Q: Do you think $100 to $400 is enough to run a successful PPC campaign?
A: There are many variables missing with your question, which make it tough to gauge where you are with PPC.
I don’t know if that budget for you is daily, weekly, monthly, or some other period of time.
Also, it depends on how you define success. In my view, a positive return on investment for a PPC campaign is a success, but certainly I’d refer a 300% return over a 110% return.
So that ties into your ultimate goal. Do you want this to be a full-time job for you, or a hobby that nets you a few hundred dollars a month?
I would suggest that you start testing with a modest investment to get a feel for what works and play around with the systems a bit.
And then, just keep scaling up so long as it is profitable.
You could easily spend $400 a day with PPC, and if it’s returning a profit for you, that’s great.
You could do the same with $1,000 or $5,000 a day. It all comes down to whether you’re seeing positive returns, and perhaps how risk averse you are as you try to scale it.
