What's your favorite keywork analysis tool?

I've been using market samurai for a while now and so far it's been great. I've noticed that it's gotten a bit slower lately though, so I was wondering what everyone is using now as their main keyword analysis tool.

I'm pretty OCD about cross referencing my keywords several times before I commit my time and effort to build and promote niche, so some more resources would be awesome.

I have a number of different tools, but find myself going to the Google Keyword tool quite often for initial research. I like Market Samurai, but as you said, its not the fastest tool around. To get a quick idea of search counts, I want the fastest tool available.

I use 4 tools

Seopressor
Scribe Seo
Google adwords keyword tool
Google

I try and focus on one keyword per post and include keyphrases and long tail keywords which have the same meaning

I like to write posts that strengthen my existing posts so i can link them all together with highly related content

I've written a few reviews about different seo tools for wordpress and the top 8 wordpress seo plugins

When you get really good at on page seo, you don't really need any tools except the free ones but the premium wordpress plugins help you learn and get to that stage.

I'm looking at using Wordtracker as an upgrade from Google Keyword tool.

I only use Google Adwords in my keyword analysis.
