Crawl invalid links

Configuration > Spider > Crawl > Crawl Invalid Links

By default the SEO Spider will not crawl or store syntactically invalid inlinks. Examples of syntactically invalid link types include –

<a href="https://example/">
<a href="hppts://example.com">
<a href="https:// example.com">

Enabling this setting means URLs that are syntactically invalid will be parsed, crawled and reported upon.

These will typically appear under ‘Response Codes > No Response’ as malformed links.
