Page flickers

When conducting an Optimize test via Site Kit, users may see a page flicker where the page first displays original text, then quickly changes to the alternative text set for the Optimize experiment. 

To ensure that this flicker does not occur, go to Site Kit > Settings > Connected Services > Optimize and turn on the toggle for Place anti-flicker snippet on your site, then click Confirm Changes.
