Grow Your Podcast with Cross-Promotion
Use CastFox to find partner podcasts with overlapping audiences, compare performance data, and build cross-promotion campaigns that grow both shows.
Why Cross-Promotion?
Cross-promotion is one of the most effective, low-cost strategies for podcast growth. Partner with complementary shows to reach new listeners who are already podcast fans.
Low Cost, High ROI
Cross-promotion costs nothing but time. You exchange exposure with a partner show, meaning both sides grow without spending a dollar on ads.
Audience Trust
When a host recommends your show, their listeners trust the endorsement. This warm introduction converts far better than cold advertising.
Mutual Growth
Both podcasts benefit equally. You gain new subscribers from their audience while they gain from yours, creating a true win-win partnership.

Cross-Promotion Strategies That Work
Once you find your ideal partner, choose from proven cross-promotion formats to maximize listener growth for both shows.
Guest Swaps
Appear as a guest on your partner's show while they appear on yours. Both audiences hear directly from the other host, building trust and curiosity to subscribe.
Promo Spots
Record short 30-60 second promotional clips for each other's shows. Insert them into episodes as pre-roll, mid-roll, or post-roll spots for continuous exposure.
Joint Episodes
Co-produce a special episode together and publish it on both feeds. Shared content gives listeners a taste of both shows and drives subscriptions in both directions.
Shared Content
Collaborate on social media posts, newsletter mentions, or blog features. Cross-promote across all channels to extend reach beyond just audio.
