Yes and No.
Whether to use Google ads for new products depends on if people are searching on Google for problems that your product solves.
People views your ads on Google when they are searching for something. Hence, Google ads are effective only when someone is searching for a product or problems that the product solves.
Let’s understand this with an example:
If people are looking for ‘plumbers near me’ and if you are offering plumbing service as a new plumber, yes Google ads will work for you.
But if you have a product that solves a problem for which there is no Google searches, Google ads will not work for you.
Now to get reliable data on how many people are searching for a keyword (your new product), you can go to Google keywords planner and enter the basic product related keywords or competitor brand keywords.
