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

• Title taghigh impactlow effort

  <title> is "Sven Gillert, Gassenhauer Musik aus Berlin! Plattenfirma New World Records präsentiert" (86 characters)

  Search engines truncate titles past roughly 60 characters and often rewrite very short or vague ones, so the message you wrote may never actually be shown. Rewrite the title to 30–60 characters that lead with the primary keyword and end with your brand, e.g. "Merge PDF Files Online Free | YourBrand". Front-load the important words, since truncation always cuts from the end. Don't pad a short title with repeated keywords just to hit the range — clarity wins clicks, not length.

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 h4 ("NEWSLETTER") to h6 ("BLEIBE AUF DEM LAUFENDEN")

  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.

HTTPS, redirects, robots, sitemap, speed, crawlability.

• Short redirect chainmedium impactlow effort

  https://svengillert.com/ (302) → https://www.svengillert.com/en

  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.

• Missing pages return 404low impactlow effort

  missing paths return a non-404 status (soft 404)

  URLs that don't exist on your site return a success status instead of 404 — search engines call these soft 404s, keep recrawling them, and may index the useless placeholder pages, wasting crawl budget that should go to real content. Configure your server or framework to return an actual 404 status (or 410 for permanently removed content) along with your error page. The classic mistake is serving a friendly "page not found" template with a 200 status — crawlers ignore the visible message; only the status code counts.
