Service overview
What Is Page Speed Optimization?
Page speed optimization is the process of reducing the time, data transfer, browser work, server processing, and visual disruption required to display and use a website.
It can involve improvements across several technical layers. Origin server work may cover hosting, server response, application processing, database queries, API responses, and redirects. Network and delivery work may cover CDN, compression, HTTP caching, browser caching, DNS, TLS, and geographic delivery. Frontend work may cover HTML, CSS, JavaScript, images, fonts, components, rendering, and hydration. Third-party services may include analytics, advertising, consent tools, chat systems, video, booking, payment, and embedded content.
A complete optimization project identifies which layer is causing the delay before changing the website.
Service overview
What Are Core Web Vitals?
Core Web Vitals are Google’s current field-based metrics for loading performance, responsiveness, and visual stability. The current metrics and recommended “good” thresholds are Largest Contentful Paint at 2.5 seconds or less, Interaction to Next Paint at 200 milliseconds or less, and Cumulative Layout Shift at 0.1 or less. These thresholds are evaluated at the 75th percentile, meaning that the target should be met for at least 75% of measured page visits, with mobile and desktop considered separately.
LCP measures how quickly the main visible content is rendered. The LCP element may be a hero image, banner, large heading, content block, product image, background image, or video poster.
INP measures the responsiveness of a page across user interactions such as clicks, taps, keyboard input, menu opening, filter selection, form interaction, and product selection. INP includes input delay, event-processing time, and the delay before the browser displays the next visual response.
CLS measures unexpected movement of visible page content. Common causes include images without dimensions, advertisements without reserved space, embeds and iframes, dynamically inserted content, font changes, banners, and notices. Google recommends reserving predictable space for images and similar elements to reduce layout movement.

Service components
What Is Included in Page Speed Optimization?
Performance Discovery and Business Priorities
This helps prioritize pages that matter to users and the business.
- Website platform, hosting, traffic, devices, countries, and important landing pages
- Revenue pages, lead forms, booking and ecommerce journeys, advertising landers
- Recent website changes and known performance problems
Page Template Inventory
Performance problems often differ significantly between templates.
- Homepage, service, product, category, blog, location, and landing pages
- Search results, cart, checkout, login, application pages, and account dashboards
Field and Laboratory Data Review
Field data reflects real visitors, while laboratory tools provide controlled diagnostics that can help reproduce and investigate problems.
- Search Console Core Web Vitals, CrUX, PageSpeed Insights, and Lighthouse
- Browser performance tools, RUM, analytics, CDN analytics, and hosting monitoring
Mobile and Desktop Comparison
Mobile performance problems should not be assumed from desktop results.
- Device processing power, screen size, mobile navigation, and network speed
- Responsive images, mobile-only widgets, sticky elements, and touch interaction
Core Web Vitals Audit
The audit separates good, needs improvement, poor, insufficient data, lab-only findings, and field-confirmed findings.
- LCP, INP, CLS at URL-level and origin-level results
- Mobile and desktop groups, affected templates, page-volume impact, and business priority
Largest Contentful Paint Analysis
Google’s LCP guidance recommends breaking the metric into its contributing delays rather than treating it as one unexplained number.
- Time to First Byte, resource discovery delay, resource loading duration, and element render delay
- Server response, late image discovery, JavaScript rendering, CSS, resource size, hydration, and third parties
Interaction to Next Paint Analysis
The analysis may identify main-thread blocking, long JavaScript tasks, expensive event handlers, rendering delays, layout recalculation, large DOM structures, third-party script work, and hydration delays.
- Navigation menus, search, filters, product variants, and add to cart
- Forms, accordions, tabs, calculators, booking widgets, and account controls
Cumulative Layout Shift Analysis
The analysis distinguishes the element that moved from the element that caused the movement.
- Missing image dimensions, responsive images, font replacement, and cookie notices
- Promotional banners, ads, embeds, lazy-loaded content, sticky headers, and client-side components
First Contentful Paint Review
FCP supports diagnostics but is not one of the three current Core Web Vitals.
- Slow server response, render-blocking styles and scripts, and large HTML
- Font dependencies, redirects, client-side rendering, and consent tools
Time to First Byte Analysis
A frontend-only change cannot correct every TTFB problem.
