4SEO vs Seobility (2026): which should you pick?

Pick 4SEO if

• Fits if your Joomla site wants one extension instead of several SEO add-ons
• Works for site owners who plan content from Search Console data

Look elsewhere if

• Skip it if your site isn't on Joomla, as that's all it runs on
• Not for you if you want to try it first, since there's no free edition or stated trial
• Pricey if you run more than 3 sites, as unlimited sites need PRO at $249 a year
• Watch out: it keeps working after a year, but downloads and helpdesk access stop until you renew

Pick Seobility if

• Fits if you want audits and rank tracking for a small site, from $55.92 a month on yearly billing
• Works for site owners who want uptime alerts in the same place as their SEO

Look elsewhere if

• Tight if you stay free, at 100 pages per crawl started by hand, 10 tracked keywords and a wait between crawls
• Skip it if you want to track your brand in AI answers, which is listed as coming soon
• Not for you if you need it to connect to other tools, as no integrations or API are listed
• Pricey if you need white-label reports or team members, which start on Professional at $109.90 a month
• Watch out: extra projects are $5.90 to $16.90 a month each, 100 more keywords $7.90 to $11.90, and daily tracking past page two costs extra

4SEO

• Runs only on Joomla (versions 3, 4, 5 and 6).
