Best way to add reCaptcha / spam protection?

Hi – I’m using the Google Captcha Pro (reCAPTCHA) by BestWebSoft plugin which adds spam protection to all WP forms plus some popular plugins like Contact Form 7.

Bestwebsoft provides guidance for adding reCaptcha to custom forms here:

Honestly, this is above my paygrade ??

I’m looking for the best way to add spam protection to FAQs – any help would be greatly appreciated.

Thanks!
