astro-seo
Astro SEO is a component for adding search engine optimization metadata tags to an Astro app.
About astro-seo
Astro SEO is an open source component for Astro projects. It adds search engine optimization metadata tags to the head section of Astro pages. It is installed with npm or yarn and placed inside the HTML head. A common approach is to place the component in a shared layout and pass page-specific values from each page through Astro's standard props.
The component's props cover the page title and a title template, a fallback title, the page description, and the canonical URL. It also handles robots directives such as noindex, nofollow, noarchive, and nocache, along with a field for custom directives. The README example also shows Open Graph and Twitter fields, plus an extend option for adding custom link and meta tags. The homepage excerpt is cut off partway through the props table, so the full list of props is not confirmed here. The excerpt does not state which Astro versions are supported or describe any other limits.
