How to choose an ecommerce SEO agency (and red flags to avoid)

The short answer

Look for platform-specific technical knowledge (Shopify or WooCommerce, not generic SEO), a clear explanation of what gets audited before any work starts, reporting tied to organic revenue rather than rankings alone, and pricing attached to defined deliverables instead of a vague monthly retainer. The red flags further down tend to cost stores more than the fee itself.

What an ecommerce SEO agency should actually do

Before comparing agencies, it helps to know what the job involves. For an online store, good SEO work usually covers:

• Technical health: crawling and indexing, duplicate URLs from filters and variants, site speed, mobile experience and structured data.
• Category and collection pages: matching them to what people search for, and giving them enough useful content to rank.
• Product page templates: titles, descriptions, images, reviews and schema, improved at the template level so the fix applies across the catalog.
• Internal linking: making sure authority flows from the homepage and categories to the products that matter commercially.
• Supporting content: buying guides and comparisons that answer questions category pages cannot.
• Authority: earning links and mentions through legitimate means such as PR, partnerships and genuinely useful content.

An agency whose proposal covers only one of these — usually blog posts or links — is solving part of the problem.

Why generic SEO agencies often underperform for ecommerce

A content-focused SEO agency that mainly writes articles and builds backlinks is working on a different problem from the one most stores actually have. Product and category structure, faceted navigation, variant duplication and performance across a large catalog are ecommerce-specific issues a generalist may never have diagnosed. The result is a lot of activity on the blog while the pages that generate revenue stay where they were.

Know your own numbers before the first call

You will judge proposals far better if you arrive with a baseline. It takes an hour to collect:

• organic revenue and orders for the last twelve months, from your analytics;
• clicks and impressions from Google Search Console, split between searches that include your brand name and those that do not;
• your top twenty landing pages from organic search;
• your platform, theme, number of products and any major changes planned in the next year.

An agency that asks for this data before quoting is a good sign. One that quotes without looking at anything is pricing a package, not your store.

Ask what “audit” actually includes

A real technical audit is specific. It should cover:

• indexing: which pages are indexed, which are not, and why;
• duplicate and low-value URLs generated by filters, sorting, variants and tags;
• page speed and Core Web Vitals on real product and category templates, not just the homepage;
• category architecture compared against keyword research;
• structured data on products, reviews and breadcrumbs;
• internal linking and orphaned products;
• a prioritized list of fixes with the reason for each.

If the answer is vague, or the sample audit reads the same for every store, it is probably a template report. Our guide on what to expect from a technical SEO audit explains how to tell the difference.

Ask for platform-specific experience

Shopify and WooCommerce fail in different places, and general SEO knowledge does not automatically cover either.

• Shopify: products reachable through several collection paths, thin tag and collection pages, apps injecting scripts on every page, and limits on URL structure and robots rules that need workarounds rather than wishes.
• WooCommerce: filter and sorting parameters, plugin bloat, hosting not sized for a store, and several plugins outputting conflicting product schema.

Ask for examples of stores they have worked on using your platform, and what they changed. Our Shopify SEO mistakes and WooCommerce SEO checklist are useful references for the conversation.

Product and category pages

Category pages are usually the highest-value pages on a store for competitive, high-volume searches, yet they are often thin and templated. Product pages suffer from manufacturer descriptions duplicated across the web, missing schema and oversized images. A good agency treats both as the priority and improves them at template level, so hundreds of pages benefit at once. If none of this comes up in the first conversation, ask directly.

How they earn links and mentions

Links still matter, but how they are earned matters more. Legitimate approaches include digital PR, supplier and manufacturer listings, partnerships, and content that others genuinely want to reference. Buying links, private blog networks and mass-produced guest posts break Google’s spam policies and can leave a store with a problem that takes months to clean up. Ask exactly where links will come from and ask to see examples.

Reporting that connects to revenue

Rankings are an input, not a result. Useful reporting shows organic revenue and orders, non-brand clicks from Search Console, the performance of the specific pages that were changed, and what was done that month. A report made only of ranking positions and traffic graphs makes it impossible to tell whether the work is good or the numbers simply moved with the season.

Red flag: guaranteed rankings

No one controls Google’s algorithm. An agency promising a specific position or timeline is either guessing or planning shortcuts that eventually hurt you — keyword stuffing and low-quality links still turn up in “guaranteed ranking” packages.

Red flag: no visibility into the work

You should be able to see exactly what changed on your site and why. If the agency will not share a change log, or makes changes through accounts you cannot access, you cannot judge the work or take it with you later.

Red flag: one-size-fits-all packages

A 500-product store and a 15-product store do not need the same SEO work. A flat package sold identically to every client usually means the audit step is theater rather than diagnosis.

Red flag: they own your accounts or content

Your Search Console, analytics, content and any tools set up for your store should belong to you, with the agency added as a user. Contracts that keep ownership with the agency, or lock you in for a year before any results can be judged, protect the agency rather than you.

Red flag: content at industrial scale

Publishing hundreds of thin, automatically generated pages to target every keyword variation is not a strategy; Google treats scaled, low-value content as spam. More pages is not the goal. Better pages that match real searches is.

What good pricing looks like

Either a fixed project fee tied to specific deliverables — audit, fixes, content plan — or a monthly retainer with a documented scope of what each month includes. Many stores do best with a hybrid: a fixed-price audit and implementation first, then a smaller retainer for ongoing work once the foundations are fixed. Be wary of any number with no explanation of what it buys.

Questions worth asking directly

• What will you audit in the first two weeks? A good answer names specific checks and your platform’s known issues.
• Which of my category or product pages would you change first, and why? A good answer references your data, not a generic plan.
• How will you measure success beyond rankings? Look for organic revenue, non-brand clicks and page-level results.
• Where will links come from? Look for specific, legitimate sources.
• Can I see an example audit from a similar store? Names can be removed; the depth should be obvious.
• Who will actually do the work? Ask whether the person on the sales call is involved after you sign.

Confident, specific answers are a good sign regardless of price. A vague answer to any of them is worth pausing on.

Comparing proposals side by side

When you have two or three proposals, put them next to each other and check: does each one reference your store’s actual data? Does it list deliverables rather than hours? Does it say what happens in months one to three? Does it explain how success will be measured and reported? Does the contract let you leave with your data and content? The cheapest proposal is rarely the one that answers all five.
