A scanner that is set up using the correct keywords and filters, should approximately find 50 job posts per month.
To find the approximate number of jobs that the scanner will find in a month:
Go to the Auto Bidder tab of your scanner.
Scroll down to the Connects Expense section.
Here, you can view the data for the scanner for the past year. You can also see the monthly forecast for the scanner that GigRadar determines based on historical data.
By looking at the forecast in the above image, we can say that the scanner has detected an average of 150 jobs per month. Therefore, to submit around 300 - 600 bids per month, you may need a minimum of 6 scanners.
