Ecommerce traffic declines have causes that brochure sites do not, and checking those first saves working through generic SEO explanations that do not apply. Catalogues change constantly, and most of what changes can affect visibility.
The general diagnostic sequence is on why organic traffic dropped. This page covers what is specific to stores.
Check the catalogue before checking SEO
On a store, the most common causes are merchandising decisions that nobody thought of as SEO changes.
- Products went out of stock and the template hides them, emptying categories. See out-of-stock products.
- Products were discontinued and their URLs now 404 without redirects. See discontinued products.
- Categories were restructured, changing URLs without redirects.
- A supplier or range was dropped, removing a section that was earning traffic.
- Seasonal products were unpublished rather than marked unavailable, destroying their accumulated position.
None of these looks like an SEO change from the inside, which is why they are missed. Check the merchandising log alongside the deployment log.
Then check the technical layer
- Filter handling changed, either flooding the index or removing URLs that were ranking.
- An app or plugin was added or removed, altering markup, rendering or internal linking.
- Product markup broke, withdrawing rich results and reducing click-through even where position held. See product schema SEO.
- Site speed regressed, usually on category templates, which are the heaviest and the most commercially important.
- A migration or replatform occurred, in which case that is the first suspect. See ecommerce platform migration.
Then the ecommerce-specific external causes
- A marketplace or retailer started stocking your products, outranking you on your own product terms.
- The manufacturer began selling direct.
- Results shifted toward Shopping and away from organic, reducing organic clicks at unchanged positions.
- Competitors improved product content on the same catalogue you both sell.
That last one is worth taking seriously if you use manufacturer descriptions. When a competitor writes original content for the same products, they have something you do not.
Segment before concluding
- Category pages versus product pages. A drop confined to one is highly diagnostic.
- Branded versus non-branded queries. Branded decline is usually demand, not SEO.
- New products versus established ones, which separates indexing problems from ranking ones.
- Compare year on year, since retail seasonality is pronounced and easily misread.
Frequently asked questions
Traffic fell but rankings held. Why?
Often Shopping results absorbing clicks, or rich results withdrawn because product markup broke. Both reduce clicks at unchanged positions and neither is a ranking problem.
Category pages dropped but products are fine. What does that mean?
Usually a category template or structural change: content removed, filter handling altered, or categories emptied by out-of-stock rules. Look at what changed on that template.
Could this be seasonal?
Very possibly. Retail seasonality is stronger than in most sectors. Compare against the same period last year before treating it as a fault.
We removed old products and traffic fell. Is that related?
Almost certainly. Removed URLs without redirects lose whatever they had accumulated, and if they were internally linked their removal also affects the pages that linked to them.
