there has to be a balance between evergreen and news. also, interlinking is a major win. you have to have good category pages, category descriptions with contextual links, and news that link to evergreen and categories WITHIN the text, not programmatic interlinking blocks. If you do it manually - that's one FTE doing just that. Or... use AI. This is the best s*tty job for this.
News traffic - depends on what you mean here. The news tab is dead meat. nobody's using it. The biggest hit is the top stories snippet, but to get there you have to work your *** off for 2 years at least... Google takes 13 months of historical data, if you've not been publishing news consistently during this time - at least 5 items per day with good behavioral signals and traffic - you're out.
