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?
So, as with so many answers in SEO: *it depends.*
If you have any specific examples, I'd be happy to take a look! Feel free to message me here on Clarity.
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! :)
There are different ideas on this. Google read your page mainly through your HTML code, so if you view the source code of the page and the content is visible in text form, then you're in good shape.
There are different opinions on how much Google takes into account expanding accordion and tab-like structures where the content is hidden but also fairly accessible to the user.
Even though this is from 2014, it does state that there is a fair amount of discounting going on - https://www.seroundtable.com/google-hidden-tab-content-seo-19489.html
