How do you get 16,444 Google Search Network Adwords Clicks for $4,776 dollars? Try new things when the price is right, usually when they are first coming out before everyone piles on.
I created a web based groupware platform in 2001 and operated it until 2009. Trying out Google Adwords early in 2003, I was able to get the best prices. At the time I wasn't really aware of the bargain click prices, I just wanted to advertise my web collaboration product.
I was determined to bootstrap this product and do everything myself from programming, sales, to marketing. I spent about $8 a day on Google Ads, I entered into some web 2.0 contests, and had good word of mouth. This equaled into about 50,000 organizations signing up but I just kept programming and programming... stuffing more features into the system rather then really defining a good workflow and how to use the system beyond collaboration. One large missing feature is that while you could add a file, forum, or calendar to a sharing group you had to go to each module to see that modules data.
I have recently started to re-work the interface, workflow, and inter-connectiveness of the data across modules. Once finished with the programming I will seek out funding for marketing and sales.
