Honestly, yeah, that’s the annoying part — when GSC is swinging around like that, it’s hard to tell if you’ve got a real issue or just Google doing its usual nonsense. I’d still be checking crawl stats and server logs before touching anything. If the bot’s still hitting the pages normally and you’re not seeing weird 5xx/4xx stuff, I’d be a lot less convinced it’s a plugin/hosting problem. If crawl rate dropped hard or certain URLs just stopped getting fetched, then yeah, that’s where I’d start digging. Also, “same plugins” doesn’t always mean same output. I’ve had a cache plugin update change headers enough to mess with indexing without anything obvious breaking. Super irritating because everything looks fine until you compare before/after responses. If it’s only been a few days, I’d typically watch it a bit more before ripping stuff apart. If it keeps sliding for another week or two, then I’d start checking canonicals, rendering, and whether any pages lost internal links.
