Hi Rama,
1. Please let me know what are Search, Social and Display.
In short,
Search Advertising: Placing your ad in the sponsored section of a search engine listing
Display Advertising: Placing your ad/Banner in the ad sections of particular websites
Social Advertising: Placing your ad on social media networks like Facebook, LinkedIN etc
There is a plethora of content around all these topics over the web, I would recommend going through the available articles to get a good understanding of all the three.
2. Does AMO work for Targeting Websites and Mobile as well?
If you mean targeting particular websites for advertising your ads, yes you can do that.
3. Does AMO work for Targeting offline channels like Email, SMS, Push and Call Center?
No
4. Adobe Campaign also does some of these. What is the difference between Campaign
Adobe Campaign is a solution for Email and SMS marketing. It can also design landing pages. Campaign does not do any kind of search, display or social marketing, AMO is the solution for that.
I hope this helps.
