Influence your byline dates in Google Search
A byline date is the date that Google estimates that the web page was updated or published.
When Google can determine the byline date of your page or video, it can expose this information
in Search results, if this information is considered to be useful to
the user. You can provide information to help Google determine the byline date.
Google doesn't depend on a single date factor because all factors can be
prone to issues. That's why our systems look at several factors to determine our best estimate
of when a page was published or significantly updated.
How to provide date information to Google
To provide date information to Google, follow these steps:
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:
Posted Feb 4, 2019
Published February 4, 2019
Last updated: Feb 14, 2018
Updated Feb 14, 2019 8pm ET

Suppose you open Search Console and find out that your Google Search traffic dropped. What should you do?

</html>
Make your dates and times consistent. Ensure that the date (and optional
time and timezone) match between the equivalent user-visible and structured values. Time
and timezone are optional in user-visible data even if provided in structured data.
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 to the
page to describe the activities listed on the page, if you like.
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.

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)."]]
