A 1-second delay in page loading time can lead to 11% fewer page views, a 16% decrease in customer satisfaction, and 7% loss in conversions. (Source : Aberdeen Group).
Loading time impacts the income generated by online businesses. It affects, among others, the bounce rate, the conversion rate, the average basket ... By having a faster website than your competitors, you give yourself a good opportunity to increase your sales and, therefore, your market share.

What factors affect my website loading time?

Several factors affect your loading time, such as network performance or your hosting infrastructure, but 90% of these waiting times are front-end related (Source: High Performance Web Sites). It means that most of the loading times lie in what happens after the initial response from your web server (images, widgets, etc.). This must be one of your main areas of concern. That's why Dareboost is appointed to help you improve and monitor the performance and the quality of the front-end.

Dareboost provides a lot of tips, what should I do first?

Dareboost calculates the impact of each best practice. So the most important issues are placed at the top of your report. The list of best practices begins with the three priorities that you should fix to optimize your website. This sorting is systematically applied, whether you consult all of the advice or only those from a specific category.

How do you calculate my score?

Scores are indicators showing the degree of compliance with one or a group of best practices. We give two different types of scores, all between 0 and 100:

  • A score for each best practice: the more you respect the rule, the more your score is close to 100. These marks have a coefficient to determine what your priorities are.
  • The overall score of the page: this is the average score,taking into account the coefficients of each best practice.

How does performance monitoring work?

When you monitor a web page, an analysis is automatically launched at regular intervals. Dareboost allows you to monitor your web pages and receive alerts in case of problems.
These use repeated data collection to generate statistics, so you have a clear vision of the evolution of the performance and quality of your pages. You can find all this data in your dashboard after connection or in the weekly digest by e-mail.

Why should I monitor a web page?

Over time, your website faces many evolutions, not necessarily from you. The monitoring configuration not only allows you to see and respond to changes in the performance and the quality of your website over time but also allows you to set alerts to be notified by email as soon as a problem is detected.
