Bingbot tester: check how Bing crawls your page
Bing, DuckDuckGo, Yahoo, and Ecosia all pull their search results from Bingbot's index. Combined they represent around 10-15% of global search - and significantly more for B2B audiences on Microsoft Edge. If your JavaScript site is invisible to Bingbot, you are invisible to all four.
This free Bingbot tester sends a real HTTP request using Bingbot's exact user-agent and returns the raw HTML Bing receives. Bingbot's JavaScript rendering is far less consistent than Googlebot's, so pages that look fine on Google may return an empty shell here.
Paste a URL below to see exactly what Bingbot crawls from your site.

- 3
Click 'Simulate crawl' to fetch your page with that bot's user agent
- 4
Review the HTML response - check for your page title, main content, and meta tags
- 5
Test multiple crawlers to compare how each one sees your site
How it works
When you select a crawler and enter a URL, we send a server-side HTTP request using that bot's exact User-Agent string. For example, selecting Googlebot sends the request with 'Mozilla/5.0 (compatible; Googlebot/2.1)' - the same identifier Google's real crawler uses.
Your web server receives this request and responds based on the User-Agent. If you have dynamic rendering, cloaking rules, or bot-specific logic configured, the response will reflect that. This is exactly what happens during a real crawl - we are replicating the full request/response cycle.
The returned HTML is then analysed for SEO elements: title tag, meta description, Open Graph tags, heading structure, canonical URL, structured data, and overall text content. Each element is scored, and the tool flags missing or problematic items with severity ratings.
When you select multiple crawlers, each one makes an independent request in parallel. The results are displayed side by side in a comparison table so you can spot differences - for example, a page that returns complete HTML for Googlebot but an empty shell for GPTBot.
Understanding Bingbot
Bingbot is Microsoft's web crawler powering Bing Search, DuckDuckGo, Yahoo Search, and Ecosia. While Bing has invested in JavaScript rendering capabilities, Bingbot's rendering is less consistent than Googlebot's and often fails on complex single-page applications.
Bing's market share is often underestimated. Combined with DuckDuckGo (which uses Bing's index), Yahoo, and Ecosia, Bing-powered search represents roughly 10-15% of global search traffic. For many B2B and enterprise sites, this share is even higher because Microsoft Edge defaults to Bing.
Bingbot crawls less frequently than Googlebot and has a smaller rendering budget. This means JavaScript-heavy pages are more likely to be indexed with incomplete or missing content on Bing compared to Google. If your site relies on client-side rendering, you may be invisible on Bing even if Google indexes you correctly.
Pre-rendering ensures consistent visibility across all Bing-powered search engines without relying on Bingbot's JavaScript rendering capabilities.
Frequently asked questions
Does Bingbot execute JavaScript?▾
Bingbot has some JavaScript rendering capability, but it is less reliable than Googlebot's. Complex SPAs, lazy-loaded content, and client-side routing often fail to render correctly for Bingbot.
Why should I care about Bing if Google is bigger?▾
Bing powers multiple search engines including DuckDuckGo, Yahoo, and Ecosia. Combined, these represent 10-15% of search traffic. For B2B sites, the share is often higher due to Microsoft Edge's default search engine.
Does DuckDuckGo use Bingbot?▾
DuckDuckGo uses its own crawler (DuckDuckBot) for some features, but relies primarily on Bing's index for search results. Ensuring your content is visible to Bingbot improves your DuckDuckGo visibility.
