With Ryte we test your defined homepage at Yoast for indexability. For example, if the indexable version of your page has a slash, but the selected page in Yoast has no slash, the version you’ve set up is not indexable.
Ryte will show this as well. In order to solve this you can adjust the defined homepage at Yoast directly. This usually also affects the indexability status that the Ryte interface shows you in Yoast.
