The web-to-Confluence migration pattern
For each external URL you want to migrate: convert to Markdown (via mdisbetter.com/convert/url-to-markdown for one-offs, or via your own Trafilatura/Readability pipeline for bulk), then either paste into a new Confluence Cloud page (which auto-converts on paste) or import via a Markdown-import plugin on Server/DC. The result is a native Confluence page where every heading, list, table, and code block is an editable Confluence block.
Common use cases: building a team handbook from various external sources; archiving external blog posts into the team wiki for offline access; consolidating vendor documentation into a single searchable Confluence space.
Why this beats "paste the URL into Confluence"
Pasting a URL into Confluence gives you a link preview card — useful as a bookmark, useless as content. Converting first means the actual content lives in Confluence: indexed by Confluence search, surfaced in the wiki's side navigation, citable from other pages, editable inline.
