What We Optimize

There are several WP aspects we optimize to improve WordPress performance and Core Web Vitals (LCP, INP, CLS). If you don’t know how to speed up a website, rely on our WordPress speed optimization services. We optimize images for WordPress, clean “dirty” code, reduce TTFB, tune caching/CDN (WP Rocket, Cloudflare APO, Redis), and fix server/database flaws. Learn more about the aspects that the professionals of our WordPress development company optimize:

Lazy Loading Images

A vital part of WordPress image optimization and WordPress speed optimization. Loads images only when they enter the viewport, cutting bytes and improving Core Web Vitals (LCP, INP, CLS) and PageSpeed Insights. One of several methods we use to enhance UX and performance.

Render blocking resources

External CSS/JS can block rendering. We inline critical CSS, defer/async non-critical JS, preload key assets, and tame third-party scripts. This removes blocking, speeds first render, and improves CWV and PageSpeed Insights.

Server optimization

Nginx/LiteSpeed FastCGI caching, Redis Object Cache, PHP OPcache, Cloudflare APO, and smarter workers reduce TTFB and backend latency. We balance infrastructure and fix bottlenecks so response time, uptime, and CWV improve.

JS & CSS optimization

We remove unused CSS/JS, minify, code-split, and load assets conditionally. With critical CSS and defer/async, we shrink payloads and long tasks, improving INP and overall responsiveness while following WordPress Coding Standards.

Content delivery network

A WordPress CDN like Cloudflare offloads static assets, reduces TTFB, and stabilizes PageSpeed under load. We configure Cloudflare for WordPress and APO, cache keys/TTL, and edge rules as part of CDN WP speed optimization.

WordPress database optimization

We clean revisions, transients, and orphaned data, add indexes, trim autoloaded options, and tune slow queries. Regular DB optimization lowers server load, speeds queries, and supports faster TTFB and stronger CWV.

Enable compression

We enable server-side GZIP/Brotli for HTML/CSS/JS and apply WordPress image compression (WebP/AVIF with smart resize). This cuts transfer size, improves PageSpeed Insights and GTmetrix, and pairs well with CDN caching.

Cache configuration

Proper WordPress browser and server caching (Cache-Control/ETag, far-future expires, plugin rules in WP Rocket/LiteSpeed FastCGI, Cloudflare APO) reduces regeneration, lowers TTFB, and makes pages reopen instantly, boosting UX and CWV reliability.

Image optimization

We compress to WebP/AVIF, generate responsive srcset, add size attributes, and keep quality high. Combined with lazy loading, this accelerates mobile and desktop rendering, raises PageSpeed, and helps CWV.

Remove Query Strings From Static Resources

Instead of ?ver= query strings (often bypassed by CDNs), we use hashed filenames and coordinated cache-purge rules. This maximizes browser/CDN caching, lowers TTFB, and improves PageSpeed without security trade-offs.

Тesting WordPress Speed Optimization Results

We guarantee that WordPress loading speed will decrease after CDN, image compression and other optimization aspects. We are performing comprehensive performance optimizations with a focus on improving Core Web Vitals — LCP (largest contentful paint), FID (first input delay), and CLS (cumulative layout shift). In addition, specialists can optimize the whole thing — from individual functions to the admin panel. We test the work performed results using PageSpeed Grade, YSlow Grade, GTmetrix, and Google Pagespeed. Thanks to an integrated approach to WordPress speed optimization services in the USA, we can easily bring any website out of the red zone into the green one!

FAQ

What is included in your WordPress PageSpeed Optimization service?

Our PageSpeed Optimization service for WordPress includes a full audit using tools like Google PageSpeed Insights, GTmetrix, and Lighthouse. Based on the report, we optimize CSS/JS, improve Core Web Vitals (LCP, CLS, FID), configure caching, implement lazy loading, compress images, and remove render-blocking resources.

Do you optimize WordPress websites for Google PageSpeed Insights specifically?

Yes. We use Google PageSpeed Insights as a key tool in our optimization process. Our developers ensure your site passes Google’s thresholds and achieves scores of 90+ on both mobile and desktop.

How much does WordPress PageSpeed optimization cost?

The cost depends on the size and complexity of your website. After a free audit, we provide a detailed quote based on the issues found. Simple optimizations cost less, while deep code refactoring or plugin-level fixes may require more time and budget.

How do you handle CSS and JS optimization in WordPress?

We minify and combine CSS and JavaScript files, remove unused styles and scripts, and defer non-critical JS. We also implement async and lazy loading to ensure scripts don’t block page rendering.

Do you support image optimization for PageSpeed improvement?

Absolutely. We compress images, convert them to WebP, implement lazy loading, and serve them via a CDN when required. This significantly reduces loading time and improves LCP and FCP metrics.

Will you update my theme or plugins during optimization?

Only if needed. If outdated code is the cause of performance issues, we suggest updates or safe replacements. We always notify you first and create backups before making changes.

How do you perform PageSpeed testing before and after optimization?

We use GTmetrix, Lighthouse, and Google PageSpeed Insights to analyze baseline performance. After optimization, we provide before/after reports showing improvements across all major metrics including Core Web Vitals.

How long does WordPress speed optimization take?

On average, it takes 3–7 business days depending on the number of issues and the size of your website. You’ll receive a timeline and milestones after we complete the initial audit.

Can I request specific improvements based on my PageSpeed report?

Yes. If you already have a PageSpeed report and know what needs fixing — we can work on those specific areas. Our developers are flexible and can work based on your priority list.

Who will work on my WordPress PageSpeed Optimization?

Your project will be handled by experienced WP developers, QA engineers, and a project manager. We don’t outsource tasks — everything is done in-house to maintain high quality.

Do you provide ongoing support after optimization?

Yes. We offer monthly maintenance and monitoring to keep your speed scores high. This includes plugin updates, security patches, and periodic performance checks.

How do you communicate progress during optimization?

You’ll be assigned a dedicated manager who provides regular updates via email or chat. You’ll also get access to reports, checklists, and documentation.
