Website speed is no longer an optional feature; it’s a fundamental and vital requirement for online success. Today’s users expect web pages to load in under 3 seconds, and if your site fails to meet this expectation, the likelihood of visitors quickly leaving is very high. Furthermore, Google has officially announced that website speed is one of the most important factors in its page ranking algorithm, and faster sites have a better chance of appearing in top search results.
In this comprehensive and practical guide, we will show you how to increase your website speed several times over by making simple and precise adjustments to your hosting, without the need for complex technical knowledge, professional coding, or the use of specialized tools. These methods are applicable and effective for all levels of users, from beginners to professionals. Before anything else, it’s best to learn more about web hosting by reading the content What is Hosting?.
Why is Increasing Website Speed Important?
Website loading speed is one of the most critical factors for success online. Today’s users have become very impatient, and if your site doesn’t load within a few seconds, they will easily leave it. According to statistics, more than 70 percent of users will not wait if a page takes more than 3 seconds to load and will exit the site.
On the other hand, website speed has a direct impact on the Conversion Rate. The faster the speed, the more likely a visitor is to become a customer. This is especially important for online stores and e-commerce sites.
Also, a fast website provides a much better user experience. Users are more satisfied with interacting with a site that loads smoothly and without delay. This satisfaction leads to increased brand trust and repeat visits.
Finally, search engines like Google also consider website speed as a key ranking factor. The Core Web Vitals algorithm specifically focuses on metrics such as loading time, page stability, and user interaction. Therefore, slow websites usually rank lower in search results.
You can use the tools introduced in the content Introduction to Website Speed Test Tools to check your website’s speed.
1. Choosing a Suitable and Scalable Hosting Plan
If you’re just starting out, shared hosting might be sufficient. But as your site grows, you should move to more powerful options. Shared hosting is suitable for small and new websites, but if your site has high traffic or is an online store, be sure to migrate to a VPS.
Features to look for in a suitable hosting plan:
- At least 2 GB of RAM (recommended for WordPress)
- Powerful CPU with dedicated or semi-dedicated resources
- Using SSD or NVMe drives
- Support for LiteSpeed or Nginx for better performance
- Ability to upgrade to VPS or dedicated server if needed
2. Enabling GZIP or Brotli Compression
Compressing static files such as HTML, CSS, and JavaScript reduces the amount of data sent from the server to the user’s browser. This reduction in data volume significantly speeds up page loading and improves website speed. As a result, you will have a better user experience and reduced bandwidth consumption.
To enable GZIP compression in the cPanel hosting control panel, simply log in to the panel and go to the Optimize Website section. Then select the Compress All Content option and save the changes to enable compression.
Important Note: Some servers, in addition to GZIP, also support the Brotli compression algorithm, which performs better and can compress data with less volume and faster speed. If possible, it is recommended to use Brotli to maximize website speed.
۳. Setting Up Server-Side Caching
Caching is one of the most important speed optimization techniques that eliminates the need to reprocess website-generated content each time users request it by storing it in memory. This reduces the load on the server and significantly increases page loading speed.
The method of setting up caching depends on your web server type. If you are using the LiteSpeed web server, the best option is to use the powerful LiteSpeed Cache plugin, which is specifically optimized for this server and offers very high performance. On the Apache web server, plugins like W3 Total Cache and WP Super Cache are popular and efficient caching options that can significantly improve site speed. Also, on the Nginx web server, you need to manually configure the cache in the configuration files, which requires more technical knowledge.
In general, hosts that offer the LiteSpeed web server have the best performance in caching, and it is recommended to use this type of hosting if possible.
4. Upgrade PHP Version to the Latest Stable Version
PHP versions are constantly updated, and each new version offers significant performance improvements in processing speed in addition to improved security. For example, newer versions of PHP can increase the speed of executing site code by more than 20%, which significantly improves the overall site speed. Also, new versions include support for more advanced functions and features and increase your site’s security against vulnerabilities.
