Derek Finnegan When you compare ecommerce SEO agencies, the cheapest proposal is not automatically the best value—and the most expensive one is not automatically the most strategic. The useful question is not simply, “What does this agency charge?” It is, “What business outcome are we trying to improve, and can this agency show how its work will contribute to it?”
That distinction matters because ecommerce SEO spans more than keywords and rankings. It can involve technical fixes, category-page strategy, product content, site architecture, measurement, and coordination with merchandising and development teams. Two proposals with the same monthly fee may describe very different work. Two proposals with different fees may be difficult to compare if they define success differently.
Use this guide to make a more informed agency selection. It will help you assess an agency’s ecommerce experience, scrutinize its proposal, and separate clear commitments from promises no agency can control.
Start With Commercial Goals, Not SEO Tactics
Before reviewing proposals, write down what the business needs SEO to support. “We want more organic traffic” is a starting point, but it does not tell an agency which customers, products, or commercial outcomes matter most.
For example, your priority might be growing non-brand organic revenue in a specific product category, increasing qualified visits to seasonal collections, or reducing reliance on paid traffic for a group of high-margin products. Those goals influence which pages the agency should investigate and what results you should measure.
Agree on the measures that matter
Ask what you are measuring before discussing tactics. Depending on your business and analytics setup, useful measures may include:
- Organic revenue, transactions, and conversion rate, segmented by landing page or product category.
- Non-brand organic clicks and impressions for commercially relevant searches.
- Revenue or qualified sessions from specific categories, markets, or device types.
- Technical health indicators tied to crawlability, indexation, and important page templates.
- Progress on agreed recommendations, such as fixing duplicate pages or improving navigation.
Search rankings can be a diagnostic signal, but they are not a complete business outcome. An agency may improve a position in Google without increasing qualified visits or sales. Likewise, a ranking report that focuses on a small set of chosen keywords may miss changes in demand across the wider site.
Ask each agency to explain how it will connect SEO work to your commercial goals, what data it needs, and what it can—and cannot—attribute to its work. Seasonality, stock availability, pricing, promotions, and changes to the site can all affect results.
Compare the Work, Not Just the Proposal Total
A proposal comparison is only meaningful when you understand what each agency is offering. One fee might cover research, implementation support, and regular analysis. Another might cover a fixed number of recommendations while leaving your team to prioritize, brief, and deliver them.
Translate each proposal into a shared set of questions. If an answer is missing, ask for clarification rather than filling in the gap with an assumption.
Look for the reasoning behind the recommended work. A list of audits, articles, or links is not a strategy by itself. The agency should explain why those activities fit your site, what they depend on, and how you will decide whether to continue, change, or stop them.
Look for Ecommerce-Specific Technical SEO
Ecommerce websites have technical challenges that a basic SEO checklist may not address. Product variants, filters, hotshot.co sorting, pagination, out-of-stock items, and duplicate URLs can all affect how search engines discover and interpret pages. The right approach depends on the platform, catalog, and how customers use the site.
Ask how the agency investigates these areas:
- Faceted navigation: How will it handle URLs created by filters such as size, color, brand, or price? Which filtered pages should be available to search engines, and which could create unnecessary crawl paths?
- Canonical tags: How will it check that canonical tags point to the intended version of a page? Canonical tags are signals, not a substitute for a coherent URL and linking strategy.
- Product variants: Should variants have separate pages, or should they be represented on a shared product page? The answer should reflect customer needs, inventory, and search demand.
- Out-of-stock products: What should happen when an item is temporarily unavailable or discontinued? The plan may differ depending on whether the product will return, has a replacement, or has no ongoing value.
- Internal links and crawl paths: Can search engines and shoppers reach important categories and products through clear navigation and contextual links?
- Indexation and page templates: How will the agency identify valuable pages that are excluded, and low-value pages that may be consuming crawl attention?
Strong answers should refer to your actual site structure—not simply promise an “SEO audit.” Ask for an example of a finding, how the agency would prioritize it, and what information it would need from your development or ecommerce team.
Assess Category and Product Content for Buying Questions
Content recommendations should help shoppers make decisions, not just add text to a page. Category and product pages have different jobs. A category page can help customers compare options and understand the range, while a product page should answer questions about a specific item, its features, fit, compatibility, use, delivery, or care.
