Online paid advertising is becoming an increasingly competitive field and being profitable is no longer as simple as it used to be. One way around this it to find complementary products which share the same market with you, and run shared ads to lower your ad spend and increase your reach.
You can find ads partners by reaching out to complementary companies you know.
I find the idea of bundling campaigns with complementary products interesting. However, on mainstream advertising platforms, the bidding platform typically decides how to allocate bidding chances to different campaigns based on bid price and metrics like CTR, viewability, and CVR. Given that companies usually evaluate these metrics based on the match between context and ads, how can we ensure that bundling our campaign with complementary products still leads to a fair allocation of bidding chances between our product and the complementary product under such platforms? Would a unified bidding price be suitable for both of your campaigns? How can we ensure that the expected outcomes are achieved despite the platform's control over the bidding process?
Good strategy.
I would need to try it and see if it works, I guess will be challenging at the beginning to identify correctly the complementary products.
Newsletter advertising is a good strategy for reaching new audiences as well. You can locate partners through ad exchange platforms or direct outreach. Keep an eye out when reading your favorite newsletters, sometimes you'll find a link to learn about sponsorship options.
