TLS 1.3, the new and more efficient version of secure web

TLS 1.3

In August 2018, the Internet Engineering Task Force (IETF) approved the 1.3 version of TLS, a more secure and more efficient version.

How to organise your teams for maximum web performance

From users to marketing teams to CTOs, all would agree that loading speed is crucial for your web site. (Like many, has your CEO has also been asking why your web site is running slow as you’ve passed them in the corridor…?)

Why speed is key for m-commerce web sites

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?

Smart image optimisations to boost your 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.

4 crucial speed boosts for your HTTPS-enabled web site

HTTPS optimisations

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.
