Frequently Asked Questions


Why should I care about my website optimization?

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 best practices, what are their purpose?

The rules applied by Dareboost aim at checking the compliance of your web pages with the latest best practices in web development. Dareboost provides you with the best practices recognized by the leading actors in the sector (including Google and Yahoo) and also guides you in the use of technologies detected on your website to ensure an optimal loading time.

Is it possible that my score changed without any modification on my website?

Dareboost is updated regularly to include new features and improvements. Our best practices change frequently, either by integrating new rules or by improving existing ones. It is likely that your score is affected by these changes.

How to read an analysis report?

An analysis report is divided into two parts:

  • The first part is a summary with several indicators, such as the overall score given by Dareboost to the page, its loading time, but also the number of problems found. The summary provide a quick overview of the quality and performance of your web page. This section also gives you access to detailed information such as the details of the steps of the loading time.
  • The second part begins with the different categories of best practices for your web page. Each category has a mark. It allows you to quickly identify the weakness of your web page and access to the associated advice. These tips are sorted by importance to determine your priorities. Each tip provides an explanation of the issues according to the context, the origin of the problem and how to fix it.

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.

Who has access to reports generated by Dareboost? Can I share a report?

Each of our reports has a single address, like "". You can share this address with anybody to provide them access to the report. Reports generated in "private mode" (available in the advanced settings) are only accessible by you. You cannot share them. Registered users also have the ability to generate a PDF version of their reports (a white label feature is available too) to send it by e-mail or other methods.

Best practices

What do the best practices' categories mean?

The best practices are grouped into categories to let you have a better understanding of the web page performance issues. Here is a list of these categories:

  • Accessibility: Improve the use of your site, especially for the visually impaired (eg allow a voice synthesis software to read the contents of your website).
  • Browser rendering: render the page as soon as possible.
  • Cache policy: The cache mechanism avoids downloading the same source several times between several connections. Aims at improving your visitors’ navigation and future session.
  • Compliance: All browsers do not treat the information in the same way. Be vigilant that your page is usable for the major browsers that your visitors use.
  • Data amount: A significant amount of data implies a higher loading time. So reduce the weight of the data sent over the network to improve the loading time, and reduce the bandwidth consumed by your server.
  • Number of requests: Each HTTP request has a performance cost (round trip time, bandwidth usage ...) so try to limit their number.
  • Quality: Best practices that facilitate the maintenance of your website or that are of general interest.
  • SEO: Improve your SEO, i.e. take care of your ranking in the Search Engine Results Page (SERP).
  • Security: Ensure the security of your website and your visitors.

Depending on the technology detected on your website, you will find a variable number of additional categories. We try to check up the best practices of your favorite technologies.

You have suggested a best practice that seems wrong/irrelevant, what can I do?

You can help describe the problem by consulting your online reports, using green and red thumbs (on the left of the tips). If the advice helped you, use the green thumb. Otherwise, if the advice seemed wrong, you can report it by voting negatively with the thumb down. You will be asked to give more information to help us improve the service.

How can I suggest a new best practice or an improvement?

We listen to all of your suggestions. You can suggest us a best practice ideas by contacting us. We will respond as soon as possible.

Advanced usage

Can I test a mobile version of my website?

Yes, Dareboost offers the possibility to simulate a smartphone user (select a mobile browser), and assign a 3G bandwidth. You will be able to measure the performance of your page in such configuration and access best practices dedicated to mobile sites or responsive web design.

Is it possible to analyze a web page that requires authentication?

Yes, it is, the ".htaccess" tab in the advanced settings allows you to specify a username and a password to analyze the pages that require basic authentication.

How do I measure the performance of my website with different bandwidths?

Our professional offers allow you to configure different bandwidth for an analysis to simulate your users' internet connection. You can select one of our pre-configured bandwidth (3G, ADSL, fiber) based on the averages recorded for the country of the chosen test location, or define a totally customized one.

I would like to know more about the “data form” advanced settings.

The "data form" tab allows you to integrate HTTP POST data in the request analysis. This data, sent in “key = value” format, is often used to transmit the data filled in a form on your page. For instance, you can test a web page that is only reachable after submitting a form. You can also check the performance variation depending on the fields values.

Does the service have an API?

Dareboost has an API that allows to perform basic actions: launch an analysis, obtain the report of the analysis or get the latest report for one of your monitored pages. If you want to have an access to the API, do not hesitate to contact us. For further information, please visit our technical documentation. We also have a java client to facilitate your use of the API.

Technical functioning

How is my website analyzed?

When you launch an audit, Dareboost simulates a visitor on your page, using a real browser (Chrome, Firefox) on the selected location. The service offers several advanced settings to simulate the different configurations and behaviors of your visitors. Throughout the loading of the page, we collect data over the network and performance metrics. Once the data is collected from your website, Dareboost executes its best practices engine, which detects the technologies used by the page (PrestaShop, Magento, Apache, jQuery, etc.), generates personalized optimization tips, and determines your priorities. Then you can access to the full quality and web performance report.

Is Dareboost using external services?

Dareboost uses well-known technologies such as Google Page Speed and W3C validator. We have our own installations of these tools and are, therefore, not dependent on third parties. We also integrate the best practices of YSlow! (edited by Yahoo!) in our best practices pool.

Analysis errors

Dareboost shows me an error "401 Unauthorized" when I try to run an analysis.

The 401 or Unauthorized error message is returned by the server when the web page you want to analyze requires an authentication.
Dareboost allows you to analyze such pages thanks to its advanced settings. These are available at the bottom of the analysis form. The "Htaccess" tab allows you to enter a login and a password. The information is encrypted and stored by Dareboost. You should generate a test login/password pair to use this feature.

Dareboost shows me an error "404 Not found" when I try to run an analysis.

Dareboost does not find the page you are trying to analyze:

  • Check you have entered the address correctly;
  • Use your web browser to check that the page behind the URL you have given to Dareboost is available;
  • Maybe you are trying to analyze a page that is not reachable from the Internet (local network?)

Dareboost shows me an error "403 forbidden" when I try to run an analysis.

The server is refusing to respond to the request sent by Dareboost.
Your server/hosting provider may have put Dareboost’s server in a blacklist. Or your web page is only reachable from your local area network.

Dareboost shows me an error "500 Internal Server Error" when I try to run an analysis.

The server returned to Dareboost that an error occurred while it was trying to generate the response.
Check if you can access the page you want to analyze with your browser. If your browser returns you the same error, come back later and launch the analysis again.
