@andreawang hey !
For example, you can embed this tool here for free on your website thanks to the « embed this calculator » button :
https://growthcalculators.com/cpm
And then create a page « free CPM calculator online » to rank for it.
I’m looking for other tools that are ready to be embed. 🙂
You can use free tools like Google Keyword Planner and Ubersuggest for keyword research, or opt for paid solutions such as SEMrush and Ahrefs that provide more comprehensive features including keyword tracking, competitive analysis, and backlink research, all of which can be crucial for effective SEO targeting.
