Priority fixes for ilmatieteenlaitos.fi

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

1. Priority 1 · Enable

   Canonical URL declared

   Observed: The homepage did not declare a canonical URL.

   Why it matters: A canonical link tells search engines which URL to show when the same page is reachable at several addresses.

   What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.

   61% of Weather Forecast peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

2. Priority 2 · Accelerate

   Modern image formats in use

   Observed: The homepage had 11 images and none used WebP or AVIF.

   What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.

   On Nuxt: Nuxt Image can output WebP and AVIF.

   23% of Weather Forecast peers do this.

3. Priority 3 · Accelerate

   Offscreen images lazy-loaded

   Observed: The homepage had 11 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.

   50% of Weather Forecast peers do this.

4. Priority 4 · Harden

   Framing restricted

   Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.

   What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.

   On Amazon CloudFront: Set frame options in a response headers policy.

   38% of Weather Forecast peers do this.
