Key takeaways
- PrestaShop is sound at its core, but the default settings let the index fill up: crawlable facets, empty category pages, duplicated manufacturer descriptions.
- Faceted navigation is job number one: a category of 50 products can generate thousands of near-identical filtered URLs.
- A manufacturer description pasted as-is puts you in direct competition with every store selling the same product, on strictly identical content.
- Stockouts and discontinued lines get a 301 to an equivalent, never a hard delete: every 404 throws away accumulated signal.
- Category pages are your real SEO landing pages: they are the ones that can win high-volume generic queries, not your product pages.
PrestaShop remains one of the most popular ecommerce platforms in Europe, and the stores running on it share one trait: they all accumulate the same SEO problems, in the same places. Good news, that makes the audit very systematic. A PrestaShop SEO audit is the foundation of a complete SEO audit applied to the quirks of this specific CMS: facets, product pages, stockouts, multilingual setups. This guide walks through the 7 work areas in the order they cost you traffic, with the exact PrestaShop settings to check. Whether your store carries 200 or 20,000 SKUs, the list is the same. Only the scale changes.
Step 1: URLs and base configuration
Head to Shop Parameters, Traffic & SEO. Three quick checks.
Friendly URLs must be enabled. Without them, your URLs carry unreadable technical parameters. With them, you get clean URLs like /category/product. If you flip the Friendly URL switch on an existing store, PrestaShop handles the redirects, but spot-check a sample afterwards.
One canonical domain. The store should respond on a single combination (with or without www, always https) and 301 every other variant. PrestaShop's canonical URL setting must be on "301 Moved Permanently", not "No redirection".
The sitemap must exist and stay clean. Generated by the native module or a dedicated one, submitted in Google Search Console, and above all containing only pages that return 200: no disabled products, no filtered URLs.
Step 2: faceted navigation, the silent flood
This is the ecommerce problem par excellence, and PrestaShop is not spared. Every filter in the faceted navigation (size, color, price, brand, availability) generates a URL. Combinations multiply against each other: a category of 50 products with 5 filters can produce thousands of URLs, all near-identical, all crawlable.
The damage is twofold. Google burns your crawl budget on worthless pages instead of visiting your new arrivals, and your index fills with duplicates that dilute your signals. The classic symptom in Google Search Console: tens of thousands of pages flagged "Discovered, currently not indexed" or "Alternate page with proper canonical tag" while your store carries 800 products.
The triage strategy:
| Facet type | Example | Treatment |
|---|---|---|
| Facet with real demand | "convertible corner sofa" | Dedicated indexable page with its own title and content |
| Utility facet | sort by price, availability | Noindex, plus crawl blocking if the volume gets huge |
| Multiple combinations | color + size + price | Systematic noindex |
The decision rule: if people type the combination into Google (check the search volumes), it deserves a real page. Otherwise it has no business being in the index. Depending on your PrestaShop version and your facets module, the control happens through the module settings or a dedicated SEO module.
Step 3: stockouts, discontinued lines and deleted products
A store lives: products go out of stock, references get discontinued, catalogs rotate with the seasons. Every mishandled case throws SEO signal in the trash.
Temporary stockout: the page stays live, returning 200, with a restock date if possible and alternative products in plain sight. Do not disable it: you would lose the ranking, and recreating the page later starts from zero.
Permanent discontinuation with an equivalent: 301 redirect to the replacement product or the parent category. PrestaShop handles this natively from the product page (the "Redirection when offline" setting). It is the most underused feature in the whole back office.
Permanent discontinuation with no equivalent: a deliberate 410 (or 404), and the page comes out of the sitemap and the internal linking.
The audit itself means crawling the store and cross-referencing with Search Console: how many 404s have piled up, which ones had rankings or backlinks, and where each should redirect. On a store that has been trading for a few years, this single work area often recovers meaningful traffic.
Step 4: duplicate content, the product page plague
Two massive sources of duplication on PrestaShop.
Manufacturer descriptions. You import your catalog with the copy supplied by your suppliers, exactly like the 40 other stores selling the same references. Google ends up with 40 pages of identical content and no reason to prefer yours. The fix is editorial: rewrite, starting with the highest-stakes products. It takes time, which is why AI-assisted writing changes the economics here: you produce unique descriptions at catalog scale and keep the final review for yourself.
Variants and internal duplicates. The same product reachable through several category paths, variants generating their own URLs, forgotten printable or AMP versions. The check: every product must have a single canonical URL declared via rel=canonical, and every variant must point to it.
Step 5: category pages, your real SEO landing pages
Here is the point almost every store misses. Your product pages target precise queries ("product name"), but the high-volume queries are generic ones ("grain-free dog food", "fabric corner sofa"). And those queries are the ones your category pages can win.
A default PrestaShop category page is a title and a grid of products: nothing to index. For each strategic category, the audit checks: a title tag and H1 aligned with the target query, a substantial category description (not three decorative lines, real content that answers the intent), internal links to subcategories and flagship products, and clean pagination.
This is the direct extension of keyword logic: each category targets one query, each query gets one page. If two categories chase the same intent, you create keyword cannibalization between your own pages.
Step 6: speed, modules and images
PrestaShop stores collect modules the way WordPress sites collect plugins, with the same result: product pages that take 6 seconds to load on mobile.
The protocol: measure mobile LCP on your three templates (homepage, category, product), then hunt the usual suspects. Caching must be on (Advanced Parameters, Performance), product images served as WebP and resized (not the photographer's 4,000-pixel original), unused modules uninstalled rather than merely disabled, and the theme interrogated about what it actually loads. Thresholds and the detailed method live in our technical SEO audit checklist.
Step 7: product markup and reviews
Product structured data is what puts price, availability and review stars straight into Google's results. On a transactional query, a result showing price and stars crushes the CTR of a bare one.
The audit runs your product pages through Google's rich results test and verifies that every product declares price, currency, availability and reviews when they exist, that the values match what the page displays (a wrong price in the markup invites a manual action), and that the reviews come from real customers through your review module.
Running the audit without losing a week
Done by hand, these 7 areas require a full crawl, Search Console exports and a fair amount of spreadsheet cross-referencing. It is doable, and if you only ever have to do it once, do it.
The alternative: run an automated audit that crawls your store the way Googlebot does and surfaces indexed facets, duplicates, 404s, slow pages and broken markup in a single pass. That is what Bloomwise does, delivering a list of fixes ranked by impact rather than a 200-page report. Start with a free SEO audit to take the store's temperature, and save your energy for the fixes. That is where the traffic gets won.
The bottom line
A PrestaShop SEO audit comes down to 7 work areas: URL configuration, facets under control, stockouts handled with 301s, unique descriptions, categories turned into real landing pages, speed kept in check and complete product markup. The two biggest deposits are almost always the same: facets flooding the index and duplicated manufacturer descriptions. Fix those two and you are halfway there, whether you do it manually or let Bloomwise crawl the store for you.
