The Multi-Channel Outreach Strategy
SACandE deployed a sophisticated seven-channel outreach strategy, each channel carefully selected to reach different segments of the target audience. Every promotional touchpoint used UTM-tagged URLs to enable precise tracking of traffic sources and conversion attribution.
TikTok
Short-form video content targeting younger industry professionals and raising awareness amongst emerging automotive specialists.
Google Business Profile
Local search visibility optimisation for regional industry searches and professional networking.
Facebook
Professional groups and targeted advertising to reach established industry networks.
Instagram
Visual storytelling and behind-the-scenes content showcasing conference value and speaker expertise.
WhatsApp
Direct messaging campaigns to professional contacts with personalised invitations and event details.
Email
Comprehensive email campaigns to curated lists of regulatory stakeholders and industry leaders.
Cold Calling: The Personal Touch
Traditional Outreach Meets Modern Analytics
The seventh channel—cold calling—demonstrated that traditional outreach methods remain powerful when combined with modern tracking capabilities. Sales representatives verbally shared the UTM-tagged URL during calls, enabling attribution even for this highly personal touchpoint.
This approach proved particularly effective for engaging manufacturers and securing block bookings, as decision-makers appreciated the direct, personalised contact.
Understanding UTM Tracking
UTM (Urchin Tracking Module) parameters are text snippets added to URLs that enable precise tracking of traffic sources in analytics platforms. They're invisible to website visitors but powerful for marketers seeking to understand campaign performance.
1
utm_source
Identifies the platform sending traffic (e.g., facebook, whatsapp, email)
2
utm_medium
Specifies the marketing medium (e.g., social, message, campaign)
3
utm_campaign
Names the specific campaign or promotion (e.g., Auto2025)
How UTM URLs Sync with CTA Buttons
The technical elegance of SACandE's tracking system lay in its ability to preserve UTM parameters throughout the entire user journey. When visitors clicked a UTM-tagged promotional link, those parameters were captured and maintained as they navigated through the site.
Initial Click
User clicks UTM-tagged promotional link from outreach channel
Landing Page
Parameters captured and stored in browser session
CTA Interaction
User clicks CTA button on landing page
Parameter Preservation
UTM string appended to destination URL automatically
Real-World Tracking Example
The Complete Journey
Consider a potential delegate who receives a WhatsApp message promoting the conference. They click the link, browse the landing page, and decide to register. Here's how the tracking works:
  1. User clicks WhatsApp link with UTM parameters
  1. Lands on main conference page
  1. Reviews content and clicks "Book Now" button
  1. Redirected to registration form with UTM intact
  1. Completes booking—conversion attributed to WhatsApp

Critical Insight: The original traffic source is retained throughout the entire conversion journey, enabling Google Analytics to accurately attribute bookings, quotes, and engagement to the correct outreach channel.
The Invisible Tracking Layer
What Users See vs. What Analytics Captures
A common misconception about UTM tracking is that the parameters are visible and disruptive to the user experience. In reality, UTM tags operate invisibly, working behind the scenes to collect data without affecting page layout, content, or user interaction.
Website visitors never see "utm_source=facebook" displayed on their screens. Instead, they experience a seamless, professional website whilst the tracking system quietly captures attribution data. This data flows into Google Analytics, where marketing teams can analyse performance under Acquisition reports, Source/Medium breakdowns, Landing Pages analytics, and configured Goals or Events.
This invisible architecture is precisely what makes UTM tracking so powerful for event promoters and conference organisers—you gain comprehensive insights without compromising the delegate experience.
UTM-Tagged URLs by Channel
SACandE created seven distinct UTM-tagged URLs, each carefully structured to identify its source channel whilst maintaining consistency in campaign naming. Below are the complete tracking URLs deployed across all promotional channels.
TikTok
utm_source=tiktok
utm_medium=social
Google Business Profile
utm_source=google
utm_medium=gbp
Facebook
utm_source=facebook
utm_medium=social
Instagram
utm_source=instagram
utm_medium=social
WhatsApp
utm_source=whatsapp
utm_medium=message
Email
utm_source=email
utm_medium=campaign
Cold Call
utm_source=coldcall
utm_medium=verbal
The Three Critical CTA Buttons
The landing page featured three strategically positioned call-to-action buttons, each designed to serve different delegate needs and decision-making stages. These CTAs were configured to preserve UTM parameters, ensuring complete tracking continuity.
1
Book Now
Direct path to individual delegate registration form. Destination: /book-now/
Primary conversion action for committed attendees ready to secure their conference place.
2
Get a Block Booking Quote
Form capturing delegate count, contact details, email, and phone. Destination: /quote-request/
Designed for organisations sending multiple attendees or manufacturers seeking group rates.
