I think people's aresenal of keyword research tools are mostly the same: 1) You need a tool to examine search volume, most likely Google Keyword Planner 2) A tool to help you generate more keyword ideas. Tools that work with the search engines' autosuggestions are very popular such as KeywordTool.io and Ubersuggest 3) Then people might add a tool broaden the depth of their data, maybe including something like Google Trends or Moz's Keyword Difficulty tool.

I came across Longtail Pro this morning, downloaded the trial version and was about to buy the $97 program…seems like a good buy. But the more research I’ve done today, it seems the KC score is an absolute must for anyone who is serious about making money with niche sites. I hate to spend the bucks, but hate even more leaving money and possibly niche site success. Any advice?
Understanding which websites already rank for your keyword gives you valuable insight into the competition, and also how hard it will be to rank for the given term. Are there search advertisements running along the top and right-hand side of the organic results? Typically, many search ads means a high-value keyword, and multiple search ads above the organic results often means a highly lucrative and directly conversion-prone keyword.

Great article again. I was just thinking why can’t I find an article of yours on keyword research and then boom here it is. Thanks again. On another subject are your articles on link building still relevant ?. As I have been guilty of as Brian Deane calls it the publish and pray method. I would really like to know what is method of choice for link building. Thanks again Ian.
Long Tail Pro is a keyword research tool that helps you quickly find low competition keywords for your website.  In particular, the tool is built for people doing SEO (search engine optimization) as opposed to people doing paid ads (Google Adwords PPC).  I'm sure there are some advertisers that use the tool for paid ad keyword research, but the tool was built for SEO keyword research.
