What is the most important page type for ecommerce SEO?
Category pages. They target the terms with the most volume, and on most stores they are a product grid with no text at all. Adding real content to them usually outperforms any amount of product page work.
How do we handle filters and faceted navigation?
With canonicals, parameter handling and selective noindex, so filter combinations do not generate thousands of near-duplicate indexable URLs. Uncontrolled facets are how a store with two hundred products ends up with forty thousand URLs and wasted crawl budget.
Should we write our own product descriptions?
Yes. Manufacturer descriptions are identical across every retailer selling the same item, which gives search engines no reason to prefer your page. Unique descriptions that answer real objections do.
What should we do with out-of-stock products?
Keep the page, mark it unavailable and suggest alternatives, or redirect to the closest match. Deleting throws away a page that may have taken months to rank, and the URL usually still has links pointing at it.
Can we add review stars to search results?
With genuine reviews and correct Product schema, yes. Fabricating ratings is structured data spam and among the most reliably penalised things you can do, so it needs real reviews first.
How long does ecommerce SEO take?
Three to six months for category and product pages to move, longer in competitive categories. Technical fixes such as faceted navigation control can show faster because they free crawl budget that was being wasted.
