A few other things I can think of:
• If a recent update maybe it’s just time to propagate • Publish status of the blog post • Is there a sitemap to crawl the site? You can manually ask Google console to crawl again right - might fix it with a request?

Maybe https://pingler.com/ could help to reindex content faster? I use it, but not sure how effectively.

Yeah, sitemap exists and the posts are from last year. Have to check the the index date. Maybe just update some to test

If the meta description is not relevant to the search query, or if it’s too long/short, then Google may decide not to show it. Also, Google may not have crawled the meta description. Try doing a URL inspection on Google Search Console and request a recrawl.

Thx Roberto Robles. That’s a good idea. I’ll try optimizing the description and requesting a recrawl.
