A store with thousands of products faces search problems a brochure site never sees: duplicate pages created by filters, out-of-stock items, thin manufacturer descriptions and seasonal demand swings. That is why hiring an SEO agency for ecommerce is a different decision from hiring a general marketing firm. This guide, written with US online retailers in mind, explains what specialist work looks like and how to evaluate it.
Where ecommerce SEO differs
General SEO advice still applies, but online stores bring extra challenges:
- Faceted navigation: filters for size, color and price can create endless URL combinations that waste crawl budget and split ranking signals.
- Category pages: these often target the most valuable searches, yet many stores leave them as bare product grids.
- Product pages: copied manufacturer text means the same description appears on dozens of competing sites.
- Stock changes: discontinued and out-of-stock products need careful handling so you do not lose rankings or frustrate shoppers.
- Site migrations: platform switches, such as moving to Shopify or upgrading Magento, can wipe out traffic if redirects are mishandled.
An agency that has worked on large catalogs will raise these points without being asked.
What a specialist agency should deliver
Look for a plan that covers technical, content and commercial priorities together.
Technical health. Crawl analysis, canonical tags, structured data for products and reviews, page speed on mobile, and clean internal linking between categories and products.
Category and product content. Helpful intro copy on category pages, unique product descriptions for top sellers, buying guides that link to relevant collections, and FAQs drawn from real customer questions.
Merchandising alignment. Coordinating with your buying and marketing teams so seasonal categories are ready before demand peaks.
Feeds and shopping visibility. Many agencies also help keep product feeds accurate for free and paid shopping listings, which overlap closely with organic search.
Reporting that ties to revenue
For a store, rankings and traffic matter only as far as they drive sales. Insist on reporting that shows organic revenue, conversion rate and order value by category, not just keyword positions. Ask how the agency attributes sales when customers visit several times through different channels before buying. A good partner will be honest that attribution is imperfect and will focus on trends you can act on.
How pricing is usually structured
Ecommerce SEO is commonly sold as a monthly retainer, sometimes preceded by a paid audit. Larger projects, such as migrations or replatforming support, are often priced separately. Effort scales with catalog size, platform complexity, the number of markets and languages, how much content needs writing, and whether the agency also implements technical changes or hands them to your developers. Clarify who does the actual implementation, as that has a big effect on speed.
US privacy and platform considerations
Ecommerce tracking relies on analytics, pixels and customer data. State privacy laws such as the California Consumer Privacy Act require clear notices and, in some cases, opt-out mechanisms for sharing data with advertising partners. Your agency should make sure tracking respects these choices. Platform matters too: Shopify, BigCommerce, WooCommerce and custom builds each have different SEO strengths and limits, so ask about direct experience with yours.
Questions to ask before signing
- Can you show results on stores with a similar catalog size and platform?
- How will you handle faceted navigation on our site?
- Who writes product and category content, and how is quality checked?
- What will we see in monthly reports?
- How do you coordinate with our developers and merchandisers?
FAQ
Should I write unique descriptions for every product?
Start with your best sellers and highest-margin items. Writing original content for an entire large catalog at once is rarely practical, so prioritize where it will matter most.
What should I do with discontinued products?
It depends. Redirect to a close replacement or the parent category if one exists, or keep the page live with clear alternatives if it still attracts searches.
Do I need a developer for ecommerce SEO?
Usually yes, at least for technical fixes. Many retailers pair an SEO agency with a web development team, and some find one partner who handles both alongside digital marketing.
