Akurai theme comes with built-in breadcrumbs since version 1.0.9.
To add a breadcrumbs to your website you need to enable them. In your WordPress dashboard visit Appearance → Customizer → Breadcrumbs Options to enable breadcrumbs as well as adjust settings.
Reviews page Parent page
Akurai doesn't enforce users to have a parent page for review pages, however you can set one in breadcrumbs.
By default breadcrumbs for posts pages includes categories, however you can add blog page as well. Just make sure to check the box Include blog page in posts breadcrumbs.
Akurai also includes structured data markup for breadcrumbs out of the box, so you don't need to do anything.
Do not enable breadcrumbs option in Yoast, as you'll end up having duplicate markup.
