Frequently Asked Questions

Is Microsoft Clarity really free?

Yes, Microsoft Clarity is 100% free with no premium tiers, traffic limits, or hidden costs. All features including heatmaps, session recordings, and AI insights are available at no charge.

Does Clarity slow down my Shopify store?

Clarity uses an asynchronous tracking script that loads after your page content, so the impact on page speed is minimal and should not noticeably affect your store performance.

Can I use Clarity alongside Google Analytics?

Yes, Clarity integrates directly with Google Analytics, allowing you to combine behavioral data from Clarity with traffic and conversion data from GA for deeper analysis.

Will this app conflict with my theme or other apps?

Booster Page Speed Optimizer is designed to work alongside Shopify themes and other apps. It uses non-destructive optimization techniques, but if conflicts arise, their support team can help resolve them.

How quickly will I see speed improvements?

Most merchants see measurable improvements in page load times and Core Web Vitals scores within minutes of enabling the optimization features.

Does it affect my store appearance or functionality?

No, the app only optimizes how resources are loaded — it does not change any visual elements or functionality of your store. Lazy loading is designed to be invisible to visitors.
