[Plugin: W3 total cache] Recent post not showing

Hi, ever since I have started using w3 total cache, every single time I make a new post, it doesn’t get updated on my site. I have to delete the cache manually only then the recent post will show up on my website.

my questions are
-If i delete my cache every time i have to make my post visible on my blog, does it hurt my SEO rankings/index?
-& is there any other way that I can have my posts shown on my website without having to clear my cache every single time cause honestly, it’s quite annoying.

thank you.

P.S. i’m not good with codes.
