You can read more Facebook advertising policies to understand better. Usually, we advise customers not to use images of fat people or discrimination. Do not use words with guarantees or commitments in Creatives, but only state product content as supporting and not a substitute for medicine. This is the case for using strong accounts and having applied Cloaking, so that is all that is needed; however, if you have a new account, you need to be more careful.
With Nutra, you should start with broad targeting (age, gender suitable for the product), limiting too many interests. Meta currently optimizes better with machine learning. Then use retargeting (view content, add to cart) to increase conversions. Demographics and interests should only be used for initial direction and should not be relied upon too much.
3. Nutra is a sensitive niche on Facebook, so sometimes Facebook will lock accounts for no reason. When running BH&GH niche, the risk most encountered is account locking. You should find accounts that already have a spending history and long-term activity to reduce risk.
You create a bait campaign with a low budget of $10-20 to warm up and create the main campaigns (leave them in a turned-off state). Then after about 3-4 days, if the bait campaign is spending steadily, you turn on your main campaigns. If during the process any campaign converts well, you gradually turn off the remaining campaigns.
You install Pixel to track and increase conversions for the campaign. If in the first week conversions are low, change to another Pixel. Keep doing that until there are conversions; that is the suitable Pixel for your campaign.
