We have an automobile website with pages in following hierarchy: Home > Make > Model > Variant i.e. Home > Audi > A4 > TFS1 Premium Plus
We are showing the breadcrumbs on our desktop page but not showing them on mobile websites due to space constraints. Is there any SEO wise potential downside by not showing the breadcrumbs?
It would be great if someone can share any official google document or relevant case study for this.
