Three problems account for most of the loss
Faceted navigation generates crawlable URLs combinatorially. A category with six filters can produce thousands of near-identical pages, and crawlers spend their budget there instead of on the pages that matter. Deciding explicitly which combinations get indexed is usually the single highest-return technical change available.
Category pages are the second. They target the broadest commercial queries and are typically a heading above a product grid, competing against pages that explain how to choose. Adding genuine buying guidance is straightforward, and the pages are stable — the work does not need repeating when the catalogue turns over.
Product copy is the third. Manufacturer descriptions are published verbatim by hundreds of retailers, so nothing distinguishes yours. The differentiator has to be something you add: real reviews, honest fit notes, genuine photography, specifications the manufacturer omits.
How shoppers search
Most commercial demand is category-plus-qualifier rather than product name — a category with a size, a material, a use case, a constraint. Those queries map to filtered views, which is exactly why indexation policy for facets is a commercial decision rather than a technical footnote.
Comparison behaviour is heavy and mostly happens away from your site, on review platforms, video and increasingly assistants. A shopper asking a model which product suits their situation is served by whichever retailer's data the model can actually parse and trust.
Post-purchase search matters more than most retailers measure. Care instructions, compatibility, returns and troubleshooting queries reach existing customers, deflect support contacts and influence repeat purchase, and they are almost universally unserved.
Consumer rights, availability accuracy and claims
Consumer protection rules govern how availability, delivery and returns are presented, and inaccuracy here is a compliance matter rather than a UX one. Structured data that overstates availability or misrepresents delivery timing risks both enforcement and the loss of enhanced results when engines detect the mismatch.
Product claims — sustainability, origin, performance — face tightening scrutiny in several markets, with environmental claims a particular focus. Vague assertions that cannot be substantiated are exactly what regulators are now targeting, and they are also easy for a model to contradict from another source.
Review authenticity has become an enforcement priority. Incentivised reviews that are not disclosed, filtered review displays, and aggregate ratings that do not reflect all reviews create real exposure, and platforms have become considerably better at detecting them.
Where the weight sits
SEO carries most of the return in this sector. Crawl control, indexation policy and category depth are the binding constraints on almost every e-commerce site, and nothing downstream performs until they are resolved.
What goes wrong here
- Letting faceted navigation generate indexable URLs with no explicit policy
- Leaving category pages as a heading above a grid while optimising product pages
- Publishing manufacturer descriptions verbatim and expecting to outrank other retailers doing the same
- Marking up availability or delivery inaccurately, which is a compliance issue as well as a ranking one
- Deleting discontinued product pages instead of redirecting or repurposing them
- Ignoring post-purchase queries that retain customers and deflect support cost

Questions
Which filter pages should be indexable?
Those with genuine search demand and enough stock to stay populated. Combinations nobody searches should be blocked before crawlers reach them, and pages that are frequently empty are worse than no page at all.
How much content does a category page need?
Enough to help someone choose — how to pick, what the trade-offs are, which option suits which case. Placing it below the grid usually serves users better and works perfectly well for engines.
What should happen to discontinued products?
Redirect to the replacement where one exists, or keep the page with clear availability status and alternatives. Deleting it discards accumulated links and sends people arriving from search to an error.
Do we need unique copy for every product?
Prioritise by demand and margin. High-demand products justify original descriptions; long-tail catalogue items rarely repay it. Reviews, real photography and added specifications often differentiate more cheaply than rewriting prose.
