As can be safely inferred from the question, I'm trying to get Google to index my site.

I'm using Wordpress 5.9 served by nginx (1.13.12), with SEOPress (5.6 up-to-date).

I let the wizard guide me for the settings and created a sitemap that I registered with Google Search Console - as advised.

I let Google do its work and came back later to check, and found that every page exposed in my sitemap returns a noindex meta (X-Robots-Tag with User-Agent 'Googlebot for smartphones').

I did uncheck the "discourage search engines..." checkbox in Wordpress Reading settings.

I also did reset opcache, and I don't have a wp cache plugin (I don't have that much traffic so far).

And when I load the pages in a browser or with curl the X-Robots-Tag is set to none...

$ curl -I https://www.alchimie-web.com
HTTP/1.1 200 OK
Server: nginx/1.13.12
Date: Tue, 26 Apr 2022 15:07:44 GMT

X-Robots-Tag: none

even with various User-Agents to try and reproduce what the Googlebot reads :

$ curl -A 'Googlebot/2.1 (+http://www.google.com/bot.html)' -I https://www.alchimie-web.com


curl -A 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' -I https://www.alchimie-web.com


curl -A 'Mozilla/5.0 (Linux; Android 6.0.1; Nexus 5X Build/MMB29P) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Mobile Safari/537.36 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' -I https://www.alchimie-web.com

The site never returns a X-Robots-Tag: noindex...

Any hint on what I'm doing wrong ?

Should I use another SEO plugin ? (though I read that the same problem sometimes occurs with Yoast...)

1 Answer 1


I have a nginx directive that set X-Robots-Tag to none for every page. I thought it was some kind of null value for the header...

Now that I took some time to RTFM, I learned that none means both noindex and nofollow... So it wouldn't let the SEO plugin do its job.

Now that I removed it, it certainly works better.
