Just a few suggestions;
(1) Make it easy for your potential customer.
(2) Make it easier for your potential customer.
(3) Make it even easier for your potential customer.
As an example; in your post above, you provide the web address to place an order. Is it “easy” for a potential customer to cut and paste this information? Is it “even easier” if you do the work and make it a “hot link”? Many folks won’t take the time to cut and paste. Already you may have lost a potential sale.
(4) Present as much information as possible as quickly as possible. You need to hold the interest of your customer, especially new potential customers.
Example; When I do cut and paste, the page that comes up shows me what? I see you are selling jigs. I see a photo of a pile of jigs with a description. Scrolling down the page, I see the SAME photo 3 more times. Only thing that changes is the size in the description.
My conclusion as a potential customer? Meh, don’t care for the colors shown, don’t know what hook size, not interested. Again, a potential sale lost.
It might be better, as a caption for the very first photo;
List the sizes
list the colors
TELL the folks “Click on the photo for more information”
(5) Offer more choices Only thing to choose as listed in the AD, is hook size.
Sure, down at the very bottom you say to contact you for other colors. Why? Why make it another step for the customer? Make it easy for the customer.
Set the ad up such that:
(A) select jig size.
(B) select UP TO 3 colors. Make the color selection a drop down menu. That gives them options within the package price. They select 1 color= you send 24 jigs of the same color. They select two colors= you send 12 of each color. They select 3 colors= you send 8 of each color.
Granted these are only suggestions, do with them what you wish.
