When I looked at my Google Search Console today, it seemed like my traffic had dropped to zero! I watch my traffic closely as I am trying to learn what influences visibility in Google. I recently found out that Site Vitality seems to have a big impact on your visibility. But in order to be able to see your site vitality you have to be in the CrUX report. And in order to get there you have to have a minimum amount of traffic (I assume).
