SEO at MonSiteBug in numbers

SEO is a cross-cutting topic that affects all CMS platforms. Here's the breakdown of our 206 SEO tickets by platform:

Observation: PrestaShop clearly dominates our SEO interventions with 69 identified tickets. This is no coincidence: PrestaShop has historical SEO weaknesses (duplicate content, complex URLs, faceted navigation) that require deep technical expertise to fix.

Most common PrestaShop SEO problems

Across our 69 PrestaShop SEO tickets, we consistently encounter the same issues. Here are the root causes we most frequently fix on PrestaShop stores:

1. Duplicate content and canonical URLs

Duplicate content is PrestaShop's #1 SEO problem. By default, PrestaShop can generate multiple URLs for the same product:

• /category1/my-product and /category2/my-product (same product in two categories)
• Sort and filter parameters creating unique URLs (?order=price&resultsPerPage=20)
• Pagination pages (/category?page=2) without canonical tags
• HTTP and HTTPS versions not unified

The solution: properly configure canonical tags, set up indexing rules in the robots.txt file, and enable friendly URLs in PrestaShop. For complex cases, we intervene directly in template files to force the correct canonical.

2. Sitemap issues

The XML sitemap is essential for Google to discover and index your pages. On PrestaShop, the sitemap issues we handle:

• Sitemap not generated or empty file — often due to a module conflict
• Oversized sitemap (>50,000 URLs) without splitting
• 404 URLs in the sitemap — deleted products still listed
• Sitemap not declared in Search Console — basic but frequent error
• Sitemap module incompatible with the PrestaShop version

3. Google Search Console errors

Google Search Console is the essential tool for monitoring indexation. The errors we fix most often:

• "Page with redirect" — redirect chains 301 → 301 → 301
• "Discovered – currently not indexed" — filter pages polluting the index
• "Server error (5xx)" — related to our 747 error 500 cases
• "Duplicate page without canonical URL" — the duplicate content problem
• "Blocked by robots.txt" — overly restrictive configuration

4. Faceted navigation and SEO

Faceted navigation (filters by price, color, size...) is an SEO trap on PrestaShop. Each filter combination creates a unique URL, potentially generating thousands of near-duplicate pages. Our approach:

• Adding noindex, follow on filtered pages
• Configuring robots.txt to block filter parameters
• Using canonical tags pointing to the main category
• Setting up URL parameters in Google Search Console

5. 301 redirects and URL migration

During a PrestaShop update or URL structure change, 301 redirects are crucial. Common errors:

• No 301 redirect after a product slug change
• Redirect chains (old URL → intermediate → new URL)
• Redirect loops (URL A → URL B → URL A)
• SEO juice loss after migrating from PrestaShop 1.6 to 1.7/8

This topic directly relates to our PrestaShop update interventions, where redirects are a critical step in the migration process.

Structured data (Schema.org) and rich snippets

Structured data enables Google to display rich snippets (stars, price, availability) in search results. On PrestaShop, the issues we fix:

• Missing or incomplete product Schema.org — Google can't display rich snippets
• Structured data errors in Search Console — missing required fields
• Organization Schema.org misconfigured for the Knowledge Panel
• Breadcrumbs not marked up with Schema.org
• FAQ Schema not implemented on category/CMS pages

Properly implemented structured data increases click-through rate (CTR) by 20-30% on average in Google results.

Performance and SEO: the Core Web Vitals impact

Since 2021, Google uses Core Web Vitals as a ranking factor. Performance directly impacts SEO, which is why our 278 performance tickets are inseparable from search optimization.

The three Core Web Vitals metrics we optimize:

• LCP (Largest Contentful Paint) — loading time of the main element. On PrestaShop, often degraded by unoptimized images and heavy themes
• INP (Interaction to Next Paint) — page responsiveness. Heavy JavaScript modules degrade this metric
• CLS (Cumulative Layout Shift) — visual stability. Ads and PrestaShop sliders are often responsible

Our Web Vitals improvement service combines technical optimization with SEO gains. Every millisecond saved on loading time has a measurable impact on Google ranking.

Mobile-first indexing: a critical challenge

Since 2021, Google exclusively uses the mobile version for indexing. On PrestaShop, the mobile indexing issues we fix:

• Non-responsive theme — content hidden on mobile not indexed
• Different mobile/desktop content — Google sees the mobile version, not the desktop
• Insufficient mobile speed — loading time exceeding 3 seconds
• Interactive elements too close together — penalization in the Mobile Usability report
• Viewport not configured — rare but still present on PrestaShop 1.6 sites

PrestaShop URL structure and site architecture

URL structure is fundamental for SEO. On PrestaShop, the best practices we implement:

• Enabling "friendly URLs" in PrestaShop (Shop Parameters → Traffic & SEO)
• Removing numeric IDs from URLs (/12-my-product → /my-product)
• Relevant keywords in URLs for products and categories
• Consistent hierarchical structure: category → subcategory → product
• Language management with proper hreflang and URL structure (/fr/, /en/)

Meta tags and SEO content

Meta tags (title, description) remain an SEO cornerstone. The errors we frequently fix on PrestaShop:

• Identical meta title across all pages — often the default store name
• Empty or auto-generated meta description — PrestaShop truncates product text without optimization
• Missing or duplicate H1 tag — common issue with PrestaShop themes
• Images without alt attribute — important for image SEO and accessibility
• Product content too short — 2-3 line descriptions insufficient for ranking
