gstarcad.net website review

94 files are served with short cache lifetimes, so returning visitors download them again (3.0 MB).

About 604 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 2.7 s faster on a phone.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.1 s.

Google Tag Manager costs a phone 1.7 s of main-thread work and 1.3 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 31 (desktop: 62). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.1 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Clarity and others), adding 1.7 MB and 2.3 s of main-thread time.

10 images could be 1.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

About 990 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

Facebook costs a phone 487 ms of main-thread work and 318 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.

18 long tasks block the main thread while loading, the longest for 466 ms. During a long task the page ignores taps.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

Polyfills for old browsers add 24 KiB JavaScript that modern phones do not need.

22 KiB could be saved by minifying JavaScript.

Desktop scores 62 but mobile only 31. A gap that wide usually means heavy scripts and images that hit phones hardest.

10 KiB could be saved by minifying CSS.

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

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

Real visitors see the first content after 3.2 s (75th percentile). Good is under 1.8 s.

Your largest element takes 10.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “GstarRender”.

The page becomes fully interactive after 34.3 s. Good is under 3.8 s.

Visually, the page fills in at 12.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.6 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 4.2 s on a phone. Good is under 1.8 s.

Real visitors wait 3.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 261 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 136 ms to 259 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

13 images have no width and height attributes, so the layout jumps as each one loads.

Your homepage downloads 5.3 MB in 239 requests on a phone: scripts 2.8 MB (107), images 1.9 MB (62) and stylesheets 483 KiB (15). Under 2 MB keeps phones on slow connections fast.

6 images are downloaded at several times the size a phone draws them, for example houseplan-icon29.png at 1,920 px wide, shown at 390 px. Resized copies would save about 840 KiB.

6 images (1.1 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.50 g of CO₂e: 180.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 14 elements on the page fail this check, rated moderate by axe-core.

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

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

7 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (4 elements).

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Your meta description is 210 characters; Google truncates after about 160, so the end of your pitch is cut.

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

9 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

6 links have no real href, so search engines can't follow them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 65 pages on gstarcad.net and 35 external pages.

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 /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.

We fetched 15 pages linked from your homepage (of 33 found) and read each the way a search engine does.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_TUNNEL_CONNECTION_FAILED”.

6 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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.

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

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.

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.

gstarcad.net 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.

gstarcad.net'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.

Social proof on the homepage: 6 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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

The homepage carries about 665 words of visible text.

gstarcad.net has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

DMARC is set to p=none, so mail pretending to be gstarcad.net is still delivered. Reports are on, so moving to quarantine is the next step.

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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity (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 14 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 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
