Why is a performance budget key to your web performance success?

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.

Fasterize now supports Let’s encrypt

There has been much talk about HTTPS lately. It is not just an advantage, it has become a must-have (for privacy and security of course, but for SEO as well).
HTTPS used to be expensive and hard to implement, Let’s encrypt has changed the deal.
It is a free, automated, and open certificate authority (CA) that provides SSL certificates, with a 3 months validity (renewable). Let's Encrypt offers a way to support a more secure and privacy-respecting Web, which is the reason why it was dear to us to support them and make it easier for our clients to use Let's Encrypt.

Third party tags: their impact on web performance

Webperf and third parties study

An increasing number of third party services are now being incorporated into today's web sites. In 2012, a typical web page contained an average of 13 third party scripts or "tags". Today, our Top 40 analysis of French e-commerce web sites shows that this number has risen to an average of 21 third party tags, an increase of 62%.

These third party services provide added value, with the promise of increased revenue (e.g. via advertising), higher conversion rates (through the use of retargeting tags) or a better understanding of user profiles (through embedded analytics).

But they also have a poor reputation when it comes to their impact on performance! A number of studies have attempted to prove this in the past (including studies such as those conducted by Instart Logic and NCC Group), and it forms a key part of the rationale behind ad blockers (a topic we will come back to in a future article).

We were keen to find out just how much of an impact these various third party widgets would have on the monthly web performance rankings published on JDN.
