amstar.com website review

About 396 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.8 s faster on a phone.

4 images could be 280 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 26 (desktop: 62). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

4 third-party services load with your homepage (Google CDN, Other Google APIs/SDKs and JSDelivr CDN and others), adding 963 KiB and 737 ms of main-thread time.

Google CDN costs a phone 628 ms of main-thread work and 733 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.

About 45 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 430 ms faster on a phone.

A phone's processor spends 3.0 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

12 long tasks block the main thread while loading, the longest for 205 ms. During a long task the page ignores taps.

40 KiB could be saved by minifying JavaScript.

2 files are served with short cache lifetimes, so returning visitors download them again (9 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

Desktop scores 62 but mobile only 26. A gap that wide usually means heavy scripts and images that hit phones hardest.

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

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 12.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Based in Denver, Colorado, Amstar is an institutionally own…”.

The layout shifts by 1.127 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The first text or image appears after 7.2 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 13.2 s. Good is under 3.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 324 ms in total while the page loads. Good is under 200 ms.

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.

Your homepage downloads 2.3 MB in 39 requests on a phone: images 915 KiB (12), scripts 904 KiB (16) and other files 351 KiB (3). Under 2 MB keeps phones on slow connections fast.

Amstar_logo_large-copy-1-720x210.jpeg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

3 images (182 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.66 g of CO₂e: 79.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA roles used must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

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

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

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

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 13 pages on amstar.com and 1 external page.

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.

/about-us, /investment-strategy, /portfolio and /offices have no meta description, so Google writes the search snippet from whatever text it finds.

/portfolio and /offices 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 5 pages linked from your homepage and read each the way a search engine does.

2 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

http://amstar.com does not redirect to https, so some visitors land on the insecure version.

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

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

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

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

Opening https://amstar.com goes through 2 redirects before the homepage loads.

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

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

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

amstar.com 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.

amstar.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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

The homepage has only about 160 words of visible text; thin pages give Google and first-time buyers little to go on.

The homepage shows no opening hours. If customers visit or call, show when.

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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

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.

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