On some webpages, bits of content can change on a page reload. Some examples of this include client testimonials, or featured images.
When a search engine is crawling your website for content, it only grabs information it sees in that snapshot of time. It would not know if a piece changes or if it should refresh the site to see more.
So, if you have links or content that you want the search engine spiders to find, it is best practice to include them on the site at all times rather than being hidden or changing on page reloads.
