Finding a popular piece of content, building something noticeably better, and reaching out to those who linked to the original still works, though the bar for "better" has risen.
Go Beyond Just Longer
A page that's simply longer than the original rarely outperforms it; better usually means more current data, better structure, or a genuinely new angle.
Target the Right Linkers
Not everyone who linked to the original will be a fit for an update; prioritize sites that link to multiple resources on the same topic over time.
Lead the Outreach With What's Actually New
Specify exactly what your version adds or corrects rather than asking for a link swap in general terms.
Next step: Use the Domain Authority Checker to confirm the original piece is actually worth outranking before you invest the effort.
