When to choose Google Ads

Google Ads doesn't clearly lead HTTP/3 in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.

When to choose HTTP/3

Choose HTTP/3 when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.

How this comparison was built

Scores are medians across 100 audited Google Ads sites and 2143 audited HTTP/3 sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.
