I run a campaign in adwords However it very inconsistent, one day I get 7 sales then very next i get just 1, then again 5 and just zero sales What can be the reason for the same
Variance in sales is nothing new, it's not something you can control. Some days you do well others you do not. The key is monitor over a long period of time and then come up with an average number of sales per day. You can decide whether you're paying too much for advertising or not. Sometimes it can also be down to what day it is. For instance some products do better in the weekends because people have more time to make a buying decision.
