TikTok operates similarly to other advertising platforms such as Facebook and Google in that it allows businesses to create and run ad campaigns to reach a specific target audience. However, there are some differences in the way TikTok operates compared to these platforms.

To set up cost per impression (CPM) bidding on TikTok, you will need to create an ad account, set up a campaign, and select CPM bidding as your preferred bidding method. Once you have set up your campaign, you can set a target CPM for your ads, which is the average amount you would like to pay for each thousand impressions.

As for Shopify integration, there is currently no automatic integration between Shopify and TikTok, but you can manually link your TikTok ad account to your Shopify store and create campaigns that promote your products.

It’s important to note that TikTok is a relatively new platform for advertising, and the way it operates may change over time as the platform evolves. It may be helpful to consult with a marketing or advertising professional to determine the best approach for your business on TikTok.
