How to Vet E-Commerce SEO Companies for Shopify and WooCommerce Stores

Prices, platform behaviour and agency services change often, so confirm current rates, contract terms and platform limits directly with each provider before you sign.

Choosing among ecommerce SEO companies is hard because every pitch sounds alike: audits, strategy, "growth." What separates a good fit from an expensive mistake is whether the company has worked on stores like yours, on your platform, with proof you can check. This guide gives you a practical vetting process for Shopify and WooCommerce stores: what the work should cover, what to ask, what the money buys, and which warning signs to walk away from.

What should an e-commerce SEO company actually do for your store?

A good ecommerce SEO company works on the parts of a store that decide whether shoppers find products in search.

Category and product pages are usually the core service, since they carry the most commercial value. Link building, digital PR and content are often add-ons, so ask what sits inside the fee and what is billed separately.

Some stores need a technical clean-up and a category strategy. Others need ongoing content and links, or help with a platform migration. A company that does one of these well is not automatically right for another, so use a shared list to judge every proposal on equal terms. For the wider picture of how these pieces fit together, our roadmap to modern SEO explains what drives search visibility today.

Which platform experience matters for Shopify and WooCommerce?

Ask every candidate to show work on your platform, not just on "ecommerce" in general. Shopify and WooCommerce behave differently in ways that affect SEO.

• Shopify generates collection and product URLs on its own structure, handles canonical tags and redirects in particular ways, and limits how much of the theme code you can edit.
• WooCommerce gives you more control, but leaves more room for plugins, duplicate archive pages and slow databases to cause trouble.
• Magento and other platforms come up in many agency lists, so if you may replatform later, ask how the company handles a move.

A capable company explains these differences without prompting. Ask how they handle URL structure on your platform, how they manage redirects when a product is discontinued, and which apps or plugins they recommend and avoid. If the answers are vague, or identical for both platforms, treat that as a warning.

The strongest test is a short written audit of your own store before you commit. It shows how they think about your setup, and a firm that refuses to produce one, even a brief one, is telling you something about how it works.

What should an e-commerce SEO budget look like?

Price varies far more than most buyers expect, so an average on its own tells you little. Whito's UK research collected 45 published monthly SEO prices in June 2026: the median was £799, and half of them fell between about £410 and £1,500. Across six UK pricing guides, stated retainers run from £300 to over £25,000 a month, and hourly rates from £30 to over £400.

The more useful check is the arithmetic of hours. At £60 to £100 an hour, a £300 monthly retainer buys only three to five hours of work. That may be fine for a narrow task, but it will not stretch across a large catalogue. For comparison, Clutch's 2026 survey reports an average monthly SEO cost of $3,199, with project-based engagements averaging $37,158, typically reserved for website migrations, technical rebuilds or multi-market launches.

So do the sums yourself:

1. Take the monthly retainer and divide it by the agency's hourly rate to see the hours on offer.
2. Compare those hours with the size of your catalogue and the work you need done.

Ask each provider how many hours they expect to spend on your account each month and what those hours will cover.

Also ask whether the price includes content, link building and reporting, or whether each is an add-on. Many quotes look similar until you add the extras they left out. A transparent answer on hours and inclusions is worth more than a low headline price.

How do you check whether an agency's claims hold up?

Start with case studies, and read them critically. A useful one names the type of store, the platform, the starting point, the actions taken and the measured result, such as organic revenue or the number of category pages ranking for target terms. Be wary of studies that report only traffic growth without connecting it to sales, or that describe results on stores unlike yours in size, category or competition.

Client reviews help when they are specific. Look for reviewers who run stores on the same platform in a similar market. Ask for one or two references you can call, and ask those clients what they would do differently. Also check how long the company has kept its longest clients, because retention says more about delivery than a polished portfolio does.

Red flags repeat across the industry:

• Guaranteed rankings or first-place promises. No honest provider controls how search engines rank a site.
• "Secret sauce" methods described without any detail. A good company explains its process in plain terms and says what it cannot control.
• No access to your own data. You should see which pages changed and what rankings and traffic did, and be able to export the underlying data.
• One-size reports that show traffic but never revenue or the pages that were actually changed.
• Vague answers on who does the work, or a different team doing the work than the one that pitched.

