Site is not indexing well after a long time

Hello,

Thank you for contacting us and we regret the inconvenience caused.

I searched the website on Google but was unable to replicate the issue. The website is already indexed. Please follow this link for a quick reference:
https://www.google.com/search?q=site%3Athelabelshow.nl&rlz=1C1CHZN_enIN948IN948&oq=site%3Athelabelshow.nl&aqs=chrome..69i57j69i58.8672j0j4&sourceid=chrome&ie=UTF-8

I also checked a few pages on the website and they’re already set to index.

The website was last crawled on 29 Jan 2022. Here’s a screenshot: https://i.rankmath.com/LvgRgJ

However, I tested the variations of sitemaps using https://httpstatus.io/, I found that all the variations are returning a 200 status.

Except for the preferred variation (which should return only a 200 status), all the non-preferred variations of the website should redirect to the preferred variation and return a 301 + 200 status.

Please follow the steps in this link:
https://rankmath.com/kb/couldnt-fetch-error-google-search-console/#5-check-for-the-correct-version-of-the-sitemap and redirect to the correct variation.

You can also get in touch with your web host as they would be able to assist you with this.

Once done, please clear your website’s cache. Then, remove all the sitemaps from your Google Search Console account, and submit only the main sitemap: /sitemap_index.xml.

Further, give Google some time to crawl your website again and see if more pages get indexed.

P.S. I logged into your website’s admin area and excluded the sitemaps from being cached by “WP Optimize” plugin.

Hope this helps.

Thank you.
