Speed
Render-blocking requests
2.6 s9 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.6 s.
Mobile performance score: 85
85/100Your mobile performance score is 85. Pages that score under 90 lose visitors before the first paint.
Reduce unused JavaScript
750 ms · 229 KiBAbout 229 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.
Weebly adds 214 ms
214 msWeebly costs a phone 214 ms of main-thread work and 514 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.
1 third-party service on the page
1 third-party service load with your homepage (Weebly), adding 514 KiB and 214 ms of main-thread time.
Reduce unused CSS
150 ms · 29 KiBAbout 29 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.
Use efficient cache lifetimes
148 KiB16 files are served with short cache lifetimes, so returning visitors download them again (148 KiB).
2 long tasks on the main thread
2 long tasks block the main thread while loading, the longest for 119 ms. During a long task the page ignores taps.
Font display
50 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).
Improve image delivery
39 KiB1 image could be 39 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Legacy JavaScript
11 KiBPolyfills for old browsers add 11 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Main-thread work: 0.3 s
A phone's processor spends 0.3 s on main-thread work while loading, 149 ms of it running JavaScript. That is comfortably low.
Server response: 1 ms
1 msYour server sent the HTML in 1 ms, well inside Google's 600 ms guideline.
Core Web Vitals
First Contentful Paint: 3.3 s
3.3 sThe first text or image appears after 3.3 s on a phone. Good is under 1.8 s.
Largest Contentful Paint: 3.3 s
3.3 sYour largest element takes 3.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Welcome to Nathan's page! We are Nathan's parents, and we h…”. Most of its time is element render delay (1.5 s).
Time to Interactive: 4.3 s
4.3 sThe page becomes fully interactive after 4.3 s. Good is under 3.8 s.
1 image without width and height
1 image have no width and height attributes, so the layout jumps as each one loads.
Not enough real-visitor data yet
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.
3 checks passed
Speed Index: 3.4 s
3.4 sVisually, the page fills in at 3.4 s (Speed Index), inside the 3.4 s “good” threshold.
Total Blocking Time: 99 ms
99 msScripts block the page for only 99 ms while loading. Good is under 200 ms.
Cumulative Layout Shift: 0
0The layout barely moves while loading (CLS 0, good is under 0.1).
Images and page weight
1 image in older formats
1 image (64 KiB) is 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.
About 0.2 g of CO₂ per visit
0.17 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.17 g of CO₂e: 20.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
Page weight: 616 KiB in 18 requests
616 KiBYour homepage downloads 616 KiB in 18 requests on a phone: scripts 427 KiB (6), images 85 KiB (3) and fonts 51 KiB (3). That is a lean page.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
Images must have alternative text (1 element)
Images must have alternative text: 1 element on the page fails this check, rated critical by axe-core.
All page content should be contained by landmarks (4 elements)
All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.
No main landmark
The page has no <main> landmark, so screen-reader users cannot jump straight to the content.
1 checks passed
18 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 21 WCAG 2.2 A/AA and best-practice rules on the phone render: 18 passed and 3 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No meta description
No meta description, so Google writes its own snippet from whatever text it finds.
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
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.
1 link crawlers can't follow
1 link has no real href, so search engines can't follow it.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.
7 internal links, 1 external
The homepage links to 7 pages on nathankao.com and 1 external page.
4 checks passed
Title: 33 characters
Your title is a healthy 33 characters: “Nathan Kao: Watch me grow! - Home”.
Open Graph tags complete
Open Graph tags are complete, so shared links show a title, description and image.
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
XML sitemap found
Your XML sitemap is reachable at http://nathankao.com/sitemap.xml.
AI search readiness
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://nathankao.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.
1 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Other pages
2 pages share a title
https://nathankao.com/index.html and / all use the title “Nathan Kao: Watch me grow! - Home”. Search engines can't tell which page to show for a search, so each competes with the others.
6 pages without a meta description
/, https://nathankao.com/about.html, https://nathankao.com/blog.html, https://nathankao.com/review.html, https://nathankao.com/resource.html and https://nathankao.com/contact.html have no meta description, so Google writes the search snippet from whatever text it finds.
6 pages without an H1
/, https://nathankao.com/about.html, https://nathankao.com/blog.html, https://nathankao.com/review.html, https://nathankao.com/resource.html and https://nathankao.com/contact.html have no <h1> headline, so visitors and search engines get no clear main topic.
5 pages with very little text
/, https://nathankao.com/about.html, https://nathankao.com/review.html, https://nathankao.com/resource.html and https://nathankao.com/contact.html 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.
6 internal pages checked

Best practices
No mobile viewport
No viewport meta tag, so phones render the desktop layout zoomed out.
1 checks passed
No console errors
No JavaScript errors were logged while the page loaded on a phone.
Content and conversion
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 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 50 words
The homepage has only about 50 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.
1 checks passed
1 call to action
The homepage has 1 call to action, for example “Contact”.
Privacy and tracking
3 cookies set on arrival
3Opening the homepage sets 3 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.
2 other companies contacted
Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at nathankao.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
