SEO optimization and finalization of a WordPress / Beaver Builder site

Hello, I am looking for a person to take charge of the optimization and finalization of a WORDPRESS site developed with the page builder BEAVER BUILDER. It is an e-commerce site with a small catalog (50 products). A good part of the work has already been carried out and it is essentially a question of optimizing the existing one. > 5 pages (Home - Collection - Typical product page - Typical quotation pages - Contact - Order process ) // The graphic design is already done > Woo commerce store interface // The interface is already done but there is still some work to do. > Integration of a payment solution (Paypal or stripe) > Multilingual site (French, English, Spanish) // The multilingual interface is already done The work to be done is as follows: - Finalization of some small details related to the graphic design (logo spacing, hero zone too much stuck to the menu ... only small details) - Optimization of the created pages >> The goal is to finish the 4 typical pages first so that I can translate them and quickly start the creation of the product catalog. - Optimization of the mobile version (use of conditional instructions (mobile, desktop) ...). The site must be 100% mobile compatible. - Installation of a plugin to sort the media and pages by folders. - Installation of Facebook Pixel, Google Tag Manager and the necessary marketing and SEO tools. Optimization of the Search console configuration. - Putting the site on the right URL (the old version is currently on it) - Hosting optimization (02switch) and installation of the Cloudflare CDN . <<IMPORTANT> : >> Use all SEO best practices: optimization of the site resource management (minification, css concatenation, combination of CSS / JS files (defer or async attributes to .js files), CSS background image and background position, below waterline scripts, http request reduction, browser caching, image compression and file optimization (normally, it's already done), transformation of images into CSV if needed...) >> The pages of the site must be very light with a very good loading time. This is one of the first objectives of this redesign project, so it's very important. Waiting for your feedback, Have a nice day! Nicolas
