Yoast Duplicate Post is the plugin almost every editorial WordPress site reaches for when a post needs a substantial update. The Rewrite and Republish flow creates a clone in wp_posts, lets the editor work on the clone safely, then merges the new post_title, post_content and post_excerpt back into the original on publish. The relationship is tracked in wp_postmeta under _dp_original, and the republish event fires the dp_after_republish action.

The detail that breaks most editorial workflows is the share image. When the clone merges back, the cached OG image URL in wp_postmeta still points at the picture rendered the first time the post went out. Readers see the old headline, even though the rewritten post has a new angle. SleekPixel hooks the same dp_after_republish action, reads the merged fields, renders a new PNG into uploads, and overwrites the og:image meta on the original.

The piece that matters is the timing. The new image is in place before the next scraper recrawl. Slack, LinkedIn and Facebook all see the fresh card the next time the URL flows through a share, no manual export step in the loop.

Yoast Duplicate Post is the plugin that makes the rewrite-and-republish workflow safe on WordPress. Editors clone the post, work on the clone, and merge the new content back into the original only when the rewrite is ready. The reason the workflow exists at all is that a published post should not flicker between drafts in front of readers.

The piece that the workflow does not solve is the share image. The merged post inherits its featured image and its OG image cache from the original, which means readers on social see the old headline next to the old picture even after the post has been completely rewritten. SleekPixel closes that loop.

The plugin hooks the republish event the same way Yoast Duplicate Post does, reads the merged title and excerpt off the live post, and renders a new share card before the next scraper recrawl. A republish on a SleekPixel site means a fresh image on every channel where the post will be shared, with no manual export step in the editor's loop and no need to remember which posts were republished last week.
