registech.com website review

14 images could be 7.6 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 10.3 s faster on a phone.

31 files block the first paint until they finish downloading. Deferring or inlining them could save about 5.5 s.

About 592 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.8 s faster on a phone.

About 347 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.

8 files are served with short cache lifetimes, so returning visitors download them again (239 KiB).

Your mobile performance score is 39 (desktop: 55). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.2 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and searchiq.co and others), adding 1.3 MB and 1.2 s of main-thread time.

Google CDN costs a phone 574 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.

Google Tag Manager costs a phone 422 ms of main-thread work and 316 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.

29 KiB could be saved by minifying JavaScript.

18 long tasks block the main thread while loading, the longest for 178 ms. During a long task the page ignores taps.

25 KiB could be saved by minifying CSS.

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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

The page becomes fully interactive after 74.3 s. Good is under 3.8 s.

The first text or image appears after 6.8 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 10.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 671 ms in total while the page loads. Good is under 200 ms.

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

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 17.2 MB in 136 requests on a phone: images 14.4 MB (26), scripts 1.5 MB (62) and fonts 451 KiB (7). Under 2 MB keeps phones on slow connections fast.

6 images weigh 11.0 MB together. On a phone connection a single image that size takes seconds.

7 images are downloaded at several times the size a phone draws them, for example Blog-Sliding-Box-image-1920x1064-1.png at 1,920 px wide, shown at 324 px. Resized copies would save about 6.9 MB.

11 images (12.3 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.

4 images further down the page (4.5 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 4.87 g of CO₂e: 584.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

ARIA commands must have an accessible name: 3 elements on the page fail this check, rated serious by axe-core.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 3 elements on the page fail this check, rated moderate by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one main landmark: 1 element on the page fails this check, rated moderate by axe-core.

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

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

3 form fields have 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.

Alternative text of images should not be repeated as text: 3 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

The homepage links to 75 pages on registech.com and 2 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/online-ordering-temporarily-unavailable, /chiral-hplc-sfc-columns and /achiral-sfc-columns have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /bioluminescent-reagents, whose canonical is /imaging-reagents. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/blog and /news have no <h1> headline, so visitors and search engines get no clear main topic.

/bioluminescent-reagents took over 3 s to send its HTML from our server.

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

1 image failed to load on a phone, for example https://regischrom.com/wp-content/uploads/2024/06/DSC_9784_withRegis-Patch_White-teflon-tape-fixed1920x1064.png.

10 of 39 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

2 links from your homepage to your own site are broken, for example https://regischrom.com/4-chloro-1-naphthol (404).

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.

1 link go through two or more redirects, for example https://regischrom.com/bioluminescent-reagents.

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.

regischrom.com was registered in Jul 2026 through IONOS SE. Spam filters and search engines treat brand-new domains more cautiously, so expect email and rankings to take a few months to settle.

regischrom.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.

regischrom.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.

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.

Social proof on the homepage: 2 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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.

The homepage carries about 289 words of visible text.

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

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 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 15 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 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
