skyscanner.net website review

11 files are served with short cache lifetimes, so returning visitors download them again (385 KiB).

About 377 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (skyscnr.com, px-cloud.net and New Relic and others), adding 1.3 MB and 779 ms of main-thread time.

skyscnr.com costs a phone 604 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.

A phone's processor spends 2.8 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,537 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

13 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 250 ms faster on a phone.

About 38 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

13 long tasks block the main thread while loading, the longest for 164 ms. During a long task the page ignores taps.

1 image could be 42 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 21 KiB JavaScript that modern phones do not need.

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.

Your largest element takes 10.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Search with AI Now you can search by telling us exactly wha…”.

The page becomes fully interactive after 11.7 s. Good is under 3.8 s.

Real visitors wait 3.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 217 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 392 ms in total while the page loads. Good is under 200 ms.

4 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' largest content (lcp) went from 4.0 s to 3.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.54 g of CO₂e: 64.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements with visible text labels do not have matching accessible names. (4 elements).

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

Your title is 71 characters, so Google will cut it off around 60: “Compare Cheap Flights & Book Airline Tickets to Everywhere | Skyscanner”.

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

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

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 https://www.skyscanner.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.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

Large scripts ship without source maps.

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 48 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.

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 7 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.
