Hi there,
Google Shopping Ads is definetely the most effective medium to run ads for party items. Nearly everyone uses Google, Google Shopping Ads Generate 85.3% of Clicks Google Shopping ads make up around 76.4% of retail search ad spend.
So i highly recommend running Google Shopping Ads. It doesn’t have a minimum daily budget, and you can set your cost per click (CPC) as low as $0.01, so you do have a lot of freedom in how much you spend on Google.
Also, Google Shopping Ads also has free listings. All you have to do is set up your Google merchant center account, and you don’t even need a Google ads account.
I would also recommend TikTok Ads and Instagram ads since you might find a lot of your audiences there that are looking for party supplies. You can even get your products up on TikTok shop too.
Let me know if you want to know more about any of the suggestions I shared.
