Reduce the page weight (4,54 MB)

The page weight is too high, slowing down its 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 : 69,45% of total weight
  • JavaScript : 25,36% of total weight
  • Texts : 3,22% of total weight
  • Font : 1,30% of total weight
  • CSS : 0,45% of total weight
  • JSON : 0,03% of total weight

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

4 images are resized with a width/height attribute

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

Resizing images explained

Using the width and height attributes in img tags is not recommended to reduce the rendering of an image.

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, 3 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:

2 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.

2 critical dependencies 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 our 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.

The following resources represent 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?

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).

267.6KiB of JavaScript is parsed during initial page load. Defer parsing JavaScript to reduce blocking of page rendering.

11 images (1MB) 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.

jQuery logoAs an example, with jQuery you could use a plugin dedicated to images lazyloading.

11 images (1MB) loading can be delayed on this page, representing 45% of the total weight of all your images.

This page contains 125 links

Creating and then applying an efficient link strategy to your page will enhance its SEO.

Two main link types 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 algorithms to show interest in just some of them, adding the attribute rel=nofollow to the irrelevant ones (e.g., advertisements).

Here is the sharing distribution of 125 links present in the page:

  • 63 internal links (50,40%)
  • 59 "follow" external links (47,20%)
  • 3 "nofollow" external links (2,40%)

Security 

35 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 <img> tags use an alt attribute, but 12 are empty

The alt attribute is an important criterion for SEO. Indeed, crawlers launched by search engines 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 instances:

  • When the screen reader is in use;
  • When the connection is slow;
  • When there is an error in the src attribute.

You have 35 img tags and they all have the alt attribute.

Warning, you should also note that 12 of your images contain an alt attribute, but they are empty:

  • <img alt='' height='18' src='https://resources.blogblog.com/img/icon18_wrench_allbkg.png' width='18'/>
  • <img alt='' class='icon-action' height='18' src='//img2.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/>
  • <img alt='' class='icon-action' height='18' src='//img2.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/>
  • <img alt='' class='icon-action' height='18' src='//img2.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/>

  • <img alt='' class='icon-action' height='18' src='//img2.blogblog.com/img/icon18_edit_allbkg.gif' width='18'/>
  • <img alt='' height='18' src='https://resources.blogblog.com/img/icon18_wrench_allbkg.png' width='18'/>

  • <img alt='' height='18' src='https://resources.blogblog.com/img/icon18_wrench_allbkg.png' width='18'/>
  • <img alt='' height='18' src='https://resources.blogblog.com/img/icon18_wrench_allbkg.png' width='18'/>

You can set an empty text if nothing seems appropriate for describing an image but be careful. We advise you to make sure the majority of your images contain a coherent text. Read the W3C recommendations here.
