How it works
The Bing Keyword Tool harvests real autocomplete suggestions from Bing's public suggest API. That is the same engine that powers the dropdown in the bing.com search bar, so every suggestion is something real Bing users have searched for. We then enrich every keyword with monthly Google search volume, CPC, competition and a 12-month trend from the Keywords Everywhere API.
How the harvest works. The harvest runs in your browser, so the requests come from your IP address, not ours. It calls Bing's api.bing.com/qsonhs.aspx endpoint with your seed term combined with every letter and digit, plus about 70 modifier words. Those cover questions, comparisons, prepositions, buying phrases and tutorials. Bing returns up to 10 suggestions per prefix, and we keep every unique one. A typical 5-seed harvest produces 200 to 500 or more keywords.
Volume enrichment. As keywords arrive, we send them to the Keywords Everywhere API in batches of 100 for Google volume, CPC, competition and the 12-month trend. Bing does not publish per-keyword volume, so we use Google's data as a stand-in. In practice it tracks Bing demand well.
Country targeting. The Country dropdown sets both Bing's market hint (gl=us maps to mkt=en-US, and so on) and the country for the volume lookup. Volume and CPC are specific to that country's Google data. Your last-picked country is remembered for next time.
Careful pacing. The harvest sends about one request every 1.5 seconds to stay under Bing's per-IP rate limit. A full 5-seed harvest takes about 15 minutes. You can stop 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 one prefix of your seed term. Click the link icon to open the keyword in SERP Checker for a live look at the results page.
- Volume
- Google's average monthly searches over the past 12 months, from Google Keyword Planner via the Keywords Everywhere API. Bing does not publish per-keyword volume, so Google's number stands in for it. In practice the two track each other well.
- CPC
- The average cost per click advertisers pay in Google Ads for that keyword, in the country's currency. Microsoft Ads has often cost 30 to 50 percent less per click for the same terms. Treat this number as an upper bound when planning Bing ads.
- Competition
- Google Ads' competition score: Low, Medium or High. It shows how many advertisers bid on the keyword. It is a rough guide to SEO difficulty too. Organic competition on Bing is usually lower than on Google for the same term.
- 12-Month Trend
- A small chart of monthly Google search volume over the past year. Use it to spot seasonal patterns or rising and falling interest. Hover over any point for that month's exact value.
Frequently asked questions
What is the Bing Keyword Tool?
A free keyword research tool with no signup. It runs in your browser and asks Bing's public autosuggest for real suggestions around your seed term. Every keyword it finds is then enriched with monthly Google search volume, cost per click (CPC), competition and a 12-month trend from the Keywords Everywhere API.
Why should I care about Bing for SEO?
Bing's own market share is small, about 3 to 5 percent worldwide, but its reach is bigger than that. Bing is the default search engine in Microsoft Edge, which ships on every Windows machine. Bing also powers Yahoo Search results. And Microsoft Copilot and the web search inside ChatGPT both pull results from Bing. So ranking on Bing now means ranking in popular AI assistants too. Bing visitors also tend to be older and better off, so they often convert at a higher rate.
How does Bing's autosuggest work?
Bing exposes its autosuggest data through the public api.bing.com/qsonhs.aspx endpoint, the same engine behind the dropdown in the bing.com search bar. Each prefix returns suggestions that real Bing users have searched for. We combine your seed term with every letter and digit, plus about 70 modifier words. Those cover questions, comparisons, prepositions, buying phrases and tutorials. We keep every unique suggestion. A typical 5-seed harvest produces 200 to 500 or more keywords.
How is Bing different from Google for keyword research?
Two practical differences. First, competition for rankings on Bing is lower, so terms that are crowded on Google often have room on Bing. Second, Bing users skew older and use desktops more. Their queries are longer and more formal, with more direct questions. For the same seed you will often see more "how to" and "what is" suggestions on Bing than on Google. Run this tool and the Google Keyword Tool on the same seed to compare.
Do these keywords help with Microsoft Ads?
Yes. Bing's suggestions come from real searches on Bing, so they are a good source of targeting ideas for Microsoft Ads. The CPCs we show come from Google Ads, not Bing, but they are a fair guide. A keyword that is expensive on Google is usually expensive on Bing too, in proportion. Microsoft Ads has often cost 30 to 50 percent less per click than Google for the same terms. That 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 phrase, from Google Keyword Planner via the Keywords Everywhere API. Bing does not publish per-keyword volume. In practice Google volume tracks Bing demand well. A term that is popular on Google is usually popular on Bing too, at a smaller scale. Read the number as a relative popularity signal, not a Bing query count.
Why does the harvest take about 15 minutes?
To stay under Bing's per-IP rate limit, we send about one request every 1.5 seconds. A 5-seed harvest makes about 530 calls (5 seeds times 106 prefixes), so it takes about 15 minutes. Any faster and Bing would throttle or block your IP. Leave the tab open. Results stream into the table as they arrive, and you can stop early and keep what has been found so far.
How accurate is the data?
The suggestions come live from Bing, so they reflect real recent searches. Volume and CPC come from Google's Keyword Planner via the Keywords Everywhere API, the same source most professional SEO tools use. Numbers are Google's average monthly searches over the past 12 months. For keywords with 1,000 or more searches a month the data is very reliable. For long-tail terms under 100 a month, Google rounds into coarse buckets. The competition score shows Google Ads bidding, which is a rough guide to SEO difficulty.
