100 KWs. Ain't one problem.
Write down the ideal website you want to become. One that you think about "that's us in the future".
Paste the 100 keywords you'd like to start with. Writing them down doesn't mean we will work on them, it just gives us a heads up into what you want to achieve.
Example: My target is 40 year old retired aunties that travel around the US and Mexico wanting to experience the best of food, things to do and places to visit.
