With the conclusion of the Terian Adwords campaign on April 1st, I can confidently say: it was a waste of money.
Yes, that’s right, not a single copy of either ID Creator, or Image Capture Pro was purchased during the time-frame of 1st Dec 2014 til 1st April 2015. In fact not a single sales enquiry was received via the website (and I have checked multiple times to ensure it is working correctly).
Whilst it would have been nice to have a single copy purchased, I feel it would be more important to receive any form of enquiry regarding the product, as that would at least help validate that web based marketing could potentially work.
While web traffic certainly increased, this is merely a vanity metric, especially when taking into account not a single enquiry was received.
Future marketing will be done via different channels, and while I can see how Adwords can benefit some people, continuing to utilise it in its current form would be a waste of money. So that is my Adwords experiment for ID Creator, and Image Capture Pro is finished (for now).
