Page Descriptions needed on Hide from Search Pages?

Site URL: https://www.etailmaven.com/

Hi, 

I am using index pages to organize the content on my site (Brine - Mojave template) and I have followed the recommendations to set the sub pages to 'hide from search' since it's the index pages that I want visitors to land on.  If these sub pages are hidden from search do they still need optimized page descriptions or does it not matter at all for SEO.  The page descriptions do not show up on my site so they are not important in that respect.

Thank you in advance for any insight.

I would still do them if I were using a search box for searching the website. 

Hi @ArtByPino,

I don't have an on site search.  So, you wouldn't do them then?

Thanks
