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

• Title taghigh impactlow effort

  <title> is "91国产视频 - 原创国产内容在线观看" (19 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.

• Word counthigh impactlow effort

  142 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.

• Heading hierarchylow impactlow effort

  Heading level jumps from h2 ("支持按联赛和球队筛选") to h6 ("即时赛事数据")

  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.

• Fast time to first bytehigh impactmedium effort

  2388 ms

  Time to first byte is the floor under every other speed metric — the browser can't parse, render, or fetch anything until the first byte arrives, so a slow TTFB drags down all Core Web Vitals and tests crawlers' patience. Add caching in front of the origin: full-page caching at a CDN (Cloudflare, Fastly) helps most, followed by server-side caches (Redis, object caching) and indexes on slow database queries. Measure from locations near your actual users — tuning only your fastest region leaves distant visitors just as slow.

• 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.
