new store changes, which URLs and templates are at risk, and how to prove the launch worked. A generic crawler score is not enough. Our ecommerce SEO audit can be scoped around a planned migration so the findings become a redirect map, launch checks and named decisions.

Quick answer: commission the audit before the new URL structure and theme are frozen. Expect five deliverables: a baseline of valuable landing pages, an old-to-new URL map, a comparison of source and destination templates, a launch test plan, and post-launch monitoring by page group. Confirm who will implement each recommendation and who can stop launch if a critical check fails.

When is a pre-launch audit worth paying for?

It is most valuable when an established store has organic revenue, a large catalogue, several markets, complex filters, a content library or a platform change that alters paths. A brand-new store with no existing search footprint still needs launch QA, but it may not need a large migration audit.

The cost of discovering a missing redirect map after launch is not limited to rankings. Customers can follow old links into errors, marketing campaigns can break and developers may have to reconstruct source data under pressure. The audit buys a controlled inventory and a decision process before those changes go live.

Deliverable 1: the source-site baseline

Ask for a joined export of a full crawl, XML sitemaps, Search Console landing pages and queries, analytics revenue by landing page, top linked URLs and important campaign pages. A crawl alone misses orphaned URLs; Search Console alone misses pages that customers still visit through bookmarks or email.

Every record should include its old URL, page type, status, canonical, organic clicks, revenue or lead value, backlinks where available and last-seen date. Segment products, categories, articles, brand pages and policies. The baseline lets you tell whether a later decline is concentrated in one template or spread across the store.

Deliverable 2: a reviewed URL map

The map should connect each valuable old page to a new URL and state the action: unchanged path, permanent redirect, consolidation or retirement. Include the reason for difficult decisions. A discontinued product may redirect to a close successor; a useful comparison guide should retain its answer rather than redirect to the homepage.

Google’s site move guidance recommends mapping URLs, testing redirects and avoiding irrelevant destinations. It also recommends maintaining redirects for at least one year, generally longer where possible. The audit should calculate redirect coverage for high-value pages, not report only the total number of rules created.

Deliverable 3: source-to-destination template comparison

Choose representative products, categories, articles, pages and market versions. Compare old and new title, H1, body content, internal links, canonical, robots directive, product markup, image context and rendered HTML. Add a sample of variants, sale prices and out-of-stock products because those often behave differently from the default template.

The output should say what changed and whether it is intentional. A prettier collection that loses the selection guidance earning search demand is not equivalent just because the products imported. A product page with the correct name but stale price schema is not ready for sign-off.

Deliverable 4: a launch test plan with owners

Names matter more than job titles. “The agency will check” is vague if the platform team controls DNS and the SEO team cannot deploy redirects. The audit should include a launch blocker list and a rollback decision owner.

Deliverable 5: monitoring after launch

Set up a daily technical check for the first days: old URL redirects, 404 and 5xx errors, top destination pages, robots and canonicals, sitemap availability, checkout and analytics. Then review Search Console clicks, impressions and indexation by page group each week against the baseline.

Google says ranking fluctuation can occur while a site move is processed. Monitoring should distinguish that from a concentrated problem such as all categories choosing the wrong canonical. Provide a threshold and escalation route for each critical group rather than one promise to “watch rankings.”

What the audit should inspect on Shopify

For a move to Shopify, inspect /products/, /collections/, /pages/ and blog routes, plus legacy paths from the old system. Check how collection navigation links to products, how variants are represented, which app emits Product markup, and whether Shopify Markets changes the destination by country.

Shopify’s WooCommerce migration guide describes redirect creation and its automatically generated sitemap. Those features still require a reviewed map and live validation. The directional WooCommerce to Shopify migration checklist covers the platform-specific sequence.

What the audit should inspect on WooCommerce

For a move to WooCommerce, confirm the permalink bases, category hierarchy, hosting performance, plugin ownership, sitemap generator, canonical output and structured data. Test whether the old Shopify domain and paths can be redirected by the new host when Shopify no longer serves requests.

WooCommerce’s migration documentation calls out 301 redirects, metadata checks and staging tests. Use the Shopify to WooCommerce SEO migration guide to translate those controls into page-level acceptance tests.

Questions to ask the provider before approving scope

1. Will you use Search Console and revenue data or only crawl software?
2. Will the map include legacy redirects, blog posts and top backlink destinations?
3. Who decides whether a discontinued URL redirects or remains a 404?
4. How will you compare source and destination content?
5. Which product variants and markets are in the test sample?
6. Can you test redirects before public launch?
7. Who deploys fixes and how are they verified?
8. What specifically blocks launch?
9. How long does post-launch monitoring continue?
10. What is excluded from the quote?

A provider who cannot answer implementation ownership may still offer useful advice, but your team must assign someone to act on it. Read the audit versus monthly SEO comparison if the project needs ongoing release coordination.

Red flags in an audit proposal

• It promises no ranking fluctuation.
• It ignores pages with backlinks or historic revenue.
• Every old URL is sent to the homepage.
• It checks only the homepage and a default product.
• It counts redirects without testing their destinations.
• It does not inspect analytics and checkout.
• It provides recommendations without owners or acceptance tests.
• It assumes a migration plugin transfers SEO metadata correctly without sampling.

These are decision failures, not missing decorative report sections. A concise audit with a complete priority URL map and a test plan can be more valuable than a hundred-page tool export.

How much should an SEO migration audit cost?

The scope depends on URL count, platform complexity, markets, custom integrations, content library and how much implementation or post-launch monitoring is included. Ask for a fixed list of deliverables and sampled templates before comparing quotes. A small audit of one storefront is a different project from a multi-market replatforming with thousands of redirects.

Our pricing page shows current entry points for ecommerce SEO work. A specific migration receives a confirmed scope and quote. The key comparison is whether the proposal funds mapping, QA and correction rather than only a pre-launch report.

When to book the audit

Book it before finalizing navigation, URL patterns and the content import rules. Those decisions become expensive to reverse later. Bring the planned launch date, current platform, new platform, catalogue size, priority markets, Search Console access and the latest destination crawl if one exists.

For a store already live and losing visibility, use our post-migration traffic diagnostic to identify the failed page group, then send the findings through the contact page. A confirmed single defect may fit a focused fix; a missing baseline calls for the broader audit.

FAQs

Is an SEO audit necessary before every platform migration?

A new store with no historic search footprint may need only launch QA. An established store with organic sales, links, content or multiple markets benefits from a baseline and reviewed URL map before changing platforms.

Can a developer do the migration audit?

Yes if the developer can combine search and commercial data with technical checks and page-intent mapping. The important requirement is named ownership of the decisions and tests.

Will an audit guarantee the same rankings after launch?

No. It reduces avoidable errors and establishes evidence for recovery. Google may temporarily change rankings while it recrawls and processes a significant move.

Should old product URLs redirect to categories?

Only when the category closely satisfies the old product intent and no better replacement exists. A direct successor product is usually clearer. Unrelated homepage redirects can confuse users and search engines.

What should I send to an SEO migration specialist?

Send the platform pair, launch date, sitemap, top organic landing pages, catalogue size, markets, proposed URL structure and any existing redirect sheet. Those inputs reveal the real scope.
