How to improve PrestaShop site speed and SEO for a furniture store?

[Heaven and Home]

Hi everyone,

I’ve been working on a furniture website built with PrestaShop, and I’m trying to optimize it for both speed and SEO performance. The site is Heaven & Homes — a UK-based furniture and home décor brand.

The website runs fine, but I’m noticing slower load times on product category pages and sometimes layout shifts during image loading. I’ve already:

• Enabled caching and GZIP compression
• Optimized images with WebP
• Installed a few SEO and speed modules
• However, I still see CLS and LCP warnings in PageSpeed Insights.

Can anyone share their experience or best practices for improving PrestaShop Core Web Vitals and category-page SEO?

I’m particularly curious about:

Best lazy-loading setup for product images

Schema markup tools that work well with PrestaShop

Server or hosting tweaks that make a noticeable difference

Any help or example setups would be greatly appreciated — especially from other store owners who’ve optimized large image-heavy websites.

Thanks in advance!
