Content Delivery API > SEO and favicon

SEO and favicon

While you can fetch the content of a "SEO and Social" field just like any other field, the GraphQL API exposes on every record a much simpler _seoMetaTags field that you can use to easily get HTML meta tags based on the information present in the record itself:

How are _seoMetaTags generated?

Meta tags are generated merging the values present in the record's "SEO and Social" field, together with the global SEO Preferences that you can configure in the Content tab.

If the record doesn't have a "SEO and Social" field, the method tries to guess reasonable values by inspecting the other fields of the record (single-line strings and images).

title, og:title, twitter:title

These tags will be composed by concatenating the title of the record together with the Title suffix setting. If no "SEO and Social" field is present, or the title is not specified, the tags will be generated from the title provided in the global SEO settings.

If the total length of the title exceeds 60 characters, the suffix will be omitted.

description, og:description, twitter:description

These tags are generated using the description field in the "SEO and Social" field. If no such field is present, or the description is not specified, the tags will be generated from the description specified in the global SEO settings.

og:image, og:image:width, og:image:height, og:image:alt, twitter:image, twitter:image:alt

These tags are generated using the image field in the "SEO and Social" field. If no such field is present, or the image is not specified, the tags will be generated from the image specified in the global SEO settings.

robots noindex

A robots noindex tag will be added if either global SEO Preferences or the "SEO and Social" field have a "Prevent from being indexed by search engines" enabled.

og:locale

This tag is generated using either the locale specified in the query filter, or the main locale.

og:type

If the model is a singleton an og:type of type website will be returned, otherwise an og:type of type website will be returned.

og:site_name

The tag is generated from the site name attribute (if provided)

twitter:site

The tag is deduced from the twitter_account attribute (if provided)

twitter:card

The tag is generated from using the twitter_card field in the "SEO and Social" field. If no such field is present, the global SEO settings will be used.

article:modified_time

This tag is generated using the updated_at meta attribute of the Record

article:publisher

The tag is deduced from the facebook_page_url attribute (if provided)

Favicon meta tags

Similarly, you can get the meta tags needed to properly show the site's favicon with the _faviconMetaTags attribute contained inside the _site field:

iOS and MS app icons

If you're building an app, you can request additional meta tags with the variants argument:
