Priority fixes for craigslist.org
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.
94% of E-Commerce & Marketplaces peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
93% of E-Commerce & Marketplaces peers do this.
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.
44% of E-Commerce & Marketplaces peers do this.
Guide: Control Third-Party Scripts Before They Control Your Page
Priority 4 · Enable
At most one redirect to the homepage
Observed: The homepage was reached after 2 redirects.
What to do: Point every alternate address (http, www or apex, old paths) straight to the final URL in a single redirect.
98% of E-Commerce & Marketplaces peers do this.
