I used to use Market Samurai and it was my favourite keyword research tool, until they stopped getting data from google and shifted to bing instead.
Google Keywords Tool is inaccurate most of the time, and is very limited. Also other keyword research tools are limited and don't have many of the nice features Market Samurai has.
My question is: is there any other excellent and reliable keyword research tool, similar to Market Samurai, that still gathers its data from Google's search data centers?
What is the best keyword research tool you'd recommend, (that still works post the new Google changes/updates) for SEO research and PPC research?
