With a plugin, I added "reading time" to each article i.e. how long it takes to read the article.
How might I pull this value into GA for each URL?
I'd like to compare how long people are on the page against how long it should take to read the whole article.
I understand I need to add a key to the data layer, and pull that key into GTM. I'm not sure how to create a custom key to add to data layer.
I need to do the same thing for a thumbs up feedback button I'll be placing on my articles.
Anyone have experience with this sort of thing?
Thanks!
