If I bought 500 clicks and I get 140 subscribers is that good?
28% is not really high, but depends of course on a lot of different factors. your landingpage, traffic quality... More important is if you are able to get sales. If your subscribers are opening clicking buying. Just think of that: You are able to make 2 or 3 sales from your 140 subscribers they are opening your emails clicking to your offers. Then you ahve a 500 order with 50% optin means 250 these subscribers are not buying and not opening your emails. what would you prefer? Its all a numbers game mate :) always know your numbers
her is my landing page after they optin for their free gift
