strang add to url ?help=0&_wpnonce=8954472d94

You might wish to look at setting up rel canonical

Which lets you specify which URL you want Google to index, you can use a plugin like Yoast SEO to do this.

will look into this thank you
i was think using
Disallow: /*wpnonce
in robots.txt

what think

I wouldn’t use robots.txt for this sort of thing, it’s really the job for rel canonical.
