Farcaster clients render link previews using the standard og:image and og:title meta tags. A cast with a link to your essay or product page surfaces whatever your theme happens to ship, which for most WordPress sites is either the featured image or a stretched logo. The result is the same flat preview for every cast, no matter how different the underlying posts are.

SleekPixel writes a per-post 1200x630 PNG and the matching og:image meta tag. When the cast goes out on Farcaster, Warpcast pulls the image and renders the title, the author handle, and your brand mark next to the cast text. The preview reads as a piece of content rather than a generic link.

For Farcaster channels that focus on a specific topic, you can scope different templates to different post categories so a /design cast and a /dev cast surface with the right visual cue.

Farcaster is small enough that a coherent visual identity reads across the entire client. Posters who cast often with the same brand mark are recognisable in feed even before the cast text is read, and that recognition shifts the marginal recast and reply rate. The default WordPress OG image flattens that recognition because every cast surfaces the same logo regardless of the underlying post.

SleekPixel turns each link into a real preview by rendering a per-post card from real fields, which gives every cast its own moment in feed. The cost stays low because the render is automatic on save, and a brand refresh re-renders the archive so older casts in deep threads keep matching the current system.
