If a website has inconsistency between URL structure and Breadcrumbs structure is it good, neutral or bad for SEO?

For example on Yoast site "Wordpress Plugins" page https://yoast.com/wordpress/plugins/:

  • Parent page according to URL is https://yoast.com/wordpress/

  • Parent page according to Breadcrumb is https://yoast.com/software/

enter image description here

And same effect but even more inconsistency on the deeper level page https://yoast.com/wordpress/plugins/seo/

enter image description here

The mentioned site belongs to a company that is considered the guru of SEO. This makes me think that inconsistency somehow could give better SEO results? Or at least not negatively affect SEO.

So, is it justifiable from SEO point of view to have inconsistent URL and Breadcrumb structure? It it reasonable? Or does it not affect SEO negatively?

Any ideas?

  • @SimonHayter Clearly, this question is on the fence depending upon how you read it. I read it a an SEO question using Yoast as an example of where the interest comes from. For me, it was interesting from that perspective. You are right to put this on hold for the reason you cited. Cheers!! – closetnoc Jun 19 '16 at 2:35

    Edited the question to be less about 3rd party website. The point of course is not to review a site not under my control. My intent is to ask a SEO question. And I used the site as illustration. Hopefully this will work? – Oleg Jun 20 '16 at 13:30
