Commerce mostly is not, and mostly has not thought about it. Of 105 D2C and SaaS sites checked in September 2026, 86 never name an AI crawler in robots.txt at all, and only one blocks a retrieval crawler. Of the 12 publishers checked, all 12 block them. The decision is being made in publishing and skipped in commerce.

Removing client-side JavaScript took elivateseo.com to 100 on performance, accessibility, best practices and SEO, on mobile and desktop, with a Total Blocking Time of 0 ms. The zero JavaScript is what removed blocking time. Fonts, image dimensions and cache headers produced the rest, and none of those three involve JavaScript at all.
