It’s never been easier to test market anything in the history of startups. The web is our best friend for testing regardless of which market we compete in, or are launching into.
How would we do it? There are many simnple methods:
– Google adwords testing various ideas to see which ones get clicked on the most
– Build a landing page for a certain product idea to see how many hits it gets
– Set up a ‘coming soon’ registration facility to assess market interest and ask the punters what they’d pay for such a service / product.
– Tweet our idea for feedback (which is what I did for www.startupschool.com.au) before the launch to assess interest)
– Start a facebooks fans page for a non-existing thing / service or idea that you’ll build afterwards.
– Start a blog on the topic and see how many followers and participators we get to see if there is market support.
How will you pressure test your next startup idea?

Nice list!
“Start a facebooks fans page for a non-existing thing / service or idea that you’ll build afterwards.” That’s actually what I’m doing for a little side project I thought of building and running – set up a Facebook page and watching the traction http://www.facebook.com/pages/Christians-in-Business/130335033649621 – with barely any real involvement apart from a video message. Looks like a dedicated website will be coming soon.
