Marketing podcasts is hard!

  • Social ads convert poorly

    Social media users don’t pause to listen to podcasts. They’ll follow you but not listen.

  • Dynamic audio ads miss the mark

    No control where your ad is placed. Listeners will get alienated and skip or ignore it.

  • Partnering is a time suck

    Days of research to vet podcasts to partner with. Then weeks just to place a single ad.

Frequently asked questions

    • Why has Grro not offered me any matches that overlap with my audience?

      Our algorithms rely on specific metrics and criteria for a comprehensive audience analysis of your show. Unfortunately, based on the available data, we don't currently have sufficient information to uncover suitable matches. This often occurs in the early stages of your podcasting journey or if your audience is highly niche.

    • What should I do to increase my chances of getting audience relevant matches?

      As your podcast continues to grow and attracts a diverse audience, your chances of receiving recommendations from Grro also increase. Explore our curated tips to help you expand your audience.

    • What is the minimum criteria for my podcast to get matches that overlap with my audience on Grro?

      There isn’t a minimum requirement that can be quantified in numbers. We use engagement indicators from across the web to understand your audience’s listening habits. Then, our algorithms map this input into connections within the Podcast ecosystem. So, if your podcast does not have enough of these indicators we can’t offer you any matches.

    • What about my download numbers?

      We do not yet collect download numbers to power our match engine. However, later, we intend to collect them to understand the minimum number of listeners required for optimal targeting. The download number will be weighted by other download numbers in your niche. So, 1000 downloads could be good enough in an extremely niche topic space. But, in a popular space this could be more.