3
Learn More
Interactive flipbook brochure with detailed conference information. Destination: /brochure-viewer/
Content-rich resource for stakeholders requiring more information before committing.
Technical Implementation
Preserving UTM Parameters
When a visitor lands on the conference page via a UTM-tagged link, those parameters are captured by JavaScript or server-side logic. As the visitor navigates and clicks CTA buttons, the system automatically appends the original UTM string to subsequent URLs.
This technical implementation requires careful configuration but delivers invaluable attribution data. Marketing teams can trace each conversion back to its original source, even when the user journey involves multiple page visits and interactions.
Where Analytics Data Appears
Whilst UTM parameters remain invisible to website visitors, they generate comprehensive data visible in Google Analytics. Marketing teams access this information through several key reporting sections:
Acquisition Reports
Shows traffic volume and behaviour by campaign, revealing which channels drove the most visits and engagement.
Source/Medium Analysis
Breaks down performance by traffic source and medium, enabling direct comparison between platforms like Facebook vs. WhatsApp.
Landing Pages
Displays how visitors from different sources interact with specific pages, revealing content effectiveness by channel.
Events and Goals
Tracks conversions and configured objectives, attributing successful actions to their originating promotional channels.
Campaign Results Overview
The 2025 Auto Conference campaign generated substantial engagement across all three CTAs, with a total of 1,456 interactions tracked through the UTM system. The data revealed distinct patterns in how different channels drove specific actions.
651
Book Now Clicks
Direct registrations from committed delegates
468
Block Booking Quotes
Requests from organisations and manufacturers
477
Learn More Interactions
Information-seeking behaviours before commitment
Book Now Performance by Channel
Direct booking conversions showed clear winners, with traditional digital channels and messaging platforms outperforming newer social media avenues. The data suggests that delegates ready to commit preferred established, trusted communication methods.
Instagram, Facebook, and Google Business Profile emerged as the top performers for direct bookings, collectively accounting for 52% of all "Book Now" conversions. This suggests that delegates conducting active research through professional channels were most likely to convert immediately.
Block Booking Quote Requests
The block booking data revealed a fascinating pattern: cold calls dramatically outperformed all other channels for group quote requests. This 102-conversion result from cold calling represented 22% of all block booking quotes—nearly double the next-highest channel.
This outcome validates the power of direct, personalised conversation when selling to organisations and manufacturers. Decision-makers responsible for multiple delegate registrations responded best to human interaction, where complex questions about group rates, travel arrangements, and organisational logistics could be addressed immediately.

Block Booking Detailed Breakdown
The dramatic difference between cold calls (102) and the next-best channel, email (72), represents a 42% performance advantage. This data strongly suggests that for conference organisers seeking corporate block bookings, investment in professional sales calling infrastructure delivers superior returns.
Learn More Engagement Patterns
The "Learn More" CTA attracted delegates in the research and consideration phases—those not yet ready to commit but seeking comprehensive information. This button led to an interactive flipbook brochure containing detailed conference agendas, speaker biographies, regulatory content previews, and technical specifications.
Email and WhatsApp dominated this category, suggesting that recipients of direct communications were more likely to engage deeply with educational content before making booking decisions. This pattern indicates these channels attract thoughtful, methodical decision-makers who value thorough information gathering.
Learn More Channel Performance
Email led "Learn More" engagement with 84 clicks, followed closely by WhatsApp with 78. Combined, these direct communication channels accounted for 34% of all brochure views, demonstrating their effectiveness for reaching serious, information-driven prospects.

Strategic Insights: Email Excellence
Why Email Dominated
Email's first-place finish wasn't accidental. It delivered consistent performance across all three CTAs, suggesting it attracted the most diverse and engaged audience. Email recipients were equally likely to book immediately, request quotes, or conduct further research.
This balanced profile indicates email captured professionals at various decision-making stages—from curious explorers to ready-to-commit delegates. For conference organisers, this reinforces email's continued relevance despite predictions of its decline.
Strategic Insights: WhatsApp Power
Direct Messaging as Conversion Driver
WhatsApp's second-place finish with 246 total interactions demonstrates the power of personal, direct messaging in B2B conference promotion. Unlike broadcast channels like social media, WhatsApp enables one-to-one or small-group conversations that feel personal and immediate.
The platform performed particularly well for "Learn More" (78 clicks) and "Book Now" (103 clicks), suggesting WhatsApp recipients felt comfortable taking significant actions after personalised outreach. This highlights the value of relationship-driven marketing in professional conference contexts, where trust and credibility significantly influence booking decisions.
For event organisers targeting international audiences, WhatsApp's global penetration—particularly in Brazil, Germany, China, and South Africa—makes it an essential promotional channel.
