Let‘s get started, shall we?
Why You Absolutely Must Prioritize Your Website‘s Speed
Let‘s first better understand why fast site speed should be priority one for your WordPress site instead of an afterthought.
As a website performance strategist who has optimized over 100 WordPress sites in my career, I‘ve seen firsthand how speed impacts key metrics across traffic, rankings and revenue.
Here‘s compelling data that re-emphasizes why load time matters:
- 53% of users abandon sites taking over 3 seconds to load (Source: Google)
- Every 100 millisecond delay drops conversion rates by 1% (Source: Admiral)
- Pages taking over 4 seconds to load suffer a 63% bounce rate (Source: Cloudflare)
- Faster sites achieve over 30% higher conversion rates (Source: Cloudflare)
It‘s clear that a slow WordPress site leads to unhappy bounce-prone visitors who won‘t convert on your calls-to-action. Moreover, site speed is a ranking factor for Google among other search engines. Faster sites can achieve higher organic visibility and traffic by default.
By optimizing your website performance, you‘ll be able to handle more visitors without slowing down thanks to efficiency gains across page loads, database queries and server resource usage.
Now let‘s explore how to accurately measure your current website speed using the right tools and methodologies. This will serve as an essential baseline before applying improvements.
Step 1: How to Test Your WordPress Site‘s Speed
Before optimizing site speed, it‘s vital we objectively measure current performance across these vital metrics:
- Server response time: The time taken for the initial connection to complete after a request is made
- Time to first byte (TTFB): Latency until the first byte of page HTML is received
- DOM load time: Duration taken to fully parse the document object model
- Page load time: Total time taken for entire page including CSS, JavaScript and images to display without a spinner
- Individual resource load times: Time taken for hero images, third-party tools (analytics, social sharing buttons) and other above-the-fold elements to load
I recommend leveraging a combination of free tools like Lighthouse, WebPageTest, SpeedLab and commercial monitoring solutions like Pingdom for comprehensive analysis.
Lighthouse integrates nicely within Chrome Developer Tools delivering lab data on performance opportunities. However, actual visitor experiences vary across device capabilities and network connections.
This is why I suggest WebPageTest next to better understand field performance by testing from real-world locations and connections. Configure first view and repeat view tests to analyze caching gains.
For device-specific data, BrowserStack‘s SpeedLab tool lets you test site speed across 2000+ browser and device combinations on real iOS, Android and Windows devices hosted in a live cloud infrastructure. The free report offers optimization recommendations tailored to WordPress.
Once you have comprehensive page load speed data, identify any glaring issues failing reasonable performance benchmarks:
- Server response under 200ms
- TTFB between 100-500ms
- Page load under 2 seconds
- Hero image load under 1 second
Repeat this speed testing process monthly tracking how optimizations further improve metrics over time. For large traffic websites, consider even more frequent profiling.
This real data will serve as an essential baseline for measuring the success of various website optimizations we‘re about to implement.
Now let‘s explore actionable ways to achieve dramatically faster WordPress performance.
Step 2: Resize and Optimize Your Images
Image elements often account for over 50% of page weight and load times for content-heavy websites. Optimizing your visual assets results in massive performance gains.
You can manually tweak image dimensions and compression levels across tools like Photoshop. However, I recommend enabling automated image optimization instead for 10x productivity.
Install a plugin like ShortPixel, EWWW or Smush to seamlessly optimize images on your WordPress site. These intelligently compress images by removing EXIF profile data, optimizing metadata and trimming unnecessary bytes.
Configure your media library to also generate multiple thumbnails of varying dimensions instead of forcing every visitor to load ginormous 2000 x 4000 hero banner images! Output responsive breakpoints like desktop, tablet and mobile sizes as needed per page layout.
Furthermore, implement lazy loading of below-the-fold images. This prevents downloading unnecessary assets not seen on the user‘s initial viewport. Images only load as visitors scroll past placeholders revealing additional content.
Combined these techniques can easily reduce image payload sizes by up to 80% with limited perceived quality change due to selective compression. Given images tend to dominate page weight, so do the performance gains from properly resizing and optimizing them!
Step 3: Boost Speeds with Caching
Since WordPress dynamically builds page HTML on every request, repeated lookups get expensive. Instead, we can cache fully rendered pages and serve those static copies to repeat visitors. This skips resource-intensive DB queries and PHP processing associated with page building.
I recommend enabling a well-optimized caching plugin like WP Rocket or W3 Total Cache. They automatically handle multiple tiers of caching:
- Page caching stores rendered page HTML
- Object caching saves processed DB queries
- Database caching minimizes expensive SQL queries
- Browser caching facilitates reuse of static assets
The plugins also invalidate and purge caches upon content changes so visitors never see stale copies.
