We have a free B2B Saas which averages around 60-70k daily impressions (on a weekday, much less on weekends) and we are looking for ways to cover costs and maybe actually make something at the end of it.
We are launching a premium version this year which will be charged and are looking at selling banner space in the free version - looking around the average rate seems to be around $3 to $5 per 1,000 impressions which would be around $180 - $300 per day which would be an OK start.
Obviously clients might be a bit miffed at adding banners so want to understand if it is still worth the effort to run with them?
