Good comment! I’d add in one more question so we can put the GA tag issue to rest.
Does the writer have access to Google Search Central? They rename this product every six minutes. It used to be Google Webmaster Tools and it’s likely called something new now. Are there any manual actions or security alerts in there??
If Google performs a manual action or picks up certain types of security problems, they will tank traffic. But they usually report to give webmasters the chance to fix it.
I’d avoid ahrefs and the like and start right with google tools.
