Tracking website on google at every searchable links

Hello.
Can you give me any information is it possible and if it's, how to check on what keywords my website is findable in Google?
Something like i have site about SEO. I can track main keywords like seo tools, seo tutorials etc, but sometimes our articles from blog are searchable from another keywords. How to get know under what keywords people can find my website? :/

If i will know it, i will be able to rank it higher, when i will see a potential to get top 10.

I need a FREE tool for this.
Thanks everyone for help!

Google Search Console is free...

you can track keywords, ranking, ctr, searches, geolocation and almost everything you need with google search console and google analytics.

You can use ahrefs, semrush, google, and a few other free tools, search for "free seo tools"

Once you have them, you can put them in a serptracker like serblabs.co.uk or serpbook.com

Google search console or SEMrush will do just fine. They're not extremely accurate, but they can do the job well.

yeah, google search console is good enough

Add a traffic tracking software like google search console. there's also statcounter as well, which is free, but has limited tracking file limit-but still does the job if you have a small site. If you are using cpanel, there are 2 free stat software included as well, and you may refer to the monthly summary for your sites through those stat software as well.
