Priority fixes for halifax.co.uk
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.
95% of Banking & Finance peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Enable
robots.txt published
Observed: No robots.txt file was returned at the site root.
What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.
86% of Banking & Finance peers do this.

Priority 3 · Enable
XML sitemap discoverable

What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
76% of Banking & Finance peers do this.

Priority 4 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 0 seconds, short of the 30-day benchmark.

43% of Banking & Finance peers do this.
