Hello,
Thank you for reaching out and bringing your concern to our attention.
I’m not quite sure whether I fully understand the question. But I’ll do my best and please let me know if I still misunderstood.
Can you please confirm if you wish to automatically insert an info from Google SERP into the Rank Math meta description? If so, this isn’t possible at the moment as you can only specify the meta description on the plugin alone.
If it seems that I am still missing something. Kindly explain your goal in detail and please share some examples or screenshots.
Looking forward to helping you with this one.

If i have a post title rank math, it would be good if I can collect the google keywords in the bottom as my meta desc
Hello,
Unfortunately, at the moment it is not possible in our plugin but for your keywords, you can use our Content AI features. For more details, you can check this URL: https://rankmath.com/kb/how-to-use-content-ai/#keywords
