kotaxdev.com website review

4 third-party services load with your homepage (Google Tag Manager, Cloudflare and tally.so and others), adding 204 KiB and 202 ms of main-thread time.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

2 long tasks block the main thread while loading, the longest for 123 ms. During a long task the page ignores taps.

About 95 KiB of JavaScript is downloaded but never used on this page.

Polyfills for old browsers add 35 KiB JavaScript that modern phones do not need.

3 images could be 25 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 files are served with short cache lifetimes, so returning visitors download them again (17 KiB).

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

Visually, the page fills in at 3.6 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 0.14 g of CO₂e: 16.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

4 visible links have no text or label, so screen readers cannot say where they go.

Alternative text of images should not be repeated as text: 2 elements on the page fail this check, rated minor by axe-core.

Your title is only 24 characters: “Kotaxdev by Asrul Hanafi”. Between 30 and 65 characters leaves room to say what you do and for whom.

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 190 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 10 pages on kotaxdev.com and 10 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 3 pages linked from your homepage and read each the way a search engine does.

1 image is served at too low a resolution for sharp phone screens.

1 link from your homepage to your own site is broken, for example https://kotaxdev.com/cdn-cgi/l/email-protection (404).

1 link to other sites is dead, for example https://www.linkedin.com/in/asrul-h/ (999).

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.

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.

kotaxdev.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.

kotaxdev.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.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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.

The homepage carries about 514 words of visible text.

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