原文外掛簡介
Hydrogen SEO is a lightweight, AI-powered SEO plugin for WordPress. It writes your meta titles and descriptions, generates schema markup, fills in image alt text, and audits your site for the on-page issues that hold rankings back — all from a fast, modern dashboard and directly inside the block editor.
It is built for how search works now: not just Google, but AI answer engines like ChatGPT and Perplexity that read your pages and cite them in answers.

Free account for AI features
The AI features are powered by the Hydrogen SEO API. Create a free account at hydrogenseo.com, connect it from the plugin in one click, and you get free AI credits to start with. All non-AI SEO features (titles, meta, schema, sitemaps, robots, redirections, previews) work without an account.
External services
This plugin relies on the following third-party/external service. It is described below so you know what data is sent, when, and under which conditions.
Hydrogen SEO API
The plugin connects to the Hydrogen SEO API (hydrogenseo.com) to power its AI features: content generation, metadata (SEO title/description) generation, image alt-text generation, AI image generation (for featured images), and business/local schema generation.
Data is sent only when you actively use an AI feature. Depending on the feature, the request includes the text or image you ask it to work with (for example a topic, the content to improve, an image URL for alt-text, a prompt for image generation, or your business details for schema) and your configured API key. When you connect your account, your site URL and the name and email you choose to provide are sent so that an API key can be issued. In the setup wizard you may optionally enter your name and email; if you do and you tick the consent checkbox, they are sent with your site URL so we can send you setup help and product updates. Both fields are optional, the wizard can be skipped, and nothing is sent if you leave them blank or do not consent. The plugin does not send this data in the background or without a user action.
