Smash Balloon's Instagram Feed plugin registers a custom post type called sbi_feeds for every feed an editor configures in the admin. The fetched Instagram posts get cached in a custom table called wp_sbi_feed_caches, keyed by feed id, with timestamps for when each cache slot was refreshed.

Embedding a feed in a post is done with [instagram-feed feed=4] or with the Smash Balloon block. Either way, what looks like rich content to the visitor looks like a token to default OG generators. Yoast or Rank Math sees only a shortcode in post_content and falls back to the featured image or to a site default.

SleekPixel parses the Instagram Feed shortcode, looks up the matching sbi_feeds CPT, reads the handle or hashtag, the feed type, and the post-cache count, then renders a per-feed OG image. When a visitor shares the post, the preview now names the feed, hints at its size, and matches the brand of the account being shown.

When a visitor lands on a page that embeds an Instagram feed, the feed is almost always the point of the page. The surrounding copy is a frame for it. A reader who decides to share that page is sharing the feed itself: this creator, this hashtag, this campaign.

A default OG image that says only the site name strips out the feed identity at exactly the moment the link is being passed around. A SleekPixel card that names the handle, badges the feed type, and stamps the freshness of the cache restores that identity. The fields are already in Smash Balloon's database.

The plugin already stores the handle, the type, and the cache age. SleekPixel reads from where the plugin already writes and refreshes the OG image alongside the cache refresh. Across a year of weekly cache cycles on a dozen feeds, that is hundreds of automatically refreshed social previews, every one of them naming the actual feed behind the embed.
