How to Speed Up My Site
Speeding up your site starts with measuring where time is spent and then attacking the biggest bottlenecks. Most gains come from a small number of high-impact fixes: compress and resize images, enable browser caching, trim unnecessary code, and choose a host that matches your traffic.

Measure Before You Change
Run a test on Google PageSpeed Insights or WebPageTest to see what is slowing pages down. Focus on Core Web Vitals, especially Largest Contentful Paint, which tells you how long it takes the main content to appear. Without a baseline, you cannot tell which fixes are working.
Optimize Images
Images are often the largest files on a page. Resize them to the display size, use modern formats like WebP or AVIF, and lazy-load anything below the fold. A single uncompressed hero image can add seconds to load time.
Use Caching and a CDN
Browser caching stores static files locally so repeat visitors load faster. A content delivery network copies those files to servers closer to users, cutting round-trip time. For WordPress or similar platforms, a caching plugin can handle much of this automatically.
Trim Code and Requests
Minify CSS, JavaScript, and HTML to reduce file sizes. Remove unused scripts and defer non-critical JavaScript so the page can render without waiting for everything to download. Each external resource adds a request, and too many requests create a queue.
Check Hosting and Server Response
Slow server response time, or Time to First Byte, often points to underpowered hosting or inefficient database queries. Upgrading to a faster plan, switching to a performance-focused host, or adding an object cache can lower that number noticeably.
What to Prioritize
| Fix | Impact | Difficulty |
|---|---|---|
| Image optimization | High | Low |
| Enable caching | High | Low |
| Use a CDN | Medium–High | Medium |
| Minify code | Medium | Low |
| Upgrade hosting | Medium–High | Medium |
What Speed Gains You Can Expect
The exact improvement depends on where the biggest bottlenecks are. A site weighed down by images might drop load time in half after compression alone, while a code-heavy site may gain more from minification and deferring scripts. Re-test after each change to confirm the impact.
