@JCP Vlemmix,

Thx for your reply. I does however not entirely anwer my question.

To my information Google may include the date in the snippet on the SERP. The date used can be the crawldate or a date mentioned on the webpage. I am not exactly sure how to influence the date shown in the snippet.

I have pages that were created long time ago and are update regularly, by me and user comments. I would like this page to carry a recent date that is shown in the snippet on the SERP.

For know I am going to run a test on a few pages in which I show the date on the webpage in a USA date format. If Google picks up this date i conitnue testing with updating this date on the webpage everytime the webpage is updated. How do you manage the date in the snippet?

I have a website with sauna reviews. These are mostly pages that exist for years and regularly change because comments/reviews are added by visitors and/or because I change information on the page.

When searching in Google for competitive keywords I noticed that the snippet of my direct competitor included a date stamp in the format (9 hous ago).

How can I include a time stamp in the snippet, and more important how can I make sure that the timestamp is very recent.

Is it sufficient to add a date on the page every time the page is updated or is ther emore to it?
