People are busy. No matter how impressed someone has been with your business, you may have to wait a while for them to provide a written recommendation. Ask as early as you can to be provided with one. Depending on the nature of your business it may be appropriate to get a video or audio recording as your testimonial instead. It is important to bear in mind that not many people are happy to talk to a camera or microphone and recordings can be difficult to play in some situations. Some of your site visitors are likely to be pretending to work or on public transport while browsing your site, and some people are conscious of using too much of their data allowance unnecessarily. Knowing your target market will help you enormously when deciding on the most appropriate format.
Don’t be afraid to ask for testimonials, or to be specific about the reason you want one. People are often quite happy to take the time to write something up for you if they know what you’re looking for. You can be specific about your intended purpose without scripting the testimonial yourself. As an example, we generally ask our clients to provide a testimonial about their experience with us to be placed on their portfolio page and in our community site.
