1 – Navigation menu in the header (on the top) loads 3 times.
2 – Navigation Menu in the SideBar (on the left) is load 2 times : 1 before the content, another after content. Make Ctrl+F with following terms to see : Catégories, Prix, Spécificité, Hauteur, Largeur, Délai d’expédition.
For those issues, we know that when one menu is displayed, others are hidden. However Google Sees all of them and our SEO Manager says that a website must have to only ONE MENU in the header and one in the sidebar, no duplicate.
So we informe you hoping you rewrite those both menu.
