“indexable only” option on tier filter β€” πŸ‘‰ GSA SEO and Marketing Forum πŸ‘ˆ

on the “tier filter” under “data”

project>data>tier filter>3rd tick box “indexable only”

how does it define “indexable” because one of the purposes is to build lower tiers to index the urls above, so if it is’nt indexed now, should’nt you be building links to it ?

please explain what this means because surely all of the links above are potentially “indexable” if you build links to themΒ  below ?
