The ability to create multiple campaigns from one account is great! I like that it's easy for me as someone with limited marketing experience or time management skills to manage my PPC accounts without having to hire additional staff members (or pay them).
There isn't much about Plerty so far but what we have seen has been very helpful in our decision-making process when deciding whether to continue using their services versus other companies out there - they are definitely worth considering if your budget allows!! We use plery primarily because its convenient & affordable compared to larger competitors such as Google Ads 360/AdWords etc..
