Welcome to podcast Maps. My name is Graham brown. I'm going to share with you five insights from the world of audio, very different insights from tech, business and society. This week, we're going to look at what Instagram is doing in audio and what that means to Facebook, Tik Tok and Spotify. 

Then we're going to look at podcast rankings and data analytics. I'll offer some insight into three rankings apps that are available on the market right now being Chartable, Rephonic and Podstatus. Then we're going to look at an app that I've started using recently, which isn't actually a podcast app, but it is audio journalism. It's called Curio. I'm a big fan, I'm now a subscriber of the app and I think you should check it out at least to see what's possible in audio. 

We will then finish up with two disruptive trends. The first one is Neil Patel, the SEO guru, moving from guest posting which he has been using as the cornerstone of his SEO content marketing and thought leadership strategy for so long and now doubling down on podcast guests. Lastly, we'll look at the podcast $150 billion opportunity. Everybody talks about podcasts in terms of advertising. But i feel that there's a large untapped and overseen opportunity in podcasts. All this and a lot more coming up in this week's episodes or podcast maps. Enjoy the show.
