I just have the free version right now so I don't know all that the pro one can do. But even the free version has A LOT of tools you can use, I haven't even figured them all out yet. But one that I have used is their Content Optimizer. You can take a new or existing content piece of yours, and compare it to one of your competitor's pieces on a similar topic, and see where you might be lacking based on the keywords that are used in each piece.
If only it were that easy – right? I’ll be the first to admit – it’s not always that easy. I’ve created lots and lots of these types of sites over the past few years – and only a handful of them worked out. It can be a very hit or miss thing. But I do have one site in particular that I would like to highlight for you. It happens to be the very first niche website that I ever created! Why highlight this specific site? Because my very first attempt at a niche site happens to still earn more than enough money each month to pay for the expenses associated with Long Tail Pro! Check out the screenshot below from my Adsense account which shows stats for just this one site for exactly one year previous from the day that I am writing this post.
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.
