Ask HN: Dynamically Created Content for Webpages

Hi all,

I've noticed, especially on the homepage of Chrome for mobile where Google recommends webpages, that some of them feature outdated content presented as new. For instance, a product released a year ago is highlighted in a post dated today. Interestingly, these posts often relate to products I've recently viewed on sites like Amazon or eBay.

I'm uncertain whether this content is dynamically generated or if these webpages deliberately post old content to attract customers.

Has anyone observed something similar?
