Having an industry influencer publish a blog post on your site or turning an interview with them into a blog post can help to drive traffic both through organic search but also via that influencer promoting the content to their audience (see the backlinks section above). This can also help to add more variety to your content and show your visitors that you are active in your field.
They often expect you to commit to working a certain number of hours per week, which is generally part-time. They will pay you an hourly salary for that work, so it is really more of an at home job situation than it is in an entrepreneurial way to make money online. Still, if you want to get involved in political activity, and you have the time and motivation, this could be a way to monetize that passion.
