Things to improve

Data amount

3 images are resized on browser side

Images must not be delivered larger than they are actually displayed to avoid loading unnecessary data.

Resizing images explained

Resizing images on browser side to reduce their rendering size is not recommended.

For instance, if your image is set to render at 300px by 300px on a particular page, don't upload the original 1000px by 1000px version of that image to your page. Instead, resize/crop the image to fit the display size and then upload it to your site to decrease the page weight and loading time.

Using images with responsive designs or retina screens?

Responsive website designs and retina screens do not justify an image resizing. Even in such cases, some methods exist to deliver your pictures to the right size. We recommend reading the following resources:

Don't resize the following images:

On this page, 1 image is resized by less than 35%. This can be consistent in a Responsive Web Design website, so this best practice does not penalize the following resource, but please make sure that it does not affect the page performance:

1 critical dependency detected

The failure of a third-party content provider could bring an overall breakdown of your website.

Single Point Of Failure

A Frontend Single Point Of Failure (SPOF) is a critical dependency on a third-party content, that may block the entire display of your page in case of failure of the content provider.

As an example, if your web page uses a blocking script hosted by Google’s servers, then your page is reliant on any failure from this script. Please read this blog post dedicated to SPOF for more information.

How to avoid SPOF?

As far as possible, exclude any of these dependencies, even from renowned providers. If you have to use a third-party content, ensure that you choosed an asynchronous integration and that you have a fallback in case of problem.


We are checking if the tested web page depends (in a critical way) on some of most widespread external resources (googleapis, typekit,...). That are known as Frontend SPOF (Single Point Of Failure) cases.

This resource represents a SPOF for this page:

Defer parsing of JavaScript

JavaScript can significantly slow down a page display, especially if it is necessary to download an external script.

Defer the use of JavaScript as much as possible to provide a faster start for the page display.

How can I fix this?

First of all, distinguish what portions of your JS is critical and must be loaded as soon as possible, and put them in a specific external file. Keep this file as streamlined as possible, and defer the parsing or execution of all other JS files (learn more).

Use one of the methods below to defer parsing for external JavaScript files:

  • use the async attribute;
  • use the defer attribute;
  • append the script to the DOM in JavaScript during the onload event;
  • make sure your scripts are placed at the bottom of the page (ideally at the end of the body).

The WP Rocket Wordpress plugin has a "Load JavaScript deferred" option, feel free to try it!

116.9KiB of JavaScript is parsed during initial page load. Defer parsing JavaScript to reduce blocking of page rendering.

Security

You should use a secure connection (HTTPS)

HTTPS guarantees the confidentiality and security of communications over the internet: data is encrypted, so protected against attacks and data corruption.

Google is multiplying its actions to push more and more websites towards HTTPS. Google first added HTTPS in its SEO criteria (see the announcement). Since then, Chrome has been evolving and now highlights the absence of a secure environment in various cases where information is collected from users. Other browsers are also following this trend.

Setting up HTTPS on a website sometimes causes some reservations (cost, impacts on performance, compatibility with technical partners…). But the market has changed in recent years and you should not worry about migrating to HTTPS. You should consider switching your site to HTTPS.

How to set up the HTTPS protocol

You have to set up a certificate you got from a reliable certification authority. Learn more by contacting your website host who can help you getting this certificate. Besides, the following page help you in your migration procedure to the HTTPS protocol.

A free certificate? Try Let's Encrypt!

Let's Encrypt is a free, automated, and open certificate authority. Many hosting providers offer to enable the generation and automatic renewal of free certificates directly from the administration interface of your domain. Contact your website host for more information.

Data amount 

0/100

Identical resources are served from different URLs

Resources with identical content should be served from the same URL to avoid duplicate downloads and additional requests.
You can save 1 requests and 7,76kB of data

Different URLs for the same resource

If you use different URLs to serve identical content, browsers have to request this content from the server several times, and your page will trigger unnecessary requests for data. If the same URL is used, the browser will only send one request and will use the response wherever the resource is requested. You should also use the same URL to reference the same content on several pages to benefit from the cache mechanism.

How to fix this?

Serve each resource from a unique URL. If you have to request the same resource several times, the same URL should be used to retrieve it every time.


The following URLs lead to identical content. Serve these resources from the same URL to save 1 request(s) and 7,76kB of data.

Data amount 

This page does not load too much data (1.9MB)

A too high page weight slows down the display, especially on low speed connections. This can lead to frustration for users paying for data (see whatdoesmysitecost.com).

Evaluate the Weight of my Web Page

In February 2016, the average weight of 100 most visited websites in the world was 1,38MB.

