So Im back with the topic of indexing filters. I've decided now the number of them is too huge and I want to make them noindex. follow.
However, there are like 10 - 15 filters I really, really want to be indexed as they produce good organic traffic. Is there a way to manually change only certain filters to "index,follow"
And other question about canonicals - categories and products have self-referencing canonical tags. Sometimes I want to change it, do any of the SEO plugins offered in the marketplace enable overriding this setting of self-canonicals?
