Hazel Hollis launched her Halloween-themed campaign in October 2025 and achieved 227 conversions and 2.34x ROAS. It wasn’t the Halloween magic that made the difference. It was her decision to follow a data-backed strategy built by our ad manager and stay consistent, instead of guessing at targeting with no way to measure it.

From her campaign blueprint to her final numbers, see how a mid-level ad budget delivered fangtastic results in this eCommerce case study.

The Goal

Hazel Hollis owns a small US-based clothing brand with both an online store and a physical location. She designed the Pumpkin Duo Signature Series, a Halloween-themed collection for couples and working professionals. To make the season spook-tacular for her brand, she decided to launch a pay-per-click campaign with a mid-level ad budget on 7SearchPPC. She reached out to our ad manager with her Halloween advertising specifications to get useful insights and avoid wasting her budget.

Hazel Hollis Advertising Specifications

Hazel was short on time for in-depth research, but she didn’t want to leave targeting, timing, or creatives to guesswork. She asked our ad manager, Kevin, to build an advertising plan for her Halloween-themed clothing series. This approach made a significant difference in her PPC Halloween campaign’s outcome.

The PPC Ad Strategy

After receiving the brief, Kevin sent Hazel a detailed PPC advertising plan for the Halloween season. He recommended that Hazel should:

• Focus on the US market, as 71% of consumers planned to buy costumes and Halloween costume spending was projected to reach $4.3 billion in 2025, as per the National Retail Federation (NRF).
• Target major US states via mobile and desktop.
• Narrow the schedule to peak engagement hours, when the audience is more likely to act: weekdays during evenings. and weekends after 12 p.m. (US time).
• Create banner creatives in different styles and sizes to resonate with couples and corporate professionals on a personal level.
• Offer limited-time discounts, bundle offers, and free shipping, and highlight the core benefit in a clear, simple, ghoulishly good way.
• Use three different daily budget levels to test and save budget for the peak Halloween shopping window.
• Regularly monitor performance in Voluum to identify weak points in the pay-per-click advertising strategy.
• Apply the 80/20 Pareto Principle to identify the top-performing elements and focus on the inputs that deliver the most results.

The Implementation

As planned, Hazel launched one banner ad campaign with four different creatives: two specifically for couples and two for office professionals.

After two weeks, Kevin reviewed the campaign, since it had gathered enough data to evaluate. He found that traffic and conversions were coming in, which was a positive sign. To dig deeper, he applied the 80/20 rule to identify which elements drove the most results. These included:

• Offers that drove the most purchases
• Creatives and landing pages with the highest engagement
• Ad angles that resonated with each audience
• Hours of the day with the best conversion rates

After the analysis, Kevin gave Hazel a few suggestions, including highlighting the CTA in her creatives and at the top of her landing page, and prioritizing the ad angle and offers that brought the most conversions. He also told her to use 7SearchPPC’s Halloween offer while adding funds to receive the 20% bonus, worth $500, in her wallet.

The Result: What This eCommerce Case Study Revealed

Over the 30-day Halloween campaign, Hazel achieved 533,004 impressions and 11,148 clicks, with an overall spend of $7,274.63 and $725.37 in savings from the bonus she added afterward.
