How we compare ecommerce SEO companies

1. Check for real store experience on your platform. Shopify, Magento, BigCommerce and custom builds fail in different ways. We look for named clients on the platform you run and for evidence the firm has shipped technical changes there, not just published blog posts alongside somebody else's development team.
2. Look for category page work, not blog output. Most commercial search in retail lands on category and filtered pages. A firm whose portfolio is entirely articles has been optimising the least valuable part of the site. Ask which category pages they rewrote for a client and what happened to revenue from them.
3. Test their handling of duplication and faceted navigation. Filters, sorts and variants generate near-identical URLs at scale, and how a firm handles canonicalisation, indexing rules and internal linking decides whether a large catalogue is an asset or a mess. Ask them to describe their approach before you mention your platform.
4. Require revenue reporting, not session reporting. The measure is organic revenue and margin by category, not sessions. We look for firms that report that way by default and for proposals that name the categories they intend to grow rather than promising a sitewide traffic percentage.

What the work actually consists of

A serious engagement spends most of its effort in four places. Architecture, meaning the category structure, internal linking and the rules that decide which of thousands of URLs should be indexed at all. Category and product content, which is where commercial searches land and where thin manufacturer descriptions repeated across the web quietly cap your ceiling. Technical performance, since large catalogues are slow by default and speed on mobile is both a ranking input and a conversion one. And product data consistency, because the same information feeds your pages, your shopping listings and your marketplace presence; Google publishes a product data specification for the feed side and a product structured data specification for the pages, and a store where the two disagree loses eligibility for the richest results.

What matters less than agencies imply is publishing volume. Buying guides and comparison content have a place, particularly for products that need explaining, but they are a supplement to the commercial pages rather than a replacement for fixing them.

What moves the fee, and how to compare quotes

Catalogue size is the first driver, because a few hundred products is a different job from tens of thousands of variants. Platform is the second: a locked-down hosted store limits what can be changed and can make some fixes impossible without development work, while a custom build gives freedom and adds risk. Competition in your category is the third, and it is a fact about your market rather than about the agency. The fourth is whether development capacity is included: a great technical audit that your team cannot implement is an expensive document, and firms that ship the fixes themselves cost more and are usually worth it.

Compare quotes on stated output rather than fee. Ask each candidate what will be different on the site after ninety days, in specifics: which categories rewritten, which indexing rules changed, which template fixed. Then ask what they need from your team to do it, since the most common cause of a failed retainer is not a bad agency but a queue of recommendations nobody had time to implement.

Questions people actually ask

How long does ecommerce SEO take to move revenue?

Technical and indexing fixes can move things within weeks because they change how much of the catalogue is visible at all. Category content and authority work run on a longer cycle, commonly a couple of quarters. Seasonality complicates the read, so compare against the same period last year rather than against last month.

Should the agency write product descriptions?

For your important products, yes, because manufacturer copy repeated across every retailer gives search engines no reason to prefer your page. For a long tail of thousands of low-value items it is rarely economic. Agree which tier gets written work and what happens to the rest.

Do I need structured data on product pages?

It is how search engines read price, availability and reviews reliably, and it is what makes richer result formats possible. Get it right and keep it consistent with your shopping feed, since contradictory data across the two is a common and avoidable cause of lost eligibility.

Is an ecommerce specialist worth more than a general agency?

Generally yes, if the specialism is real. Ask for store clients by name, ask what platform work they have shipped, and ask how they handle faceted navigation. A general agency that answers those three well is fine. One that redirects to content strategy is telling you which half of the job it does.
