I need comprehensive optimization for five of my WordPress websites, ensuring they deliver fast loading speeds and perform at peak efficiency. My primary goals are to significantly improve loading speed, resolve any caching issues, and enhance performance scores to pass Google PageSpeed Insights and achieve "everything in green." Additionally, I aim for top-tier results on GTmetrix. Currently, I use tools such as Litespeed cache for caching, Cloudflare as my CDN, and image optimization solutions like Smush. I’d like these tools fine-tuned or optimized further, and I’m open to recommendations or better alternatives if necessary. The deliverable is a noticeable improvement in performance metrics for all five websites, with measurable results on both Google PageSpeed Insights and GTmetrix. If you have expertise in WordPress performance optimization, please get in touch.
