RankYak vs SEO.ai (2026): which should you pick?

Pick RankYak if

• Fits if you want keywords picked and articles posted on set days for one site
• Works for agencies adding client sites, as each one is billed at the same per-site price

Look elsewhere if

• Pricey if you run several sites, since every website is a separate $99 monthly subscription
• Tight if you want to test it properly, as the trial lasts 3 days and the backlink exchange only opens once you pay
• Watch out: Site Guard, which fixes titles, descriptions and cannibalization on existing pages, is $99 a month on top
• Watch out: output follows your publishing days, so weekdays only means about 21 articles a month, not 30
• Skip it if you want links from outside its network, as backlinks come only from other member sites

Pick SEO.ai if

• Fits if you own a small business site and want pages written and posted without doing it yourself
• Works for sites in a language other than English, with 50+ to pick from

Look elsewhere if

• Pricey if you have one small site, at $149 a month for one website in one language, before VAT
• Tight if you add a second site or language, which means Multi Site at $299 for three, $449 for five and $749 for ten
• Watch out: the 7-day trial rolls into a paid plan unless you cancel, and subscriptions are final with no refunds
• Watch out: backlinks come from a link exchange with sites in its network, not from outreach
• Watch out: paying yearly for the 25% saving binds you for the whole year
