Respect self referencing meta refresh

Configuration > Spider > Advanced > Respect Self Referencing Meta Refresh

You can disable the ‘Respect Self Referencing Meta Refresh’ configuration to stop self referencing meta refresh URLs being considered as ‘non-indexable’.

It’s fairly common for sites to have a self referencing meta refresh for various reasons, and generally this doesn’t impact indexing of the page. However, it should be investigated further, as it’s redirecting to itself, and this is why it’s flagged as ‘non-indexable’.
