"og:title": "rating · Meta Tag · zhead" --- Meta tags # rating Marks a page as containing sexually explicit adult content so Google can filter it in SafeSearch. It is not a general age rating system. ## Parameters adult Marks the page as containing sexually explicit adult content. ``` ``` RTA-5042-1996-1400-1577-RTA An equivalent RTA label that Google also recognizes as explicit. ``` ``` ## Code examples Good example ``` ``` The simple value Google recommends for a page with sexually explicit content. Good example ``` ``` The equivalent RTA value recognized by Google. You only need one of the two supported values. Avoid this example ``` ``` Google does not use this tag to certify that a page is suitable for every age. Avoid this example ``` ``` This is not a supported SafeSearch rating value. ## Recommendations - 01 Mark Every Explicit Page Google recommends adding the tag to each page with sexually explicit content. - 02 Use One Supported Value Choose adult or the RTA label. Both mean the same thing to Google, so adding both is unnecessary. ## Related documentation - [Google Search Central: Guidelines](https://developers.google.com/search/docs/specialty/explicit/guidelines#add-metadata) - [Google Search Central: Special Tags](https://developers.google.com/search/docs/crawling-indexing/special-tags#rating) ## Related meta tags ### [charset](https://zhead.dev/meta/charset) charset Declares the character encoding used by the HTML document.
