Some CMS and hosting providers already include analytics, so an additional script isn’t required. Turn off any other third-party scripts when they’re not actively being used or reviewed, a heat-mapping tool like Hotjar left running long after the insight was gathered is dead weight on every page load.
This is really a specific case of a broader rule: limit the number of third-party scripts on a page to the ones actually earning their keep. Where a third-party analytics tool is genuinely needed, consider a lighter-weight alternative to GA4.
