By Editorial TeamGetting informed investors to buy into financial products, especially something as specific as Canadian stocks, takes more than a simple list of tickers. You need precision-targeted advertising that educates before it even tries to persuade. Here’s the teardown of a campaign we ran to pull retail investors into a curated list of Canadian growth stocks, using Automated Experimentation and Optimization (AEO) campaigns to dial in the messaging and audience. The main objective was to drive subscriptions for a premium research newsletter. Let’s see if it paid off.
Key Takeaways
- Our AEO testing on ad copy and visuals drove the Cost Per Lead (CPL) 22% lower than our initial benchmarks.
- We built a multi-stage retargeting strategy around what content people read, which produced a 3.5x higher conversion rate for newsletter sign-ups.
- Ad creative that directly compared sector performance trounced generic brand ads, giving us a 1.8% higher Click-Through Rate (CTR).
- Putting 30% of the budget into AEO testing in the first two weeks let us find the best audience segments fast, cutting down on wasted spend.
- We shifted budget to video testimonials from real subscribers in the last phase, which pushed our Return on Ad Spend (ROAS) up by 15%.
Campaign Overview: Engaging the Savvy Investor
A financial research client of ours, who focuses on North American equities, needed to boost subscriptions for their “Northern Growth Opportunities” newsletter in Q3 2025. This is a high-ticket service that delivers deep analysis and stock picks from the Canadian market. We were targeting self-directed retail investors, mostly in the 35-60 age range, who already showed interest in financial news. We knew from the start this group is skeptical and wants data, not hype.
The campaign ran for eight weeks (Sept 1 to Oct 27, 2025) on a $75,000 USD budget. We spent it all on Google Ads (Search and Display) and LinkedIn Ads. Success was measured by how many free trial leads we got, how many converted to paid subscriptions, our Cost Per Lead (CPL), and the final Return on Ad Spend (ROAS).
Strategic Approach: Education First, Conversion Second
Our strategy was built around an educational funnel. The hypothesis was simple: investors would be more willing to pay for a newsletter if they first saw the value in diversifying into specific Canadian sectors, like renewables or tech. So, our first ads were all about content, not direct sales pitches.
The campaign had three distinct phases:
- Awareness & Education (Weeks 1-3): We pushed traffic to blog posts and whitepapers that broke down Canadian market trends and sector-specific opportunities.
- Consideration & Nurturing (Weeks 4-6): We retargeted everyone who engaged with that first wave of content, this time offering them webinars and case studies that showed what the newsletter actually does.
- Conversion (Weeks 7-8): Finally, we hit the warm leads with direct calls to action for free trials and discounted subscriptions.
We walled off a serious chunk of the budget, about 25% ($18,750), just for AEO testing over the first four weeks. This let us iterate quickly on messaging and audiences which is absolutely necessary when you’re targeting a sophisticated audience like this. In my experience, skimping on early testing just means you end up lighting money on fire later by guessing what works.
Initial Performance Metrics (Pre-Optimization)
Before our AEO process really kicked in, the campaign’s baseline numbers looked like this:
- Average CPL: $12.50
- Overall ROAS: 0.8x (this was expected to be negative at the start)
- Average CTR (Awareness Ads): 0.9%
- Impressions (Initial 2 weeks): 1.2 million
- Conversions (Trial Sign-ups): 150
- Cost Per Conversion (Trial): $125
Creative Strategy: Data vs. Emotion
For the top of the funnel, we ran two completely different creative angles against each other:
- Data-Driven Insights: These had headlines like “Unlock Growth: Why Canadian Tech Outperforms” and used charts showing market performance.
- Opportunity-Focused: These were a bit softer, with headlines like “Your Next Investment Frontier: Discover Canadian Markets” and imagery of Canadian field or abstract financial graphs.
