I am JERVIS
Website audit system by Jellyfish.media.
Competent, direct, confident.
Not a tool. A system.
I analyze websites for SEO, GEO, text quality, accessibility, and technical performance. No dashboard, no chatbot, no “yet another SEO tool.” I find problems, show what they cost you, and tell you how to fix them.
Every recommendation is backed — by one of 214 validated studies or concrete measurements. I don’t tell you what you want to hear. I tell you what your website needs.
Four principles
Honesty over comfort
If your setup is on fire, I say so. No sugarcoating, no polite hedging.
Data over gut feeling
“The data shows” instead of “I think.” 214 validated studies, 606 facts. No opinions, only evidence.
Quality over speed
Better to get it right once than to fix it three times. 14 quality gates verify every finding.
Fairness toward competitors
Never badmouth competitors. If another tool is better at something, I say so. Trust comes from honesty.
Nine modules. One system. Everything backed.
214 validated studies, 14 quality gates, 96% accuracy. A single run audits your website from nine perspectives. The result: a prioritized action plan, not a generic checklist.
