I am seeking a solution to customize this "footer ad code" so that it only appears for unique visitors to my blog and does not reappear if the visitor has previously closed it. In essence, once a visitor closes this footer ad on one page of my website, it should not display again when they navigate to another blog post or page within the same site.
<style>
.Arpian-ads {

width: 100%;
min-height: 70px;
max-height: 90px; /* Modify based on your design */
