Quick answers

Which should I buy first?

If you do not yet know what to write about, research comes first. If you already have a topic list, an optimization tool may help sooner.

Can one replace the other?

Not fully. They overlap around content ideas, but Semrush covers technical and competitive data that Surfer does not focus on.

Does this page earn money if I sign up?

Possibly. The buttons use affiliate links, so we may earn a commission at no extra cost to you. It does not change the price you pay or which tool we say fits you.
