Usually, the various search engines provide their own keyword suggestion tools, which also include the number of searches for each of those keywords. The keyword researcher uses this information to select the correct keyword, depending on the SEO goals of the website. Around 20–25% of searches are very specific long tail keywords entered into Google every single day. It's easy to rank said keywords when there is the right amount of content and backlinks to match. Keyword research is a valuable and high return activity in the search marketing field.
Analyzing the current top 10 search results in Google is the most important part of keyword research. This is where you determine whether or not you can produce a webpage that can beat any or all of those results. The process is known as first page analysis – and it is by far the hardest process to understand and really figure out (especially when you first start out). Don’t worry though – Long Tail Pro has detailed and in-depth instructional videos available that show you exactly how to do this.
It would be great if you can provide comparative analysis of this tool with Google Keyword Planner. Since you’re using this tool so you can provide best comparison. One differentiation which I understood is that this tool works for yahoo and bing as well whereas Google keyword planner works only for Google but Google being a dominating search engine, gives the highest returns, so only this reason may not be enough to buy it.
