I am ready to launch a pretty big woocommerce site with more than 100K products. I consider the site to be far from finished, but I prefer to launch it and perfect it later after I have some customer feedback. I am a tech person so the design is not great, but I have tried my best for speed and SEO.
Every night I update all products and fetch new ones using WP All Import. I update the stock of the products every hour using custom code.
The site is on a dedicated server with a custom wp optimized environment, with redis object cache enabled. I started with redis full page caching, but I switched to litespeed cdn edge caching using quic.cloud just because the litespeed wordpress plugin is that good! Rest of the plugins I use for performance are:
Elasticpress ( With self hosted elasticsearch )
WP Scalability Pro
I have minimized external script usage using server side tag manager ( not quite ready ), and I removed many scripts and css i was not going to use. For example I replaced the default woocommerce product gallery with the splide.js that oxyninja provides.
For SEO I started with The Seo Foundation which seemed to be the most lightweight choice, but I preferred Seopress Pro as it has better oxygen compatibility and many features, without slowing the site.
The url is https://marketoupoli.gr and I would really appreciate some feedback.
