/tech/ - Technical SEO

been looking at some crawl logs from a massive ecom client lately. everything looks fine until you hit the deep paginated stuff. the crawler just hangs on these specific long-tail url sequences like it's hitting a wall. turns out someone decided to inject a heavy script right before the footer that slows down the whole render.
>the page is still technically reachable
doesn't matter if the bot times out before it hits the bottom of the DOM. we're seeing massive latency spikes on these deep links. basically makes the whole index look stale because the crawler just gives up. it's always a third party tracking script