- Slow hosting, server location, application processing, and database queries
- Cold serverless functions, middleware, authentication, APIs, redirects, and cache misses
Server and Hosting Review
Recommendations are adapted to the hosting platform.
- Server resources, CPU, memory, geographic location, and application runtime
- PHP or Node.js runtime, serverless cold starts, web-server settings, database, and caching
Database Performance Review
Especially relevant for WordPress, WooCommerce, ecommerce, marketplaces, booking systems, and custom applications.
- Slow queries, repeated queries, missing indexes, large option tables, and autoloaded data
- Unnecessary joins, product filtering, search queries, plugin queries, and connections
API and Backend Dependency Review
I review whether APIs should be cached, parallelized, deferred, combined, preloaded, moved server-side, removed from the critical path, or given fallback behaviour.
- Product data, availability, prices, reviews, and user information
- Search results, recommendations, external services, CRM data, and booking information
Rendering Strategy Review
The strategy affects initial HTML, LCP, JavaScript requirements, hydration, caching, crawling, server cost, and data freshness.
- Static HTML, server-side rendering, static generation, and incremental regeneration
- Client-side rendering, streaming, and hybrid rendering
Next.js Performance Optimization
Client components are used only where browser interactivity is required.
- App Router or Pages Router, server and client components, and route rendering
- Static or dynamic rendering, images, fonts, scripts, data fetching, Suspense, middleware, bundles, hydration, and cache behaviour
React and JavaScript Application Optimization
The objective is to reduce browser work without breaking application behaviour.
- Bundle size, route splitting, component rendering, hydration, and state management
- Unnecessary rerenders, event handlers, large dependency imports, client-side fetching, DOM size, and memory use
WordPress Performance Optimization
Plugins are not installed simply because they advertise performance optimization.
- Theme, page builder, plugins, database, PHP, object cache, and page cache
- Cron jobs, autoloaded options, external scripts, fonts, images, WooCommerce sessions, Admin AJAX, and REST API activity
WooCommerce Performance Optimization
Cart, account, and checkout pages require different caching rules from public product content.
- Product queries, category pages, cart fragments, sessions, checkout, and customer accounts
- Product filters, inventory, dynamic prices, database tables, payment scripts, analytics, and marketing pixels
JavaScript Inventory
Scripts may be classified as essential, important but delayable, page-specific, conditional, unused, replaceable, or removable.
- Size, execution time, main-thread impact, and loading priority
- Page coverage, business purpose, ownership, and third-party origin
JavaScript Bundle Reduction
Bundle reduction should be validated through actual build output.
- Code splitting, tree shaking, dynamic imports, and dependency replacement
- Partial imports, removing unused libraries, route- or component-level loading, reducing polyfills, and avoiding duplicate packages
Long Task Optimization
Possible improvements include breaking work into smaller tasks, yielding to the browser, deferring non-critical work, moving suitable processing to workers, and reducing the work performed.
- Script evaluation, large loops, heavy event handlers, and DOM processing
- JSON parsing, third-party execution, synchronous operations, and expensive state changes
Event Handler Optimization
Improvements may include reducing callback work, avoiding unnecessary state updates, debouncing, throttling, passive listeners, event delegation, separating visual updates, and removing duplicate listeners.
- Clicks, key input, scroll, resize, and touch events
- Form fields, menus, filters, dragging, and search
Third-Party Script Optimization
Each script is evaluated by business value, loading cost, execution cost, page coverage, consent dependency, and alternative implementation.
- Analytics, advertising, chat, heatmaps, consent, and reviews
- Social widgets, video, A/B testing, CRM, booking, payment, and personalization
Google Tag Manager Performance Review
GTM does not automatically make third-party scripts lightweight.
- Duplicate tags, sitewide tags that should be conditional, and broad triggers
- Custom HTML, large scripts, repeated events, old advertising tags, unused variables, and consent behaviour
CSS Inventory and Reduction
Possible improvements include removing unused styles, splitting CSS by route, reducing framework output, loading page-specific styles, simplifying selectors, and minifying production files.
- Stylesheet size, unused CSS, framework output, and page-builder CSS
- Duplicate rules, component styles, third-party CSS, media queries, and critical styles
Critical CSS and Render-Blocking Resources
Critical CSS should not become an unmaintainable manually copied block.
