What Can You Get out of It (Benefits)?
On your landing pages, you're interested in how many downloads they contribute to, how many page views they achieve, and how they generally succeed in piquing the interest of your contacts. The relevant metrics can also tell you how often visitors leave their email address on a particular landing page.
Another important metric related to landing pages is bounce rate: how many of your visitors leave the landing page without filling out your form? A high bounce rate often means that visitors didn't feel addressed by the content on your landing page or didn't understand it.
