topdon.com website review

Not measured in this review.

• Fails Core Web Vitals for real visitors

  Real Chrome users on phones do not pass Google's Core Web Vitals on your site (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

• Real-user CLS: 0.17

  0.17

  For real visitors the layout shifts by 0.17 (75th percentile). Good is under 0.1.

• Page weight: 12.8 MB

  12.8 MB

  Your homepage downloads 12.8 MB on a phone, 36 KiB of it images (0%). Under 2 MB keeps phones on slow connections fast.

• About 3.6 g of CO₂ per visit

  3.62 g

  By the Sustainable Web Design model, a visit to your homepage emits about 3.62 g of CO₂e: 434.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• Documents must have <title> element to aid in navigation (1 element)

  Documents must have <title> element to aid in navigation: 1 element on the page fails this check, rated serious by axe-core.

  Elements (1)

• <html> element must have a lang attribute (1 element)

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

  Elements (1)

• 21 images without alt text

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

  View source

• No main landmark

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

  Elements (1)

• Zoom is disabled

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

  Elements (1)

• Page should contain a level-one heading (1 element)

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

  Elements (1)

• No H1 headline

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

• Title is long (100 characters)

  Your title is 100 characters, so Google will cut it off around 60: “TOPDON Global | Pro Diagnostics, Battery Service, Thermal Imaging – HK TOPDON TECHNOLOGY …”.

  View source

• Meta description is long (313 characters)

  Your meta description is 313 characters; Google truncates after about 160, so the end of your pitch is cut.

  View source

• 13 internal links, 8 external

  The homepage links to 13 pages on topdon.com and 8 external pages.

• 1 linked page is broken

  Your homepage links to /user.html, which answers with an error. Visitors hit a dead end and search engines drop it.

  Elements (1)

• 4 pages share a title

  /pages/tools/diagnostic-tools, /pages/tools/battery-service, /pages/tools/thermal-imagers and /pages/tools/other-tools all use the title “TOPDON Product Collections – HK TOPDON TECHNOLOGY CO.，LIMITED”. Search engines can't tell which page to show for a search, so each competes with the others.

  Elements (4)

• 4 pages share a meta description

  /pages/tools/diagnostic-tools, /pages/tools/battery-service, /pages/tools/thermal-imagers and /pages/tools/other-tools use the same meta description. A description written for each page earns more clicks.

• 8 pages without an H1

  /pages/my-profile, /pages/my-devices, /pages/message, /pages/tools/diagnostic-tools, /pages/tools/battery-service and /pages/tools/thermal-imagers and 2 others have no <h1> headline, so visitors and search engines get no clear main topic.

• 9 internal pages checked

  We fetched 9 pages linked from your homepage and read each the way a search engine does.

• 1 JavaScript error while loading

  1 error was logged to the browser console while the page loaded, for example “Cannot read properties of null (reading 'addEventListener') theme.Drawers.Drawer.init (https://www.topdon.com/cdn/shop/…”.

• 1 broken link to your own pages

  1 link from your homepage to your own site is broken, for example https://www.topdon.com/user.html (404).

• Short HSTS lifetime

  HSTS is set, but max-age is 91 days; one year is the recommended minimum.

• 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.

• Deprecated X-XSS-Protection

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

• No security.txt

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

• No call to action on the first screen

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

• 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 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 154 words

  The homepage has only about 154 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.

• Email authentication score: 85/100

  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.

• 4 cookies set on arrival

  4

  Opening the homepage sets 4 cookies, 1 of them by other companies (measured from a US location before any click).

• No consent tool detected

  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.

• 8 other companies contacted

  Loading the homepage contacts 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
