90 is the floor. Below 50 is the problem.
Google PageSpeed Insights scores on a 0-100 scale. 90-100 is Good. 50-89 Needs Improvement. 0-49 is Poor. Aim for 90 minimum on both desktop and mobile. Mobile score matters more. Google uses it for ranking. WordPress sites with themes and plugins typically score 40-65. Custom Next.js sites consistently hit 90-98. Every CrftdWeb project is built to reach 90 as a minimum. Not a target. A requirement.
