How does the KWFinder fetch keyword ideas from Google?

Keyword ideas are fetched straight from the Google Auto Suggest API + some other Google sources (secret 😉). 

More than 250 modifiers are used around your seed keyword to try and extract as many keyword ideas as possible, with a focus on high-intent keywords.

A few examples of the modifiers used : "how to", "best", "top", "review", "vs", "why", "when", "what", "idea", "for" "alternative", "beginner", ... and also some more advanced ones : "how to ... when", "wow to ... if", ...

All keyword ideas found are queries that users type in Google (ie there are real people searching for them).
