I'm having a new ecomm store built (PrestaShop) and we currently use a URL suffix like: '...product-name.html#/141-colour-423881earthy_colours005ivory' to control the default product colour. The whole URL including this suffix is quite long, even rewriting without the category and database codes its about 120 chrs. Is this '#/...' suffix likely bad for SEO or will it be ignored by Google?
Generally when I see a pound sign within a url, it's typically either someone deadening a link like at the top of a dropdown on a navbar or an actual url that uses mouse scroll event utlizing sections with html tags. With java you can use the mouse scroll event and have users click a link that is actually within the same page, but a distance down the content. But I don't typically see it just arbitrarily for no reason.
