Some personalizations replace your existing HTML elements, however, our tracker can only make your existing element invisible once the tracker is loaded. Then we immediately replace your personalization, this can cause a flicker effect.
Therefore we have a very light script, which hides all potentially hideable elements as fast as possible, actually already when loading the page. You need to load this separately, at the top of your head tag for all other scripts (this also works if you do load the tracker via GTM).
Replace your personal merchant ID at the m parameter:
<script async type="text/javascript" src="https://squeezely.tech/p?hqs=1&m=SQ-ID"></script>
Note: Does the visitor not qualify for the personalization and needs to show the original element again? Then we display the hidden element again trying to avoid a flicker effect.