On LinkedIn, we ran carousel ads that let users swipe through different investment themes, “Renewables,” “AI,” “Mining Innovation”, with each card linking to a specific blog post. On Google Display, we leaned on responsive display ads, letting Google’s own AI mix and match our headlines, descriptions, and images to find winning combos.
A core part of our AEO strategy was rigorously testing these creative angles. We A/B tested everything: headlines, copy length, CTAs (“Learn More” vs. “Download Report”), and the visuals. For instance, we saw a real uplift just by swapping a generic stock photo of a business meeting for a specific chart comparing the TSX Composite Index against the S&P 500. A 2024 eMarketer report backs this up, saying that visually compelling data in financial ads boosts engagement, and we definitely saw that trend play out here.
Targeting Precision: Beyond Demographics
Our first targeting pass on LinkedIn was pretty standard, going after job titles like “Financial Advisor,” “Portfolio Manager,” and “Individual Investor,” layered with interests like “Stock Market” and “Equity Research.” On Google, we used in-market audiences for “Investment Services” and built custom intent audiences based on people searching for competitors or reading certain financial news sites.
The AEO process quickly showed us the limits of this broad approach. We found a goldmine in a segment we hadn’t prioritized: small business owners. Identified through LinkedIn’s company size filters and job titles like “Founder” or “CEO” at companies with 1-10 employees, this group engaged way more with content about long-term capital growth than short-term trading. That was a big surprise, as our initial personas didn’t really focus on them.
So we spun up separate ad sets just for them, tweaking the copy to talk about wealth preservation and generational growth, and adjusted our bids accordingly. This AEO-driven micro-segmentation did wonders for our CPL. It’s a classic mistake to treat all “investors” as one big group. The nuances are where you find your performance.
“According to HubSpot data, businesses that use HubSpot AEO generate 2.7x more marketing qualified leads (MQLs).”
What Worked: Iterative Refinement and Data-Driven Shifts
1. Dynamic Headline Testing on Google Search
We leaned heavily on Google’s responsive search ads, feeding the system 15 different headlines and 4 descriptions to play with. The algorithm then did the work, prioritizing combinations that drove higher CTR and conversions. We quickly saw that headlines mentioning “Canadian Stock Picks” or “TSX Growth Stocks” had a 30% better CTR than generic phrases like “Investment Opportunities.” Our all-star headline ended up being “Top 5 Canadian Growth Stocks for 2026: Free Report,” which pulled a 4.1% CTR.
2. Video Testimonials in Retargeting
Once we had people in the consideration phase, we hit them with short video testimonials (30-60 seconds) from existing subscribers. These weren’t slick corporate videos. They featured real people talking about specific benefits like “discovering undervalued gems.” On LinkedIn, these video ads hit a 45% average view-through rate (VTR), crushing our static image ads (28%). That human element worked, giving us a 2.5x higher conversion rate for trial sign-ups from users who watched at least 75% of a video.
3. Landing Page Optimization through A/B Testing
Our AEO work didn’t stop at the ad. We tested two different landing pages: one was a long-form sales letter, and the other was a concise, bullet-point summary. Despite some internal debate, the long-form page consistently won, converting 18% better for trial sign-ups. This just showed that for a product this complex, potential buyers want all the details and transparency they can get. We also added a simple summary table near the top of the page showing the newsletter’s past performance (e.g., “Average Annual Return: +18.5% over 3 years”), which boosted scroll depth and conversions.
What Didn’t Work: Overly Aggressive CTAs and Generic Imagery
1. Direct Subscription CTAs in Awareness Phase
Our early tests with “Subscribe Now” buttons on top-of-funnel Google Display ads were a disaster. The bounce rates were high and CTRs were abysmal (0.3%). People who are just starting their research journey are nowhere near ready for a hard sell. When we changed the CTA to “Download Free Report” or “Read Our Analysis,” engagement shot up and we cut our initial lead capture CPL by 15%.
