WordPress Blogs on Shared Hosting
Speeding up a WordPress blog on shared hosting can be a bit tricky due to the limited resources available on shared servers.
However, there are still several ways you can optimize your blog for faster performance. Here’s a comprehensive list of strategies:
1. Choose a Lightweight Theme
Lightweight themes like Astra, GeneratePress, or Neve are designed for speed. They are clean, minimal, and optimized for performance.
Avoid bloated themes with too many built-in features you don’t need.
2. Use Caching
Install a caching plugin like W3 Total Cache or WP Super Cache. These plugins generate static HTML files for your posts, so your server doesn’t have to process PHP scripts and database queries every time a page is loaded.
Browser caching: Set up cache expiration headers to store static files like images, CSS, and JavaScript on the user’s browser for faster page loading.
3. Optimize Images
Image Compression: Use plugins like Smush or ShortPixel to automatically compress images without losing quality.
Lazy Loading: Enable lazy loading for images and videos to only load them when they are visible on the user’s screen (WP now supports native lazy loading).
Use WebP images instead of PNG or JPEG for better compression.
4. Use a Content Delivery Network (CDN)
CDN: Services like Cloudflare, StackPath, or KeyCDN can offload static content (like images, CSS, and JavaScript) to servers around the world. This reduces the distance between the server and the user, improving load times.
5. Optimize Your Database
WordPress stores a lot of data in its database. Over time, it can get bloated with post revisions, trashed items, and other unnecessary data.
Use a plugin like WP-Optimize or WP-Sweep to clean up your database and remove unnecessary items.
Consider limiting post revisions in your wp-config.php file by adding:
define( ‘WP_POST_REVISIONS’, 5 ); // Limits revisions to 5 per post
6. Use a PHP 7+ Version
Ensure your hosting provider is using PHP 7.4 or higher. WordPress performs significantly better on newer versions of PHP.
You can check your current PHP version in your hosting cPanel or ask your hosting provider to upgrade it.
7. Minify and Combine CSS/JS Files
Use plugins like Autoptimize or W3 Total Cache to minify (remove unnecessary characters from) and combine CSS and JavaScript files. This reduces file sizes and the number of requests to the server.
8. Disable Unnecessary Plugins and Scripts
Deactivate and delete plugins you no longer use.
Some plugins may load unnecessary scripts on every page (like admin scripts on the front end), which can slow down your site.
Use Plugin Organizer or similar tools to control when and where plugins load.
9. Limit External Requests
WordPress often makes external HTTP requests for things like fonts, ads, and social sharing. While some are necessary, excessive requests can slow down your site.
Use a tool like Query Monitor to check for excessive external requests and remove unnecessary ones.
10. Optimize the WordPress Heartbeat API
The Heartbeat API sends periodic requests to the server for things like auto-saves and login status checks. This can cause high CPU usage on shared hosting.
You can limit the frequency of these requests by adding this code to your functions.php:
add_filter( ‘heartbeat_send’, ‘__return_false’ ); // Completely disable Heartbeat API
// Or limit the frequency
add_filter( ‘heartbeat_send’, function( $response, $data ) {
if( isset( $data[‘action’] ) && $data[‘action’] == ‘heartbeat’ ) {
$response[‘interval’] = 60; // send heartbeat every 60 seconds
}
return $response;
}, 10, 2 );
11. Enable GZIP Compression
Enabling GZIP compression helps reduce the size of your website files (HTML, CSS, JavaScript) before they are sent to the browser, which improves load times.
Most caching plugins like W3 Total Cache support this feature.
12. Use a Faster Hosting Provider
Shared hosting has limitations that can affect performance. If you’re looking for a big speed boost, you may want to consider upgrading to a managed WordPress hosting provider or VPS.
Some of the best shared hosting for WordPress (optimized for speed) includes SiteGround, A2 Hosting, and Bluehost.
13. Reduce HTTP Requests
Too many HTTP requests can slow down page loading. Reduce requests by:
Combining CSS and JavaScript files.
Using CSS sprites for icons or small images.
Avoiding too many external embedded resources (like fonts, widgets, or ads).
14. Use a Custom or Better-Optimized Web Font
Web fonts can often add unnecessary load time. Choose fonts wisely, and consider using local or system fonts (like Arial or Helvetica) when possible.
If you use Google Fonts, only include the character sets and font weights you need.
15. Check for Malware or Security Issues
A slow WordPress site might be infected with malware, which can make requests to the server and slow things down.
Use a plugin like Wordfence or Sucuri to scan for malware and remove any threats.
16. Regularly Monitor Your Website’s Performance
Use tools like Google PageSpeed Insights, GTmetrix, or Pingdom to check your site’s performance and get detailed suggestions on how to improve it.
Monitor your site’s TTFB (Time to First Byte); if it’s high, that could indicate server-side issues that need to be addressed by your host.
Final Thoughts:
Although shared hosting presents limitations, implementing these strategies can make a noticeable improvement in your WordPress site’s speed.
The goal is to reduce the load on your server, minimize file sizes, and ensure efficient delivery of content to visitors. Consider combining these techniques for the best results!
