From the SEO technical point of view, can the use of Multiple Breadcrumblist (https://developers.google.com/search/docs/appearance/structured-data/breadcrumb#html_example) be a negative signal for the search engine in understanding the relationship and structure of the site pages?
From a UX point of view, it may not have a good effect, because the user may go through a different path to reach a resource, but the breadcrumbs displayed on the screen may be something else.
In large sites, it often happens that a resource is available from different categories.
Although when we use multiple breadcrumblist, we will still have one url for a specific resource
Do you have any experience in this field?
Hi @Amir Hosseinpour,
Excellent question.
I don't see a problem with using multiple breadcrumbs. The big question will be: how prominently the information will be made available to users so that they understand the taxonomies.
As for search engines, I see that there will be no problems as long as the information architecture is planned appropriately.
Famous news portals like The New York Times work with this very well.
In my experience, having multiple breadcrumbs doesn't hurt a site's search results but it doesn't benefit them either. Even though it is technically OK to define multiple breadcrumbs the search result snippets will only show 1, so there's no added benefit regarding rich results.
