Good question.
Trial and error I think unless some of the long termers here have info on that.
I just go to the main page, but I now have two other domains pointing to the squeeze pages which I think are quite good.
Euro Millions for the euro millions lotto squeeze page
That one I have to change from normal Euro squeeze to Rollover squeeze as and when a Euro rollover comes about.
and
Play The Lottery Online. for the UK national Lottery squeeze page
You can check by going to your prospect page and sort into type of hits.
IE ' L' is for Leads......'T' is for Squeeze page etc
