Remove Unused JavaScript Code
High Impact+15 points estimated
Why It Matters
678KB of unused JavaScript is blocking page rendering and contributing to the poor 330ms First Input Delay score.
How to Fix
Audit and remove unused reCAPTCHA code (247KB unused). Lazy-load the Algolia search library (95KB) only when search is triggered. Remove or defer unused Google Tag Manager scripts until after page interaction. Use tree-shaking to eliminate dead code from remaining bundles.

What This Score Means
A score of 40 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This website has severe performance problems with a score of only 40/100, indicating major issues that are hurting user experience. The biggest problem is an enormous amount of unused JavaScript (678 KiB) and CSS (108 KiB) that's blocking the page from loading quickly, causing your First Contentful Paint to take a painful 5.3 seconds and Largest Contentful Paint to reach 20.3 seconds. The site is also suffering from multiple redirects that add nearly a second of delay, plus poorly optimized images that are much larger than needed for their display size. Cleaning up unused code, fixing the redirect chain, and properly sizing images could dramatically improve your performance score by 30+ points and make the site load several seconds faster for users.
Other Optimization Recommendations
Eliminate Multiple Page Redirects
High Impact+12 points estimatedWhy It Matters:
The redirect from bissell.nl to www.bissell.nl adds 780ms delay to every page load and directly impacts LCP by 800ms.
How to Fix:
Configure your web server to serve content directly from www.bissell.nl without redirects. Update all internal links to use the canonical www version. Set up proper DNS and server configuration to avoid the redirect chain entirely.
Optimize Critical CSS Loading
High Impact+18 points estimatedWhy It Matters:
Render-blocking CSS delays First Contentful Paint by 2.15 seconds with 97% of theme.css being unused above the fold.
How to Fix:
Extract critical above-the-fold CSS and inline it in the HTML head. Load the remaining theme.css asynchronously using media='print' onload technique. Remove unused CSS rules or split into separate files that load only when needed. Consider using a tool like Critical or PurgeCSS to automate this process.
