Priority fixes for gameduell.de

Ordered by impact and by how common each practice is among peers.

  1. Priority 1 · Accelerate

    HTML compressed

    Observed: The homepage HTML (52 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.

    93% of Puzzles & Video Games peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

  2. Priority 2 · Enable

    Mobile viewport configured

    Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.

    What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.

    91% of Puzzles & Video Games peers do this.

  3. Priority 3 · Accelerate

    Static files cached for 30 days or more

    Observed: A same-site stylesheet or script was cacheable for no max-age, 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.

    44% of Puzzles & Video Games peers do this.

  4. 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.

    60% of Puzzles & Video Games peers do this.
