Meta & Head
19.4/25
Title, description, canonical, social tags — what search engines read first.
Meta descriptionhigh impactlow effort
No meta description found
The meta description is your ad copy in search results; without one, engines pull an arbitrary snippet from the page, which usually reads poorly and costs you clicks. Add <meta name="description" content="..."> with 70–160 characters that summarize the page and give a concrete reason to click — what the visitor gets plus a differentiator (free, instant, no signup). Write a unique description per page: one duplicated across the site is treated much like a missing one.
Open Graph tagsmedium impactlow effort
Missing Open Graph tags: og:description, og:image
Your Open Graph markup is incomplete, so social platforms fall back to guessed text or drop the preview image entirely when this page is shared — a broken card gets far fewer clicks than a complete one. Add the missing og:description, og:image tags to <head>. For og:image, use an absolute https:// URL to an image around 1200x630 pixels; relative paths are the usual reason previews break. Re-check with a platform's sharing debugger afterwards, since preview cards are cached.

HTTPS, redirects, robots, sitemap, speed, crawlability.
Short redirect chainmedium impactlow effort
https://maxzuercher.ch/ (301) → https://www.maxzuercher.ch/
Every redirect hop adds a round-trip before the visitor sees anything, each hop can leak a little link equity, and crawlers abandon long chains — which can leave the destination page undiscovered. Trace the chain above and point the first URL directly at the final destination in a single 301; commonly this means merging separate http-to-https and non-www-to-www rules into one combined redirect. Also update internal links to reference the final URL directly, so most visitors never enter the chain at all.
Response compression enabledlow impactlow effort
no content-encoding header
This HTML is served uncompressed, so every visitor downloads far more bytes than necessary — text compresses extremely well, and the savings directly speed up first render on slow connections. Enable Brotli or gzip on your server or CDN: in nginx it's "gzip on;" (or the brotli module), in Apache it's mod_deflate via .htaccess, and on most CDNs it's a single toggle. Make sure compression covers all text types (HTML, CSS, JS, JSON, SVG), but skip already-compressed images — recompressing them wastes CPU for no gain.
Reasonable HTML sizelow impactmedium effort
1.6 MB
A very large HTML document slows parsing on every visit and risks exceeding the portion of a file crawlers are willing to fetch — content past the cutoff may simply never be indexed. Slim it down: move large inline <script> and <style> blocks into external cacheable files, strip embedded JSON data blobs and base64-encoded images, and paginate or lazy-load very long listings. Check the most common culprit first: a framework serializing the entire page state or dataset into the document itself.
