pelagobio.com website review

About 1.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.3 s faster on a phone.

7 files are served with short cache lifetimes, so returning visitors download them again (221 KiB).

8 third-party services load with your homepage (Google CDN, YouTube and Hubspot and others), adding 2.6 MB and 1.2 s of main-thread time.

Your mobile performance score is 57 (desktop: 75). Pages that score under 90 lose visitors before the first paint.

About 138 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google CDN costs a phone 454 ms of main-thread work and 1.1 MB 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.

YouTube costs a phone 425 ms of main-thread work and 966 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.

A phone's processor spends 3.4 s on main-thread work while loading, 2.1 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 138 ms. During a long task the page ignores taps.

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.

Polyfills for old browsers add 4 KiB JavaScript that modern phones do not need.

Your largest element takes 10.8 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 17.9 s. Good is under 3.8 s.

Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 437 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 3.3 MB in 63 requests on a phone: scripts 2.3 MB (28), other files 359 KiB (9) and images 176 KiB (13). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (20 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.93 g of CO₂e: 111.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

1 frame has no title, so screen-reader users cannot tell what it contains.

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

There is no robots.txt at pelagobio.com/robots.txt, the first file search crawlers ask for.

The homepage links to 79 pages on pelagobio.com and 4 external pages.

There is no https://www.pelagobio.com/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 45 found) and read each the way a search engine does.

5 of 12 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

Chrome logged issues while loading the page (“Cookie”).

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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

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.

The homepage carries about 478 words of visible text.

Before a visitor clicks anything, the page loads Google Ads 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, 1 of them by other companies (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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
