How can override a meta tag?

Question

I have a website hosted in an absurd place. Earlier today, they added this to the "Head" section of my pages.

<meta name="robots" content="noindex, nofollow, noarchive">

Unfortunately, I cannot change the code directly, but I do have access to Robots.txt (which they also screwed, but I already fixed it), JavaScript and Html. Is there any way I can remove that one tag from my website? I tried this one solution, but it doesn't seem to be working:

document.querySelector('meta[name="robots"]').setAttribute("content", "all");

Any other ways I can do this, besides the obvious "it's about time you move to a different host lol"? Maybe there is, ultimately, something I can add to Robots.txt to override this?

Answer 1

Have you tried removing the meta tag from the dom and adding a new one?

Like this:

document.querySelector("[name='robots']").remove();

let metatag = document.createElement('meta');
metatag.setAttribute('name', 'robots');
metatag.content = 'all';
document.getElementsByTagName('head')[0].appendChild(metatag);

Answer 2

You can select the element using this code

document.querySelector("[name='geo.region']")

now once you have access to it, you can override it

Answer 3

if overriding doesn't work, use a hammer:)

remove the existing meta node

document.querySelector('meta[name="robots"]').remove();

create a new one with desired attribute;

const newMeta = document.createElement("meta");
newMeta.setAttribute("name", "robots");
newMeta.setAttribute("content", "all");
document.head.appendChild(newMeta);

Answer 4

After a few hours of considering all kinds of possible solutions, I eventually noticed that a much simpler piece of code could work. Instead of all this, and since I could not remove code but could add to it, I simply added this:

<meta name="robots" content="all" />
<meta name="googlebot" content="all" />

This made it worked... the bots may be feeling confused, "hey, should I index it or not, afterall?,", but it works. and that's what matters to me.

Thank you very much for your help, everyone!
