Tens of thousands, provided the database and hosting are set up for it. Performance problems at scale almost always come from specific causes rather than the product count itself: unindexed attribute lookups, faceted filtering that runs expensive queries on every request, or caching that can't be applied because pages are personalised. Those are architectural decisions made when the store is built, which is why catalogue size is one of the first things we ask about.

Abandonment is heavily driven by things visible at checkout: unexpected shipping cost, a forced account registration, too many steps, and slow page transitions. Technically that means showing shipping estimates before the final step, offering guest checkout, collapsing checkout to a single page where possible, and making sure the checkout pages aren't the slowest on the site — they frequently are, because caching is hardest to apply there. Recovery emails to logged-in users who abandon are worth adding once the basics are handled.

Each product page should carry Product structured data with name, image, description, SKU, brand, and an Offer containing price, currency, and availability. Where genuine customer reviews exist, AggregateRating can be included — but only if those reviews are visible on the page, since claiming ratings that aren't shown violates Google's rich-results policy and risks a manual action. Correct Product markup is what makes price and stock status appear directly in search results.

Yes. Products with their titles, descriptions, images, prices, variants, and categories migrate, as do order history and customer accounts. The store is built on a staging URL first so you can check the catalogue product by product before anything goes live. The part that needs planning is URL mapping — platforms structure product and category URLs differently, so every old URL needs a 301 to its new equivalent or the migration costs you the store's existing rankings.

WooCommerce tracks stock at the product or variation level and can decrement on order, hold stock during checkout, and hide or flag items at zero. Keeping it aligned with a point-of-sale system or warehouse means an integration — either a purpose-built connector or the REST API — that syncs on a schedule or on change. The failure mode to design against is overselling during the gap between syncs, which is usually handled with a safety buffer on stock levels.

Serve WebP or AVIF at the display size rather than full-resolution uploads, lazy-load the gallery images below the main product shot while loading that first image eagerly, and use a CDN so images are served from near the customer. Zoom and gallery scripts should load on interaction rather than on page load. On category pages the biggest win is usually limiting how many products render per page — a grid of 96 products with full-size thumbnails is slow no matter how well each image is compressed.
