third-eye.tech website review

About 175 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

3 third-party services load with your homepage (Google Tag Manager, Google Fonts and Google Analytics), adding 245 KiB and 135 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 98 ms. During a long task the page ignores taps.

2 images could be 62 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

Your largest element takes 6.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “使うほど進化する デザインチェックツール。”.

The page becomes fully interactive after 6.2 s. Good is under 3.8 s.

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.18 g of CO₂e: 21.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

1 visible link has no text or label, so screen readers cannot say where it goes.

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

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

Your meta description is only 40 characters: “デザイナーのチェック作業を効率化し、AIと共にクリエイティブレベルを引き上げる。”. 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 XML sitemap at https://third-eye.tech/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at third-eye.tech/robots.txt, the first file search crawlers ask for.

The homepage links to 6 pages on third-eye.tech and 1 external page.

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 https://third-eye.tech/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.

/, https://third-eye.tech/legal/privacy and https://third-eye.tech/legal/commerce all use the title “Thirdeye | 誰でも気軽にデザインフィードバックを受けられる”. Search engines can't tell which page to show for a search, so each competes with the others.

https://third-eye.tech/legal/privacy and https://third-eye.tech/legal/commerce use the same meta description. A description written for each page earns more clicks.

https://third-eye.tech/legal/privacy and https://third-eye.tech/legal/commerce 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.

We fetched 2 pages linked from your homepage and read each the way a search engine does.

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.

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

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.

The homepage has only about 39 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 2 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
