You can certainly wrap the Ethnio script inside of another script that further limits the number of visitors who have the chance of seeing the screener. Are you ready for some math? You have 1 million uniques a day (congrats!). Let’s say you have the view frequency of your screener set to 1% inside Ethnio. If you wrapped that in a script that limited running the Ethnio code to 10% of your visitors, (see how this is becoming like a fourth-grade word problem), that would mean only 100,000 of your visitors would have a chance of seeing the screener, with only about 1,000 actually seeing it. Keep in mind that of this 1,000, only about 1-4% will actually respond.
