Hello,
We apologize for the inconvenience you’re experiencing. Unfortunately, it’s not possible for Rank Math or any other SEO plugin to directly add or remove dates from search engine results pages. However, you can work around this by removing dates from the places search engines look for them. If search engines cannot find your dates, they cannot display them in search results.
You can start by removing the dates from your content, WordPress settings, themes, plugins, and structured data. We have a detailed guide on how to remove dates from WordPress posts and URLs here.
If you have Rank Math installed, you can use a filter to remove the date properties from your structured data. You can find more information on adding filters to your website in our knowledgebase article here.
We hope this helps! If you have any further questions or need assistance with this process, please feel free to ask.
