love when a team's data suddenly looks like a horror movie after a core update. Seen the exact same pattern with our rank trackers over the last ten days - they'll show a sharp dip in visibility, then a manual check reveals we're still sitting exactly where we were before.
What I've realised is Google's getting way better at sniffing out bots and serving hyper-personalised results, especially since that last weekend update. So a lot of tools end up scraping slightly different SERP variants or getting throttled, which produces those phantom "drops" that don't match any real movement.
Are you tracking local packs here, or organic desktop results? The location layer can make things ten times noisier. Honestly, the underlying volatility is still real - it's just not showing itself as cleanly as the tools suggest. The important part is we keep trusting the manual spot checks and use the trackers as a directional signal, not gospel.
