Google knows websites change all the time.
For example, you may periodically change the content on your ‘about us’ page or write a brand new blog post every few days.
So they have to constantly re-crawl websites/web pages to look for new content.
This is where internal links come in.
Google relies on internal links to discover new content.
This works because whenever you add a new page/post to your website it’ll almost always be linked-to from somewhere on your website.
