I might be wrong but can you put their ad on your blog without the sponsorship?
I have a travel website where I put google ads. I post about our RV trips and RV related ads pop up, same with the Cambodian trip, Thai and Cambodian companies show. All how Google makes them (and me) money.
2008 Itasca Sunova 35J Class A
1997 TJ Sahara, hard and soft tops and AC
Held together via Roadmaster Falcon 2 tow bar and stopped by US Gear Unified Brake system.
We have added those ads to our you tube page and are thinking of adding them to our blog as well. We are always open for ways to make money and keep ourselves RVing! What is your blog, I would love to follow you.
