When I launched my venture MeriCAR. com on an idea that didn’t exist in India but got few searches on Google given me enough links for similar idea in another country.
Even if it exists, you still can not COPY because your strength and capabilities VARIES. For example, my idea is still different in another country because of DIFFERENT Behaviour of Target Customer.
What will work in USA today has no link if it work here in the same way.
Even the competitor’s strength varies. Tech-founder will try to build SAME thing always DIFFERENT than CFO as founder. There will be always difference of doing between two competitor.
Google is still a large search engine. You just need to know about your subject very well to play around ”keywords”.
