If you are really adding some actual value then $5 is a price point that would make me dismiss your product offhand because the price is too low. Is there a gap in perception of value or is there just little value in what you are providing?
No. I might like to pay for intelligence on GA if I knew anything about what was being offered. If you want more accurate answers, you're going to need to share more details.
I would pay >$100/mo for something that has intelligence. If you could create an AI to replace a junior marketing analyst, it's worth it. But you have to first talk with businesses and really understand what kind of intelligence they need.
No, GA provides a variety of reporting options and formats - from simple to complex - out of the box, it has an active expert community, and its best practices are very well-documented.
