How much time does Google take to display rich snippet of a web page? [duplicate]

Question

I have put some Event rich snippet on the web page, and Google has already crawled this page(as I knew it from the Google Cached Timing of this page), but Google is now showing the Event Rich Snippet.

Although when I have tested this page on Structure data testing tool, I found no error there.

So, I want to know that does Google take some time to display the rich snippet after crawling a web page?

Could anybody help me to find out what is the problem with this page, so that the Rich Snippet is not being displayed properly on Google Search.

Answer 1

If your looking a for a approximate timeframe your going to be disappointed, there is no such timeframe and varies from site to site. Generally it takes anywhere between 2-12 weeks depending on the many factors. It should also be noted that Google can decide 'NOT' to display your rich data in search results.

Having Rich Data on your website isn't always a golden ticket to richer search results, it varies from site to site, and niche to niche.

Q: How long does it take for rich snippets to be visible? A: Once you've marked up your site's content, Google will discover it the next time we crawl your site (although it may take some time for rich snippets to appear in search results, if we do choose to display rich snippets for your site). If you're marking up your content for rich snippets, you can let us know. Google won't be able to individually reply to your message, but we may use the information you supply to improve our detection and display of marked-up content.
