What is your preferred method or app/tool for conducting a competitive analysis?

I use all the open internet no tools in particular. Interested in this thread

Rather than comparing features, or even brands or marketing, the essence of competitive analysis is to know and love their business strategy.

Honestly just doing a google search

I use my own tool to check keyword competition in SERPs: https://multilinkbuilding.com/ke...

What do you mean by competitive analysis, is it like Google Lighthouse?