How to reduce the weight of my page?

You can report to our "Data amount" category to discover the possible optimizations in your case. Images are often involved.
Moreover, make sure to build your web pages in order to load data that is essential to the user experience (rendering optimization of the critical path).
For other contents (social networking plugins, advertising, content at the bottom of the page ...), it is better to delay the loading (asynchronous, lazy-loading ...), so they don't override priority contents.

We strongly recommend that you define performance budgets before you carry out your web projects. These budgets can be settled through the Dareboost monitoring feature.


We have established the weight distribution of the page by resource type:

  • Images : 45,75% of total weight
  • JavaScript : 30,90% of total weight
  • CSS : 12,08% of total weight
  • Font : 10,50% of total weight
  • Texts : 0,78% of total weight

Here is the weight of the 10 heaviest resources over the network, and that are necessary to load the page:

This page contains 2 links

Two kind of links exist:

  • Internal links that refer to pages with the same domain name;
  • External links that point to other websites (must be relevant and point towards quality content).

If you reference many links, you can ask the SEO crawlers to consider only some of them, by adding the rel=nofollow attribute to the irrelevant ones (e.g., advertisements).

Here is the distribution of 2 links present in the page:

  • 2 internal links (100,00%)
  • No "follow" external link (0,00%)
  • No "nofollow" external link (0,00%)

10 resources on this page are for public use

By default, the browser accepts to perform AJAX requests, or to retrieve web fonts, only on the same domain name of the page. So a font provided by toto.com can only be used by the pages of toto.com. This prevents misuse of your resources by any site.

Some resources are public, and explicitly want to be available to everyone (eg Google Fonts). In this case, the HTTP header Access-Control-Allow-Origin can be used with the value "*". You should, however, use this property if your resource has aimed to be used by the greatest number. Otherwise, we recommend that you keep the default, or set a specific domain name in the "Access-Control-Allow-Origin" HTTP header.

You should be aware of the following resources, that use a Access-Control-Allow-Origin: * HTTP header. Make sure they are actually intended to be used by pages from all domain names:

It appears these files are hosted by a third-party, so they may not be within your control. However, you should consider any alternative to these resources to improve your page performance.

Your HTML response is not too heavy

Why reduce the code amount of a page?

Before a web page can be displayed, the browser must, among other things, download it, parse it and model it into a document that can be understood by the rendering engine. If the amount of code contained in the page is too large, these steps are slowed down and the rendering is delayed.

How to reduce the amount of code?

Your HTML response should contain only the information that is immediately necessary to display the visible area of the page. Move inline information to external files (JS for scripts, CSS for styles, asynchronous queries for additional content) and simplify the HTML structure of your page.

No empty element detected

<p>, <li>, <button>, <legend>, <caption>, <figcaption> and <quote> elements must not be empty because if they are, some screen readers will have difficulties interpreting their presence.

Remove these empty elements from you code or decorate them with the aria-hidden attribute so that the screen readers ignore them.

<p aria-hidden="true"></p>

Your <img> tags use an alt attribute, but 8 are empty

Moreover, the alt attribute is also an important criterion for SEO. Indeed, search engines crawlers cannot parse graphic contents. That is why they use the alternative text to return consistent results, like in Google images.

<img src="product.jpg" alt="My product description"/>

The alt attribute is used in several cases unrelated to SEO:

  • When a screen reader is in use for accessibility purposes;
  • While image is loading, particularly for slow connections;
  • When the image file is not found.

You have 9 img tags and they all have the alt attribute.

Warning, you should also note that 8 of your images contain an alt attribute, but they are empty:

  • <img width="465" height="349" src="http://ubezpieczenieturystyczne.online/wp-content/uploads/2018/09/6009621-1.jpg" class="attachment-large size-large" alt="" srcset="http://ubezpieczenieturystyczne.o...

If nothing seems appropriate for describing an image, you might set an empty text. We advise you to make sure the majority of your images define a relevant text. Read the W3C recommendations here.

This page uses only standard image formats

The images that use a non-standard format may not be indexed by search engines.

Only these image formats are considered standard on the web: jpeg, jpg, png, gif, svg, ico, webp. You should consider an alternative to any other format.

Moreover, remember to treat the text around your images: some search engines analyze approximately the 10 words preceding and following the image in order to add a context to the image.

No Java applets detected

Java applets are considered obsolete in 2015. HTML5 is powerful and more widely supported. Using Java applets can lead to compatibility issues and may send negative signals to your users (eg the browser indicating that content was blocked because it could be dangerous).

Congratulations, this page doesn't contain Java applets.
