Site loading speed: 18 services for analysis

Website loading speed is one of the most important parameters of an Internet resource. This indicator affects its ranking in the search results ranking. Sales conversion largely depends on it. It is necessary to regularly check the loading speed of the site pages using special tools and take measures to improve this indicator.

Why is it important to measure website loading speed?

Google believes that if a website page takes more than 5 seconds to load, the likelihood of a user leaving for another resource increases significantly. There is logic in this because, in this case, the visitor doubts whether it is worth exploring the Internet resource if he needs to give a quick answer. High site loading speed allows you to:

  • Attract more clients. This point is especially noticeable for mobile versions of pages. According to statistics, more and more website visitors use mobile phones to view information online. Given this circumstance, special attention should be paid to the download speed for the adaptive version.
  • Improve user experience. This moment is also directly related to attracting consumers. For example, site developers with a well-thought-out design, clear interface, and useful content believe such a resource can provide a good conversion. And this may be true, but only if all the components of the pages load fast enough.
  • Increase conversion. Conversion rates go up as the site loads faster. This is provided by “impatient” visitors who do not leave the resource after viewing the initial page.

Thus, all sites that sell services or goods must provide high page loading speed and stable operation.

How to speed up the loading of the site: 9 ways that work

Slow site loading speeds are often the reason visitors leave. Page losses due to this shortcoming can be very significant. As noted earlier, download speed is especially important for users visiting smartphone Internet resources.

Next, we will present simple recommendations to minimize the loss of customers due to slow page loading. You do not need special knowledge and experience in resource promotion to implement such advice.

Optimize HTML code and CSS, and JS files.

First of all, you should take care of the “cleanliness” of the code transmitted to the visitor’s browser to the Internet resource. With this, effective optimization of the site loading speed is possible. A long code significantly slows down the opening of pages, so you need to work on reducing the number of characters in it.

How to minify code to speed up site loading:

  • Remove unnecessary characters, tags, and markup elements from the code. Small elements can be inserted at the beginning and end of the site’s HTML code to automate page loading. This method provides PHP buffering and is quite efficient regarding download speed. It should be noted that such a solution can increase the load on RAM.
  • Collect similar CSS and JS files of the same type into groups. You can do this using free PHP applications (for example, JCH Optimize, Cloudflare, or Minify). Such programs are installed in a separate directory, after which all the HTML code files of the site are passed through them.

Remove unnecessary HTTP requests.

A huge part of the system’s capacity falls on loading elements of Internet pages. HTTP requests to JavaScript, images, CSS, and flash files greatly reduce the performance of the resource.

Reducing the number of page elements will allow you to get away from “extra” calls to the server and increase the site’s loading speed.

You can do this in several ways:

  • Merge some images into one graphic file (CSS sprite).
  • Apply built-in (Inline) pictures collected in the style sheet of the online page.
  • Collect several CSS files or scripts of the same type in one file.
  • Reduce the number of scripts and program modules used.

Put JavaScript and CSS in the right order.

Experts advise placing CSS files at the top of the page code and JavaScript at the bottom. As a result of such optimization, static information will be loaded, and only after that, dynamic graphic elements.

Animated page design elements that need more power to load will not open in the first place and give the user the wrong impression of the site from the first moment. Thus, the smooth opening of the page’s content will be ensured, and its visual appeal will increase.

Reduce the number of external scripts.

External scripts are code elements that are activated by reference to other resources. Transitions to third-party sites generate additional requests to numerous servers, slowing down page loading. You can prevent this slowdown in loading by using, to a greater extent, local scripts that are built into the structure of the original site code.

Such optimization limits the design possibilities and functionality of the resource. Still, the benefit of a high download speed more than compensates for these shortcomings.

Use the flush function.

This PHP tool clears the input buffer. The flush function makes it possible not to wait until the visitor’s server downloads all the content from the site page but to display information in parts. In this case, the window opened in front of the user will not remain empty while the data from the server is transmitted to the browser. It will gradually fill up with downloadable content. Such optimization should be recommended for sites with high traffic and complex page design.

We recommend setting the flush function at the beginning of the source code, right after the head. The content will open faster from the header, and in parallel, you can activate the loading of CSS and JavaScript elements.

Cache pages

As a result of caching, the web page’s graphics, JavaScript, CSS, and other data are stored in the visitor’s browser. Thus, when you re-enter, some of the files are quickly loaded directly from the browser, greatly speeding up the site opening process.

You can add an expired entry to the header code to connect the caching function. For caching resources created on the WordPress engine, plugins with free or partially paid functions can be used, such as W3 Total Cache, Cache Enabler, or Zen Cach.

Note that you should use caching only for sites already fully ready for work. If this feature is enabled at the resource development stage, changes made by webmasters may result in incorrect display of pages in the browser.

Use a CDN

To reduce the time of transferring the content of Internet resources to users, the Content Delivery Network was developed, which consists of data centers located in different parts of the world. Depending on the remoteness of the site visitor’s device from the CDN servers, the time spent transmitting data on the content of the site page changes.

The CDN network makes information accessible to people from all over the world.

A content delivery network is especially useful for information portals overloaded with data whose users are far from the servers’ location. Thanks to the Content Delivery Network, the loading time of foreign resources is reduced, which ensures an increase in their ranking in search results. This is because the data is loaded from a server located in the user’s country as close as possible to him.

The following CDNs (Content Delivery Networks) are popular today:

  • Google Cloud Content Delivery Network
  • Amazon Cloud Front
  • Microsoft Azure Content Delivery Network
  • Swarmify
  • Akamai
  • Limelight
  • Cloudflare
  • Rackspace Content Delivery Network.

Optimize graphics and videos.

You need to choose the right format for videos and graphics because the file parameters directly impact the speed of displaying content to site users.

Recommended formats for different web content:

  • SVG – for vector images and simple user interface details;
  • PNG – for tables and non-vector pictures;
  • JPG – for photos and other images;
  • MPEG4 – for animated elements and video files.
Optimize graphics and videos.

For videos and animations, the newly created WEBM format will be available. It supports the minimum amount of video while maintaining the same quality. But WEBM is only sometimes supported by Internet browsers (for example, there is no support on MacOS or Safari platforms).

In this regard, it can be recommended to mainly use video in WEBM format and install MPEG4 as an alternative. If sharing such formats is impossible, we recommend stopping at MPEG4.

The vector format (SVG) makes it possible to scale images without losing quality.

Image optimization steps:

  • Image scaling
  • Compress the file before uploading it to the site.

Change hosting

The most drastic way to increase the download speed can be associated with a host change. The desire to save on hosting often leads to a significant decrease in the quality of services provided, which can finally prevent the site from speeding up.

If all the activities with filling the site, plugins, and code did not bring positive results, then this is why to think about choosing another server to host the Internet resource. Working with a reliable hosting company that provides professional technical support will give your site new resources to load faster. Your audience will note changes in the work of the resource.
