Learn English – Verb for being part of a team

Perhaps the word you want is drive.

I'm guessing that you want something other than "increasing the sales" or "promoting the product", both of which are good straightforward answers.

If you're looking for a professional vocabulary, as opposed to ad copy like growing a love for fertilizer or creating an appetite for chicken nuggets, here's something to consider:

An increase in sales comes from action by the seller, who naturally wants to get the best return on their marketing and communications investment. There's also something called the McKinsey Consumer Decision Journey and the Loyalty Loop, which many people see as a useful model for encouraging repeat business. A consumer can be reached at multiple points, and at each point the possibility exists of encouraging them to spend more. The right word for your purpose of increasing sales will depend on how the seller imagines the potential customer, how they are being reached, and where they are on their individual journey.

The word you want may be a specific term related to one or more of the following general ideas: You can attract and inform potential buyers. You can help them decide. You can draw them into your loyalty loop. You can reward them for influencing others.

But in the end, if you're hoping to get paid, you need to drive sales.
