You can also periodically ad color to your ad instead of jumping to a bigger ad size. Remember the bigger the ad the bigger the impression you will make on your target audience.
A new business should consider placing
as large of an ad as they can possibly afford, especially the first few months.
Remember, most small business people invest tremendous amounts in their
businesses before it is ready for the public to enter or for you to provide a
service to the public. When planning a
new business it is important to allocate enough financial resources to be able
to announce to your community you are open for business in a big way!
If you own a business that does not have
a storefront then you need to consider your ad as the public face of your business. Usually people will find it easier to stop
by a new shop, or even try a new restaurant before they will pick up the
appointment and make the commitment of an appointment with you for a paid
service (this is especially true of personal-type services.) In these cases a photograph is extremely
important so that the potential buyer gets to know you and feels you are part
of the community.
A practical consideration regarding your advertising is that it needs to be large enough to accommodate all the information you want your audience to see. Usually an ad will include a mixture of graphics, logo, photographs and copy. Trying to cram too much information in the wrong ad size can make your advertising look amateurish and unprofessional. Also, depending on the type of business you own a small ad may convey the impression that your business cant afford quality advertising.
In the long run if you have to choose
between a bigger ad size and running a smaller ad more often go with the
smaller ad. Consistency over time is much more important than big size.
