Search Volume · ZensInk

How it works

Autocomplete tells you what people search. Volume tells you how much. ZensInk uses the Bing Webmaster Tools API (free) to pull ~25 weeks of weekly impression data per keyword.

You get average weekly volume, latest week, trend direction (up/down/flat), and a demand level (HIGH / MEDIUM / LOW / MINIMAL).

Setup

Get a free Bing Webmaster API key:

Sign in at bing.com/webmasters
Go to Preferences → API Key
Copy your key

Create a .env file in the project root:

BING_API_KEY=your_key_here

Basic usage

Pass keywords directly (comma-separated OK):

python3 -m zens_ink.keyword_volume "ai tools,seo software,keyword research"

Or read from a file (one keyword per line):

python3 -m zens_ink.keyword_volume --file my_keywords.txt

Country and language

Defaults are cn / zh-CN. Switch for English markets:

python3 -m zens_ink.keyword_volume "seo tools" --country us --lang en-US

Export to CSV

python3 -m zens_ink.keyword_volume --file keywords.txt --csv results.csv

The CSV includes: keyword, avg_weekly, latest_weekly, quarterly total, trend, weeks, country, language.

JSON output

python3 -m zens_ink.keyword_volume "seo" --json

Bing vs Google volume. Bing numbers are lower in absolute terms (Bing has ~10% search market share), but the relative demand between keywords is highly correlated with Google. Use it for comparison, not for exact counts.

Tips

Batch queries. Each keyword takes 0.3s delay. 100 keywords ≈ 30 seconds.
Some keywords return no data. This is normal — Bing may not have enough impressions for very niche or new terms.
Trend needs ≥8 weeks. If a keyword has fewer than 8 weeks of data, the trend shows “insufficient”.
