spllabs.com website review

5 images could be 603 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.0 s faster on a phone.

42 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.8 s.

Your mobile performance score is 60 (desktop: 68). Pages that score under 90 lose visitors before the first paint.

About 210 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

About 76 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

The page has 1,770 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

7 third-party services load with your homepage (Google Tag Manager, zi-scripts.com and Google/Doubleclick Ads and others), adding 268 KiB and 163 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

3 long tasks block the main thread while loading, the longest for 137 ms. During a long task the page ignores taps.

9 KiB could be saved by minifying CSS.

1 file is served with short cache lifetimes, so returning visitors download them again (6 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.

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

Real visitors see the first content after 3.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 3.0 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 12.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “SPL Science That Powers Progress”.

Visually, the page fills in at 10.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 13.4 s. Good is under 3.8 s.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.5 s to 3.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 77 ms to 85 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.4 MB in 110 requests on a phone: images 972 KiB (14), fonts 697 KiB (9) and scripts 576 KiB (35). Under 2 MB keeps phones on slow connections fast.

1 image (206 KiB) is 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.

1 image further down the page (206 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 0.68 g of CO₂e: 81.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 12 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

Contentinfo 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 contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

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

Your title is only 15 characters: “Home Page - SPL”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is 494 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 265 pages on spllabs.com and 3 external pages.

https://spllabs.com/energy-laboratories, https://spllabs.com/hydrocarbon-laboratory-capabilities, https://spllabs.com/energy-laboratories/flow-assurance, https://spllabs.com/energy-laboratories/flow-assurance/asphaltenes, https://spllabs.com/energy-laboratories/flow-assurance/corrosion and https://spllabs.com/energy-laboratories/flow-assurance/consulting-operations-support and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://spllabs.com/hydrocarbon-laboratory-capabilities, https://spllabs.com/energy-laboratories/flow-assurance/consulting-operations-support and https://spllabs.com/energy-laboratories/flow-assurance/rheological-studies took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 78 found) and read each the way a search engine does.

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

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

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 1,156 words of visible text.

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 9 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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
