What’s the Best Way to Do Google AdWords Competitor Analysis for Free?

Yo! For google adwords competitor analysis free, try the Google Ads Transparency Center. Just type in a competitor's URL and you can see their active ads.

Also, check out SEMrush’s free version—limited but gives some insights on competitors' keywords.

Ad Preview tool is decent but kinda basic. If you want deeper stuff, spyfu has a free plan too.

Hope that helps!
