# meta data

> Usage: `{{meta_title}}` and `{{meta_description}}` and `{{canonical_url}}`

***

Ghost generates automatic meta data by default, but it can be overridden with custom content in the post settings menu. Meta data is output by default in [ghost\_head](/themes/helpers/utility/ghost_head_foot/), and can also be used in themes with the following helpers:

* `{{meta_title}}` – the meta title specified for the post or page in the post settings
* `{{meta_description}}` – the meta description specified for the post or page in the post settings
* `{{canonical_url}}` – the custom canonical URL set for the post
