Prestashop

How it works

PrestaShop is a self-hosted ecommerce platform that runs on a PHP and MySQL stack with Symfony dependencies. When a visitor requests a page, the server processes PHP code, queries the MySQL database for product, category, and customer data, and renders HTML templates. The platform generates URLs, metadata, and internal links dynamically based on its configuration and installed modules.

For SEO, PrestaShop exposes many controllable technical layers. Store owners can edit URL structures, meta titles and descriptions, heading tags, image alt text, and internal linking patterns through the back office or by modifying theme templates. The platform also supports canonical tags, robots.txt, and sitemap generation, though these features may require module installation or customisation. Because it is self-hosted, owners have full control over server settings, caching, and performance tuning, which directly affect crawl efficiency and user experience.

PrestaShop's modular architecture means that themes and third-party modules can alter how pages are rendered and indexed. A poorly coded theme might inject duplicate content or block search engines, while a well-optimised one can improve page speed and structured data. Regular audits of themes, modules, and crawl rules are necessary to maintain SEO health, as core updates and module changes can introduce new issues.

Where it changes your decision

• When choosing an ecommerce platform for a store that requires full control over code, data, and configuration, PrestaShop is a strong option because it is self-hosted and open-source, unlike SaaS platforms that limit customisation.
• When planning an ecommerce seo strategy, PrestaShop's exposure of technical layers such as URLs, metadata, and internal linking means that SEO practitioners can directly optimise crawlability and indexation, but they must also manage duplicate content from faceted navigation and filters.
• When evaluating hosting and performance, PrestaShop's self-hosted nature means that server setup, caching, and SSL configuration are the owner's responsibility, and poor performance can harm crawl efficiency and rankings.

What it is not

• PrestaShop is not a hosted SaaS platform like Shopify; it requires separate hosting, domain, and SSL, and the owner handles updates, backups, and security.
• PrestaShop is not a general-purpose website builder; it is designed specifically for ecommerce and lacks features for blogs, portfolios, or corporate sites without extensive customisation.
• PrestaShop is not a 'set and forget' SEO solution; its SEO performance depends on theme quality, module configuration, and ongoing audits, not just the core software.
• PrestaShop is not immune to duplicate content issues; faceted navigation, filter URLs, and multiple product variations can create duplicate pages that require canonical tags or noindex rules.

Common mistakes

• Treating PrestaShop as 'set and forget' SEO instead of auditing themes, modules, and crawl rules after install. Consequence: undetected issues like broken metadata, slow pages, or blocked indexation harm rankings.
• Assuming the core software alone guarantees good rankings without fixing duplicate content, filters, and internal linking. Consequence: search engines may index multiple versions of the same product page, diluting ranking signals.
• Installing too many modules that slow pages or create conflicting metadata and URL patterns. Consequence: page speed drops, crawl budget is wasted, and search engines may see contradictory signals.
• Ignoring hosting, SSL, and performance, even though the platform is self-hosted and these factors affect crawl efficiency and UX. Consequence: slow load times and insecure connections reduce rankings and user trust.
