Prestashop has a few built-in options for SEO, the title, meta description and the meta keywords can be modified from the admin panel.
Follow these steps to see how to modify the meta values or add new ones: login into admin panel, go to “catalog”, you should see there all the available categories, click the “edit” icon for any category. There should be three options: “Meta title”, the title of the category. By default, Prestashop will just use the name of the category like “Dresses” for example if the category is named Dresses.
“Meta description”, this one should explain what the page is about within a few words. And the last option: “Meta keywords”, don’t bother with this one as meta keywords are now useless.
To modify the meta title and the meta description for a specific product, go to “Catalog”, click on the “edit” icon for any product. It will now display the full interface for that product.
There is a link inside there that can expand the SEO tools called “Click here to improve product’s rank in search engines (SEO)”. By clicking on that link, you should have access to the meta title, meta description, keywords and the friendly URL value.
