Defer Render Blocking JavaScript. Adds the defer attribute to front end scripts so they download in parallel and execute after HTML parsing. Configurable exclusions for jQuery, WooCommerce, reCAPTCHA, and others.
HTML Minification. Strips whitespace, comments, and unnecessary characters from HTML, CSS, and inline JavaScript. Shaves 5 to 15 percent off page size without layout changes.

Fill in your site name, home title, and home description (140 to 155 characters). These feed into JSON-LD schema and OpenGraph tags.
Add your name, job title, profile URL, and headshot link. Add social profiles (LinkedIn, GitHub, etc.) one per line in the SameAs field. Google uses this to build your author entity.

Go to console.anthropic.com, create an account, navigate to Settings > API Keys, and create a key. It looks like sk-ant-api03-... and you only see it once.
Back in WordPress, go to Tools > CloudScale SEO AI > Optimise SEO tab, paste your key into the API Key field, click Test Key, then Save AI Settings.
The plugin never sends your key to any third party. It calls the Anthropic API directly from your server.
For Google Gemini, follow the instructions at ai.google.dev/gemini-api/docs/api-key.
