What IS SEO FRIENDLY BEST PRACTICE FOR URLS FILTERED 'TAGGED'

[Sscha003]

EX: https://www.STORENAME.com/collections/all-deals/alcatel– Tagged "Alcatel", when I run audits, I come across these URLS that give me duplicate content and missing H1.  This is Canonical:

https://www.STORENAMEcom/collections/all-deals/alcatel

Any advice on how to tackle these I have about4k in my store! Thank you
