Contadu vs Page Optimizer Pro (2026): which should you pick?

Pick Contadu if

• Fits if you run an agency planning and scoring content for several client sites
• Works for writers working in languages other than English

Look elsewhere if

• Not for you if you want a free plan, as there's only a 7-day trial
• Tight if you run more than 5 sites, since Freelance stops at 5 projects
• Skip it if you need extended API access or your own CMS in the editor, which wait on Enterprise at $293 a month
• Watch out: the same company sells NeuronWriter, which covers much of the same ground

Pick Page Optimizer Pro if

• Fits if you tune individual pages against what ranks on Google right now
• Works for agencies giving writers access through a secret key, without a login

Look elsewhere if

• Not for you if you want to try it first, as there's no free plan or trial, only a 7-day refund
• Tight if you're on Basic, as 20 credits is about 10 new reports a month
• Pricey if you run out of credits, with bundles from $15 for 10 up to $800 for 1,000
• Watch out: the API is a $10 a month add-on, costs 2 credits a call and is capped at 100 calls on Unlimited
• Pricey if your team is big, as Teams covers 5 sub-accounts and each extra one is $12 a month
