Hi Tim,
Thanks for contacting us. :)
There are several= reasons an optin's impression data does not match
your overall pagevi= ew count in Google Analytics, including:
* ORDER OF OPTIN LOADIN= G: if you have multiple optins of the same
type they will load on the= page in the order they're embedded in the
DOM. If for some reason the= visitor never proceeds through the first
optin that appears of that t= ype they will not end up viewing any
additional optins of that type un= til they do.
For example, assuming you have three lightbox optins embe= dded
throughout your entire site:
- SCENARIO 1: The homepage is set= to load all of the optins. Optin 1
appears to the visitor but they ex= it the page before loading Optin 2
and Optin 3.
- SCENARIO 2: Optin= 1's page targeting excludes the optin from
loading on the homepage, a= s a result Optin 2 loads on the homepage
first and there's no impressi= on counted for Optin 1 on this pageview.
* COOKIE SETTINGS: OptinMo= nster allows you to set both _Individual
Cookies_ and _Global Cookies_= to help control how often your optins
appear to visitors.
- INDIVI= DUAL COOKIES: Once a visitor has successfully subscribed, or
closed th= e optin with the close icon, a cookie will be set for the
number of da= ys you've specified. Once that time has lapsed the optin
will appear t= o them again.
- GLOBAL COOKIES: What this does is prevent any popup o= ptins from
appearing to a visitor only once they've successfully subsc= ribed
through one of your optins. If they close the optin with the clo= se
icon the Global Cookie will not be set, only if they subscribe. Thi= s
allows you to more finely tune the appearance of the optin to your=
visitors.
If you've set an individual cookie for any optin and t= he visitor
closes or submits the optin they won't continue to see that= optin even
if they continue clicking through your site and generating= pageview in
Google Analytics. If you've set a global cookie for the d= omain and the
visitor closes or submits an optin they will not see any= other optins
on the site until the cookie duration has passed or they= clear their
browser's cookies.

[1] * DESKTOP VS. MOBILE: There= are two optin types that load on
Mobile devices, Mobile [2] and Fulls= creen [3]. Both of these are
available only with a Pro license subscri= ption [4]. You'll want to be
sure you're filtering your overall Google= Analytics pageviews by the
device used and compare to mobile vs. non-= mobile opt
