def __init__(self):
self.triggers = []
def add_trigger(self, event, delay_days=0):
"""Add a trigger for testimonial requests"""
self.triggers.append({

Displaying Testimonials Effectively
Layout Patterns
1. Grid Layout
export function TestimonialGrid({ testimonials }: { testimonials: Testimonial[] }) {
return (
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
{testimonials.map((testimonial) => (
<TestimonialCard key={testimonial.id} {...testimonial} />
))}
</div>
)
}
2. Carousel/Slider
// Testimonial carousel with auto-rotation
class TestimonialCarousel {
constructor(testimonials, interval = 5000) {
this.testimonials = testimonials
this.currentIndex = 0
this.interval = interval
this.autoRotate = true
}
start() {
this.timer = setInterval(() => {
if (this.autoRotate) {
this.next()
}
}, this.interval)
}
next() {
this.currentIndex = (this.currentIndex + 1) % this.testimonials.length
this.render()
}
previous() {
this.currentIndex =
(this.currentIndex - 1 + this.testimonials.length) % this.testimonials.length
this.render()
}
pauseAutoRotate() {
this.autoRotate = false
}
resumeAutoRotate() {
this.autoRotate = true
}
render() {
const testimonial = this.testimonials[this.currentIndex]
// Update DOM with current testimonial
}
}
3. Featured Testimonial
/* Highlight the most impactful testimonial */
.featured-testimonial {
background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
color: white;
padding: 4rem;
border-radius: 1rem;
font-size: 1.5rem;
text-align: center;
margin: 4rem 0;
}
.featured-testimonial::before {
content: '"';
font-size: 6rem;
opacity: 0.3;
position: absolute;
top: 1rem;
left: 2rem;
}

Measuring Testimonial Impact
Key Metrics
interface TestimonialMetrics {
// Engagement metrics
views: number
timeOnPage: number
scrollDepth: number
// Conversion metrics
conversionRate: number
attributedRevenue: number
// A/B test results
controlConversionRate: number
testConversionRate: number
improvement: number
}
// Calculate testimonial ROI
function calculateTestimonialROI(metrics: TestimonialMetrics): number {
const additionalConversions =
(metrics.testConversionRate - metrics.controlConversionRate) * metrics.views
const additionalRevenue = additionalConversions * metrics.attributedRevenue
return additionalRevenue
}
A/B Testing Framework
| Variant | Testimonial Display | Conversion Rate | Lift | |---------|-------------------|-----------------|------| | Control | No testimonials | 2.3% | - | | A | 3 text testimonials | 3.1% | +35% | | B | 1 video testimonial | 3.8% | +65% | | C | Mix of text + video | 4.2% | +83% | | D | Rotating carousel | 2.9% | +26% |
Winner: Variant C (Mix of text + video) with 83% improvement
Analytics Implementation
// Track testimonial interactions
function trackTestimonialView(testimonialId) {
gtag('event', 'testimonial_view', {
'testimonial_id': testimonialId,
'event_category': 'social_proof',
'event_label': 'testimonial_impression'
})
}
function trackTestimonialClick(testimonialId, type) {
gtag('event', 'testimonial_click', {
'testimonial_id': testimonialId,
'testimonial_type': type, // 'text', 'video', 'case_study'
'event_category': 'social_proof',
'event_label': 'testimonial_engagement'
})
}
function trackVideoTestimonialPlay(testimonialId, duration) {
gtag('event', 'video_testimonial_play', {
'testimonial_id': testimonialId,
'video_duration': duration,
'event_category': 'social_proof',
'event_label': 'video_engagement'
})
}
Advanced Testimonial Strategies
1. Dynamic Testimonial Matching
Show relevant testimonials based on visitor context:
interface VisitorContext {
industry?: string
companySize?: string
useCase?: string
referralSource?: string
}
function getRelevantTestimonials(
context: VisitorContext,
allTestimonials: Testimonial[]
): Testimonial[] {
// Score each testimonial based on relevance
const scored = allTestimonials.map(testimonial => ({
testimonial,
score: calculateRelevanceScore(testimonial, context)
}))
// Sort by score and return top 3
return scored
.sort((a, b) => b.score - a.score)
.slice(0, 3)
.map(item => item.testimonial)
}
function calculateRelevanceScore(
testimonial: Testimonial,
context: VisitorContext
): number {
let score = 0
// Industry match
if (testimonial.industry === context.industry) {
score += 10
}
// Company size match
if (testimonial.companySize === context.companySize) {
score += 8
}
// Use case match
if (testimonial.useCase === context.useCase) {
score += 12
}
// Recency bonus
const daysOld = (Date.now() - testimonial.createdAt.getTime()) / (1000 * 60 * 60 * 24)
score += Math.max(0, 5 - daysOld / 30) // Decay over 5 months
return score
}
2. Testimonial Widgets
Embeddable testimonial displays:
<!-- Embed code for customers to display testimonials -->
<script>
(function() {
const script = document.createElement('script')
script.src = 'https://yoursite.com/testimonial-widget.js'
script.setAttribute('data-testimonial-id', 'abc123')
script.setAttribute('data-theme', 'light')
document.body.appendChild(script)
})()
</script>
