Website speed has long been a weak point across the travel sector. Back in 2020, an analysis of 200 travel websites showed many struggled to load quickly, particularly on mobile devices. Six years on, the picture is improving – but there is still a significant opportunity to do better.

Using Google’s PageSpeed Insights tool to reassess a range of UK travel brands, the average combined desktop and mobile score has risen to 109 out of 200, compared with 79 in 2020 – an improvement of around 38%.

While that represents real progress, it also highlights many sites still have work to do. In Google’s terms, a score just over 100 still indicates relatively modest performance.

For travel agents and tour operators, this matters more than ever because mobile browsing now dominates early-stage travel planning. Holidaymakers increasingly research destinations, compare options and browse inspiration on their phones throughout the day.

If a site loads slowly or feels unstable, potential customers often abandon it before they even reach the enquiry or booking stage.

Speed can also have a direct commercial impact. Research by Deloitte found that improving mobile site speed by just 0.1 seconds can increase travel conversion rates by more than 10%.

In other words, relatively small improvements translate into measurable revenue gains.

What separates faster travel websites

One clear pattern emerges when analysing site performance: websites that perform well on mobile tend to perform well on desktop too. This usually reflects strong technical foundations, including:

•    Efficient image handling
•    Controlled use of scripts and plugins
•    Stable page layouts that don’t jump while loading
•    Reliable hosting and caching infrastructure

Brands that improved dramatically over the past six years often did so through major changes such as website rebuilds, platform upgrades or a significant clean-up of outdated scripts and assets.

However, major rebuilds aren’t always necessary. Many performance gains can come from smaller technical improvements.

Practical ways to improve site speed

For travel businesses reviewing website performance, a few key areas typically deliver the biggest impact:

Optimise images: Travel websites rely heavily on imagery, but oversized photos are one of the most common causes of slow loading. Compressing images and using modern formats can dramatically reduce page weight.

Audit third-party scripts: Tracking tools, chat widgets and marketing plugins can quietly accumulate over time. Each script adds loading time, so removing unnecessary ones can provide an immediate boost.

Defer non-essential code: Ensuring only the critical parts of a page load first helps visitors start interacting with a site faster.

Stabilise layouts: Elements that shift around during loading create a poor experience, particularly on mobile devices.

Review hosting and caching: Slow servers or inefficient caching often affect booking engines and search results pages.

Set a performance budget: Establishing limits for page size or loading time helps keep performance on track as new features are added.

Speed is only part of the picture

While performance is important, it should be viewed as part of a broader digital experience. Even a fast website will struggle to convert if navigation is confusing, booking journeys are overly complex or mobile layouts feel cramped.

A simple way to think about it is:
•    Speed gets visitors in
•    User experience keeps them there
•    Clarity helps them book

The latest data shows travel websites are moving in the right direction, but the gap between average and high-performing sites remains wide.

For travel agents and tour operators competing in a crowded online market, investing in site performance is one of the simplest ways to improve both visibility and conversion.
