Fixes written for the stack you actually run
You don't need another list of warnings.
Generic tools say "reduce unused JavaScript" and leave you guessing which plugin, which file and which setting. We do the detective work and hand you the answer.
"OK… but what do I actually change?"
Elementor → Settings → Features → set Inline Font Icons to Active. Removes a 74 KB render-blocking font.
WP Rocket → File Optimization → Delay JavaScript execution. Add fbevents.js and analytics.tiktok.com. Tracking still fires.
Add to urban-wear-child/style.css: .site-header{min-height:84px}. Fixes the header jump on load.
Same problem. Different fix on every platform.
A slow hero image is a header.php edit on WordPress, a Liquid change on Shopify and a one-word prop on Next.js. We know the difference.
Your theme marks the LCP image as lazy, so the browser fetches it last.
change loading="lazy" → fetchpriority="high"
Contact Form 7 and slider assets load on all 42 pages. They're used on 2.
add wp_dequeue_script('contact-form-7') unless is_page('contact')

then upload WOFF2 files to /fonts and add @font-face

delete {% render 'bold-subscriptions' %} and 2 more
Review and chat widgets block the main thread on product pages.
Products are indexed under /collections/*/products/* as well as /products/*.
change product.url | within: collection → product.url
next/image lazy-loads by default, including your hero.
add <Image … fetchPriority="high" loading="eager" />
Intercom adds 290 KB to the initial bundle on every route.
use <Script strategy="lazyOnload" /> instead of a raw <script>
Removes a render-blocking request and the font swap layout shift.
use import { Inter } from 'next/font/google'
/blog/[slug] pages all share the same title.
add export async function generateMetadata()
Webflow lazy-loads every image by default.
An opacity-0 interaction delays your LCP by 1.1s.
