How it works
The Bing Keyword Tool harvests real autocomplete suggestions from Bing's public suggest API (the same engine that powers the dropdown in bing.com's search bar) for any seed term you enter. Suggestions reflect what real users have searched for on Bing. We then enrich every harvested keyword with monthly Google search volume, CPC, competition, and a 12-month trend via the Keywords Everywhere API.
How the harvest works. The harvester runs in your browser via JSONP (calls go from your IP, not ours) and hits Bing's api.bing.com/qsonhs.aspx endpoint. We iterate your seed combined with the alphabet (a-z, 0-9) plus ~70 modifier words spanning questions, comparisons, prepositions, buyer-intent qualifiers, and tutorials. For each prefix Bing returns 0-10 suggestions; we collect every unique one. A typical 5-seed harvest produces 200-500+ keywords.
Volume enrichment. As keywords are harvested, batches of 100 are sent to the KE API for Google volume, CPC, competition, and 12-month trend. Bing doesn't publish per-keyword volume publicly, so we use Google's data as a relative-popularity proxy that correlates well with Bing demand in practice.
Country targeting. The Country dropdown selects both Bing's market hint (mapped from gl=us to mkt=en-US, etc.) and the volume-lookup country. Volume + CPC numbers will be specific to that country's Google data. Your last-picked country persists across sessions.
Conservative pacing. The harvest is paced at roughly one request every 1.5 seconds to stay below Bing's per-IP rate limit. A full 5-seed harvest takes ~15 minutes. You can stop early at any time and keep the keywords found so far.
Plan caps. On the Free plan you can run 500 keyword lookups per day across all our keyword tools combined.
What the columns mean
- Keyword
- The exact suggestion Bing's autosuggest returned for some prefix of your seed term. Click the cross-link icon to open the keyword in SERP Checker for a live SERP audit.
- Volume
- Monthly Google search volume averaged over the past 12 months, sourced from Google Keyword Planner via the Keywords Everywhere API. Bing doesn't publish per-keyword volume publicly; Google volume is used as a proxy that correlates with Bing demand in practice.
- CPC
- Average cost-per-click that advertisers pay in Google Ads for that keyword, in the country's currency. Bing Ads (Microsoft Ads) historically costs ~30-50% less per click than Google for the same terms, so think of this number as an upper bound for Microsoft Ads planning.
- Competition
- Google Ads' competition score (Low / Medium / High), reflecting how many advertisers bid on the keyword. A loose proxy for SEO difficulty: high ad competition usually correlates with high organic competition. Bing organic competition is typically lower than Google for the same term.
- 12-Month Trend
- Sparkline of monthly Google search volume over the past year. Useful for spotting seasonal patterns or rising/declining interest. Hover any point on the chart for the exact month-over-month value.
Frequently asked questions
What is the Bing Keyword Tool?
It's a free, no-signup keyword-research tool that harvests real autocomplete suggestions from Bing's public suggest API for any seed term you enter, then enriches every harvested keyword with monthly Google search volume, CPC, competition, and a 12-month trend. The harvester runs in your browser (calls go from your IP), and the volume data comes from the Keywords Everywhere API.
Why should I care about Bing for SEO?
Bing's direct market share is small (~3-5% globally), but its reach is bigger than that number suggests for three reasons. First, Bing is the default search engine in Microsoft Edge, which ships on every Windows machine. Second, Bing powers Yahoo Search results under the hood. Third (and increasingly important): Microsoft Copilot and the web-search component of ChatGPT both source results from Bing, so ranking on Bing now means ranking in popular AI assistants. Bing traffic is also typically higher-converting (older, more affluent demographic).
How does Bing's autosuggest work?
Bing exposes its autosuggest data via the public api.bing.com/qsonhs.aspx endpoint (the same engine that powers the dropdown in bing.com's search bar) using JSONP. Each prefix you type returns suggestions Bing has seen real users search for. We iterate your seed term combined with a-z, 0-9, and ~70 modifier words (questions, comparisons, prepositions, buyer-intent qualifiers, tutorials, etc.), collecting every unique suggestion. A typical 5-seed harvest produces 200-500+ keywords.
How is Bing different from Google for keyword research?
Two practical differences. First, Bing's competition for ranking content is genuinely lower, so terms that are saturated on Google often have headroom on Bing. Second, Bing's users skew slightly older and more desktop-heavy, so queries tilt toward less-mobile-typical patterns (longer, more formal phrasing, more direct questions). For the same seed you'll often see more "how to" and "what is" style suggestions on Bing than on Google. Run both this tool and the Google Keyword Tool to compare side-by-side.
Do these keywords help with Microsoft Ads?
Yes. Bing's suggest data is built from real searches happening on Bing, so it's a strong source of ad targeting ideas for Microsoft Ads campaigns. The CPCs we surface are from Google Ads (not Bing), but they're a usable proxy: a keyword that's expensive on Google is usually proportionally expensive on Bing. Bing Ads has historically been ~30-50% cheaper per click than Google for the same terms, which is part of the case for adding Bing to a paid-search mix.
Are the volume numbers Bing-specific?
No. The volume column shows Google search volume for the harvested phrase, sourced from Google Keyword Planner via the Keywords Everywhere API. Bing doesn't publish per-keyword volume publicly. In practice Google volumes correlate well with Bing demand: if a term is popular on Google, it's typically popular on Bing too (just at a smaller absolute scale). Read the number as a relative-popularity signal, not an absolute Bing query count.
Why does the harvest take ~15 minutes?
To stay below Bing's per-IP rate limit we space requests out at ~one every 1.5 seconds. A typical 5-seed harvest makes about 530 calls (5 seeds x 106 modifiers), which takes ~15 minutes. Hammering the endpoint faster than that gets your IP throttled or blocked quickly. You can leave the tab open and check back; results stream into the table as they're found, and you can stop early to keep what's been harvested so far.
How accurate is the data?
The suggestions are pulled live from Bing, so they reflect real recent searches. The volume and CPC data is monthly averages over the past 12 months from Google Keyword Planner, the same source most professional SEO tools use. For high-volume keywords (1k+/month) the data is reliable; for long-tail under 100/month, expect some noise. The competition score reflects Google Ads bidding intensity, which loosely tracks SEO difficulty for that keyword.
