Frequently asked questions
What is the tools page meant to rank for?
The tools page is best positioned as a utilities hub. It helps users discover helpful free tools instead of competing directly with the dedicated single-purpose pages.
Should each tab have its own page?
For now the tools hub works as a discovery page, while the metadata and content focus on the broader tools intent rather than over-optimizing one tab.
How does this help the rest of the site?
A strong tools hub improves internal linking and gives users clear next steps into the more focused landing pages.
