This may be a bit advanced for some, but just a warning: the problem with Google Analytics Event Tracking is that it is not a completely accurate way for tracking unique pageviews, as it wasn't built for that (it was built to record visitor's actions such as hitting play on a video or downloading a file). So the code above, while semi-helpful, is not an entirely accurate way of recording unique pageviews and probably should not be 100% used to determine pay for bloggers.

The reason Event Tracking is not accurate for tracking pageviews using the code above is that if a visitor views multiple unique webpages in WordPress's "Single Page" view (single.php), Event Tracking will only count those views as 1 unique event (or 1 pageview). For example, say a visitor reads one article, then reads 10 more on your site, Google Event Tracking will record all those views as 1 unique event, and also record it as 11 total events. (You'll have to read up on Google Event Tracking to know the difference between Total and Unique Events.)

Why does it do that? Because "Single Page" (single.php) is the trigger, not individual post titles. So even though a user is browsing multiple articles on the site, Google Analytics Events Tracking only counts it as one unique event of accessing the single.php on your site during the visitor's session. Think of it the same way regular ol' Google Analytics counts unique pageviews, except instead of a tracking a specific URL, single.php is the webpage, and the posts are just the dynamic content loading inside of it.

So to reiterate, no matter if a user reads 1 article or 11 different articles in "Single Page" view, it will only be counted as 1 unique event during a user's session on your site,

So Total Events seems more accurate right? Wrong. Because if that same user views the same article 11 times (in other words, hits refresh 11 times), it will count as 11 total events, also ruining your pageview counting.

So unique events does not equal unique pageviews. And that's too bad, because unique pageviews would be one accurate way to measure individual author success on a multi-author blog.

Maybe there is a way to do use Google Analytics Event Tracking more accurately than the above code example, I'm still looking for it though.
