Setting up and maintaining a fast web site can be a hotly debated issue: should preference be given to in-house development, and where will it fit in an already busy development schedule?
There are now some 5.052 billion mobile users, accounting for 67% of the world's population. And with WiFi and 4G now widely available, the pace of mobile activity is continually on the rise: mobile web traffic is up 21% over the previous year.
Beyond its usefulness to consumers, mobile commerce offers key advantages from a business perspective:
- Tablet devices account for the highest add-to-cart rates on e-commerce websites at 8.58%. (Smart Insights)
- Average smartphone conversion rates are up 64% compared to the average desktop conversion rates. (CMS Report)
Alibaba is a prime example: “Mobile revenue for its Chinese e-commerce business increased 80 percent to US$13.18 billion, generating 80 percent of its total retail revenue in the country. Monetisation of its mobile commerce platforms outstripped that of desktop”.
Given this surge in mobile activity, there can be no doubt about it: e-commerce operators must eliminate any potential points of friction that users may experience on their web sites. Consumers are more demanding than ever and expect a slick and seamless experience. Speed is therefore among consumers' top requirements when it comes to the mobile experience. This then raises the question: how can we reduce loading times on our mobile web site?
It is often difficult to get the right trade-off between image quality and loading speed.
The ideal solution would be for each image to be adapted on a user-by-user basis: be that clipping it perfectly to the user's device screen, stripping metadata of any unnecessary information or, of course, ensuring that it is displayed with optimum image quality. But achieving this soon becomes something of a black art.
Given this challenge, our technical team has pored over the plethora of best practices and advanced libraries out there to ensure that Fasterize implements the very best in image compression algorithms.
In this article, we present an overview of the various methods used.
TLS (Transport Layer Security) encrypts traffic to and from a web site, thereby preventing other parties from eavesdropping on your data. However, adding this safeguard to your web site introduces greater complexity and affects how the site interacts with your visitors. TLS can therefore lead to slow page loading times and have a negative impact on user experience. In this article, we introduce the various optimisations implemented by Fasterize at the TLS security layer to ensure your web site remains slick while maximising security.
How much of an impact does font loading have on loading times? What is the best web performance strategy to adopt when it comes to optimising font loading? Anthony, one of our web performance experts, lifts the lid on some or our in-house analysis and gives the low-down on FOUT, preloading and inlining.

Web performance is a crucial factor for any ecommerce website, and CDN are among the many solutions available to improve this performance.

Waterfall charts provide a timeline representation of how elements of your web page are loaded into the browser.
This type of graph provides a wealth of information, including details such as the size of each of your resources, the number of requests, the loading behaviour, loading times and much much more!
So grab your
wetsuit webpagetest report, as we dive in and show you how to interpret your waterfall chart and uncover the clues it has to offer for improving the performance of your web site.
We enhanced our API to ease your server logs access.
You can now retrieve your cached page logs (whether there are cached on a CDN or on Fasterize) easily. A good news, especially for SEO professionals, who can find a lot of meaningful data in these logs. And, the icing on the cake, we are officially integrated with Botify and Screaming Frog!
Performance budgets have been around for a number of years (since 2013 to be precise) and have proven their worth over and over again. CTOs the world over have achieved and maintained performance targets by adopting one.
The budget in question is not the amount of money that you and many other web developers like you will be spending on achieving optimum performance this year. Rather, we will be taking a detailed look at the notion of ‘performance budget’. It is a concept that deserves to be more widely adopted by web site producers. Once you have set yours, you will probably wonder how you ever lived without it.
