Someone to me: "Can you optimize this website for Page Speed Insight"

Me: "But it's a fucking Wordpress,.. Go home."

@DLMousey love the inline translations 🤘🏼

It's hard to know if your answer is legit or not without a bit of context.

You can definitely optimize a WP website for Page Speed Insight.

As an example, my personal blog, running on WP, has 100% PageSpeed and 88% YSlow on GTMetrix (not 100% because missing a CDN and because missing expires headers on Google fonts and analytics), and my company website gets 88% and 80% (in addition to previous reasons, GTMetrix don't like responsive images, cookies on assets and too many http requests), which I deem respectable.

But of course, if this is the place described by @DLMousey, yeah that's an appropriate response.

@Fradow very true. I believe you can optimise wordpress. But that needs to be thought from the start. I just got some legacy code (quite afraid of it) and it is a no-go in that context.. Dozens of plugins, all the crap you shouldn't do is there.. :/ So my answer still stands ^^

Oh yeah, existing WP base with legacy code/plugins are generally best left alone and recoded from scratch. I actually did that for my company website.

Old one had a fuckton of plugins, and piles of CSS done by interns without a single trace of refactoring.

@Fradow I feel your pain. The rebuild is also what I suggested ^^
