Priority fixes for pythonanywhere.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected http/1.1 instead of HTTP/2.
Why it matters: HTTP/2 sends many files over one connection, which speeds up pages with lots of images, styles and scripts.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
83% of Web & Cloud Hosting peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 10 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
47% of Web & Cloud Hosting peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 1 external script without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
61% of Web & Cloud Hosting peers do this.
Guide: Control Third-Party Scripts Before They Control Your Page
Priority 4 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
70% of Web & Cloud Hosting peers do this.
