abclonal.com website review

40 files are served with short cache lifetimes, so returning visitors download them again (9.2 MB).

10 images could be 2.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 9.2 s faster on a phone.

Your mobile performance score is 34. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.4 s on main-thread work while loading, 4.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Drift and Clarity and others), adding 1.4 MB and 1.6 s of main-thread time.

About 412 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

17 long tasks block the main thread while loading, the longest for 1.1 s. During a long task the page ignores taps.

Google Tag Manager costs a phone 831 ms of main-thread work and 528 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.

Drift costs a phone 574 ms of main-thread work and 813 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 35 KiB of CSS is downloaded but never applied on this page.

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.

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 wait 11.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.40 (75th percentile). Good is under 0.1.

Real visitors see the first content after 10.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 5.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 60.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 15.8 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 60.8 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.5 s in total while the page loads. Good is under 200 ms.

Real visitors wait 394 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 234 ms to 242 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 5.1 s to 5.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 11.6 MB in 294 requests on a phone: images 9.2 MB (37), scripts 1.7 MB (122) and other files 354 KiB (92). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 3.27 g of CO₂e: 392.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 buttons have no accessible name, so screen readers announce just “button”.

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

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

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

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is 77 characters, so Google will cut it off around 60: “Antibodies, Enzymes, Proteins, ELISA and Reagents for Life Science | ABclonal”.

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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

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

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.

Large scripts ship without source maps.

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.

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.

abclonal.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.

abclonal.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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 0 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

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.

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.
