On-page vs off-page SEO
On-page SEO is everything you optimise on your own pages (content, HTML, structure); off-page SEO is the authority you earn elsewhere (backlinks, mentions, reputation).
The difference
On-page is within your control, write great content, structure it well, optimise titles and links. Off-page is earned, other sites linking to and talking about you, which signals trust you can't set yourself.
You need both
On-page makes you relevant and eligible; off-page makes you trusted enough to outrank equally-relevant competitors. Strong content earns the links; links lift the content. They compound together.
Frequently asked
Both, on-page gets you in the race, off-page authority often decides who wins among relevant pages.
