For sure! I think that’s something Jeff and I have learned rather quickly is to definitely not put all your eggs in one basket. We had 1-2 affiliates that we promoted for the longest time that were by and large our main sources of income. We realized that if we lost even 1 of those affiliates we would be in for a huge world of hurt when it came to our monthly intake.
Always disclose your affiliate relationship. Most visitors will probably understand that graphic ads will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.
This means that if someone skips an ad, or is running an ad blocker, then you don’t get paid for that view. This makes estimating the amount of views a video has and how much a user makes off of the video very challenging. It also depends if it’s a video ad at the front of your video, or just a box at the bottom of your page; this determines how many people interact with your ad and the amount of money that can be made.
Ad block software does, in fact, block ads before and after videos. It blocks them on the side bar as well. It will even act as a proxy for tablets and phones to block in-game ads. So, this does really present a problem for YouTubers and others who make money from their content through ads. I used to use them, and I still do outside of youtube to keep malware and annoying ads from pushing themselves into my face. Some of these ads can be malicious.
The great thing about sponsorships is that you don’t have to give YouTube a cut. Plus, you can negotiate whatever contracts you want based on impressions and the size of your audience. In most cases, the amount of revenue you generate from sponsorships is substantially more than YouTube ad revenue. (Meanwhile, you can still generate ad revenue. So it’s like having two sources of income from the same video.)
Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
