By doing research with actual humans and finding out what people actually search on. My family business is renting out portable sleepouts. They get called "cabins" which is really an Americanism and not a local word at all. The franchise in a popular holiday destination struggles - because "cabin" is used by campgrounds to describe the small huts they rent out on site. So nationally we might see a certain about of traffic for the word "cabin", we know that it's a keyword that could describe our service and be fooled into thinking that it's a good word to optimise for. By talking to our actual customers we can weed out the keywords that look good but aren't used for the niche that we actually operate in. After all, why waste time and money on keywords that may result in phone calls that will waste more time and money while we explain that what we do isn't what they want.
