1. Choose a Fast Hosting Provider

When choosing a hosting service for your Magento 2 website, prioritize speed and efficiency over pricing. Don't fall for $5 hosting that will eventually develop performance and security issues.

Use hosting services with optimized support for Magento to ensure optimal server response times. Moreover, ensure that your hosting service meets technical server requirements such as PHP version, database support, etc.

2. Upgrade to the Latest Version

New versions of Magento usually include performance improvements and bug fixes that help optimize speed. So, ensure you regularly update your Magento website to leverage these updates. If you're still on Magento 1, it's recommended you upgrade to Magento 2 for a more efficient and seamless experience.

3. Optimize Images

Large, unoptimized images significantly slow down websites. You should compress and resize your images without sacrificing quality. Modern image formats such as WebP can also help to reduce file sizes further. Additionally, improve initial page load times by implementing lazy loading to load images only when users scroll down to view them.

4. Enable Varnish Caching

Magento offers built-in caching mechanisms that can significantly boost your website's speed. Enabling caching for blocks, layouts, and collections can reduce the need to generate dynamic content repeatedly, resulting in faster page rendering.

Previous versions require users to install modules such Phoenix or Turpentine to be able to integrate Varnish to Magento. But Magento 2 provides Varnish caching by default. Varnish caching can make your website up to 300 times faster.

For Varnish caching, follow this path: Admin panel > Stores > Configuration > Advanced > System > Full Page Cache > Caching Application > Varnish Caching.

5. Use a Content Delivery Network (CDN)

Leverage the power of Content Delivery Networks (CDNs) to distribute static content, such as images, CSS, and JavaScript files, across multiple servers worldwide. By delivering content from a server nearest to the user's location, CDNs reduce latency and improve page load times.

6. Minify CSS and JavaScript

Minification removes unnecessary comments, line breaks, and whitespaces from your CSS, JavaScript, and HTML files. This results in smaller file sizes and faster downloads, improving your website's overall speed.

7. Enable Gzip Compression

Gzip compression is another effective way to speed up a Magento 2 website by compressing your website's files before sending them to the user's browser, thereby reducing the size. The smaller the data transfer size, the faster the overall speed.

8. Merge CSS and JavaScript Files

Fewer file/page requests lead to faster page loading, especially for users with slower internet connections. You can reduce the number of HTTP requests by combining multiple CSS and JavaScript files into single files. For instance, it will take more time to fetch 50 Javascript files than to fetch two files containing the 50 files merged together.

9. Lazy Load Images

Lazy loading enables Magento websites to load images only when they are about to enter the user's viewport. By implementing lazy loading, you prevent unnecessary image loading on the initial page view, thereby helping to speed up a Magento 2 website’s overall user experience.

10. Optimize Database

Regularly clean up and optimize your Magento database. Removing unnecessary data and using indexing to improve database query performance, leads to faster data retrieval.

11. Implement Full Page Caching

Full page caching stores entire pages as HTML, bypassing the need to regenerate dynamic content for every request. This significantly reduces server load and improves response times.

12. Disable Unused Modules and Extensions

Unused or inactive modules and extensions can take up space and add unnecessary weight to your Magento website. Remove or disable them to lighten the server load and increase your website's speed.

13. Use PHP Accelerators

PHP accelerators like APC or OPcache can significantly improve PHP execution times by caching compiled PHP scripts. Implementing these accelerators reduces server processing time and boosts overall website performance.

14. Limit the Use of External Resources

Third party scripts, services, and other external resources can introduce additional delays. To speed up your Magento website, host essential resources locally or choose reliable and fast external providers.

15. Optimize the Checkout Process

Streamline the checkout process to reduce cart abandonment rates. Implement a one-page checkout or a quick two-step process for faster transactions and improved user experience.

16. Implement AMP (Accelerated Mobile Pages)

With an increasing number of users browsing on mobile devices, AMP implementation is crucial for speeding up mobile page loading time. Accelerated Mobile Pages deliver a stripped-down version of your content, helping your Magento website to load faster on mobile devices.

17. Monitor Website Performance

Regularly monitor your website's performance using tools like Google PageSpeed Insights, GTmetrix, or New Relic. This will help you identify bottlenecks and address them promptly to maintain optimal speed.

18. Optimize Magento Configuration

Fine-tune Magento's configuration settings to suit your website's requirements. Optimize cache settings, session storage, and database connections.

19. Use a Fast Theme

Themes with excessive features and styles can slow down the rendering process. Choose a lightweight and well-coded Magento theme to reduce the load on your website.

20. Control Crawlers and Bots

Efficiently manage search engine crawlers and other bots to prevent them from overloading your server. Use robots.txt and crawl rate control to regulate their activity.
