tsaast.com 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.

• 1 image over 500 KB

  bg-process-day.jpg weighs 965 KiB. On a phone connection a single image that size takes seconds.

  Elements (1)

• 2 images far larger than shown

  967 KiB

  2 images are downloaded at several times the size a phone draws them, for example bg-process-day.jpg at 2,752 px wide, shown at 342 px. Resized copies would save about 967 KiB.

  Elements (2)

• Page weight: 2.8 MB

  2.8 MB

  Your homepage downloads 2.8 MB on a phone, 2.2 MB of it images (77%). Under 2 MB keeps phones on slow connections fast.

• 3 images in older formats

  3 images (1.4 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

  Elements (3)

• About 0.8 g of CO₂ per visit

  0.79 g

  By the Sustainable Web Design model, a visit to your homepage emits about 0.79 g of CO₂e: 95.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• 3 text elements with low contrast

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

  Elements (3)

• All page content should be contained by landmarks (10 elements)

  All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

  Elements (3)

• Headings skip levels

  Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

• Title is short (26 characters)

  Your title is only 26 characters: “TSA Co., Ltd. - 산업용 계측 솔루션”. 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.

• 3 H1 headlines

  There are 3 <h1> headlines (“정밀 계측의 기준,TSA”, “석유화학 플랜트를 위한계측 솔루션” and “선박·해양 분야전문 계측 제품”). One clear main headline is easier for people and search engines.

• 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://tsaast.com/sitemap.xml, so Google discovers your pages only by following links.

• No robots.txt

  There is no robots.txt at tsaast.com/robots.txt, the first file search crawlers ask for.

• 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.

• 73 internal links, 0 external

  The homepage links to 73 pages on tsaast.com and 0 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 https://tsaast.com/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.

• Your server turned our page checks away

  6 pages we tried to fetch timed out or refused automated requests, so these checks couldn't run. Some firewalls do this to every bot, including search engine crawlers they don't recognise.

• 3 small tap targets

  3 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

• 2 JavaScript errors while loading

  2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

• 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 analytics detected

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

• Only about 114 words

  The homepage has only about 114 words of visible text; thin pages give Google and first-time buyers little to go on.

• No form on the homepage

  There is no form on the homepage, so every lead has to click through to another page first.

• 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 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.

• 3 other companies contacted

  Loading the homepage contacts 3 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
