What to do when the website is not updated new article?

What should I do if my website can not post new updates? So what need to hold top keywords Seo?
Thank you

What has the seo part to do with the first part of the post?

I think you need to post more information about your website; is it a CMS ( wordpress type ) site.

Why can it not post updates; do you get an error? How to you add posts?
