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

• Title taghigh impactlow effort

  <title> is "超凡国际(中国)官网-超凡国际App下载入口" (22 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.

• Canonical URLmedium impactlow effort

  Canonical href is "https://www.app-cn-chaofan.com/" (host www.app-cn-chaofan.com does not match page host app-cn-chaofan.com)

  This canonical tells search engines that another host owns the content, so they will typically index that URL and drop this one from results entirely. Unless this is deliberate syndication, update the href to this page's own URL on its own host — and make sure www vs non-www matches your preferred domain. The usual cause is a template copied between environments, so check that a staging or legacy domain isn't hard-coded in the site layout.

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.

• Word counthigh impactlow effort

  223 words of visible text

  Under 300 words, search engines typically classify a page as thin content, and thin pages rarely rank for anything competitive. Decide which query this page should answer, then write substantive copy — aim for 600+ words covering what it is, how it works, common questions, and concrete examples. If the page genuinely has nothing more to say, merge it into a stronger related page with a 301 redirect rather than padding it with filler that helps no one.

• Image alt textmedium impactlow effort

  6 of 31 images have alt text

  Alt text is how search engines understand what an image shows — it feeds image-search rankings and is what screen readers announce to blind visitors. Add a short, specific alt attribute to every meaningful image, describing the content rather than listing keywords: alt="Golden retriever puppy playing in snow" beats alt="dog puppy pet animal". Give purely decorative images an empty alt="" instead of omitting the attribute, so assistive technology knows to skip them rather than reading out the filename.

• 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.
