As of my last update in September 2021, TikTok's ad manager platform might have evolved. However, I can provide you with general steps on how to work on a TikTok ad manager account. Please note that some specific details might have changed, so it's essential to refer to the latest resources provided by TikTok.


1. **Create a TikTok Ad Account:** If you don't already have a TikTok ad manager account, you'll need to sign up for one. Go to TikTok for Business website (https://ads.tiktok.com/), click on "Create an Ad" or "Get Started," and follow the instructions to set up your account.


2. **Ad Campaign Objective:** Once your account is set up, decide on the objective of your advertising campaign. TikTok offers various campaign objectives like reach, traffic, app installs, video views, etc. Select the one that aligns with your advertising goals.


3. **Campaign Creation:** Start by creating a new campaign. Provide relevant details such as campaign name, target audience, budget, schedule, and bid strategy. You'll also need to select your target audience based on factors like location, interests, demographics, etc.


4. **Ad Group and Creative:** Within your campaign, you'll create ad groups. Each ad group will have its targeting parameters, but they'll share the same budget and schedule. Decide on your ad formats (e.g., in-feed ads, branded hashtag challenges, branded effects, etc.) and upload the creative assets (images, videos, ad copy) for your ads.


5. **Budget and Bidding:** Set a daily or lifetime budget for your campaign. You can also choose how you want to bid for ad placements - cost per click (CPC) or cost per impression (CPM).


6. **Review and Launch:** Review all your campaign settings to ensure everything is set up correctly. Once you're satisfied, launch your campaign.


7. **Monitoring and Optimization:** After your campaign goes live, closely monitor its performance through the TikTok ad manager dashboard. Keep track of key metrics like impressions, clicks, conversions, and return on investment (ROI). Based on the results, you might need to make adjustments to your targeting, creative, or budget to optimize your campaign.


8. **Reporting and Analysis:** TikTok's ad manager provides detailed analytics and performance reports. Analyze these reports regularly to gain insights into your campaign's success and identify areas for improvement.


9. **Experimentation:** Don't be afraid to experiment with different ad formats, creative styles, and targeting options to see what works best for your brand or business.


Keep in mind that TikTok's ad platform might have additional features and changes beyond my knowledge cutoff date. Therefore, I recommend referring to TikTok's official resources and help center for the most up-to-date information and step-by-step guides on using their ad manager.
