User-agent: Google Page Speed Insights
Disallow: /
This instructs Google Page Speed Insights not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders.

Search your web server access logs for the string Google Page Speed Insights (case-insensitive grep: grep -i "Google Page Speed Insights" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants.

Allow: /
This allows Google Page Speed Insights everywhere except the listed paths. Path matching in robots.txt uses prefix matching - Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Why would I want to block Google Page Speed Insights?
There are two main reasons to block Google Page Speed Insights: 1. **Competitive intelligence**: Google users (your competitors) can analyse your backlink profile, keyword rankings, and site structure. Blocking prevents this. 2. **Crawl budget**: If your site is large, SEO tool crawlers consume crawl bandwidth without contributing to search rankings. Blocking frees up server resources for search engine bots. The trade-off: you also become invisible in Google's backlink database, meaning links pointing TO your site from other domains won't appear in competitor reports either.
