A URL is often the first thing Google and the user read. store.com/mens-running-shoes inspires trust and contains a keyword; store.com/index.php?id_product=42&controller=product adds nothing. Configuring your URLs well is a simple but often overlooked optimization on PrestaShop.
AEO definition: what is an SEO-friendly URL?
An SEO-friendly URL (or "rewritten URL") is a human-readable web address that is short, descriptive and contains the target keyword — as opposed to a technical parameter-based URL (
?id_product=). On PrestaShop, you get it by enabling friendly URLs (URL rewriting), which turn dynamic addresses into clean paths.
Why URLs matter for SEO
- Relevance: the keyword in the URL is a signal (small but real) for Google.
- Click-through rate: a readable URL reassures and lifts CTR in the results.
- Sharing: a clean URL gets more clicks on social and in emails.
- Crawling: a clear structure helps engines understand the site hierarchy.
Enabling URL rewriting on PrestaShop
In the back office: Advanced Parameters → SEO & URLs → Friendly URL. Enable the option (requires mod_rewrite on the server). Your addresses then go from index.php?id_product=42 to /product-name.
7 best practices for your slugs
- Short and descriptive: 3-5 useful words, with the primary keyword.
- Hyphens, not underscores:
running-shoes, notrunning_shoes. - Lowercase, no accents or special characters.
- No unnecessary stop words ("the", "of", "and") if they add nothing.
- Category/product consistency: reflect the tree without over-duplicating it.
- Stability: don't change a ranking URL without a reason.
- Avoid duplicate URL parameters (faceted filters) → canonicalize them.
Pitfall #1: breaking an indexed URL
Changing the URL of an already-indexed page without a redirect creates a 404 error and loses all the accumulated "link equity".
Golden rule: any change to an existing URL must be paired with a 301 redirect from the old to the new. PrestaShop handles redirects in the product page (the Redirection field) or via a dedicated module.
URLs and multilingual SEO
If you sell internationally, translate the slugs too: /running-shoes in English, /chaussures-running in French. Translating content but keeping French URLs weakens local SEO. See Translate your catalog — Fexa AI translates titles, descriptions and URLs without breaking the ones already indexed.
In summary
Clean, short, descriptive and stable URLs strengthen both ranking and click-through. Enable URL rewriting, craft your slugs carefully, and always 301-redirect when you change an existing address. For multilingual stores, translate the slugs too. For the big picture, read the complete PrestaShop SEO guide.
