Accelerating WordPress/WooCommerce site: PageSpeed Mobile

Comprehensive performance optimization and bug fixing for the online store caravella.net.ua (WordPress, Woodmart theme + Elementor, WPML).

Initially, the site had a low score on Google PageSpeed Insights (for example, 52 points on mobile for product pages), suffered from significant layout shifts (CLS), slow loading (FCP/LCP), blocking resources (CSS/JS), and a number of functional bugs, including incorrect operation of "Favorites" in different languages.

Completed works:
Deep audit of Core Web Vitals: Identified and eliminated the causes of high CLS (related to the product gallery) through precise CSS adjustments.

Resource optimization: Set up effective compression, conversion of images to WebP (Imagify), and optimization of their delivery; optimized font loading (local storage, woff2, preload).

Code optimization: Fine-tuned caching and optimization plugins (including switching from Apache+WP Rocket to OpenLiteSpeed+LiteSpeed Cache) for asynchronous/deferred loading of CSS/JS, eliminating blocking resources, and removing unused code.

JavaScript debugging: Found and fixed JavaScript conflicts causing errors in the product gallery, dynamic functionality ("Favorites" considering WPML), and pop-ups by precisely adjusting exceptions for deferred JS execution (Delay JS).

Server issue resolution: Diagnosed and resolved the slow server response issue (TTFB) and 503 errors.

Result:
Mobile Google PageSpeed score for product pages (example: /rozsuvni-peregorodky/aliuminievi/tovar-01) increased from 52 to 92 points.

All Core Web Vitals metrics (LCP, FCP, TBT, CLS) significantly improved.

Critical functional bugs affecting user experience were eliminated.

Overall stability and speed of the site and all its pages were enhanced!