You can take caching even further with a Content Delivery Network (CDN). These distributed proxy networks cache static assets in data centers closer to visitors for up to 10x faster access. Top CDNs like Cloudflare offer generous free tiers to get started.
Intelligently configuring cache lifetimes between page, object, database and CDN caching layers will minimize server strain and keep repeated visitors snappy through cached experiences. This allows supporting higher traffic without expensive infrastructure upgrades.
Step 4: Prune Inefficient Plugins
Too many plugins – especially outdated or subpar coded ones – bloat request overhead and slow down WordPress sites. I advise auditing your plugins list every quarter and pruning inefficient tools.
Identify unused plugins without recent activity and remove them. If you used a plugin previously just for a one-time migration/cleanup, take it off upon completing that task. Archive (instead of delete) just in case you need to restore the configuration.
For active plugins, see if you can consolidate tools with overlapping capabilities for simplicity. For example, contact form plugins often bundle popup, slide-in capabilities that dedicated tools may offer. Assess expected usage before stacking on more plugins.
In necessary plugins, disable any extraneous optional modules outside the core feature set you actually rely on. For example, if you use Yoast SEO primarily for XML sitemaps, disable the on-page content analysis component consuming resources. Slim down to just the must-have functionality.
Weigh building deeply customized experiences natively on WordPress vs piling on bulky premium plugins. If budget permits, consult capable WordPress developers to extend functionality efficiently without bloat.
Step 5: Scale Up Infrastructure
Even after fully optimizing software, you may outgrow your hosting infrastructure‘s capacity slowing down site performance.
Instead of remaining stuck on laggy, overloaded shared hosting plans, consider upgrading to VPS, managed cloud hosting or dedicated servers to unlock more computing resources.
Hosting providers like Kinsta and Pagely offer optimized WordPress infrastructure without server admin overhead. For larger businesses, consult specialized managed hosting providers to plan and deploy robust containerized infrastructure with auto-scaling capabilities.
The additional headroom and optimized server configuration dramatically accelerates WordPress speeds despite growing traffic volumes. If budgets allow, plan smart infrastructure growth aligned to current and projected performance needs.
Step 6: Enable GZIP Compression
GZIP shrinks payload sizes by 30-70% by eliminating duplicate strings and reducing redundancy. Since less data gets transferred, we directly speed up page loading.
Modern browsers transparently handle compressed content via decoders and gracefully fall back for others.
To enable GZIP compression on your WordPress server:
- Connect via SFTP/SSH
- Add the following .htaccess rule to your WordPress root directory:
<IfModule mod_deflate.c>
# Enable compression
SetOutputFilter DEFLATE
# Set compression level
DeflateCompressionLevel 5
# Specify compressed content types
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript application/x-javascript application/json
</IfModule>- Restart Apache/Nginx service
Next, verify compression gets applied via PageSpeed Insights. Target enabling GZIP compression for HTML, JavaScript, CSS, JSON and fonts to start with for maximum gains. For SVG, PDF and images, balanced lossless + lossy algorithms like Zopfli, Brotli and WebP outperform GZIP.
Step 7: Preload Key Requests
Even with code splitting, we can directly speed up rendering by preloading key requests in parallel.
Hero images, critical CSS and necessary 3rd party tools often delay initial visualize. The browser has to first download, process and inject these assets before safely showing page content without unwanted Cumulative Layout Shift.
We can cut this out by preloading vital assets very early in the header:
<!-- Preconnect fallback origin -->
<link rel="preconnect" href="https://cdn.example.com">
<!-- Prefetch baseline code -->
<link rel="prefetch" href="script.js">
<!-- Preload hero image -->
<link rel="preload" as="image" type="image/webp" imagesrcset="hero-lg.webp" href="hero.jpg">
<!-- Preload critical CSS -->
<link rel="preload" href="critical.css" as="style">
<!-- Preload web font -->
<link rel="preload" href="font.woff2" as="font" type="font/woff2" crossorigin>This powerful yet underused optimization circumvents render-blocking behavior achieving quicker first paint. Try preloading hero content, web fonts and critical framework/libraries like React/Angular for your WordPress install.
Step 8: Monitor and Optimize Database Performance
An expanding content library and large visitor volumes strain database infrastructure slowing down read/write speeds.
Regularly optimize database tables by removing transient redundancy and fixing index inefficiencies. Schedule re-indexing during off hours to prevent locking/timeout issues.
Audit SQL queries executed during pageloads – are repetitive queries fetching identical data? Configure database caching to return persisted query results instead of running fresh lookups.
Scale out your database infrastructure by deploying managed solutions like Amazon RDS, Azure Database for MySQL allowing near-infinite scaling. Set up read replicas to divert analytical vs transactional workloads.
By monitoring database load metrics and optimizing data access patterns, you prevent the data layer from strangling WordPress performance.
