16 tools for Reddit Ads: performance by community and placement, subreddit research, Reddit's own bid suggestions, and the everyday controls (status, budgets, bids, targeting, and account-wide exclusions).
Read tools are always available. The five write tools are off until you allow changes for Reddit, and each one shows you a preview before anything changes. Budget changes stay inside your workspace's budget-change limit, and the preview warns when a change is big enough to reset Reddit's learning.
Sample prompts
"Which communities drove the cheapest conversions last month? Which ones only burned budget?"
"Find subreddits about home espresso we're not targeting yet."
"What does Reddit suggest bidding on this ad group?"
"Exclude these five communities from every campaign for brand safety."
