Can you recommend an SEO app for editing product variant URLs?

Hey!

As straight forward as it gets. Looking for an app to edit variant specific URLs on my site (   i.e.      https:// [[{store name}]] .com/products/ [[[sweatshirt-name]]] -large   )

Hoping to be able to differentiate my products, plus be able to push on Google and other search engines.

Thanks,

Santo
