Priority fixes for onshape.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (201 KB) was delivered without gzip, Brotli or zstd compression.
Why it matters: Compression usually shrinks HTML several times over, so the first bytes of the page arrive sooner on slow connections.
What to do: Enable Brotli or gzip for text responses (HTML, CSS, JavaScript, JSON, SVG) at the CDN or origin.
94% of Programming & Software peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 4 external scripts 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.
51% of Programming & Software peers do this.

Priority 3 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 6 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
56% of Programming & Software peers do this.
Priority 4 · Enable
Page language declared
Observed: The homepage <html> element had no lang attribute.
What to do: Set lang on the html element (for example lang="en") and on any sections in another language.
90% of Programming & Software peers do this.
