Bing has been reported testing new visual treatments for sitelinks in desktop search ads, but the available evidence does not verify the widely described addition of “white arrows.” The clearest current report, published by Search Engine Watch on October 9, 2026, describes light-blue bubbles around desktop sitelinks. A separate report from May documented a narrower, bordered design with different hover styling.
What Bing is actually testing
The strongest recent observation comes from Search Engine Watch’s October 9, 2026 report by SEO news reporter Sachin Patel. It says Bing was testing light-blue bubbles for desktop sitelinks. The sitelinks had previously appeared on a white background, and the change followed a similar light-blue treatment for Bing’s “People also ask” questions.

That report does not establish that Bing added white arrows. The arrow description may refer to an unconfirmed interpretation of the visual change, a separate interface variation, or a description that has not been independently documented. It is therefore more accurate to describe the current development as a reported light-blue desktop sitelink test.

The October light-blue treatment
- Device context: desktop search results.
- Visual change: sitelinks were observed inside or alongside light-blue bubble-like treatments instead of the earlier white presentation.
- Relationship to other Bing UI: the change resembles a recent light-blue treatment reported for “People also ask” questions.
- Status: observed testing, not a confirmed permanent redesign.
The May bordered format
A separate PPC News Feed report dated May 31, 2026 described another Bing search-ad sitelink experiment. That version used a narrower layout, smaller type and a border. On hover, the link text changed from blue to bold black. This is a distinct observation from the October light-blue bubbles, not evidence that both treatments were rolled out together.

What sitelinks are in Microsoft Advertising
Microsoft Advertising defines sitelink extensions as additional links in an ad that take customers to specific pages on a website. An advertiser can use them to direct people to product categories, services, support pages or other important sections instead of sending every click to the main landing page.
Microsoft’s API documentation says the platform determines which links are most relevant for an ad and documents up to 10 sitelinks for an ad. That means adding several sitelink extensions does not guarantee that every link will appear in every auction. The displayed set can vary according to Microsoft’s selection and the search context.

Why the visual treatment matters
Sitelinks occupy valuable space beneath an ad’s primary message. A bubble, border or hover-state change can alter how clearly users distinguish individual destinations, how much of the ad is visible, and how easily a person can identify a relevant page before clicking. Those are plausible design goals, but the cited reports do not provide usability testing, accessibility measurements or click data.

There is no evidence in the cited reports that either design has reached all Bing users or all advertisers. Neither report gives a rollout percentage, test population, geography, experiment duration or end date. The observations should be treated as interface experiments that may appear for some searches and disappear for others.
Advertisers may therefore see different sitelink styling across accounts, devices, locations and times. A person who sees a light-blue treatment should not assume that the same appearance is permanent or that every customer will see it.
Do the designs improve clicks?
No measured performance impact has been published for these tests. The reports contain no click-through-rate lift, conversion-rate change, sample size or controlled comparison. A different color, border or hover style may affect attention, but visual novelty alone cannot establish better advertising results.
Advertisers evaluating sitelinks should continue judging performance with their own account data rather than attributing changes to the interface without a controlled comparison. Compare comparable periods, devices and campaigns, and account for changes in bids, targeting, creative and landing pages before drawing a conclusion.

- Keep destination pages specific. Use sitelinks for meaningful sections such as pricing, product categories, support or service details, with each URL matching its label.
- Review all available sitelink assets. Microsoft may select which links appear, so remove outdated destinations and check that every eligible page works on mobile and desktop.
- Record the interface you see. If your ads show bubbles, borders or hover changes, capture the date, device, market and campaign. This helps separate a temporary test from a broader account change.
- Measure outcomes independently. Track sitelink-level traffic and conversions where your reporting setup supports it, but do not claim a lift without a before-and-after comparison that controls for other campaign changes.
What remains unknown
- Whether the light-blue treatment will become the standard Bing sitelink design.
- Whether the reported white-arrow wording describes any separate experiment.
- How widely either variant is being shown, and in which countries or account types.
- Whether the designs change accessibility, click behavior or conversion rates.
- Why Microsoft selected these particular colors, borders or hover states.
The Bottom Line
Bing’s reported change is a light-blue desktop sitelink test, not a verified rollout of white arrows. A separate May experiment used narrower bordered links with smaller type and bold-black hover text. Microsoft has not confirmed broad availability or published evidence that either design improves clicks.
