Should you let search engines index blog category & tag pages?
Categories or tags still tie important keywords to your blogs by simply having them on-page.
However, when taken seriously by providing unique value, these pages may become pillars meaning they can rank for vital keywords.
This setup is perfect for topics that matter yet aren’t essential to your core offering, as they already have the main quality of a pillar page: internal links from similar & long-tailed subjects.
You can add category or tag-based feeds to your Solutions pages too. This keeps them fresh, often boosting keyword rankings, while sharing relevant thought leadership for your users.
