Category: Reading Glasses Accessories

Brand overview 

Sticktite Lens offers a simple but innovative solution for everyday eyewear users. Their reusable, flexible stick-on bifocal lenses instantly convert regular glasses or sunglasses into bifocals. Built with patented adhesion technology, the lenses cling securely without glue, even underwater, and can be removed and reused across different eyewear. Sticktite Lens serves customers who want instant reading support without committing to permanent prescription changes.

Challenges 

Despite having a high utility and differentiated product, Sticktite Lens faced the common challenge of scaling profitably on Amazon. The category attracts mixed-intent traffic, including shoppers looking for vision products or unrelated accessories. This created wasted ad spend, unstable ACoS, and difficulty in consistently scaling campaigns month over month.

The brand turned to eStore Factory, a full-service Amazon agency, to develop a data-driven advertising strategy that drives sustainable growth without compromising efficiency. Our goal for the brand was clear: increase total sales while maintaining control over advertising efficiency.

Our approach

To drive sustainable growth, eStore Factory’s experienced Amazon advertising PPC specialists implemented a structured, performance-led advertising strategy focused on intent, scale, and efficiency.

1. Shifted toward high-impact ad formats

We redirected focus toward Sponsored Brands and Sponsored Display to capture high-intent shoppers earlier in the buying journey. We added high-intent search terms such as “stick on readers for sunglasses,” “bifocal inserts for sunglasses,” and “stick on reading lenses for sunglasses.”

These searches show shoppers who already own glasses and are looking to upgrade them, not buy new ones, which fits perfectly with Sticktite’s product and drives higher conversions. It allowed us to retarget product viewers and reach shoppers actively browsing eyewear and sunglasses.

2. Budget reallocation toward high-potential campaigns

Instead of increasing spending across the board, we identified campaigns that consistently deliver strong returns. Budgets were increased only where data showed clear scalability. Lower-performing campaigns were limited or refined, ensuring every dollar spent had a defined role in growth.

3. Profitable search term scaling

We isolated converting search terms and scaled them into controlled exact and phrase match campaigns. These search terms are “stick on bifocal lenses,” “bifocal stick on lenses," “stick on readers for glasses," and “stick on reader lenses.” It reflected clear, purchase-ready intent. Each phrase directly described the product and its core use. 

By scaling keywords that already demonstrated consistent conversion behavior, we leaned into existing demand rather than forcing discovery. This approach allowed us to grow volume confidently while maintaining tight control over relevance and efficiency.

4. Aggressive negative keyword control and ongoing optimization

To reduce wasted spend and protect efficiency, we applied aggressive negative keyword controls to filter out irrelevant traffic, including terms such as “pinhole glasses for vision improvement,” “stick on sunglasses film,” “eyeglass stickers for lenses,” “ bifocal stickers, and stick on magnifying lenses.”

At the same time, bids and budgets were reviewed and adjusted regularly based on real performance signals rather than fixed rules. This ongoing optimization helped maintain stable ACoS even as overall ad spend increased.

The result

The strategy delivered consistent, measurable growth across both annual and monthly performance.

Year-over-year growth

• 2024 total sales: $359,550.11

• 2025 total sales: $403,805.36

• Year-over-year increase: 12.31%

Monthly performance highlights

• 21% month-over-month growth in total sales, increasing from $26,771.44 in November to $32,336.88 in December through controlled campaign scaling.

• 31% increase in ad-attributed sales, driven by stronger Sponsored Brands and Sponsored Display performance and better search term targeting.

• Improved advertising efficiency, with ACoS dropping from 32.89% to 31.94% despite higher ad spend.

• 28% increase in ad investment deployed efficiently, ensuring incremental spend translated into incremental revenue rather than wasted traffic.

This case study shows that profitable scale comes from aligning budgets with intent, cutting waste aggressively, and scaling only what proves it can grow. For Sticktite Lens, this approach turned steady performance into controlled, year-over-year growth.
