How to setup ecommerce tracking in Google Analytics if ecommerce platform is setup on subdomain?

If the transaction happens on the same website, as the test, you don't need to do anything. The user has a cookie that attributes the version of the test to the revenue tracking in your testing software (Optimizely, VWO). Once you connect the Google Analytics with testing software, you should be OK to go. If this is not the case, then you need to setup two email subscriber lists, one for each version of the test. Then manually tag email links in the emails to attribute the ecommerce revenue directly to the version of the test.

It's isn't just you. Adobe reported that "over $21.8 billion in global ad revenues have been blocked/lost so far in 2015." largely thanks to mass adoption with the AdBlocking software :) 21 million users in 2009, to 198 million active global users as of June 2014-likely overtaking the other comps entirely.

Google Analytics is the best free tool out there for this. Make sure that you are focusing your report on conversions - how many/what percentage of website visitors are taking action (filling out a form, buying a product, etc.). If you're interested in paying for help, you should check out Moz or HubSpot, but Google Analytics is your best free option for web reporting. They also provide some social reporting - which social networks are driving traffic to the site and which network referrals are leading to the most conversions. Good luck!

Yes. While Experiments reporting is session based, a user is kept into the test, seeing the same variation the whole time, so when they convert, they will be attributed to the test variation they have been seeing. This is limited to the same browser on the same device, so if the user changes devices (20% of the time for average eCommerce sites by my estimation) or clears cookies (1%) or changes browsers on the the same device (?), than Experiments (and nothing else legal) can track them. Hope this helps. PS(I suggest you look at other tools, as Experiments is the last tool I would recommend right now).

Being a Google Partner has many benefits, but they revise them all the time. Google seems to protect their intellectual property heavy, so as a partner, you can display their partnership logo to your potential clients. Also, when they roll out new products in beta, you know before the public does. As Google products go, that's a huge benefit. They provide enhanced support when you need it as well. I also do a lot of public speaking, so the one benefit public speakers enjoy is that they let you speak at their events; a very valuable benefit to us public speakers ;) I hope this answers the question.
