comtech.com.cn website review

• Google's speed test didn't respond

  Google's speed test didn't respond for this site, so speed and Core Web Vitals are not measured here. Your full playbook measures them.

Not measured in this review.

• 35 images without alt text

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

  View source

• 26 links without text

  26 links have no text or label, so screen readers cannot say where they go.

• No page language

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

  View source

• No meta description

  No meta description, so Google writes its own snippet from whatever text it finds.

  View source

• No H1 headline

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

• Title is short (12 characters)

  Your title is only 12 characters: “科通| 科通技术官方网站”. Between 30 and 65 characters leaves room to say what you do and for whom.

• No structured data

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

• No canonical URL

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

• No social preview image

  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

  No XML sitemap at https://comtech.cn/sitemap.xml, so Google discovers your pages only by following links.

• No favicon declared

  No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

• No X (Twitter) card tag

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

• 72 internal links, 18 external

  The homepage links to 72 pages on comtech.com.cn and 18 external pages.

• No Organization structured data

  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.

• No llms.txt

  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.

• 2 pages share a title

  / and /enindex.html all use the title “科通| 科通技术官方网站”. Search engines can't tell which page to show for a search, so each competes with the others.

  Elements (2)

• 2 pages without a meta description

  /enindex.html and /product-mun/260.html have no meta description, so Google writes the search snippet from whatever text it finds.

  Elements (2)

• 2 pages without an H1

  /enindex.html and /product-mun/260.html have no <h1> headline, so visitors and search engines get no clear main topic.

• 1 page with very little text

  /product-mun/260.html has 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.

• 15 internal pages checked

  We fetched 15 pages linked from your homepage (of 34 found) and read each the way a search engine does.

• 2 broken external links

  2 links to other sites are dead, for example https://www.powerint.cn/zh-hans?segment=none (521).

• No HSTS header

  No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

• No Content-Security-Policy

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

• HTTP/1.1 only

  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.

• No clickjacking protection

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

• No X-Content-Type-Options

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

• No Referrer-Policy

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

• No Permissions-Policy

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

• No security.txt

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

• No CAA record

  comtech.cn 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.

• No calls to action

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

• No social proof

  No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

• No analytics detected

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

• No direct contact details

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

• Only about 31 words

  The homepage has only about 31 words of visible text; thin pages give Google and first-time buyers little to go on.

• No risk reducer

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

• No DMARC policy

  comtech.com.cn has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

• No DKIM key on the usual selectors

  We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

• Email authentication score: 40/100

  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.
