Influir en las fechas de firma en la Búsqueda de Google
Una fecha de firma es la fecha en la que Google estima que la página web se ha actualizado o publicado.
Si Google puede determinar la fecha de firma de tu página o vídeo, podrá mostrar esta información en los resultados de la Búsqueda si se considera que es útil para los usuarios. Puedes proporcionar información para ayudar a Google a determinar la fecha de firma.
Google no se basa únicamente en un indicador al determinar la fecha, ya que todos pueden presentar problemas. Por este motivo, los sistemas de Google tienen en cuenta varios factores para estimar en qué fecha se publicó o se actualizó de manera considerable una página.
Añade una fecha que los usuarios puedan ver en un lugar destacado de la página. Marca las fechas de forma adecuada con texto como "Fecha de publicación" o "Última actualización". A continuación se muestran algunos ejemplos de cómo puedes destacar la información de fecha en una página web:
Publicado el 4 feb. 2019
Publicado el 4 de febrero del 2019
Última actualización: 14 de febrero del 2018
Actualizado el 14 de febrero del 2019 a las 20:00 GMT

Prácticas recomendadas para influir en las fechas de firma
La fecha es obligatoria, pero la hora no: de todas formas, te recomendamos que incluyas una hora y una zona horaria en las etiquetas para que la información sea más precisa.
Pon fechas y horas coherentes. Comprueba que la fecha (así como la hora y la zona horaria, que son opcionales) que es visible para los usuarios y la de los datos estructurados sea la misma.
No especifiques fechas que estén en el futuro ni relacionadas con lo descrito en la página.
Las fechas deben indicar el día en que se publicó o se actualizó la página, y no el de las historias o eventos que se mencionen en ella. Si quieres, puedes añadir marcado de evento para describir los acontecimientos que se mencionan en la página.
Procura que no haya más fechas de las necesarias en la página: si has seguido las prácticas recomendadas anteriores, pero notas que se están seleccionando fechas incorrectas, te recomendamos que quites las otras fechas que aparecen en la página.

You can provide information to help Google determine the byline date.\nAn illustration of a text result in Google Search, with a highlighted box around the byline date part Curious Panda\n[Why are sloths so slow?](https://wikipedia.org/wiki/Sloth)\n25 Aug 2023\n\nGoogle doesn't depend on a single date factor because all factors can be\nprone to issues. That's why our systems look at several factors to determine our best estimate\nof when a page was published or significantly updated.\n\nHow to provide date information to Google\n-----------------------------------------\n\nTo provide date information to Google, follow these steps:\n\n1. Follow the [best practices for influencing byline dates](#guidelines).\n2. Add a user-visible date to the page and feature it prominently. Label your dates appropriately with text like \"Publish\" or \"Last updated\". Here are some examples of how you can highlight date information about a web page:\n - **Posted Feb 4, 2019**\n - **Published February 4, 2019**\n - **Last updated: Feb 14, 2018**\n - **Updated Feb 14, 2019 8pm ET**\n\n You can provide a publication date and/or a last updated date. \n\n ```text\n \u003chtml\u003e\n \u003chead\u003e\n \u003ctitle\u003eAnalyzing Google Search traffic drops\u003c/title\u003e\n \u003c/head\u003e\n \u003cbody\u003e\n \u003cp\u003e\n Posted Tuesday, July 20, 2021\n \u003c/p\u003e\n \u003cp\u003e\n Suppose you open Search Console and find out that your Google Search traffic dropped.

We recommend that you add a subtype of [`CreativeWork`](https://schema.org/CreativeWork) (such as [`Article`](/search/docs/appearance/structured-data/article), [`BlogPosting`](https://schema.org/BlogPosting), or [`VideoObject`](/search/docs/appearance/structured-data/video)), and specify the `datePublished` and/or `dateModified` fields.

Time and timezone are optional in user-visible data even if provided in structured data.\n- **Don't specify future dates, or the date of the action described on the page.** The dates must describe the publication or update date of the page, not the stories or events described therein. You can add [Event markup](/search/docs/appearance/structured-data/event) to the page to describe the activities listed on the page, if you like.\n- **Minimize the presence of other dates on the page:** If you've followed the best practices and find incorrect dates are being selected, consider removing some or all other dates that appear on the page.\n- **If your page is intended to show up in Google News search** , follow [these additional guidelines](https://support.google.com/news/publisher-center/answer/9607104)."]]
