The Adsvise Difference

Why standard speed tests leave money on the table

Lighthouse gives you technical scores. Adsvise calculates the exact financial damage and provides the roadmap to fix it.

Calculates the "Hidden Tax"

For every 1 second of mobile delay, conversion rates drop by roughly 7%. We map your millisecond lag into concrete revenue loss so stakeholders finally take action.

Connects speed directly to gross merchandise value.

Isolates 3rd-Party Scripts

Meta Pixel, Google Tag Manager, Klaviyo, and TikTok tags freeze the browser thread. We dissect each external script to show who is stealing your load time.

Pinpoints exact CPU time wasted per marketing vendor.

Simulate Offloader Gains

See what happens if you run heavy scripts off the main thread with our interactive simulator. Keep 100% of your tracking data with 0% of the customer friction.

Simulate your jump from score 50 to 90+ before committing.

Frequently Asked Questions

Got questions? We’ve got answers.

Is the Adsvise homepage behind a login wall, or can I view everything freely?
The Adsvise homepage and all core speed diagnostics are 100% public with no login wall. Anyone can inspect website speed, calculate script bloat revenue impact, and view full optimization roadmaps without signing in or creating an account. Logging in via Google is strictly optional for users wishing to save ongoing historical domain scans and configure recurring alerts.
No. Our speed test runs 100% externally via Cloudflare Workers and Google PageSpeed Insights API. You do not need to give us access, install any plugins, or touch your codebase to see your initial audit.
The calculation utilizes industry-standard e-commerce benchmarks (Deloitte Digital & Google research) which show that every 100ms of mobile delay reduces conversion rates by 0.7% to 1.1%. We correlate your third-party script execution time against your monthly traffic and order volume.
Marketing scripts (Facebook Pixel, TikTok, Pinterest, Hotjar, Google Tag Manager) are downloaded from external servers and execute unoptimized JavaScript on the single main browser thread. This blocks user taps, input responsiveness, and delays Largest Contentful Paint (LCP).
Absolutely! You can paste any publicly accessible URL to analyze competitor speed, assess agency prospects, or audit client stores before presenting performance optimization proposals.
