  4. More than just a list of tools with backlinks, this blog is going to help you choose the right keyword research tools for you.

How To Choose The "Right" Keyword Research Tool?

Not all tools are the same. Nor do you need ALL of them at the same time. It's therefore essential that you hand-pick the tool(s) that are the 'best fit' for your requirements and style of research. Here's what you should look for in a keyword research tool:

  1. The Input - In most cases, the input is in the form of a seed keyword. Some tools will require more input - from website information to installing code on website - with increasing levels of complexity. It's essential for you to understand the level of input required to start using the tool; this is a part of the efforts you need to put in to get the result.
  2. The Result - This is what matters at the end of the day. What are the different parameters the tool will look at? What data will it provide? How will it help you in the keyword research? Answers to these questions will help you decide whether or not a tool works for you.
  3. The Source - The one thing that (probably) matters more than the result is the source of the data for the tool. Some tools like SEMRush use their own bots and maintain their own database. Others piggyback on big daddy Google, or other tools (via APIs) to get their source of data. When using tools, authenticity of data provided is absolutely vital. Make sure the source of data for the tool is reliable and updated. 
  4. The Time - Tools differ in their approach as well as the information they provide (in the context of keyword research). This reflects in the time taken to use a tool, which varies from one to another. Identify the tool(s) that you are most comfortable with, in terms of the time it takes to find the information for the keyword research. 
  5. The Cost - Tools come in all shapes, sizes and prices. While the most popular ones - like the Google Adwords Keyword Planner - are free (Wait! Is it the other way round 🤔?), there are quite a few keyword research tools (like SEMRush) which provide a mix of basic keyword data for free, and much more indepth data like competitor comparison for a premium fee. Choose wisely when going for a premium tool. The best way to do this is to take a free trial of the tool before you commit to spend money on it.
  6. The Effort - This is all the effort you will have to put in (time & cost) for the tool. This includes the time taken to put in the initial data, time and effort put in to setup the tool (if required), cost of subscribing to the tool (if it's premium), etc. Understand what the overall effort is going to be, before committing to one specific keyword tool.
  7. The Ratings - If you don't really have a lot of time, and need to choose a keyword analysis tool quickly, listen. Listen to the experts who have talked about the tools at length and reviewed them (there are a few reaaaally good ones out there). You can also look at the ratings that these tools have received from users. This gives you a clearer idea about the tool and whether or not it's going to help you.
