Does Bing SEO still matter in 2026?
More than it has in a decade. Microsoft Copilot draws its answers directly from Bing's index for 500M+ Windows, Office and Edge users. Sites not optimised for Bing are invisible to Copilot — which means invisible to a large slice of the enterprise buyer audience.
For most of the 2010s, Bing was a rounding error — Google commanded 92%+ of search share and SEO teams correctly deprioritised Bing. That calculus has reversed. Microsoft has integrated Copilot into Windows, Edge, Office, Outlook and Teams, which means Copilot is the default AI surface for hundreds of millions of enterprise users.
And Copilot runs on Bing. Not a separate custom index — the same Bing ranker and crawl you've been ignoring. Sites with stale or incomplete Bing presence can rank well on Google and still be invisible to Copilot, because the underlying index they're drawing from is different.
The fix starts with Bing Webmaster Tools: submit your sitemap, verify your domain, resolve any indexing errors. From there, the same on-page SEO fundamentals apply — just running against a different ranker. In 2026 this is genuinely the highest-ROI SEO work most B2B brands can do.
