Before launching the actual solo advertising campaign in large ezines or in multiple ezines, you need to test your ad copy.
What You Should Test?
• Test the Subject Line - See which pull better, which sell more.
• Test the Lead - Send the same offer to the same list but change only the first couple of sentences.
• Test the Lenght of your Ad Copy - Which sells more, the long form or the short form?
• Test the Offer - If you're offering a 5% off, try offering 10% off and see what response you get. If you offer something for a limited time, try changing the amount of time your audience has to think about it.
• Test the Price - How will changing the price in your offer change the response?
• Test the Day and Time - Monday? Friday? First thing in the morning? Midmorning? Afternoon? Evening?
• Test Your Tone - Rigid, funny? Which draws more?
