A link from another site to yours — a core authority signal, and part of the growth layer that builds on a solid foundation.
Backlinks are links from other websites pointing to your pages, and they're one of the strongest external authority signals. They're powerful — but they're the lights on the tree, not the roots. A backlink to a Search-Ready page passes its full value; a link to a broken or uncrawlable page largely leaks away.
Build the foundation first, then earn authority on top of it, and the links compound instead of being wasted.
