Gloria has a coffee shop and has been in business for years. She has many customers that are regulars, but she's looking to acquire more. So far, she has signs around the neighborhood, a TV commercial, an ad in the newspaper, and coupons sent to everyone in the area. Which form of advertising can she utilize now that she hasn't already?

One form of advertising that Gloria can utilize now is digital marketing. She can create a website for her coffee shop and optimize it for search engines to attract new customers who are looking for coffee shops in the area. Additionally, she can utilize social media platforms like Facebook, Instagram, and Twitter to promote her coffee shop, engage with customers, and run targeted ad campaigns. Another option is email marketing, where she can collect customer email addresses and send newsletters or promotional offers to keep them engaged and encourage repeat business.
