1. Google Keyword Planner
The first free keyword research tool on our list is Google Keyword Planner (also known as Google Keyword Tool).
This free keyword planner provides accurate data and helps you go deep in your research process to find the most relevant keywords.
Keep in mind, though, to access the Google Keyword Planner, you need to have a Google Ads account.

Here are the data the tool provides for each suggestion:
- Avg. monthly searches.
- Top of page bid (low range).
- Top of page bid (high range).
However, unfortunately, as you can see in the example above, it no longer provides exact monthly search volume data for all keywords and only displays a range of data.
Plus, the competition level provided by Google Keyword Planner is NOT always 100% accurate.
Yet, despite these drawbacks, the tool still has many great features and potential.
Aside from the service being 100% free, it can generate keyword ideas like no other.
As with all other Google products, this service is also super user-friendly (and there is a minimal learning curve). In any case, the best way to master this tool is to check out some video tutorials on Youtube and read more blogs about it.
