Many site templates from E commerce hosts such as Big Commerce have product carousels on the home page.
Does this create confusion when the product titles which are scrolling through this section of the page are constantly changing?
No it does not, search engine crawlers do not see images or videos, but only browse code. You can insert Alt Tags onto images which label the otherwise unseen aspects of your website. I would label the carousel something ambiguous with relevancy to your keywords or I would just stay away from labeling it at all. Hope that helps! :)
