SYMPTOMS

The symptoms of a web platform holding back growth

Long uploading time

Excessive load times

Every second of load time costs conversions. Beyond 3 seconds, more than half your visitors leave.

Core Web Vitals in the red

LCP, FID, CLS. Google measures your site's performance and penalizes your ranking when scores are poor.

silent errors icon

Client-side rendering only

SPAs without SSR are invisible to Google and slow for users. First paint takes seconds instead of milliseconds.

manual reports icon

Unoptimized assets

Uncompressed images, unminified CSS and JavaScript, fonts loaded in bulk. Quick wins that nobody took the time to implement.

inventory mismatch icon

Undersized infrastructure

Shared hosting, no CDN, no cache. Your platform isn't configured to handle your current traffic.

fragmented decisions icon

No measurement in place

No monitoring, no baseline, no alerts. You don't know your site is slow until a customer complains.
