4 resources are unreachable

You should avoid requesting unreachable resources.

Warning notifications that some requests related to your page are encountering errors can be due to:

  • errors in your HTML, CSS, or JavaScript resources;
  • an unhandled error on the server side;
  • or a problem on a service used by your page.

The following HTTP codes were returned:

These errors can affect content on and behaviors of your website and cause unnecessary network traffic, which affects the loading time of your page.

Save 27 requests using CSS sprites

Combining images into CSS sprites reduces the number of files the browser has to download and accelerates the loading time.

CSS sprites explained

A CSS sprite is a single file in which several smaller images are grouped and positioned one beside the other. You can display each small image in your page by applying CSS styles, and a single request is necessary to recover all the images. Use this method only for small images, such as icons, so the CSS sprite is not too heavy.

Example

Here is a CSS sprite example :

CSS sprite example

The page also applies the styles associated with the sprite:

.sprite {
background-image: url(img/sprite.png);
background-repeat: no-repeat;
display: block;
}

.sprite-browsers-firefox {
width: 31px;
height: 28px;
background-position: -74px 0;
}

Then you have just to define the right class in your HTML file, and the icon appears:

<span class="sprite sprite-browsers-firefox"></span>
How should I create CSS sprites?

Their creation can be complex, so we recommend using tools that easily generate them for you. Here are a few sprite generators:


28 can be combined in a CSS sprite. Several domain names used by the page should use this technique:

Resources from livetrafficfeed
Resources from psnexpertsusa

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!

175.5KiB of JavaScript is parsed during initial page load. Defer parsing JavaScript to reduce blocking of page rendering.

Security 

0/100

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.

8 images (343kB) are loaded too early

Load images above the foldline first, that means all the images that are visible without any scroll of the page by the visitor.

Webpage and images

Images use to represent more than 60% of the total weight of webpages. By loading initially the only images that are visible without page scrolling, you’ll reduce bandwith consumption as for your server and your visitors. If an image has to display after any visitor’s action (as scrolling) , then you’d better load it on demand, when necessary (lazyloading).

How to set up lazyloading?

You can get informations concerning the features and plugins proposed by your page’s frameworks/CMS. You should find some easy-to-set solutions. Some Javascript libraries could help you to implement lazyloading too.

WordPress logoAs an exemple, with WordPress, you could install one of these extensions dedicated to images lazyloading.

8 images (343kB) loading can be delayed on this page, representing 63% of the total weight of all your images.

1 domain sends 312 bytes of cookies

HTTP cookies are used to track a user to costumize the page according to their profile. They are sent as a HTTP header from the web server to the browser. Then, each time the browser accesses to the server, it sends a request containing the cookie received at the first response. See more information.

Here, 1 domain sends 312 bytes of cookies:

Domain name: livetrafficfeed
  • PHPSESSID: 312 bytes distributed on 12 request(s)

You serve scaled images

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:

Good job! No image resize have been detected. This is ideal for reducing page weight and loading time.

On this page, 3 images are resized by less than 35%. This can be consistent in a Responsive Web Design website, so this best practice does not penalize the following resources, but please make sure that they do not affect the page performance:

This page does not load too much data (1.1MB)

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 : 49,71% of total weight
  • JavaScript : 34,28% of total weight
  • Font : 10,50% of total weight
  • CSS : 2,86% of total weight
  • Texts : 2,65% 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 43 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 43 links present in the page:

  • 36 internal links (83,72%)
  • 7 "follow" external links (16,28%)
  • No "nofollow" external link (0,00%)

Browser rendering 

100/100

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.

Cache policy 

100/100

You do not use too long inline scripts

Any script with a significant size should let the browser cached them in order to reduce loading time/improve performance of your returning visitor.

Inline scripts / cache policy

"inline" scripts allow to integrate easily small portions of scripts directly in the HTML code. Example:

<script type="text/javascript">
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']...,'/analytics.js','ga');
    ga('create', 'UA-11111111-1', 'mywebsite.com');
</script>

By doing so, you avoid making a request to the server to retrieve the resource. So inline scripts represent a performance gain if you want to integrate small scripts.

However, once a script has a fairly substantial size, we advise you to outsource it and perform a request to retrieve it. So you will benefit from the cache mechanism.

What should I do?

Outsource your scripts with more than 1500 characters in one or more separate files.

Apache 

100/100

Your Apache server version is not exposed

You are using Apache, but we are not able to detect the version. It is more difficult for a hacker to attack your website, because he does not know the version you use. This is a good practice.

There are two values to check if you want to hide your server version: the ServerSignature and the ServerTokens (/etc/apache2/conf.d/security file on a Linux server).

# Hide the version from the 'Server' HTTP Header.
# (e.g.): display only "Server: Apache"
ServerTokens Prod
# Don't add a trailing footer line under server-generated document,
# containing the server name and its version.
ServerSignature Off

However, keep in mind that the best way to protect your system from attacks is to regularly update your Apache server.
