20 tips to speed up website loading / SEO secrets

Over time, the perception of time changes. Studies have shown that the older a person is, the slower his brain processes information. This can make it feel like time is speeding up as you age. When we are young, there is a lot of new things in the world, and our brains record every impression, which makes the sense of time more intense. With age, worries and routine tasks become more numerous, which affects the perception of time.

When creating a website, we don’t just create a resource - we think about the user. The goal is to make the site useful and convenient, as well as save time for visitors. This is an important factor: if a site is slow, users leave it faster, and behavioral factors such as bounce rate affect search engine rankings. A fast loading website is the key to successfully attracting an audience.

User path

Before a visitor reaches a website, he goes through two key stages. We need to win on each of them to attract the user's attention.

The first stage is competition for a place in search results. When a user enters a query, we must provide them with an attractive description and title to motivate them to click on our link. We discussed the question of how to correctly write a description for a search engine in one of the previous articles.

The second stage is loading the site. The user often opens several tabs and switches to those that load faster. Sometimes the difference is a fraction of a second, but for perception it is critical. Therefore, it is important that the site opens quickly. We must provide the fastest loading speed to stay ahead of the competition and provide the best user experience.

To understand how you can speed up the loading process, let's look at what happens to the site after the user enters the URL:

  • Sending a DNS query by site name.
  • Initiating a TCP connection with the server.
  • Establishing a secure connection (HTTPS).
  • Request and download of page code.
  • Parsing.
  • Loading external resources: images, styles, scripts, etc.
  • Rendering a page with full content.
  • Execution of JavaScript code with possible additional requests.

Each of these steps can be optimized. The more work we put into these steps, the faster the site will load.

How to check download speed

To check your site's loading speed, use one of the best tools - Google PageSpeed ​​Insights. To do this, simply enter the URL and click “analyze.”

You will receive detailed information about loading speed on both mobile devices and desktops. Particular attention should be paid to the points highlighted in red - their optimization will significantly speed up the site.

Next, we will look at several important aspects that will help you improve the speed of your website.

Server optimization

Server resource expansion

If your site runs on a platform with high resource requirements, such as 1C-Bitrix, it is important to ensure sufficient server capacity. The main parameters are CPU load and disk system speed. Therefore, choose reliable providers with quality equipment.

Caching

If your site is visited by the same users, setting up browser caching will help speed up loading times. Caching reduces the load on the server and reduces the amount of data that needs to be downloaded. However, you need to remember that not all data can be cached, and it is important to configure cache clearing correctly.

Database optimization

To improve database response time, it is worth optimizing queries and data schemas. Collect load statistics and analyze logs to understand which requests are slowing down your site. This will help reduce database response time.

Optimization of TCP, TLS, HTTP/2

To make large websites work faster, it is important to update network protocols such as TCP and TLS. Adaptation to HTTP/2 will also help speed up the site. Although HTTP/2 was designed to improve performance, results may vary from site to site.

Geographic location of servers

The closer the server is to the main audience, the faster the site will load. Therefore, when choosing hosting, give preference to providers with equipment located in the same region where your users are located.

Using a CDN

CDNs (Content Delivery Networks) allow files to be hosted on servers around the world, which speeds up the delivery of content to the user since the files are downloaded from the nearest server. It also helps deal with high traffic and improves the overall performance of the site.

Using Nginx and Apache

The combined use of Nginx (for the frontend) and Apache (for the backend) can significantly speed up the operation of the site, combining the power and speed of these servers.

Using a VPS or dedicated server

For large and resource-intensive sites, it is better to use a VPS or dedicated server. This will provide the necessary power to maintain stable operation under high loads.

Using external servers for heavy files

If your site uses large files such as videos, it is better to load them through third-party services (such as YouTube) to reduce server load and improve page loading speed.

How to reduce weight and speed up page loading

Image compression

Heavy images are one of the main reasons why websites load slowly. There are many ways to compress images without losing quality, including using the WebP format, which is more efficient than traditional JPEG and PNG.

Impact of CMS and code

Optimizing CMS plugins and extensions also plays a key role in website speedup. Using only the necessary plugins and eliminating unnecessary extensions will help reduce the load and increase speed. Paid CMSs are usually faster and more optimized than free ones, as they are supported by in-house specialists.

Using Gzip compression

Gzip compression helps reduce the amount of data transferred and makes pages load faster because the browser first receives the compressed files and then decompresses them.

Minification, CSS and JS

Minification removes unnecessary spaces, comments and characters from the code, which reduces its size and speeds up page loading.

Animation optimization

Excessive use of animations slows down the site. Limit the number of them to maintain download speed.

Asynchronous loading for CSS and JavaScript

Asynchronous loading allows scripts and styles to be loaded at the same time as the main content, which speeds up page load time.

Lazy loading JavaScript

Some scripts can be loaded later, after the main page content is ready, which will save resources and speed up loading.

Lazy loading

Lazy loading technology allows content to be loaded as needed, meaning parts of the page visible to the user are loaded first, and the rest is loaded as they scroll.

Which is faster: mobile version or adaptive layout

As mobile traffic takes up an increasing share, it is important to choose the best way to display your site on mobile devices. In some cases, the mobile version, although it requires additional resources, can be faster and more convenient for users than adaptive layout.

Conclusion

Although site loading speed is an important factor, do not forget about the quality of the content and its usefulness
