Testimonials templates come in three kinds and people usually download the wrong one. There is the ask (the email and the form), the page (the layout and what goes around each quote), and the video (the question sheet). Only the first two are worth templating hard; the third is three questions and a link. This page is what belongs in each, and the part of every template you have to write yourself.
The ask template
Subject, first line about their specific result, the request in one sentence, the two-sentence size, the link, one line about where it will go. The only part you cannot template is the first line, and it is the part that gets the rest read.
The page template
Quote, name, title, company, photograph if you have one, and the specific thing it is evidence of. A wall of unattributed praise reads as invented; four attributed quotes on the page that sells the thing beat forty on a testimonials page nobody visits.
The video question sheet
Three questions with an example answer each. That is the whole template, and it is the same one you send whether the customer is recording on a phone or sitting in front of a crew. Everything else about the video: the framing, the length, the retake: belongs in one line of instruction, not in a document nobody opens.
Questions people ask about testimonials templates
Is it obvious when a testimonial came from a template?
The ask, no. The answer, yes: which is why the templates worth using prompt a specific story rather than supplying the words.
Where do I put the quotes?
On the pages that sell, next to the claim they support. Not all together on a page called Testimonials.
How many do I need on a page?
Two or three that are specific. More than four and nobody reads any of them.
