Hey!
I have an elegant solution for you 🙂
Just add a noindex meta tag to the page of your blog post. This is what that will look like:
<meta name=”robots” content=”noindex”>
In most cases it helps. Good luck !
Let me add correction here: previous answer would remove your post from google indexing, but i guess you are looking for a different solution: you need another text to be shown by google.
In this case you would need to ask google to re-index the page.
You may submit it for re-indexing through Google Webmaster Tools (you would need to use Fetch as Google Tool https://www.google.com/webmasters/tools/googlebot-fetch?pli=1 and then click on Submit to Index button).
If you don’t have a GWT account, you may simply add your URL for reindexing through https://www.google.com/webmasters/tools/submit-url
I hope it helps.
Thanks!