2. Stock Photos of Generic Business Scenes
The ads with images of diverse people in a boardroom or someone holding a tablet just fell flat. They were too abstract and didn’t communicate any real value. Our AEO tests proved that images of actual market charts, relevant company logos, or even simple stylized growth curves got much more engagement. It seems obvious in hindsight, but the temptation to use cheap and easy stock photos is always there, and it almost always kills your impact.
Optimization Steps and Final Results
We held weekly AEO reviews to pore over the data from Google Analytics 4 and LinkedIn Campaign Manager. In these sessions, we’d kill underperforming ads and audiences and spin up new tests. For example, we saw people were dropping off after reading our “Renewable Energy Stocks” blog post. So, we created a specific retargeting ad just for them, offering a webinar on “Investing in Canada’s Green Energy Boom.” That single, targeted follow-up got a 15% conversion rate for webinar sign-ups from that segment alone.
Campaign Performance: Before vs. After AEO Optimization
| Metric | Initial (Weeks 1-2) | Final (Weeks 7-8) | Improvement |
|---|---|---|---|
| Average CPL | $12.50 | $9.75 | 22% Reduction |
| Overall ROAS | 0.8x | 1.6x | 100% Increase |
| Average CTR (All Ads) | 0.9% | 1.8% | 100% Increase |
| Total Impressions | 1.2 million | 2.8 million | 133% Increase |
| Total Conversions (Trial Sign-ups) | 150 | 850 | 467% Increase |
| Cost Per Conversion (Trial) | $125 | $58 | 53.6% Reduction |
We spent the full campaign budget and ended up with 850 trial sign-ups, which led to 170 full newsletter subscriptions. With the average annual subscription fee, the final ROAS of 1.6x is a solid return, particularly when you factor in the lifetime value of these subscribers. Our final cost per full subscription landed around $441, which is right in line with industry benchmarks for this kind of high-value financial product.
Conclusion
This campaign for Canadian stocks proved that a disciplined approach to AEO campaigns is essential for engaging sophisticated investors. By constantly testing and refining every element, creative, targeting, landing pages, we managed to slash acquisition costs and make the whole campaign far more effective. The big lesson for any marketer in the financial space is to front-load your budget with experimentation. Your smartest assumptions will rarely survive contact with real-world data.

What is an AEO campaign in marketing?
An AEO (Automated Experimentation and Optimization) campaign is a strategy where you use automated tools to continuously test different ad creatives, audiences, landing pages, and bid strategies. The goal is to let the system find the highest-performing combinations to maximize your results without you having to manually tweak everything 24/7.
How can I identify the best audience segments for financial products?
Go deeper than basic demographics. You need to focus on psychographics, behavioral data, and intent signals. Use tools like Google’s custom intent audiences or LinkedIn’s lookalike audiences. You should analyze engagement metrics (like CTR, time on page, video view duration) for all your segments and run A/B tests on ad copy that speaks to different investor pain points. And don’t forget to look at niche professional groups or communities.
What kind of ad creatives work best for promoting investment opportunities?
Data-driven visuals like charts and performance graphs, educational content like infographics, and authentic testimonials almost always perform well. Stay away from generic stock photos and vague promises. Your creative needs to clearly state the value proposition, whether that’s unique market insight or a specific diversification strategy.
How much budget should be allocated to AEO testing?
For a new campaign, especially in a competitive space, setting aside 20-30% of your initial budget for AEO testing in the first few weeks is a good rule of thumb. This lets you learn fast and optimize quickly. Once you’ve found what works and the campaign matures, you can scale back that percentage, but you should always have a small portion of your budget dedicated to ongoing testing and creative refreshes.
What are common mistakes to avoid when marketing Canadian stocks to investors?
Don’t make claims you can’t back up or guarantee returns. It destroys trust and can get you into regulatory trouble. Don’t use a ton of technical jargon without explaining it. A huge pitfall is failing to segment your audience, different investors have very different goals and risk tolerances. And finally, if your content doesn’t provide clear, actionable insights, people won’t engage.
