The indisputable advantage of agency ad accounts is the loyalty of the site. In controversial situations, Facebook will be sympathetic to your issue.
However, the situation differs with self-registered accounts — stress will accompany you. You don't have to go far to get examples: those who place ads and redirect users to the advertiser's goods/ services get banned often for Policy or Risk Payment.
- Policy compliance — violations of the site's own advertising rules;
- Community standards for fan pages — when zero activity is questioned by the algorithms;
- Creatives specs — when non-unique creatives are uploaded;
- Triggers — n this case, the text and creative have a conflict with the FB appeals and elements (for example — «How to make money fast?» «Slim down for free in three days» etc.).
Similar restrictions may apply to gray goods and services, such as gambling, dating, adult websites, microcredit, etc. Even white niches may encounter challenges due to tightened moderation by the social network.
Therefore, if you're considering whether it's worth paying for an agency's ad account, our answer is a resounding yes! Effective advertising on Facebook without losing money or stress is about something other than self-registered accounts.
