These days, I use the following when performing keyword research and brainstorming content ideas, especially for established sites:
Google Search Console
Ubersuggest - improved since Neil Patel acquired and opened it for public
Serpstat - have a paid account.
What's your stack for keyword research?

If you search keywords for topic ideas. The best to go for me is doing topical keyword research + Gap analysis with custom built spreadsheets
Tools I use:
Semrush (Having unlimited data access and pretty affordable ) >> using for exporting data
Google search
LSI graph
Keywordseverywhere (great chrome plugin)
Website autidor for TF-IDF analysis

Topical gap analysis with custom built spreadsheet (intersecting all the available data) for coming up with a data-driven content wireframe for content writers >>
All that basically led of having monthly organic traffic increase from 200 to 35K+ in recent 7 months on Chamaileon.io
Get me on Linkedin https://www.linkedin.com/in/kotee/
and will guide you through the process
What is more
Ahref has great tool content explorer >> you can set some filters based on your needs with 5< Ref domain and Organinc traffic x+ and that can help you find some great topics as well
KWfinder is great tool to quickly get an idea about difficulty of the topic to compete with
Have you tried ubersuggest? I find it pretty useful and using it along with Serpstat covers pretty much everything as far as keyword ideas is concerned.
Ahrefs – totally worth its $99/mo and usually one month is more than enough. They also have amazing guides in their blog.
The downside of it is that you have limited access on data and can't export for data analysis in excel
The plan that is good for getting access on the data starts from $399
Hm? I constantly download and merge CSVs on the $99/mo plan. You can export up to 100,000 rows per month.
Dunno I tested recently again 99$ plan and bumped to those limitations >> even on pricing page that indicate that
Second Ahrefs, worth the $99/mo for sure. cc @kashaziz
Sounds cool but a bit steep [$99/mo]
I use it for a lot more than just keyword research. For example, I'll analyze what pages on my competitors sites are doing the best in Google, what keywords they rank for and in what positions, where they're getting backlinks, etc.
Ahrefs
SEMrush
SERPBook
Ahrefs and KWFinder
Not to be a plug and plug an article, but I compared a bunch of tools keyword difficulties here: https://www.humanproofdesigns.com/keyword-difficulty-checker/
We published a bunch of articles on various sites and tested the KD scores on each tool to see how accurate they were. It could be done better with more sites and articles, but we worked with what we had.
I wish I included SEMrush though. I've heard good things about their KD score being aligned with the other tools.
For most in the IndieHackers level of revenue, it goes in this order:
Moz Keyword Explorer
SEMrush
Ahrefs
The right answer also depends on if you are going to use the same tool for AdWords spend, in which case I recommend SEMrush.
Ahrefs.com is solid
kwfinder
Try semrush.com. Nice tool to check your competitors and find out keywords they are using.
Bear in mind it is by Moz however still helpfull list at "Ranking the 6 Most Accurate Keyword Difficulty Tools" https://moz.com/blog/ranking-keyword-research-tools.
