I’d check whether the important pages are still indexed, look for duplicate or thin content, and make sure the content is actually matching search intent.
If those pages start gaining traction again, that gives you a useful signal about what’s working before you invest time into updating or publishing more content.
That’s how I’d approach it too. If several sites dropped at the same time, I’d first check Search Console for manual actions, indexing issues, and exactly which pages or queries lost visibility rather than immediately publishing more content.
I’d first check Search Console to see exactly where the drop happened. If multiple sites lost traffic around the same time, I’d investigate whether there was a broader update or quality-related change rather than simply publishing more articles.
Once those pages stabilize, you’ll have a better idea of what Google is responding to and can build new content around that instead of adding volume blindly.