- Critical CSS, deferred non-critical CSS, and route-level styles
- Inline essential styles, reduced stylesheet requests, and prioritized font styles
Image Inventory and Optimization
Large images are prioritized according to their page position and business importance.
- File format, file size, display dimensions, intrinsic dimensions, and responsive variants
- Compression, loading priority, lazy loading, CDN delivery, decorative images, and background images
Modern Image Formats
Modern formats do not replace correct image sizing. Fallback behaviour, image quality, transparency, browser support, and processing cost are considered.
- WebP and AVIF conversion where supported by the website and delivery system
Responsive Image Delivery
Visitors should not download a desktop-size image for a small mobile container without a justified reason.
- srcset, sizes, device-specific widths, and CMS-generated sizes
- Product thumbnails, hero variants, mobile crops, and high-density displays
LCP Image Prioritization
The implementation depends on how the image is rendered.
- Direct HTML discovery, high fetch priority, preloading, and removal from lazy loading
- Correct responsive source, smaller file size, faster CDN delivery, and reduced render delay
Lazy Loading Review
Above-the-fold LCP content should not normally be delayed through generic lazy-loading rules.
- Images below the fold, hero images, iframes, videos, and embeds
- Components, product recommendations, and related content
Font Performance Optimization
Unnecessary font families and weights are removed where possible.
- Font families, weights, file formats, character sets, and external font providers
- Local hosting, preloading, fallback fonts, font-display, variable fonts, and layout shifts
Layout Stability Controls
This may use width and height attributes, aspect ratios, minimum heights, skeleton layouts, stable placeholders, and predictable component dimensions.
- Images, videos, embeds, iframes, advertisements, and forms
- Banners, cookie notices, recommendations, and dynamic components
Navigation and Header Stability
I test header behaviour throughout loading and interaction.
- Fonts change, logos load late, sticky behaviour activates, and banners appear
- Menus hydrate, user-account content loads, and consent notices change height
Cookie and Consent Platform Performance
The implementation must still respect the customer’s approved consent requirements.
- Impact on LCP, INP, CLS, script loading, main-thread work, and visual overlays
- Whether the platform loads too much code, blocks rendering, creates layout shifts, or initializes tags inefficiently
Video and Embed Optimization
Possible improvements include facades, poster images, click-to-load behaviour, lazy loading, reserved space, conditional loading, simplified embeds, and linking externally where appropriate.
- YouTube, Vimeo, maps, social embeds, and reviews
- Booking widgets, calendars, dashboards, and external forms
HTML and DOM Optimization
An unnecessarily large and complex DOM can increase style, layout, rendering, and interaction work.
- HTML size, DOM depth, number of elements, and repeated wrappers
- Hidden components, page-builder output, navigation complexity, large tables, and repeated cards
Compression
Compression reduces transfer size but does not replace removing unnecessary resources.
- HTML, CSS, JavaScript, JSON, SVG, API responses, and text files
- Brotli, Gzip, CDN compression, and origin compression
Browser Caching
Frequently changing HTML requires different rules from versioned static assets.
- Images, fonts, CSS, JavaScript, documents, and static application assets
- Cache-Control, expiration, immutable assets, file versioning, and revalidation
CDN Configuration
Possible environments include Cloudflare, hosting-platform CDN, ecommerce CDN, application platform, or a customer-approved provider.
- Static asset delivery, geographic latency, cache hit ratio, and origin load
- Image delivery, compression, TLS, and traffic peaks
Cloudflare Performance Configuration
This can be coordinated with the dedicated Cloudflare Setup and Optimization service.
- Proxy review, Cache Rules, browser cache, edge cache, and compression
- Images, redirects, origin response, cache exclusions, and cache status validation
Page and Object Caching
Personalized and transaction-related content requires careful exclusion.
- Full-page cache, fragment cache, object cache, and database query cache
- API cache, build cache, server-rendered output, and static generation
Redirect and Request Reduction
Every unnecessary request or redirect adds network work.
- HTTP-to-HTTPS redirects, www normalization, trailing slashes, and asset redirects
- Image redirects, tracking redirects, old CDN URLs, internal links through redirects, and redirect chains
Resource Hint Review
Preloading too many resources can compete with genuinely important requests.
