Conclusion

To get started, it’s best to combine free and paid keyword research tools. For example, start with free tools like Google Keyword Planner for initial keyword ideas, then move on to paid tools like Keyword Finder, MOZ and Ubersuggest as they are lower cost. These can be better for those starting out on a budget. SEMrush or Ahrefs are great for deeper analysis but also require deeper pockets.

Also, if you’re new to keyword research, many of these tools offer free courses and tutorials that can guide you through the process. Google Skillshop and Ahrefs Academy (both free) are two great resources. Ahrefs also has a fantastic Youtube channel with lots of great videos about SEO and marketing.
