The #potter hub on PornCaptions pins together every caption post where that tag is the real browsing signal, not a throwaway label bolted onto an unrelated frame.
The internal-link graph around #potter is dense on purpose: related tags at the top, most-viewed further down, and every card links out to its own individual post page with its own share preview.
The tag's structured data (Schema.org CollectionPage + BreadcrumbList) is emitted on every render, so Google and Bing treat this as a real porn caption sub-hub rather than a query results dump.
Every visit reshuffles the sort weights slightly, so the same #potter archive rewards repeat trips — the top of the grid tomorrow won't be identical to today.
Every #potter post is a standalone URL with its own share preview, alt text and interaction counts.
