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.
The highest number is the one that would give you the most potential return. If you have a big-time domain and can rank pretty easily on competitive keywords, start at the top. If you’re a newer, smaller site and can’t really play with the big guns yet, it might make more sense to start in the middle of the sorted keyword research list – these aren’t the “monster” keywords in your niche, but they’re also less competitive, and therefore easier to rank on.
To use this feature, click on the second tab that you will find on the top right bar. Type in the keywords that you want to view the performance of, and also type in the name of your domain. Hit the search button and allow the software to find whatever you are looking for. Site rank will analyze the top page of Yahoo, Google, and Bing to find where your site could be. Jaaxy will also show you how your post or page is performing, so you will know if it is climbing or dropping in the search.
