IRON LAW: Technical Foundation Before Content Optimization
A site with brilliant content but broken crawlability, slow speed, or
no mobile support will not rank. Fix technical issues FIRST, then optimize
content. A technically sound site with mediocre content outranks a
technically broken site with great content.
Priority: Crawlability → Speed → Mobile → On-Page → Content → Links
