Performance score under 50

Warning severity, in the performance tab

Why it matters

Lighthouse rates the page's loading performance as poor. Slow pages rank worse on mobile, convert less and burn crawl budget; a score under 50 usually means render-blocking resources, oversized images or heavy JavaScript.

How to fix it

Open the page in PageSpeed Insights for the audit list: defer non-critical scripts and CSS, compress and size images, cache static assets, and reduce server response time.

How Crawlune finds it

Crawlune flags Performance score under 50 automatically on every crawl and lists the affected URLs under the performance tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 550 URLs with every check enabled.
