About a year ago, I have published an article about HTTPs usage growth: Chrome, Firefox and Google Search: HTTPS forcing its way. In this article I detailed some major announcements, that would probably result in pushing HTTPs forward.
Ever since, requests using HTTPs reach 25% according to HttpArchive data (compared to 15% in April 2015).
In this post, we’re going to focus on today’s results of the previous announcements, on the last changes, and especially on why you should consider HTTPs as a requirement for your website (not only for security or SEO considerations!)
It’s not usual on this blog, but today I’m going to write about a proposal that might become real, but that is still at its very early stage.
It is now more than a year since we added a recommendation about Content Security Policy with our website analysis on dareboost.com. It’s a great feature to add more security to your website, particularly to prevent your visitors from the effects of an XSS attack.

More and more of you were asking for it, so we did it :)
Comparison Tests are now available!
- Would you like to know how your website is doing compared to a competitor, whether it is a challenger or the leader of your market?
- Would you like to valorize your optimization work by comparing the new version and the old one of your client’s website?
- Would you like to compare the speed of the mobile and desktop versions of your responsive website?
The hosting is one of the key elements to a successful website. It is not only a parameter that can highly affect your website’s loading time (meaning your business success), but a host is also a partner upon who you should be able to rely on in time of crisis. Continue reading
Some days ago, we mentionned on this blog the various measures which the Performance Timing API provides access.
Today, I offer to you to discover other data required to assess the web performance, more focused on the user’s feeling than on the technical side. Continue reading
Latency is a notion little-known. Yet it strongly impacts the loading time of a website. In this blog post, I’m going to explain several things: what is the latency ? What are the effects to expect on the loading time of a page ? How to minimize its impact ?
