Experience with Audience Exclusion
With everything that has been said over the last while about how user experience is effecting SEO right now, and how important it is as google ranking factor.
Re: Experience with Audience Exclusion
Because of the very reasons you stated - how can an algorithm and crawler analyse this objectively?
there are objective signals like is it mobile friendly, is the site fast, etc. they count a bit for SEO.
worry about SEO for SEO and worry about UX for UX.
for UX you need to be thinking about heat mapping and session recording try a tool like VWO or hotjar
NB: this is prob not really the right forum for this type of Q as it is not an SEO forum you can head over to a google webmaster forum but a lot of the best seo advice and community forum you'll find on moz.com
