Supported Props
| Propname | Type | Description |
|---|---|---|
| title | string | The title of the page. |
| titleTemplate | string | Provide a title template to keep a consistent title style. %s — Astro SEO, %s will be replaced with your title, e.g. Homepage — Astro SEO |
| titleDefault | string | Fallback title that is used if no title is provided. |
| description | string | Text that gives a concise description of what your page is about. |
| canonical | string | Prevent duplicate content issues by specifying the "canonical" or "preferred" url of a web page. If you don't define this, Astro.url.href will be used as the default value. |
| noindex | boolean | Set this to true if you don't want search engines to index your page. Since this is an SEO component, this gets set to false by default. This way, indexing is strictly opt-out. |
| nofollow | boolean | Set this to true if you don't want search engines to follow links on your page. Since this is an SEO component, this gets set to false by default. This way, following links is strictly opt-out. |
| charset | string | Set the charset of the document. In almost all cases this should be UTF-8. |
| languageAlternates | Array<{ href: string; hrefLang: string }> | List of language alternates for the page. |
| openGraph.basic.title | string | Set the title Open Graph should use. In most situations, this should be different from the value of the title prop. See this tweet to gain an understanding of the difference between the two. If you define this, you must define two other OG basic properties as well: type and image. (Learn more.) |
| openGraph.basic.type | string | Set the type Open Graph should use. If you define this, you must define two other OG basic properties as well: title and image. (Learn more.) |
| openGraph.basic.image | string | URL of the image that should be used in social media previews. If you define this, you must define two other OG basic properties as well: title and type. (Learn more.) |
| openGraph.basic.url | string | The canonical URL of your object that will be used as its permanent ID in the graph. Most likely either the url of the page or its canonical url (see above). If you define this, you must define the other 3 OG basic properties as well: title, type and image. (Learn more.). If you define the other 3 OG basic properties but don't define this, Astro.request.url.href will be used as the default value. |
| openGraph.optional.audio | string | A URL to an audio file to accompany this object. |
| openGraph.optional.description | string | A one to two sentence description of your object. |
| openGraph.optional.determiner | string | The word that appears before this object's title in a sentence. An enum of (a, an, the, "", auto). If auto is chosen, the consumer of your data should chose between "a" or "an". Default is "" (blank). |
| openGraph.optional.locale | string | The locale these tags are marked up in. Of the format language_TERRITORY. Default is en_US. |
| openGraph.optional.localeAlternate | Array | An array of other locales this page is available in. |
| openGraph.optional.siteName | string | If your object is part of a larger web site, the name which should be displayed for the overall site. e.g., "IMDb". |
| openGraph.optional.video | string | A URL to a video file that complements this object. |
| openGraph.image.url | string | For now, setting this is ignored. This is done because og:image:url is supposed to be identical to og:image. If you have a use case where it makes sense for these to be different, please feel free to contact me, and tell me about it and I will consider adding it. Until then, in the interest of enforcing best practices, the value of this property will be ignored and og:image:url set to the value of openGraph.basic.image. |
| openGraph.image.secureUrl | string | Sets og:image:secure_url: An alternate url to use if the webpage requires HTTPS. |
| openGraph.image.type | string | Sets og:image:type. A MIME type for the image. e.g. "image/jpeg" |
| openGraph.image.width | number | Sets og:image:width. The number of pixels wide. |
| openGraph.image.height | number | Sets og:image:height. The number of pixels high. |
| openGraph.image.alt | string | Sets og:image:alt. A description of what is in the image (not a caption). If the page specifies openGraph.basic.image it should specify openGraph.image.alt. |
| openGraph.article.publishedTime | string | Sets article:published_time. The date the article was published. Must be a ISO 8601 DateTime string. |
| openGraph.article.modifiedTime | string | Sets article:modified_time. The date the article was last modified. Must be a ISO 8601 DateTime string. |
| openGraph.article.expirationTime | string | Sets article:expiration_time. The date the article will no longer be relevant. Must be a ISO 8601 DateTime string. |
| openGraph.article.authors | string[] | Sets article:author. The author(s) of the article, if it's only one, pass an array with one entry. If there are multiple, multiple tags with descending relevance will be created. |
| openGraph.article.section | string | Sets article:section. A high-level section name. E.g. Technology |
| openGraph.article.tags | string[] | Sets article:tag. Tag words associated with this article. If it's only one, pass an array with one entry. If there are multiple, multiple tags with descending relevance will be created. |
| twitter.card | TwitterCardType (string) | Sets twitter:card. The card type. Must be one of “summary”, “summary_large_image”, “app”, or “player”. |
| twitter.site | string | Sets twitter:site. (Twitter) @username for the website used in the card footer. |

| twitter.description | string | Sets twitter:description. A one to two sentence description of your object. |
| extend.link | Array<Link extends HTMLLinkElement { prefetch: boolean; }> | An array of free-form <link> you'd like to define. |
| extend.meta | Array<Meta extends HTMLMetaElement { property: string; }> | An array of free-form <meta> tags you'd like to define. |
Extending Astro SEO
With the v0.3.14 release, you can now define any <meta> and <link> tag you want using the extend prop. For example :
<SEO
extend={{
// extending the default link tags
link: [{ rel: "icon", href: "/favicon.ico" }],
// extending the default meta tags
meta: [
{
name: "twitter:image",
content:
"https://user-images.githubusercontent.com/5182256/131216951-8f74f425-f775-463d-a11b-0e01ad9fce8d.png",
},
{ name: "twitter:title", content: "Tinker Tailor Soldier Spy" },
{ name: "twitter:description", content: "Agent" },
],
}}
/>
Open Graph
Open Graph properties are passed as one object to the prop openGraph. The structure of this object is modeled after the Open Graph documentation itself. That means it uses nested objects to differentiate between basic and optional properties, as well as object specific ones. If you pass an openGraph config, you must define all 4 of the basic properties (title, type, image and url). The optional properties are all ... well, optional.
// TypeScript interface of openGraph prop
openGraph?: {
basic: {
title: string;
type: string;
image: string;
url: string;
},
optional?: {
audio?: string;
description?: string;
determiner?: string;
locale?: string;
localeAlternate?: Array<string>;
siteName?: string;
video?: string;
}
}
Goals
Our first goal for this project is to support the most-used tags that are relevant for SEO. That includes the most-used open graph tags.
After that comes feature-parity with Next SEO. After that ... we'll see.
What does this component do, exactly?
There's certainly no magic to what Astro SEO does. Basically, it bundles the
creation of regular SEO-relevant HTML tags inside one component that you can
then use inside your page's <head> tag.
The translation between props and tags is pretty direct and almost 1:1. After
building, there probably won't be anything you wouldn't have written yourself.
The idea is to surface the options that exist in a central place and adhere to
best practices where it's theoretically possible not to. If you want to see
how the sausage gets made, there's only one place you will have to check:
/src/SEO.astro
If you want, you can view Astro SEO as a checklist, so you don't forget a tag. Or maybe also as an educational tool, to see which options exist in the first place.
