Why it matters
Passing Core Web Vitals and SEO checks gets harder when you are shipping features
Product updates can slow pages and hurt crawlability. RebelBoost prevents regressions so performance gains stick with every release.
Performance and UX stakes
- Slow LCP, INP, and TTFB reduce engagement, revenue, and rankings.
- Core Web Vitals shift as new components and experiments ship.
- Edge caching misses long-tail templates and device variants.
Why teams struggle mid-release
- Multiple H1s, missing viewport tags, and nofollowed internal links slip in.
- Redirect chains and missing canonicals quietly erode authority.
- Rebuilding CSS, JS, and images slows delivery without fixing everything.
