Podcasts are a fairly inexpensive way to boost traffic to a website or to advertise a business. The only catch is that podcasts have to be marketed right in order to attract any interest. Just because the podcast exists does not mean that someone is willing to pay for it or spend time downloading it for free. Generally, the topic has to be interesting and by a known personality.
Foraging is an interest that does appeal to some people. They like to camp out and glean some of their greens from the trail or else they are interested in survival knowledge for an EMP or a zombie apocalypse. Either way, a foraging podcast is one type of audio file that some people would listen to. The remaining challenge is finding a survivalist who is both informative and likable.
If a podcast is going to be featured on a frequently visited platform such as Youtube, there is the potential for an enormous viewership if the show is sought after and entertaining. This is a challenge, but some ordinary people have built successful shows from the ground up with their wit and charm. On the other hand, there are also podcasts of exceptional quality that receive very few views because of the technical content and the limited interest from advertisers.
To use a podcast to direct traffic to a product page, the show has to receive a decent viewership. This is especially true if the click through rate for the links are a low percentage. Keeping the traffic coming means having a good show. Sometimes the personality comes up with most of the ideas, but it is also great to have professional marketers who can figure out ways to improve the popularity of a site.
Advertising can boost traffic initially, but the people who initially visit a podcast have to be sold on it so that they keep coming back. This means entertaining them at the same time that they receive useful information. That means employing wit, humor, and a likable personality to keep people returning.
Podcasts are a fairly easy way to attract customers because they are relatively low budget shows. That said, overlaying an audio file with photos of plants would be a great way to format a foraging podcast. People who hear about plants generally want some type of visual, and this actually might compel them to buy books that help to identify plants. To that end, work with a company that can hire great voice actors, develop the material, and finishing the file with editing software.
