서명일은 Google에서 웹페이지를 업데이트하거나 게시한 것으로 추정하는 날짜입니다.
Google에서 페이지나 동영상의 서명일을 확인할 수 있고 이 정보가 사용자에게 유용한 것으로 간주되는 경우 검색결과에 이 정보를 노출할 수 있습니다. Google에서 서명일을 결정하는 데 도움이 되는 정보를 제공할 수 있습니다.
어떤 요소든지 문제가 발생할 소지가 있기 때문에 Google에서는 한 가지 날짜 요소에 의존하지 않습니다. 따라서 Google 시스템은 페이지가 게시되었거나 중요한 업데이트가 이루어진 시기를 최선으로 예상하기 위해 여러 요소를 살펴봅니다.
사용자가 볼 수 있는 날짜를 페이지에 추가하고 눈에 잘 띄게 표시합니다. 날짜에 '게시' 또는 '최종 업데이트' 같은 텍스트로 적절하게 라벨을 지정합니다. 다음은 웹페이지에 관한 날짜 정보를 강조표시하는 방법의 예입니다.
게시 날짜: 2019년 2월 4일
2019년 2월 4일에 게시됨
최종 업데이트: 2018년 2월 14일
업데이트 날짜: 2019년 2월 14일 오후 8시(동부 표준시)

날짜와 시간을 일관되게 지정합니다. 사용자에게 표시되는 값과 구조화된 값 사이의 날짜(및 선택적 시간 및 시간대)가 일치하는지 확인합니다. 시간 및 시간대는 구조화된 데이터에 제공되었더라도 사용자에게 표시되는 데이터에서는 선택사항입니다.
향후 날짜 또는 페이지에 설명된 작업 날짜는 지정하지 않도록 합니다.
날짜는 페이지의 게시 또는 업데이트 날짜를 설명하지만, 여기에 설명된 스토리나 이벤트는 설명하지 않아야 합니다. 원하는 경우 페이지에 이벤트 마크업을 추가하여 페이지에 나열된 활동을 설명할 수 있습니다.
페이지에서 다른 날짜 표시는 최소화합니다. 권장사항을 따랐는데도 잘못된 날짜가 선택된다면 페이지에 표시되는 다른 날짜를 일부 또는 전부 삭제해 보세요.

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)."]]
