<b>Log the right fields: Nginx/Apache format tweaks for SEO</b>
Default log formats omit data you'll wish you had. These sources fix that.

→ <b>Nginx log_format docs</b> — add <code>$request_time</code> and <code>$upstream_response_time</code> so you can see which URLs make Googlebot wait.
→ <b>Apache mod_log_config manual</b> — <code>%D</code> (microseconds) and <code>%{Host}i</code> for multi-site servers. Without Host you can't split bot traffic per domain.
★ <b>Pick of the week — Barry Adams on "log everything Googlebot sees"</b> — argues for capturing full UA, response time, and bytes, because that's how you prove slow pages throttle crawl rate.
→ <b>Cloudflare Logpush field reference</b> — if a CDN fronts you, your origin logs lie; pull edge logs instead.

Takeaway: add response time and Host now. You can't analyse fields you never logged.
