Page speed is no longer just about “how many seconds” a user waits. In 2026, Google measures speed through Core Web Vitals, focusing on three key areas:
- LCP (Largest Contentful Paint): How fast the main content appears.
- INP (Interaction to Next Paint): How quickly the site responds when a user clicks or taps.
- CLS (Cumulative Layout Shift): How stable the page is (does the text jump around while loading?).
If your site is slow, you aren’t just losing visitors – you are being actively pushed down in the search results. Here are the top 15 ways to modernize your site’s performance, which website maintenance services can take care of on your site.
The Big Wins: Media and Code
1. Move Beyond JPEG: Use WebP and AVIF: Old-school JPEGs are too heavy. AVIF is the 2026 gold standard, offering up to 50% better compression than JPEG while maintaining perfect quality.
2. Implement Lazy Loading (Properly): Lazy load your images and videos, but do not lazy load your “Above the Fold” content (like your hero banner). This ensures your LCP score remains high.
3. Use Brotli Compression: While Gzip was the standard for years, Brotli is the modern alternative supported by all major browsers. It compresses your HTML, CSS, and JS files much tighter than Gzip ever could.
4. Modernize Your CSS: Stop using old-school tools like YUI Compressor. Modern developers use PostCSS or Esbuild to “minify” code and remove unused CSS (PurgeCSS), significantly reducing the browser’s processing burden.
5. Host Fonts Locally: Fetching fonts from Google Fonts adds an extra external request. Download your WOFF2 font files and host them on your own server to shave off hundreds of milliseconds.
Server and Infrastructure
6. Upgrade to HTTP/3: This is the latest version of the web protocol. It is significantly faster and more reliable than HTTP/2, especially for users on mobile networks.
7. Choose High-Performance Hosting: Overcrowded shared hosting is the “silent killer” of page speed. In 2026, you should look for premium shared hosting or Managed Cloud Hosting (like WP Engine, Kinsta, or SaaS platforms like Shopify/BigCommerce setups) with dedicated CPU resources.
8. Edge Caching via a CDN: Don’t just use a CDN for images. Use Edge Caching (Cloudflare or Bunny.net) to store your entire HTML page at “the edge,” delivering your site to a user from a server physically located in their city.
9. Preconnect and DNS-Prefetch: Tell the browser which external sites (like payment gateways or tracking pixels) you are going to use before you even call them. This allows the browser to handle the “handshake” in the background.
Technical Fine-Tuning
10. Eliminate Render-Blocking Resources: Ensure your JavaScript doesn’t stop the page from “painting.” Use defer or async tags on all non-critical scripts.
11. Fix Layout Shifts (CLS): Always define the width and height of your images and ad blocks in the code. This prevents the page from “jumping” when an image finally loads.
12. Minimize Third-Party Scripts: Every “marketing pixel,” “chat widget,” or “heatmap” you add slows down your site. Perform a “script audit” once a month and delete anything you aren’t actively using.
13. Reduce Redirect Chains: Every 301 redirect adds a “round trip” to the server. Ensure your internal links point directly to the final URL, not a redirected one.
14. Optimize Database Queries: If you use WordPress, use a plugin like WP-Optimize to clean up “revisions” and bloated database tables that slow down your server’s response time (TTFB).
15. Monitor Field Data (CrUX): Don’t just trust “Lab Tests.” Use Google PageSpeed Insights to look at your Field Data. This shows you how real users, on real devices, are actually experiencing your site over the last 28 days.
Final Thoughts
Improving page speed is a continuous process, not a one-time fix. As your site grows with more content and products, you must revisit these tips to ensure your site remains lean and competitive.
