Fix Your LCP Score on Key Pages with AI
Preload the hero image and give it priority so your key pages start drawing their main content sooner.
Prerequisites
A connected site, the Code Snippets plugin (the AI can install it), and PageSpeed Insights to measure the result.
On [my site], look at [page URL] and tell me which element is most likely the Largest Contentful Paint, probably the hero image. Then add a preload hint in the head for that image and set fetchpriority to high on it, scoped only to this page so no other page is affected. Build it as a Code Snippets entry, save it inactive, and show me the head markup before and after so I can confirm you targeted the right image. Wait for my approval before activating. Do not edit my theme files. Remind me to run PageSpeed Insights on this page before and after so I can measure the change myself.

Skip the copy-paste. Just ask your AI for the “Fix Your LCP Score on Key Pages with AI” recipe, or describe the task, and WPVibe runs these steps on your own site.
The biggest image on your landing page, the hero, is usually the last thing the browser decides to load. It sits in your markup with no priority, so the browser discovers it late, fetches it after the stylesheets and scripts, and your visitor stares at a half-drawn page while the main picture drifts in. Google measures exactly this moment, the Largest Contentful Paint, and a slow hero is the most common reason a page fails it.
WPVibe finds the element that is likely your LCP on a page you name, then adds two things the browser understands: a preload hint in the head so the hero starts downloading immediately, and a fetchpriority of high so it jumps the queue ahead of less important images. On a test page we confirmed both landed, the preload link in the head pointing at the hero and fetchpriority high on the image itself, and that a different page did not get the hint. It is built as a Code Snippets entry scoped to the page you chose, so it never reprioritizes the wrong image elsewhere.
Paste the prompt and name the page plus which image is the hero. The AI adds the preload and priority hints, scoped to that page, and shows you the head markup so you can confirm the right image was targeted. Two honest notes: this changes how early the hero loads, not your score directly, so measure with PageSpeed Insights before and after on the real page. And recent WordPress already marks the first large image as high priority on its own, so on some pages the win is the explicit preload rather than the attribute.
Outcome
The hero image on your chosen page has a preload hint and fetchpriority high in the page head, scoped to that page only.