Strategic Insights: Social Media Dynamics
Facebook and Instagram delivered strong, comparable performance (237 and 235 total interactions respectively), demonstrating their effectiveness for professional conference promotion when properly targeted.
Facebook Strategy
Excelled at driving immediate bookings (111 clicks). Professional groups and targeted advertising reached decision-makers ready to commit. Mature platform with established B2B networks.
Instagram Performance
Led all channels in Book Now conversions (116 clicks). Visual storytelling and speaker highlights built trust and credibility. Increasingly professional audience engaging with industry content.
Both platforms demonstrated that social media isn't just for consumer marketing—when content quality is high and targeting precise, social channels effectively reach professional, B2B audiences for conference promotion.
Strategic Insights: TikTok's Limitations
Awareness vs. Conversion
TikTok finished last with 165 total interactions, significantly trailing other channels. Whilst the platform excels at reaching younger audiences and generating awareness, it underperformed for conversion-driven conference promotion.
The results suggest TikTok works best as a top-of-funnel awareness tool rather than a direct conversion channel for professional conferences. Content may generate views and engagement, but translating that into registered delegates proves challenging.

Recommendation: Use TikTok for building brand awareness and showcasing conference culture, but don't expect strong direct bookings. Budget accordingly and pair with stronger conversion channels.
Strategic Insights: Cold Call Specialisation
The Block Booking Champion
Cold calling's results tell a nuanced story. Whilst it finished mid-pack overall (210 total interactions), it absolutely dominated block booking quotes with 102 requests—48% more than the second-best channel.
This specialisation reveals an important truth: different channels excel at different conversion types. Cold calling's personal, conversational nature makes it ideal for complex transactions requiring discussion—group rates, travel coordination, organisational logistics.
1
Block Booking Share
Cold calls captured nearly half of all quote requests
2
Book Now Share
Individual bookings less responsive to phone outreach
3
Learn More Share
Moderate engagement with informational content
Public Sector Engagement Patterns
Whilst not explicitly tracked in the UTM data, SACandE observed that public sector stakeholders—government regulatory bodies and policy advisors—showed particularly strong interest in the "Learn More" category. This behavioural pattern makes intuitive sense.
Why Government Engages Differently
  • Require comprehensive information for internal approvals
  • Need detailed agendas to justify attendance expenditure
  • Seek evidence of policy relevance before committing
  • Often involve multiple stakeholders in decision-making
  • Require documentation for procurement processes
This insight suggests conference organisers should create exceptionally detailed pre-event materials when targeting public sector delegates, as these resources directly influence booking decisions and internal approval processes.
Key Takeaways for Conference Organisers
1
Channel Specialisation Matters
Different channels excel at different conversion types. Email and WhatsApp drive balanced engagement. Cold calls dominate block bookings. Social media drives immediate individual bookings. Match channel to objective.
2
Direct Communication Wins
Email and WhatsApp's strong performance confirms that personalised, direct outreach outperforms broadcast marketing for professional conferences. Invest in these channels for highest ROI.
3
Don't Abandon Traditional Methods
Cold calling's block booking dominance proves traditional sales techniques remain powerful when applied strategically. Modern analytics simply make them measurable and optimisable.
4
Social Media Requires Strategy
Facebook and Instagram work for B2B when properly targeted. TikTok serves awareness goals but struggles with conversion. Allocate budgets accordingly based on campaign objectives.
5
UTM Tracking Enables Optimisation
Without UTM tracking, these insights would remain invisible. Structured attribution is essential for data-driven marketing decisions and proving ROI to stakeholders.
Conclusion: The Power of Measurable Marketing
SACandE's UTM tracking implementation for the 2025 Auto Conference demonstrates how modern analytics transforms conference promotion from educated guesswork into data-driven science. Every promotional effort was measured, every conversion attributed, and every marketing pound accounted for.
The campaign's 1,456 tracked interactions across seven channels and three CTAs generated actionable insights that will inform future promotional strategies. Email and WhatsApp emerged as primary investment priorities. Cold calling proved its continued value for corporate bookings. Social media showed promise when strategically deployed.
Most importantly, the structured approach enabled SACandE to justify marketing expenditure with concrete evidence, optimise channel mix in real-time, and identify high-performing platforms for scaling. This level of accountability and optimisation simply isn't possible without robust UTM tracking architecture.
"UTM tracking empowers campaign managers to attribute traffic accurately across channels, optimise messaging and CTA placement, identify high-performing platforms for future outreach, and justify scaling or curtailing efforts based on real data."
For conference organisers and event promoters seeking to maximise attendance whilst minimising wasted marketing spend, SACandE's case study provides a proven blueprint. The combination of multi-channel outreach, structured UTM tracking, and analytics-driven optimisation delivers measurable results and continuous improvement—turning every campaign into an opportunity to learn, refine, and excel.
