You are taking over a PrestaShop store, sales are dropping for no clear reason, every update is a worry, or you are preparing a migration to PrestaShop 9. Before spending money on fixes, you need to know where the real problems are. The PrestaShop audit gives you that overview, carried out by the team that writes and maintains nearly 300 PrestaShop modules: we know what a well-built module looks like, and what breaks in production.

## What we analyse

### Modules, overrides and code

A full inventory of installed modules, active or not: version, maintenance by the vendor, overrides of core classes, hook conflicts, scripts loaded on every page. We read the code of the modules and of the custom theme, where most bugs and slowdowns hide.

### Security

PrestaShop and PHP versions, known vulnerabilities in installed modules, exposed sensitive files, admin accounts, backups.

### Performance

Core Web Vitals measured on the pages that sell (home, category, product page, cart), the slowest SQL queries, cache configuration, size of the statistics and connection tables. See our article [why your PrestaShop database weighs 8 GB](https://www.datafirefly.com/en/2026/06/14/prestashop-database-ballast-tables-cleanup-retention-2026/).

### Technical SEO

Indexing, canonical tags, hreflang on multilingual stores, URLs generated by faceted filters, redirects, 404 errors, structured data. On these topics, see our articles on the [PrestaShop canonical tag](https://www.datafirefly.com/en/2026/09/21/canonical-tag-prestashop-problem-cases/), [filters and crawl budget](https://www.datafirefly.com/en/2026/09/25/googlebot-crawl-waste-prestashop-filters/) and [404 error audits](https://www.datafirefly.com/en/2026/09/19/404-audit-prestashop-priorities/).

## What you receive

- **A structured report** by area, with the severity of each finding and the supporting evidence: code excerpts, measurements, screenshots.
- **A prioritised action plan**, from urgent fixes to deeper improvements, costed in days and euros.
- **A one-hour debrief** to answer your questions and set priorities together.

You are free to carry out the fixes with your team, another provider or us. The report does not change based on your choice.

## What affects the price

The audit starts at €1,800, with a fixed quote:

| Factor | Impact |
| --- | --- |
| Number of modules | Every third-party or custom module is inventoried and read. |
| Custom theme | A heavily customised theme takes longer to review. |
| Multistore and languages | Each store and each language adds SEO and functional checks. |
| Volume | A large catalogue or a heavy database requires more performance analysis. |

## The tools we publish to fix issues

Several common problems found during audits led to modules in our catalogue:

- [PrestaShop database cleanup](https://www.datafirefly.com/en/product/dfcleanup-prestashop-database-cleaner/): statistics tables, obsolete carts and connections.
- [301 redirect manager](https://www.datafirefly.com/en/product/301-redirects-manager-prestashop/) with 404 error tracking.
- [Hreflang tags](https://www.datafirefly.com/en/product/prestashop-8-hreflang-module-multilingual-seo-alternate-tags-datafirefly/) for multilingual stores.
- [Core Web Vitals](https://www.datafirefly.com/en/product/dfcoreweb-core-web-vitals-prestashop/): lazy loading, critical CSS and image optimisation.
- [SEO facets](https://www.datafirefly.com/en/product/faceted-seo-engine-prestashop/): filter URLs indexed or excluded according to your rules.

## What merchants say

Merchants who put their store back in order with our modules:

- “after importing from woocommerce and after three years of work i had a lot of duplicate attributes, especially sizes, making the related filter almost useless. now instead everything is much more organized.” _Giuliano Stella (clickintimo.it), duplicate attribute merge module (review translated from Italian)_
- “The module works perfectly and the support is very fast. Highly recommended.” _Massimiliano Baldizzone, PrestaShop Hreflang module_
- “Matches the description and works really well.” _Serge, LD Medical (ld-medical.fr), PrestaShop Cookie Manager module (review translated from French)_

To date, every review published on our product pages is rated 5 out of 5.
