Digital marketing on Reddit involves using the platform to promote products or services, engage with the community, and drive website traffic. There are a few different ways to approach digital marketing on Reddit, including:

1. Posting in relevant subreddits: Find subreddits that are related to your product or service, and post content that would be of interest to the community.

2. Running ads: Reddit offers a self-serve advertising platform that allows you to target specific communities and demographics.

3. Hosting AMAs (Ask Me Anything): Hosting an AMA can be a great way to connect with the Reddit community and position yourself or your brand as an expert in your field.

4. Collaborating with Reddit influencers: Reach out to popular Reddit users and see if they would be willing to promote your product or service to their followers.

It is important to remember that Reddit is a community-driven platform and its audience is highly engaged, therefore it is important to be authentic and provide value to the community rather than just promoting your product or service.
