Do International SEO and Go Beyond Borders

Do with semantics whatever floats your boat
After suggestions are collected, refine the semantics however you want. Filter, sort, tag keywords, group them automatically or manually or add new queries. Check rankings for the keywords to see how a website performs and track progress. Handle semantics online from different devices, or share access with your team and collaborate.
Pull Keywords in Just 3 Steps
Add Seed Keywords
Type in or paste seed phrases. The shorter the phrases, the more keywords will be collected.
Pick Search Engines and Locations
You can pick both Google and Bing and hundreds of locations at once.
All Done!
Do further keyword research analysis: check search volume, delete irrelevant phrases and cluster keywords.
Check Search Volume and Don’t Play Tiddlywinks
After the keywords are collected, separate the sheep from the goats — check search volume and see for which keywords people search most. But don’t put off low‑demand phrases: not very popular, they still can bring customers who know what they exactly want and are likely to bring more conversions.

Can I narrow down the search? I have the list of words I don't wanna see in my semantic core.
Yes, you can specify negative keywords while setting up the check, and phrases containing them won’t be added to the semantic core, so that you can save your time refining the keywords afterwards.
How accurate is Thundo search volume?
We pull data directly from Google Keyword Planner both local and global, so these are reliable numbers of what Google thinks of the keywords popularity.
Can I delete duplicates or irrelevant phrases? And if there’s plenty of them?
Don’t bother about the duplicates — we cut them out automatically, so they are never added to your semantic core. Then you can do with keywords whatever you want: filter and sort them, delete, group manually and so on, even if you’re working with hundreds of thousands of phrases.
