Add a Favicon Asset: Small Icon, Big Impact

One of the easiest and most overlooked tactics for improving your Yahoo! JAPAN search ad CTR is setting a favicon asset — a small website icon that appears next to your ad in search results.

When advertisers don’t set a favicon, a default “globe” icon is displayed. This generic image blends in with other results and doesn’t create any brand recognition. However, when you upload your brand’s actual favicon, it adds instant familiarity and trustworthiness.

The numbers speak for themselves

After implementing favicons for smartphone search ads, advertisers saw an 8.5% increase in CTR compared to the default globe icon.

Why It Works

  • Visual Branding: The favicon is a mini logo, boosting recognition and recall.
  • Trust Factor: A custom icon subtly signals professionalism and credibility.
  • Mobile Visibility: On mobile screens, where visual space is limited, even a small icon stands out.

📌 Pro tip: Make sure your favicon is clean, high contrast, and recognisable even at small sizes. Simpler designs often perform better.

Use Image Assets in Search Ads: Boost Engagement Visually

While traditional search ads are text-based, Yahoo! JAPAN allows the use of image assets in search ads, and this can be a game-changer.

These images appear in a well-optimised format and are selectively shown, typically appearing in one out of every three search results. This frequency gives your ads a good chance of standing out without overwhelming the user experience.

When you include images:

  • Ad groups with image assets show an 18% increase in CTR.
  • Overall CTR across all search ads improves by around 3%.

Why It Works

  • More Visual Real Estate: People are naturally drawn to images, especially in otherwise text-heavy environments.
  • Contextual Relevance: Images can quickly communicate product use cases, moods, or brand aesthetics.
  • Differentiation: In a sea of plain text, a striking image instantly grabs attention.

📌 Pro tip: Test a few different visuals to see what resonates with your audience. Lifestyle shots, product close-ups, or even branded illustrations can work well depending on your industry.

Leverage Ad Display Assets: Expand Your Message

Yahoo! JAPAN’s ad display tools help advertisers improve their search ads. They can add more content, like detailed descriptions, multiple links, promotions, and structured data.

When these options are fully used, the ad space grows a lot. This creates a larger and more informative presence on the search results page.

Benefits of Ad Display Assets

  • Additional Information: Add product specs, key benefits, or limited-time offers.
  • Multiple Click Points: Add links to specific pages like pricing, FAQ, or a landing page.
  • More Real Estate: Your ad visually dominates more of the page, pushing competitors lower.

Though harder to quantify than the favicon or image asset individually, expanding the ad area and adding deeper content contribute to higher engagement.

📌 Pro tip: Think strategically about what info users need to see before clicking — anticipate and answer their questions directly in the expanded ad format.

Final Thoughts

If you’re advertising in Japan, Yahoo! JAPAN is not optional — it’s essential. But simply launching ads isn’t enough. Like any platform, performance depends on how well you use the tools available.

To recap:

Each of these changes on its own will improve your performance, but when used together, they can deliver dramatic results, as our case study proves.

Don’t leave easy wins on the table. Take the time to optimise your Yahoo! JAPAN ads, and you’ll likely see your click-through rates and conversions rise accordingly.
