baidu.com website review

Your mobile performance score is 88 (desktop: 91). Pages that score under 90 lose visitors before the first paint.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

2 images could be 41 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

1 file is served with short cache lifetimes, so returning visitors download them again (22 KiB).

About 32 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 98 KiB of JavaScript is downloaded but never used on this page.

2 third-party services load with your homepage (bdstatic.com and bcebos.com), adding 258 KiB and 53 ms of main-thread time.

Polyfills for old browsers add 11 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Visually, the page fills in at 21.1 s (Speed Index). Good is under 3.4 s.

2 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 103 ms to 101 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.08 g of CO₂e: 9.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

15 images have no alt text, which hurts accessibility and image search.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 9 characters: “百度一下，你就知道”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is only 61 characters: “全球领先的中文搜索引擎、致力于让网民更便捷地获取信息，找到所求。百度超过千亿的中文网页数据库，可以瞬间找到相关的搜索结果。”. 70 to 160 characters is enough to sell the click.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.baidu.com/sitemap.xml, so Google discovers your pages only by following links.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 19 pages on baidu.com and 36 external pages.

Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

/ and /s all use the title “百度一下，你就知道”. Search engines can't tell which page to show for a search, so each competes with the others.

/more, /duty and /licence have no meta description, so Google writes the search snippet from whatever text it finds.

/more, /s and /licence have no <h1> headline, so visitors and search engines get no clear main topic.

/more and /duty have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

/duty took over 3 s to send its HTML from our server.

We fetched 4 pages linked from your homepage and read each the way a search engine does.

No viewport meta tag, so phones render the desktop layout zoomed out.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

HSTS is set, but max-age is 2 days; one year is the recommended minimum.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1;mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

baidu.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

baidu.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 6,386 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Opening the homepage sets 3 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
