Most WordPress sites lose search traffic to SEO work nobody has time to do. Meta descriptions go unwritten, images ship with no ALT text, and related posts never get linked. Yoast and RankMath give you the fields; you still fill in every one yourself.

CloudScale SEO AI Optimizer fills them in automatically. On publish, the AI Auto Pipeline writes the meta description, scores the SEO, generates ALT text, builds an on-page summary, and links related articles. One-click Audio Narration turns any post into a spoken article in 11 AI voices. It also runs the technical SEO WordPress skips underneath, and a built-in Site Audit scores your setup across 20+ checks with one-click fixes.

It replaces Yoast Premium and RankMath Pro, in two plans:

Bring Your Own API Key – free, forever. Paste your own Anthropic Claude, Google Gemini or OpenAI key (2 minutes at console.anthropic.com, aistudio.google.com or platform.openai.com) and pay the provider directly: about $0.50-$1.50 per 200 posts, under $0.10 per 100 on Claude Haiku, or nothing on Gemini’s free tier. Setup is install, paste key, click Generate Missing.

Managed Subscription – $10 per month. No API key required, AI usage and audio narration included, cancel anytime.
