Priority fixes for fast.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Mobile viewport configured
Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.
Why it matters: Without it, phones render the page at desktop width and shrink it, which makes text tiny and hard to use.
What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.
97% of Web Tools peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
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.
92% of Web Tools peers do this.
Priority 3 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 5 days, short of the 30-day benchmark.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
54% of Web Tools peers do this.
Priority 4 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
73% of Web Tools peers do this.
