What is the difference between campaigns for posts and campaigns for comments?
Adcomment's knowledge base
Social media posts are best suited for brand awareness and spreading the word about your page, website or business. We recommend this type of campaign to start-ups and advertisers that want their product or offer to get exposure on social media.
Social media comments offer highly targeted exposure to your website or business because you choose the social media post which will receive the replies, and is best suited for advertisers that want clients and conversions.
In the end it all comes down to your needs. If you need to get known and let the world know about your brand or product you should create a campaign for posts.
On the other side if you are interested in acquiring clients, customers or conversions you should create a campaign for comments.
