Seven ways to make a website faster and easier to use

Each service identifies specific causes, fixes them in order of effect, and checks the outcome with the same test used at the start.

Website Speed Optimization

A slow page rarely has one cause. We trace how a page loads from the first request to the moment it responds to input, separate the delays that matter from the ones that do not, and fix them in order of effect.

Benefits

  • Pages show useful content sooner, especially on slower connections
  • Less data and processing for each visit
  • A clear record of what changed and why

Typical problems

  • Slow server responses and missing caching
  • Render-blocking CSS, fonts and scripts
  • Pages that load far more than they use

Approach

  1. Measure representative pages under fixed test conditions
  2. Read the network waterfall and main-thread trace to find the cause
  3. Fix the largest delays first, then test again the same way

Core Web Vitals Optimization

Core Web Vitals are Google's measures of real page experience. We work out which element or interaction is responsible for a poor value, and fix that specific cause rather than chasing a general score.

Benefits

  • Work focused on the metrics that describe real experience
  • Less content jumping while the page loads
  • Faster visual feedback after clicks and taps

Typical problems

  • A late or oversized LCP element
  • Long JavaScript tasks that delay responses to input
  • Images, embeds and banners that shift the layout

Approach

  1. Check field data where it exists and use lab tests to reproduce issues
  2. Attribute each poor value to a specific element or task
  3. Confirm in the lab, then track field data as it updates

Image and Media Optimization

Images and video are often the heaviest part of a page. We set up responsive sizing, modern formats and sensible loading priorities, so quality holds up while the transfer size comes down.

Benefits

  • Smaller downloads, which matters most on mobile data
  • A faster main image and no layout shift from media
  • A repeatable process for future content

Typical problems

  • Large source files served to small screens
  • Missing width and height attributes
  • Lazy loading applied to the main image

Approach

  1. Audit each page's media by transfer size and display size
  2. Set up responsive images with AVIF or WebP where supported
  3. Prioritize the main image and defer what sits below the fold

Next.js Performance Optimization

Next.js provides strong performance tools, but they only help when used well. We review rendering and caching choices, trim client JavaScript and make sure static content is actually served as static.

Benefits

  • Less JavaScript to download, parse and run
  • Static content that responds quickly and stays cheap to serve
  • A codebase that is easier to keep fast

Typical problems

  • Client Components used where none are needed
  • Large libraries in shared bundles
  • Pages rendered per request when they could be static

Approach

  1. Inspect build output and bundle contents by route
  2. Move non-interactive UI to Server Components and replace heavy libraries
  3. Apply the caching model that fits the installed Next.js version

Technical SEO Improvements

Technical SEO removes the obstacles between good content and search engines. We review metadata, structure, crawl controls and structured data, and only add markup that accurately describes the page.

Benefits

  • Clear, page-specific titles and descriptions
  • Crawl and canonical signals that agree with each other
  • Accurate structured data that holds up to review

Typical problems

  • Duplicate or missing metadata
  • Broken heading structure
  • Incorrect canonicals, sitemaps or robots rules

Approach

  1. Crawl the site and compare it with what should be indexed
  2. Fix metadata, headings, canonicals and sitemap
  3. Validate structured data and monitor Search Console where available

Website Performance Audits

An audit gives your team a clear picture without any code changes. We test key templates, explain each issue in plain language and rank the recommendations by likely effect and effort.

Benefits

  • A prioritized list your developers can act on
  • Evidence behind each recommendation
  • A measured baseline for future comparison

Typical problems

  • Unclear reasons for poor scores
  • Automated reports with no priorities
  • No baseline to judge whether later work helped

Approach

  1. Agree the key pages and test conditions
  2. Test, diagnose and record the baseline
  3. Deliver ranked findings with implementation guidance

Mobile Performance Optimization

A page that feels instant on a fast laptop can struggle on a mid-range phone. We test under mobile throttling, reduce the work the device must do, and check that the page stays comfortable to use at small sizes.

Benefits

  • Better loading and response on less powerful devices
  • Less data used on mobile connections
  • Layouts and tap targets that work at small sizes

Typical problems

  • Heavy JavaScript that blocks slower processors
  • Desktop-sized images and assets on phones
  • Layouts that shift or overflow on small screens

Approach

  1. Test with mobile CPU and network throttling
  2. Reduce JavaScript and media for small screens
  3. Check real layouts and interactions at phone widths
