This documentation provides technical information about which twitter tags Yoast SEO generates and outputs. These tags are only consumed by Twitter.
We output a variety of
<meta> tags for Twitter in the
<head> of each page, in order to better inform Twitter about the content of the page in question.
Note that for a lot of tags, Twitter falls back on OpenGraph metadata. Where it falls back, we provide the OpenGraph metadata and don't provide the Twitter tag specifically unless it has been customized.
The following tags provide social networks and platforms (e.g., Facebook, Twitter, Pinterest) with additional information about the page and its content.
Assuming that the respective admin settings are not disabled, these tags are output on all pages (except for error templates, which are described separately).
|The card type to use when previewing the page (defaulting to
|The twitter handle of the site owner/operator.

"Enhanced Slack sharing" tags
We utilize Twitter's "label/data" meta tag format to add additional data, which is shown when sharing URLs on Slack. Note that this should only be output if the "Enhanced Slack sharing" setting is enabled for the site.
<meta name="twitter:label1" content="Est. reading time" />
|Only output on
<meta name="twitter:data1" content="%x% minutes" />
%x% is the estimated reading time, rounded down to the closest minute.
