Hello,
Thank you for getting in touch with us.
We have already replied to this query via email. Here is the reply again:
By default, Rank Math marks the tag archives as noindex and that is why they are not included in the sitemap either.
You are given an option to change that during the setup wizard but you might have missing that option.
You can make the tag archives indexable from WordPress Dashboard > Rank Math > Titles & Meta > Tags
Then, enable the tag sitemap from WordPress Dashboard > Rank Math > Sitemap Settings.
Do note that we do not recommend making tags indexable.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
we have already enabled it and activating the tags sitemap but without success
Finally, why do you think it is harmful having a tag sitemap?
Hello,
Tag archives do not add any value to your website and dilutes your page rank and authority.
If it isn’t working for you, please share a couple of tag archive URLs with us so we can check.
