I tested the free keyword research tools with my keywords boho tops. Some keywords tools is asking for free trial with credit card registration. Some offer free trial for a week. While I only get those are absolutely free with no string attach.
Here we go
Wordstream.com give huge stats with search vol for global, cpc value, competition, bing search volume and CPC value for bing with the competition. Complete right
wordtracker.com give good result too with competition and choices of search engine
ahrefs.com give me KD, search volume and update date.
Keywordsheeter.com give me result but no quantity
Questiondb.io is useless
Answerthepublic.com give me result but it is not user friendly
