Final answer:
The statement is generally false; merchants can usually change which products appear on a webpage through the use of content management systems, product tagging, and customization tools provided by e-commerce platforms.
Step-by-step explanation:
The question seems to be related to the customization of product displays on a webpage, which is a common practice in e-commerce and digital marketing. The statement suggests that there is a limitation in changing which products appear on a page. However, this is typically false. Most e-commerce platforms provide tools that allow merchants to control the curation and display of products in their online store. This might involve using content management systems, product tagging, and dynamic widgets that can be tailored based on user behavior, sales trends, inventory levels, and various other criteria decided upon by the vendor or marketing team.
Moreover, for platforms that use algorithms to determine product display, such as online marketplaces, merchants often have the ability to influence their product's visibility through search engine optimization (SEO), advertising, or participating in promotions. Consequently, vendors have multiple avenues to change which products are displayed to customers, whether through direct control or indirect influence.
