If I'm currently using CPV Lab to track my campaigns, will I get any additional data dropping a Google Conversion Pixel that a software like Lab doesn't provide?
Not really.
You can get bounce rate, time on page, referrer data and so on - but these are easily supplied by other systems as well.
For most affiliate campaigns using paid traffic, GA is an unnecessary addition.
Stuff like this makes sense if you go a bit crazy on the email Marketing side of things, for example.
For a Client Project, we used Kissmetrics (which I guess now has been bought by Google?) for advanced user tracking. Because you can basically follow the complete history of movements PER USER on a page, you can do fancy things such as:
- filter all People who saw the sales page, stayed for more than 2 mins (= reading stuff), but did not buy: => mail them a better offer.
- filter all People who clicked on the sales link but did not actually buy: => send them an email asking why thy did not complete the purchase.
etc.... you get the idea.
For affiliate Marketing as discussed mostly over here: I agree with Zeno.
Ok, so what are the downsides to using G Analytics vs. CPV Lab or one of the other popular paid platforms?
@es351045 - it's more of a pain to set up for affiliate needs (MUCH more if you don't control your own offer) and it's less accurate.
