What impact does the Online Store Speed Report have on small sites?

Thank you, Yeti. Your analysis is spot on. Google Analytics does NOT record these “mystery” Council Bluffs sessions. And since Google Analytics requires the client software initiating store sessions to have JavaScript active, this is a sure sign that this is a robotic process, and not being initiated by a human. It also makes sense that Shopify is performing these speed checks across the scope of the three primary page types, so I have no intention to request that Shopify stop doing them. But since I too am just starting out and will never have a large number of sessions day-to-day anyway, it’s just helpful to know what these Council Bluff sessions are all about to avoid the let down when I see that there were three new sessions overnight that were not prospective customers.
