Homepage tells search engines not to index it
Effort to fix: Quick win (under an hour)
Why it matters
A noindex directive removes the page from search results entirely. This is usually left over from a staging setup.
How to fix it
Remove noindex from the robots meta tag and the X-Robots-Tag header on public pages.
On WordPress
Untick Settings > Reading > 'Discourage search engines from indexing this site', and check your SEO plugin's per-page settings.