Our guide on how to hire the right e-commerce SEO agency goes further on the hiring process itself.

What questions should you ask before you hire?

A short list of pointed questions tells you more than a long pitch deck.

1. Who does the work day to day? Is that person the one who presented to you?
2. How do you prioritise category and product pages? These usually drive the most value on a store.
3. What schema do you add? Product, review and breadcrumb markup are the usual starting points.
4. How do you handle redirects and migrations? Ask for an example from a past project.
5. What is in the monthly fee, and what costs extra?
6. How will I see results, and can I export my own data?

Ask about AI search too. Many companies now offer generative engine optimisation (GEO) or answer engine optimisation (AEO) alongside traditional SEO, aiming to make your products and brand easier for AI search tools to find and cite. Ask what they actually do, how they measure it, and whether it is a separate fee. Treat it as an addition to sound search fundamentals, not a replacement for them.

Agency size and specialism deserve a question as well. A small specialist may know Shopify apps and product feed quirks in depth, while a larger firm may offer more capacity for link building or multi-market work. Neither is better in general: match the firm to your stage. Ask what share of their clients are ecommerce stores, how many run on your platform, and which product categories they know, since seasonality, product copy and competition differ between fashion, home goods and electronics.

Finally, decide what stays in-house. If your team publishes product descriptions, buying guides or blog posts, you need a process that connects research, writing and publishing. Attela finds what people are searching for in your niche, writes the articles and the Instagram posts in your voice, and sends them to your site once you say yes. You can see how it is priced on the Attela pricing page.

Conclusion

Vetting ecommerce SEO companies comes down to a few disciplines: define the scope you need, check experience on your own platform, do the arithmetic on hours behind any budget, verify case studies and references, and walk away from guarantees and vague methods. Ask about technical depth, AI search and reporting you can take with you. The one that explains its work clearly and admits what it cannot control is usually the one to trust.

FAQ

How much do ecommerce SEO companies charge per month in the UK?

Prices vary widely. Whito's June 2026 research found a median published monthly price of £799, with half falling between about £410 and £1,500, while stated retainers across UK guides run from £300 to over £25,000. Compare providers by the hours and scope included, not the headline figure alone.

Is a £300 a month SEO retainer enough for a Shopify store?

It depends on the scope. At typical rates of £60 to £100 an hour, £300 buys only three to five hours of work a month. That may suit a narrow task, but a larger catalogue usually needs more time. Ask for the expected hours and the specific deliverables before you decide.

Should I choose an agency that specialises in Shopify or WooCommerce?

Platform experience helps, because the two systems handle URLs, redirects, canonical tags and apps differently. Ask each company how it manages these on your platform and request a short audit of your own store. Generic answers that apply equally to both platforms are a warning sign.

What is the difference between SEO and GEO or AEO for ecommerce?

Traditional SEO focuses on ranking in search results. Generative engine optimisation (GEO) and answer engine optimisation (AEO) focus on how AI search tools find, summarise and cite your products and brand. Good companies treat these as an extension of solid SEO fundamentals and can explain how they measure them.

Can an ecommerce SEO company guarantee first-page rankings?

No honest company can guarantee rankings, because search engines control them. A guarantee is a red flag. Look instead for a clear process, realistic forecasts and reporting that connects the work to traffic and revenue.

What questions should I ask an e-commerce SEO company before hiring?

Ask who does the day-to-day work, how they prioritise category and product pages, how they handle faceted navigation, schema and redirects, what the monthly fee includes, and whether you can export your own performance data. Also ask for references from stores similar to yours.

How do I check an agency's case studies?

Look for the store type, platform, starting point, actions taken and a measured result, ideally tied to organic revenue rather than traffic alone. Then ask for a reference you can call, and ask that client what they would change about the work.

Do I need an agency for content, or can my team handle it?

It depends on your capacity. Many stores keep product copy and blog content in-house and outsource technical and strategic work. A content platform can help with research, drafting and publishing, but it does not replace technical SEO or link building, so decide which parts you need covered before you compare companies.
