Shopify SEO & CRO audit for premium brands, London
Technical SEO, site speed, conversion and AI visibility, checked by hand and ranked by what costs the most.
A fixed-scope ecommerce SEO and CRO audit for premium Shopify stores. Three tiers from £600, delivered in 3–8 working days. Each audit is carried out end to end by a Shopify SEO consultant in London, and the fixes can then be booked by the hour or month to month, with no contract.
What to fix first
Most Shopify stores have four problems at once. Usually one is costing the most.
Automated tools flag signals, not priorities.
A PageSpeed report or a crawler audit produces 150 line items with no ranking. Useful as raw data, weak as a brief.
Most audits arrive without a price or a scope.
Many Shopify audit offers ask for a call before showing what the work covers, how long it takes or what it costs. Here all three are on the page: four areas, 3–8 working days, from £600.
A founder needs a brief, not a checklist.
A useful audit is reviewed end to end by one person, ranked against the store's commercial situation and written so a developer can act on it directly.
What The Audit Covers
Four areas. The same lens at every tier.
Every audit assesses the same four areas. The tier sets the depth and what you receive: Conversion Audit (3 working days, from £600), Visibility Audit (5) or Full Store Diagnostic (8), priced on request.
FAQ
How much does a Shopify SEO audit cost?
At Treff Labs, the Conversion Audit starts at £600. There are three tiers, so an early brand that needs one area checked does not pay for a full diagnostic, while a brand about to invest in a rebuild gets the whole picture. The Visibility Audit and Full Store Diagnostic are priced on request. If unsure which level fits, a free intro call of up to 30 minutes helps decide.
Can ChatGPT or a free SEO tool do the audit?
Partly. Free tools and ChatGPT can flag technical signals, such as broken links, missing meta descriptions and slow pages, and comment on the pages they are shown. Without a full crawl of the store, Search Console data and a test of the checkout, they cannot tell which issues matter for a premium brand at its stage, or what to fix first. That judgement is what the audit adds.
How long does a Shopify audit take?
Conversion Audit: 3 working days. Visibility Audit: 5 working days. Full Store Diagnostic: 8 working days. The clock starts when the store URL and a short brief arrive.
Do you audit Shopify Plus stores?
Yes, if the brand is a premium, founder-led business. The audit is designed for premium brands, not for enterprise Plus teams with their own developers.
Does the audit cover AI visibility (ChatGPT, Perplexity, Google AI Overviews)?
Yes. AI and LLM visibility is included as standard in the Visibility Audit and Full Store Diagnostic. The audit checks six layers: technical AI-readiness, structured data, answer-ready content, entity and brand authority, prompt-oriented topic coverage and live AI presence monitoring across ChatGPT, Perplexity, Gemini, Bing Copilot and Google AI Overviews.
Is the audit fee really credited against a project?
Yes, in full. If you commission a development, SEO or performance project within 90 days of receiving your audit, the full fee is deducted from the project cost. The audit becomes the scoping document, so charging it twice would make no sense. After the audit, fixes can be booked by the hour or month to month, with no contract.
What format is the report?
A written document: PDF or Notion doc, your preference. Structured into fix now / fix next / long-term. Not a slide deck. Not an automated tool export. Designed to hand directly to a developer or act on yourself.
Do you work with US brands?
Yes. The audit is delivered remotely, so it works the same for brands in the UK, Europe and the US. US brands make up a meaningful share of enquiries, and US Shopify stores tend to have the same structural issues as UK ones. Prices are set in GBP; the USD equivalent follows the current exchange rate.
What do you need from me to start?
Your store URL and a brief note on what you believe is not working — two or three sentences is enough. Read-only GA4 access is helpful but not required. No brief document is needed. A free intro call of up to 30 minutes is available if it helps decide which level fits.
