what's the best keyword find tools?

for google adword ,,I need more keyword

Try kwfinder and keywordtool.io. Should be enough. Also please try doing manual research about competitors as the tools can be wrong.

BHW should allow creation of blog posts or forum pages where someone can post a list of such tools. Every 2-3 day someone asks for such tools. They should also post their own affiliate links to make some extra cash too. They will make a lot lol.

Are you looking for free or paid tools?

I would totally go for keywordtool.io and LSI graph (especially for secondary keywords). They are the ones I'm using the most at the moment. Hope these help!
