Hi,
Removing the Date Snippet does not remove it from a Google Search. We recommend, instead, that you enable the “Date in Snippet Preview” feature for your posts under “SEO > Search Appearance > Content Types” as this makes sure the description doesn’t exceed the maximum length.
We also know that Google uses the datepublished structured data Yoast outputs as one signal to determine if it should show the date. This guide explains more: https://webmasters.googleblog.com/2019/03/help-google-search-know-best-date-for.html. Unfortunately, Yoast does not have a feature which removes that piece of structured data.
The only workaround is to use our filters here https://developer.yoast.com/features/schema/api/#add-or-remove-graph-pieces to remove that data. Bear in mind that removing this will generate a warning in the Google Structured Data Tool: The dateModified field is recommended. Please provide a value if available.
Unfortunately, there’s a difference between the support we can offer and the level of programming needed to change (core) features of our plugin. Since we don’t want to take the risk that we break your website by suggesting incorrect or incomplete code, we cannot advise you on how to make such changes. And even though we cannot be of any assistance, you’re completely free to change anything in the plugin to better suit your needs.
If needed, we highly recommend checking out the Yoast supported partners here: https://yoast.com/yoast-partners/.
Note, that we will keep this topic open for 1 week in case a member of the community is able to provide additional help. After which we will close it to keep the overview.
Once you have removed the date, if you only have a few pages try using Inspect Any URL on the page. This guide explains more: https://kb.yoast.com/article/108-fetch-as-googlebot. This will force Google to reindex the page and hopefully the date will disappear from Google’s index. If you have a large site, you may need to resubmit your sitemap.
