I notice in Analytics that my posts have lots of letters and numbers after them, for example myposttitle.com?7f478gf4uvhuvjkdfb98r8hhv9hverovhr08h397gfgd + some the same in google search console. I have no idea what this means but doesn't look good to me. Can anyone explain what is happening?
These values appear due to the data that is passed through. For example, make a route from place A to B to C in Google map. Copy this URL in the browser and paste it in other browser, you will get the same map and the URL will contain the letters/numbers and symbols.
