FAQ

Questions about
Keyword Tools

Quick answers to what users ask before trying these tools.

Where does the keyword data come from?
Tools pull from public sources - Google autocomplete, search engine result pages, and aggregated public ranking data. Volume estimates are directional, not exact.
How accurate are the ranking checks?
We query directly from a neutral location and parse the live SERP. Results match what most users in similar locations would see; personalised results may differ.
Do I need an account to use these?
No. Every keyword tool here runs without login. A few advanced bulk variants are paid, but the single-keyword versions are free.
Why are some checks rate-limited?
External search engines rate-limit anyone hitting them too fast. We share a fair-use quota so everyone gets results - heavy users should upgrade to Pro.
Can I export results?
Yes - most tools have a Copy / Download CSV button. The bulk variants email you a zipped report.
