what's weird it's that lighthouse cannot check the robots.txt which is generated by rankmath. nerds.xyz/robots.txt i would try to create a bing webmaster tool for the site as a test (it's not indexed at the moment) and i would double check the server logs to understand what's really happening...

hey, the navigation is better (imho). You're still missing the links in your bio (you should also link back from your external profiles).
what's puzzling me is that you only have the home page linked. pagespeed.web.dev/analysis/htt... the performances are not great but that shouldn't be a problem.

My pleasure! Best of luck or as they say in Japan gambatte! 頑張って

Finally i would link in the top bar (and expand!) the editorial policy. Add your face and your credentials inside too. The snowflake wannabe chatbot that it's google, now need to be reassured that it's promoting real people, because of EEAT. Add your linkedin profile and other work profiles.

Also pagination is handled weird, the home page use a "query" parameter. nerds.xyz?query-ea03c5... internally the category pages are using the standard wordpress pagination. nerds.xyz/category/lin...
that might cause extra work for the google indexer in order to canonicalize the pages.

when i've tried a quick crawl with screaming frog, i was hit almost immediatly by a 429 error (too many requests).
Check your rate limiting settings, they might be a bit aggressive.
Also, you have 50 pages of articles, eg 500 articles written since june ? it might be a tad much for a new domain.

Chorus / Outro

Sleep, little traveler, safe and warm,

Wrapped in dark where wonders form.

(Dream on…)

Sing to the void with whispered grace,

Find your peace in distant space.

(Dream on…)

Verse 2

Soothe the wings of light that wander,

Near the gravity so deep.

Close your eyes as worlds grow fonder,

In this cosmic, silent sleep.

Chorus

Sleep, little traveler, safe and warm,

Wrapped in dark where wonders form.

Sing to the void with whispered grace,

Find your peace in distant space.
