Connect with your customers from the first click
Table of Contents
WhatsApp is not just a messaging app: it’s where your customers talk to friends, family, and increasingly, to brands. That’s why businesses are investing in campaigns that turn advertising into direct, accessible, and effective conversations.
This guide is designed to help you optimize your WhatsApp advertising campaigns to the fullest, whether you use Meta Ads or Google Ads to drive customers into a direct conversation. You’ll learn how to test what works, measure with real KPIs, and scale your efforts intelligently. All with clear examples and practical tips, regardless of your industry.
1. Advanced targeting: Reach the right people
A campaign on WhatsApp only works if it reaches the right audience. A great ad that doesn’t reach the right person simply doesn’t convert.
Both Meta and Google offer powerful targeting tools to attract truly interested users. Below, we’ll show you how to apply them on each platform.
Targeting on Meta Ads:
- Demographics: age, gender, location, language.
- Interests and behaviors: users who are into specific topics or have purchase histories.
- Custom Audiences: people who’ve interacted with your website, videos, emails, etc.
- Lookalike Audiences: based on the profiles of your best customers.
Practical tip: If you already have an organized contact base (in your CRM or on WOZTELL), you can create highly accurate audiences and launch very effective re-targeting campaigns. This allows you to personalize your ads, increase message relevance, and significantly improve your conversion rate.

Targeting in Google Ads:
- Demographics: Filter by age, location, language, or gender.
- Interests and behaviors: Show your ads to users actively searching for products or services like yours.
- Retargeting audiences: Reach people who already visited your site, used your app, or interacted with your YouTube channel.
- Similar audiences: Expand your reach based on profiles similar to your current customers.
Practical tip: Organize your database using a CRM like WOZTELL and use it to run personalized retargeting campaigns. This way, you’ll get more clicks, more conversations, and better results.
2. Copywriting, visuals and A/B testing: Grab attention and convert
In a crowded feed, you only have a few seconds to stand out. The text and visual of your WhatsApp ad define its success. It’s not just about creativity—it’s about clearly and empathetically communicating your value.
Practical tips for writing your copy:
- Use your customer’s language: talk like them, understand their concerns, and avoid unnecessary jargon.
- Focus on the benefits for the user, not just the features of the product or service. Example: instead of saying “bike with 18 gears,” say “a lightweight bike that lets you climb hills effortlessly.”
- Include a clear and direct call to action: “Send us a WhatsApp and we’ll help you choose the best model.”
Effective visuals:
- Use clear, well-lit, high-resolution images.
- Avoid overloading with text: Meta recommends that text not exceed 20% of the visual space.
- If using videos, grab attention in the first 2–3 seconds—especially for Reels.
- Make sure the visual element is adapted to the ad format (square, vertical, horizontal).
Meta offers a detailed guide on designing effective creatives for ads, including text use on images and recommended formats. Check it out here.
A/B testing:
Don’t guess. Validate with data. A/B testing lets you compare versions of an ad to see which performs best:
- Images vs. videos.
- Copy variations.
- Different audience segmentations.
- Alternative CTAs.
This helps you gradually improve performance based on real data—not intuition. Meta offers built-in tools to run these tests directly from Meta Ads Manager.
Practical tip: Even if your keyword density is ideal, ensure it feels natural in the text. Prioritize clarity and flow by using synonyms and related terms to avoid forced repetition and maintain an optimal reading experience.
3. Measure what matters: Key KPIs for WhatsApp ads
Main metrics:
- CTR (click through rate): percentage of people who clicked on your ad out of the total who saw it. A high CTR means the ad is relevant and attractive.
- Conversation start rate: of those who click, how many actually message on WhatsApp? This is more important than the click itself, as it measures genuine user interest.
- Response rate: measures how many conversations end with an effective reply from your team or bot. A high rate reflects good customer service.
- Cost per conversation: the cost you pay for each user who actually starts a conversation. This is one of the most relevant KPIs for lead generation or direct support campaigns.
- Leads generated / conversions: how many of those contacts become real opportunities or customers. This indicator connects marketing with business results.
Why go beyond CTR:
Although CTR is a good starting point, focusing only on it can be misleading. You might have a high CTR but a low conversation rate if your ad is attractive but unclear or misdirected.
In summary, defining your KPIs from the beginning according to your goal—be it support, lead generation, or sales—and having the means to measure each step of the process is key to campaign success.
4. How to measure results with UTM and CRM: Connect clicks to sales
UTM for WhatsApp
- Identify which ad or ad set generated each conversation.
- Analyze performance per campaign in Google Analytics or other platforms.
- Measure the real impact of each channel and optimize accordingly.
Connect your campaigns to a CRM
- Automatically record each contact that starts a conversation.
- Assign tags, funnel stages, or sales reps.
- Track the entire lead journey from the first message to the sale or close.
Key benefit: You won’t just know how many clicks your campaign generated—you’ll know how many real customers came from those WhatsApp conversations.
5. Integration with chatbots and automations: scale support without losing quality
Automate with smart chatbots
- Automatically reply to first messages to filter interest and provide an initial response.
- Ask for key user data like name, email, or specific need.
- Route the customer to the right department—sales, support, or post-sale.
- Offer 24/7 responses, even outside business hours.
Automations connected to the CRM
- Create or update contacts when someone writes on WhatsApp.
- Notify an agent when a conversation from a specific campaign arrives.
- Automatically tag leads based on their responses.
- Trigger follow-up emails, reminders, or remarketing campaigns.
Result: You scale customer service without compromising quality, and ensure full traceability of the lead journey.
