HTML over 500 KB

Opportunity severity, in the Content tab

Why it matters

Very large HTML documents are slow to download and parse, hurting performance and crawl efficiency.

How to fix it

Trim inline scripts, styles and markup; paginate or lazy-load long lists.

How Crawlune finds it

Crawlune flags HTML over 500 KB automatically on every crawl and lists the affected URLs under the Content 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.
