How to optimize mopamotorparts.com
CSS and JavaScript files are blocking initial page render and delaying First Contentful Paint by 1.9 seconds.
Inline critical CSS for above-the-fold content directly in the HTML. Move the 162KB all.css file to load asynchronously using media='print' onload="this.media='all'". Defer jQuery and other non-critical JavaScript until after page load using the defer attribute.
A score of 45 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.

Measures visual stability - how much content shifts during page load
This motor parts website has poor performance with a score of 45/100, indicating significant speed issues that will frustrate users. The biggest problem is render-blocking resources (CSS and JavaScript files) that delay page loading by nearly 2 seconds, combined with poorly optimized images that waste 252 KB of bandwidth. The site takes over 10 seconds to become fully interactive and loads its main content in 10.8 seconds - far too slow for good user experience. Fixing these issues by compressing images, minifying CSS/JavaScript, and removing unused code could potentially improve the performance score by 30+ points and dramatically reduce loading times.
Why It Matters:
Images are causing a 900ms delay to LCP and consuming 252KB of unnecessary bandwidth.
How to Fix:
Increase compression on the warehouse sale banner (188KB savings) and logo (44KB savings). Resize the 300x300 logo to its displayed 105x105 dimensions. Add responsive image srcsets to serve appropriately sized images for different screen sizes.
Why It Matters:
Missing image dimensions cause layout shifts and lack of priority hints delays LCP image discovery.
How to Fix:
Add explicit width and height attributes to all images, especially the hero image and logo. Add fetchpriority='high' to the LCP image (MOPA Männchen). Reserve layout space with CSS to prevent content jumping during image load.
Once your site is optimized, maintain that speed. Use DeployHQ for zero-downtime, automated deployments—so performance fixes and updates go live safely every time, without breaking your site.
