I am wanting to integrate breadcrumbs into a client site. The client is fine with this but wants them at the bottom of the page. Does this have any negative effects on breadcrumbs contribution to SEO improvements?
Google directly displays breadcrumbs under site links via structured data. I know Google can pick and decide what structured data it will actually display despite the information you provided. So I am wondering if they are too low on the page if they have a less likelihood of showing up under some links. I don't know if breadcrumbs are treated like other structured data in this regard and what effects them.