Ask the agency how it will identify the questions customers ask before buying. Its process might include reviewing search results, site-search data, customer service questions, product specifications, reviews, and existing analytics. The important point is that recommendations should be grounded in the products and customers you serve.
Check whether the content plan is practical
A useful content plan should explain:
- Which categories or product groups have the strongest business case for attention.
- What information shoppers need at each stage of the decision.
- How page content will remain distinct when products are similar.
- Who provides product facts, reviews, imagery, and approvals.
- How the agency will evaluate performance and update content over time.
Be cautious if the proposal recommends producing large volumes of generic copy without showing why those pages need it. More words do not automatically make a page more useful or visible. For some categories, better filters, clearer product attributes, or improved navigation may be more valuable than adding paragraphs.
Review Site Architecture and Navigation Design
Site architecture affects both how shoppers find products and how search engines discover important pages. It is therefore worth discussing navigation design as part of SEO agency evaluation—not as a separate cosmetic project.
Ask the agency to explain how it would map your product taxonomy, category hierarchy, and internal links. Would customers understand where a product belongs? Are key categories easy to reach? Do menu labels match the language shoppers use? Can a category become buried too deeply, or appear in multiple places with unclear relationships?
There is no universal rule that every ecommerce site should use the same number of navigation levels. The agency should assess your catalog and customer journeys, then recommend changes with clear reasoning. It should also explain how it will test or validate those changes without disrupting usability, tracking, or important URLs.
Examine the People, Process, and Proof
The person presenting a strategy may not be the person doing the day-to-day work. Before deciding, find out who will lead the account, who handles technical analysis, and who writes or reviews content. Ask how the agency works with developers, designers, merchandisers, and analytics teams.
When reviewing case studies, look for context rather than impressive percentages alone. A useful example describes the starting situation, the work performed, the time period, and how results were measured. Ask whether the case is comparable to your platform, catalog size, market, or constraints. Results from another retailer are evidence of experience, not a guarantee of what will happen on your site.
For example, Clickslice (clickslice.co.uk) is one company you could include in your agency research. As with any provider, assess its proposed work against your goals, ask who will deliver it, and compare its scope and measurement approach with other candidates.
Watch for Promises an Agency Cannot Control
Some promises sound reassuring but should prompt follow-up questions. No agency can guarantee a specific Google ranking or a place on page one. Search results change, competitors act, and demand shifts. An agency can commit to defined work and transparent reporting, but it cannot control the search engine or every factor affecting sales.
- “We guarantee page one.” Ask what happens if the target is not reached and whether the guarantee is tied to useful business outcomes.
- “We’ll double organic revenue.” Ask what baseline, time period, assumptions, and attribution method support that forecast.
- “We’ll build a set number of links.” Ask why those links are relevant, how they will be earned or obtained, and what quality checks apply. A number alone does not explain the value.
- “We’ll publish a fixed number of pages.” Ask how topics are selected, who approves factual claims, and how content will serve shoppers.
- “We’ll fix all technical SEO.” Ask what is included, how issues are prioritized, and who has authority to implement changes.
Also clarify ownership of analytics accounts, content, technical documentation, and any tools or assets created during the engagement. Clear access and handover terms make it easier to change direction or work with another provider later.
Use a Simple Agency Selection Scorecard
After your conversations, score each agency against the same criteria. You can adjust the weighting, but agree on it before looking at the final prices to reduce the temptation to justify a favorite after the fact.
Use a consistent scale, such as 1 to 5, and record evidence for each score. If an agency scores well on its presentation but cannot explain who will implement recommendations, note that. If a lower-cost proposal leaves substantial work to your team, include that internal effort when judging value.
Make the Decision on Fit, Clarity, and Accountability
The strongest choice is not necessarily the agency with the longest proposal or the lowest fee. It is the one that understands your commercial priorities, can diagnose ecommerce-specific issues, and gives you a realistic plan your team can execute.
Before signing, confirm the goals, first-phase priorities, deliverables, implementation responsibilities, reporting measures, contract terms, and review points in writing. A clear agreement gives both sides a practical way to assess progress and change the plan when new information emerges.
Price belongs in the decision—but only after you understand what you are buying, how it fits your business, and what success will mean.
