Slow response (over 2s)

Why it matters

Slow server responses hurt Core Web Vitals and reduce crawl rate.

How to fix it

Improve server performance: caching, database queries, CDN, or hosting resources.

How Crawlune finds it

Crawlune flags Slow response (over 2s) automatically on every crawl and lists the affected URLs under theResponse codes tab, where you can filter, inspect each page and export the list to CSV. The free version crawls up to 500 URLs with every check enabled.
