Weird problems with google's rich snippet markup

[s-s]

Once upon a time, our site was ranking well and had all the markups showing up in the results. We than lost some of our rankings due to dropped links and not so well kept maintenance.

Now, we are gaining up the rankings again, but the markups don't show up in the organic search results.

When we Google site:oursite.com, the markups show up, but not in the organic search.

There are no manual actions against our site.

any idea why this would happen?

I'm afraid it is the obvious. Ensure the rich snippets are relevant to the content of the page, ensure that your page is ranking for relevant queries to raise the chance of the rich snippet being shown.

what could I do in order to "trigger" the rich snippets to be shown again?

Besides the obvious, content and such.

Thanks

Google only shows rich snippets when it thinks it will be useful to the searcher.

As you have said you have had some issues with maintenance, check the structured data against Google's structured data testing tool. However it is more likely that Google isn't showing the rich snippets because it believes your page quality to be low or that the structured data is not relevant to the user's query.