- Preload, preconnect, DNS prefetch, module preload, and fetch priority applied selectively
Service Worker and Browser Cache Review
Incorrect service-worker caching can preserve broken or outdated website versions.
- Cached assets, update strategy, stale files, offline behaviour, and cache size
- Runtime caching, navigation requests, versioning, and error handling
Performance Budget Definition
Budgets may vary by page template.
- JavaScript, CSS, images, fonts, third-party scripts, total page weight, and requests
- LCP, INP, CLS, and server response
Performance Monitoring Setup
Google’s web-vitals library can collect LCP, INP, and CLS directly for custom field measurement.
- Search Console, CrUX, PageSpeed Insights API, and Lighthouse automation
- Real User Monitoring, web-vitals library, hosting monitoring, Cloudflare analytics, and custom dashboards
PageSpeed Insights API Integration
Automated testing should use a representative URL set rather than every URL without prioritization.
- Scheduled checks, template samples, mobile and desktop results, and historical storage
- Alerts, dashboard output, and regression comparison
Performance Regression Testing
A website can become slow again after a successful optimization project when future changes are not monitored.
- New features, tags, images, design changes, plugins, and framework upgrades
- Advertising, consent systems, CMS changes, and deployments
Before-and-After Validation
Lab improvements may appear immediately, while field datasets require new real-user visits before their reporting reflects the change.
- LCP, INP, CLS, FCP, TTFB, Lighthouse score, resource size, and request count
- JavaScript execution, cache status, important interactions, and conversion functionality
Functional Quality Assurance
A faster page that loses important functionality is not a successful optimization.
- Navigation, forms, search, filters, product variants, cart, checkout, and payment
- Booking, login, account, tracking, consent, videos, embedded systems, and APIs
SEO Quality Assurance
I verify that performance changes do not negatively affect crawlability and search controls.
- Crawlable HTML, canonical tags, metadata, structured data, and internal links
- Hreflang, robots directives, XML sitemaps, status codes, image indexing, content visibility, and JavaScript rendering
Implementation Documentation
I document findings, changes, results, limitations, and next steps.
- Initial findings, affected templates, bottlenecks, implemented changes, and configuration changes
- Removed scripts, cache rules, performance budgets, test results, known limitations, monitoring, and future recommendations
Developer-Ready Recommendations
Recommendations are written as implementation tasks rather than generic audit statements.
- Problem, evidence, affected pages, technical cause, and recommended implementation
- Priority, dependencies, acceptance criteria, test procedure, and expected risk
Post-Launch Monitoring
Unexpected changes are investigated against the production release.
- Core Web Vitals, page errors, forms, transactions, bookings, and cache behaviour
- Server response, third-party scripts, mobile output, search crawling, analytics, and user journeys
Ongoing Performance Maintenance
Ongoing support keeps performance stable as the website evolves.
- Monthly template testing, new-release review, Core Web Vitals monitoring, and third-party tag review
- Image checks, JavaScript bundle checks, plugin review, hosting analysis, cache validation, regression alerts, and reporting

Specialist
Why Work With Me for Page Speed Optimization?
I combine performance optimization with technical SEO, website development, Next.js, WordPress, analytics, tracking, Cloudflare, website migrations, AEO, GEO, and conversion measurement.
This allows me to evaluate both: Why the website is slow Which changes are safe for its business and search requirements
I review: Which page templates affect the most users Which resources delay important content Which JavaScript blocks interactions Which elements create layout shifts Whether the server or frontend is the main bottleneck Whether caching is safe for each page type Which third-party scripts are commercially necessary Whether a laboratory result reflects field performance Whether optimization changes affect crawling or tracking How future releases should be controlled
Rather than sending only a PageSpeed screenshot, I document: The technical cause The affected pages The user impact The recommended fix The implementation requirements The acceptance criteria The test method The measured result The remaining limitation The maintenance responsibility
I can support the process from performance diagnostics and prioritization through implementation, testing, deployment, monitoring, and long-term performance governance.
Common questions
Frequently asked questions
Page speed optimization improves how quickly a website responds, loads its important content, becomes interactive, and maintains a stable visual layout.
The current Core Web Vitals are Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. The recommended good thresholds are LCP at 2.5 seconds or less, INP at 200 milliseconds or less, and CLS at 0.1 or less.