To upgrade the PHP version, simply log in to your hosting control panel (such as cPanel) and go to the Select PHP Version section. In this section, you can view different PHP versions and select and activate a stable and new version such as PHP 8.1 or PHP 8.2. Before changing the version, make sure that your site’s theme and plugins are compatible with the new PHP version to avoid any problems with the site’s performance.
5. Enabling Keep-Alive for Faster Connections
The Keep-Alive protocol allows users’ browsers to receive multiple files using a single HTTP connection. This feature reduces the number of new connections between the browser and the server, and consequently, significantly increases the site’s loading speed.
To enable Keep-Alive on the Apache web server, simply add the following code to your site’s .htaccess file:
Header set Connection keep-alive
If you are using the Nginx web server, you must set the keepalive_timeout value in the server configuration file as follows:
keepalive_timeout 65;
If you do not have access to the configuration files or are not familiar with server settings, the best course of action is to ask your hosting support team to enable this feature for you so that your site speed improves without any issues.
6. Optimize External Requests
One of the hidden but influential factors in reducing site speed is the number and size of requests sent to external resources. These requests may be used to load fonts, advertisements, JavaScript files, or even statistical and analytical services. The slower or less accessible these resources are, the more your overall site loading speed is affected.
To optimize this section, you should reduce your site’s dependence on external domains as much as possible. Loading large files from unreliable or uncached sources can cause significant delays in page loading. Instead of using external fonts (such as Google Fonts), it is recommended to use Local Fonts so that they do not need to be loaded from other servers.
Additionally, you can block unnecessary or intrusive domains and prevent useless requests by using DNS settings or a firewall in your hosting panel.
Every external request is a risk of slowing down your site. Use it only when necessary and from trusted sources.
7. Smart Use of CDN
One of the most effective ways to increase website loading speed in different geographical locations is to use a Content Delivery Network (CDN). A CDN allows your website content — including images, static files, and even some dynamic requests — to be loaded from the server closest to the user’s location. This reduces the physical distance between the user and the server, resulting in reduced latency and a significant increase in website speed.
Another advantage of a CDN is reducing the load on the main server. By transferring the content load to the CDN’s network servers, the main server’s resources are freed up, and the overall performance of the site is improved.
Some Popular and Reliable CDNs:
- Cloudflare: A free, powerful, and very popular option with additional security and optimization features.
- BunnyCDN: One of the fastest and lowest-latency CDNs on the market, with affordable pricing.
- Some hosting companies also offer internal or dedicated CDNs; be sure to ask your host’s support about it.
Important note: Using a CDN should be done in conjunction with internal hosting optimization, not as a replacement for it. Combining these two methods will provide the best results for your site’s speed and stability.
Checking Server Logs and Resource Usage
If you experience a sudden slowdown or performance degradation of your site, it is possible that a specific plugin or code is causing increased resource consumption or an error. In such cases, carefully reviewing the server logs is one of the fastest and most effective ways to find the source of the problem.
To get started, log in to your hosting control panel (usually cPanel) and go to Metrics > Resource Usage. In this section, you can see the amount of CPU, RAM, and other server resources consumed and identify times when consumption was excessive.
Also, checking the Error Logs section can provide very useful information about internal site errors. Common errors such as 500 Internal Server Error often indicate a problem with one of the site’s scripts or plugins.
Key items to check:
- Unusual RAM or CPU usage
- Plugins that take a long time to load
- Scripts that cause server errors
By accurately identifying these issues and fixing them, you can restore the site’s performance to normal and prevent annoying slowdowns.
9. Choosing the right geographic location for the server
One of the lesser-known but highly influential factors in website speed is the physical location of the server hosting your site. The geographical distance between the user and the server directly affects the response speed. The shorter this distance, the faster the information is transmitted, and the faster the site will load.
If most of your audience or customers are within Iran, it is recommended to use domestic hosting with data centers located in Iran. This will significantly reduce latency and improve user experience. Conversely, if your site has international visitors or is designed for the global market, it is better to host the server in Europe or the United States to ensure optimal performance for users outside of Iran as well.
Shorter Geographical Distance = Faster Response Time (Lower Latency)
