Third-party cookies
Google Analytics (_ga, _ga_*) measures visits. Google AdSense and DoubleClick cookies measure and personalise ads. These scripts load after the page settles and never while a speed test is running.
You can block third-party cookies in your browser, or opt out of personalised ads at Google Ad Settings. The speed test and tools work the same either way.
