Title, description, canonical, social tags — what search engines read first.

Everything we check in this category passed.

Headings, copy depth, images, structured data, internal linking.

• Single H1 headinghigh impactlow effort

  0 h1 headings found

  The h1 is the visible headline of the page and one of the clearest signals to search engines of what it's about; with none present, engines lean on surrounding text and may misread the topic. Add exactly one h1 near the top that states the main topic in plain language and includes the primary keyword, e.g. <h1>Merge PDF Files Online</h1>. Don't fake it with a styled <div> — the semantic tag itself is what crawlers and screen readers actually read.

• Heading hierarchylow impactlow effort

  Heading level jumps from h2 ("Unsere Leistungen") to h4 ("Risikobewertung")

  Headings form the page's outline; when levels jump (h2 straight to h4), search engines and screen readers get a broken table of contents and the relationship between sections turns ambiguous. Fix the jump by stepping down one level at a time — promote the deeper heading, or add the missing intermediate level. The usual cause is choosing heading tags for their default font size; set sizes in CSS instead and let the tags reflect actual document structure.

• Hreflang annotationslow impactlow effort

  1 hreflang link(s) present but no x-default entry

  Your hreflang set has no x-default entry, so search engines must guess which version to show visitors whose language you don't list — and they often pick a poorly matched one. Add <link rel="alternate" hreflang="x-default" href="https://www.example.com/"> pointing at your fallback page, typically the English version or a language-selector page. Remember that hreflang must be reciprocal: every version, including the x-default target, should carry the full set of alternate links back to all the others.

• 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.
