From what I understand, the closer a page is to the root the better it is for SEO. So something like http://mystore.com/book1 has more SEO authority over http://mystore.com/cat1/author1/book1 given that there’s no requirement to keep cat1 in the url.
If I were to flatten my store’s URL to http://mystore.com/book1, should I also reflect this in the breadcrumb so that it no longer follows cat1 > author1 > book1?
Note that I want to keep the page http://mystore.com/cat1 and even http://mystore.com/cat1/author1 (or an alternative http://mystore.com/author1).
Thanks
For seo it’s better flatten urls such as http://mystore.com/book1, and there is no problems with breadcrumbs that follows cat1 > author1 > book1 (search engines not so smart to determine breadcrumbs on site), but if breadcrumbs are links so for seo would be better cat1 > author1 > book1 then just one link book1.
PS: I think that breadcrumbs are for real people more needed then for seo 🙂
