All of our Prestashop modules are designed to display quickly but also to be optimized for SEO when possible. For example, take this text, on a native Prestashop you can't insert text after the product list of a category. It is however a very important technique to improve the natural referencing because the links towards the products are in the middle of the content of the page, and not at the end, it increases their quality.
Be aware that most of our modules are installed on this store: the shopping cart, the HTML cache, the compression of images to WEBP format, the RGPD module, etc. Being a user of our modules allows us to better know your needs and to correct bugs faster if there are any.
Finally if you need a particular feature on one of our Prestashop modules do not hesitate to let us know. If it's a feature that can improve the module and serve other users we will gladly do it!