No. A score of 100 is not required for a useful, successful, or search-visible website. The goal is to improve real-user experience and important website journeys without breaking business functionality.
The Lighthouse score is based on a controlled laboratory simulation. PageSpeed Insights may also display available field information from CrUX, which reflects eligible real-user experiences.
Results may vary because of server response, network conditions, test environment, third-party scripts, cache state, dynamic content, advertising, API responses, CPU simulation, and temporary platform behaviour. Several tests and field information are more useful than one isolated score.
Mobile testing commonly uses more limited processing and network conditions. The mobile version may also load different navigation, images, components, sticky buttons, advertising, widgets, and responsive layouts.
No. The achievable result depends on platform, hosting, website design, required functionality, third-party services, advertising, booking systems, ecommerce, consent tools, and content. I focus on meaningful, sustainable improvements rather than guaranteeing a test score.
Google recommends good Core Web Vitals as part of a strong page experience, but explains that there is no single page-experience signal and good scores do not guarantee top rankings.
A faster and more responsive experience may reduce friction, but conversion results also depend on offer, trust, content, pricing, design, audience, traffic quality, and sales process. Conversion improvements cannot be guaranteed from speed work alone.
Yes. WordPress optimization may include plugins, theme, page builder, PHP, database, images, fonts, scripts, caching, CDN, and hosting.
Yes. WooCommerce work may include product templates, category queries, cart, checkout, sessions, database, payment scripts, marketing tags, and cache exclusions.
Yes. Next.js optimization may include server and client components, rendering strategy, image delivery, fonts, data fetching, bundles, hydration, caching, middleware, and third-party scripts.
Yes. I can review bundle size, rendering, hydration, change detection, event handling, route loading, DOM complexity, and API dependencies.
Cloudflare may improve eligible asset delivery, caching, compression, geographic latency, and origin load. It cannot automatically repair slow application code, database queries, or excessive client-side JavaScript.
Yes. Possible improvements include removing unused code, splitting bundles, dynamic imports, replacing heavy dependencies, delaying third-party scripts, reducing event-handler work, and moving appropriate logic server-side.
Yes. Image work may include resizing, compression, WebP or AVIF, responsive variants, lazy loading, CDN delivery, LCP prioritization, and dimensions and aspect ratios.
Yes. Common fixes include reserving space for images, embeds, forms, advertisements, fonts, and dynamic content. Some layout movement may require changes to the design or third-party widget.
Yes. INP optimization may involve reducing long tasks, script evaluation, event-handler work, rendering complexity, layout work, and third-party JavaScript.
Yes, when the required hosting and application access is available. Possible work includes page caching, object caching, database queries, APIs, server resources, hosting location, rendering, middleware, and CDN.
No. A caching plugin may help selected WordPress pages, but it cannot automatically resolve heavy JavaScript, large images, layout shifts, third-party scripts, database problems, slow APIs, poor architecture, or checkout complexity.
Yes. Incorrect caching may affect user accounts, carts, checkout, prices, currency, bookings, personalized pages, forms, and dynamic data. Cache exclusions and validation are essential.
I identify their performance cost and business purpose. The customer decides whether an important advertising, analytics, chat, booking, or compliance service can be removed or replaced.
Laboratory tools may show changes shortly after deployment. Search Console Core Web Vitals relies on aggregated field information, so it requires sufficient new user data before the reporting reflects updated performance.
Some URLs and origins may not have enough eligible field data. Laboratory testing and custom real-user monitoring can still be used for diagnosis and validation.
I normally test representative templates and high-priority URLs. Testing every individual URL may be unnecessary when many pages share the same code and layout.
Yes. Monitoring may include Core Web Vitals, PageSpeed tests, Lighthouse, template sampling, bundle sizes, page weight, server response, errors, and performance budgets.
The service can include audit, developer-ready recommendations, direct implementation, quality assurance, and post-launch monitoring. The exact scope depends on platform access and the customer’s development workflow.
The initial process normally requires website URL, main page templates, business-priority pages, Search Console access, analytics access, CMS or repository access, hosting access where relevant, Cloudflare or CDN access where relevant, GTM access, staging environment, recent deployment information, known performance problems, required third-party services, and a development contact where relevant.
