-Must make them see you in 60 characters or less.Where do you advertise? Links, FFA's, Classified ads, opt-in email, news groups, message boards, search engines? All of them are limited in how many characters you can use. In ocean of ads, you have to grab viewers attention, then make them click.
Grabbing there attention does not mean SHOUTING! Viewers tend to see all CAPs as spam. Better to use spacing to grab initial attention. Example:
[Subject] Make Money Under One Plan!! this is HOT see what you think Internet Spy Kit!!! Kill Your Credit Card Debt! Bologna Sandwiches... Opportunity Triple your Income/ 1 Million Emails Retire Working at Home!!
Some use a trick with characters to try to get you to see them. I don't mind this is it is not used to extreme.
[Subject] Make Money Under One Plan!! this is HOT see what you think Internet Spy Kit!!! Kill Your Credit Card Debt! >>>Bologna Sandwiches<<< Opportunity Triple your Income/ 1 Million Emails Retire Working at Home!!
You'll notice I used another trick for attention getting. Getting to meat of matter, don't you want to find out why someone would have a link about bologna sandwiches? Be careful with this one though. If you use it in an email campaign, it better be humorous or about bologna sandwiches, or your email recipients may call it spam.
[Body] "...with 45 easy payments of $499.99, you'll still be able to afford bologna sandwiches."
That might be hard to stomach. Usually a question that needs to be answered is good for a headline. You have to read email or click link to get answer.
[Subject] "How do you get to Carnegie Hall?"
[Body] "Practice!"
In a banner advertising campaign, where I'm actually using a button, I have been getting a good response using very simple text. "Webtools" is text and button is sent to a specific audience of webmasters.
Out of masses of ads, you have made them see yours. It's not as simple as that, but out of trial and error and tracking I found out what works for me. You have to find what works for you, because there are various ways to get from point A to point B.
