How
No JS execution, no headless browser on the free audit — just a fast HTML parse. Paid plans add real Core Web Vitals from visitor browsers via the Connector.
Privacy
We never store cookies or personal data. The Connector transmits anonymous performance metrics only. GDPR-compliant by design.

FAQ

Common questions.

Does Fertilyze replace Yoast / RankMath?
No. Fertilyze is an intelligence layer ON TOP of your existing SEO tool. Keep Yoast, keep RankMath — Fertilyze reads them, learns your config, and adds what they can't: real browser telemetry, AI search monitoring, autonomous fixes, and weekly growth plans.
What does AutoFix actually change on my site?
AutoFix can rewrite meta titles/descriptions for optimal length and keywords, inject missing JSON-LD schema, add alt text to images, fix canonical URLs, and add noindex to low-value pages. Every change is logged and reversible with one click.
How does AI Search Visibility work?
We query platforms like Perplexity, Google AI Overviews, and Bing Copilot with your target keywords. If your domain is cited in their responses, we track it. If it's not, we tell you exactly how to structure your content to get cited.
Can I use Fertilyze on non-WordPress sites?
Yes. The JS snippet works on Shopify, Webflow, Wix, Squarespace, Next.js, or any HTML site. Monitoring and reporting work everywhere. AutoFix (automatic changes) is currently WordPress-only.
What happens if I cancel?
Your Seed plan is free forever. If you cancel a paid plan, AutoFix stops applying new changes (existing ones stay). Monitoring stops. Your Growth Plans stop. Basically: the fertilizer stops flowing, and your competitors keep growing.
Is it safe? Will it break my site?
The Connector is read-only by default. AutoFix changes only meta tags and schema — never your actual content or design. Everything is reversible. We've tested on 500+ WordPress configurations.

Your competitors already fertilize.
Don't let them outgrow you.

Plant the Connector. Activate your license. Watch the difference.
