Dive Brief: 

• Reddit is expanding its AdWords-like self-serve ad platform to be more accessible to small- to medium-sized businesses. 
• The pitch to small businesses centers on the "subreddits" — sections of the site with threads focused on specific or niche topics. 
• SMBs can buy in for as little as $5 with a CPM of $0.75 while still having hyper-targeted ad options. 

Dive Insight: 

Marketers have long lusted after Reddit's 17 million unique monthly page views. The site's users of are passionate, loyal, and strongly opinionated — especially about how ads are shown to them. For that reason, it makes sense for any interested brand to approach the site through Reddit's own platform rather than attempting organic reach. Since the site is opening up possibilities to SMBs with low costs, more brands will have that opportunity.
