I am getting 403 errors in semrush


Hello

When I audit my help center site with custom domain, I am getting too much 403 errors.

I guessed it was robots.txt issues.

But I couldn’t edit robots.txt in my help site in intercom.

How can I edit robots.txt? or how can I fix these 403 issues?

Please help me.

Thanks.

Hi @ozdav97 !

 

I’m not fully understanding the situation that you’re running into. I don’t know what you mean when you reference ‘robots.txt’. You’ll need to supply more clarifying information around what you’re trying to do and what you’re seeing.

My one thought based on your message above is that those 403 errors mean that you don’t have access to the Articles. Do you know if you have Audience Targeting on for those Articles? If you do, then this might be the result of trying to access articles that your Intercom User/Lead/Visitor doesn’t have access to. I would look into that first.

Hi, Jacob

Thanks for your reply.

I added semrush.com screenshot.

As you can see, I am getting a lot of 403 errors from help.chain.ccom which supported by intercom.

I have no idea how to fix this issue.

Can you please take a look and give me an advice?

Thanks.

Hi, 

 

We have similar issues with the Help Center. Crawl activity has dropped down significantly since last week. The /robots.txt file can’t be accessed directly. 

 

Custom Domain settings look good an the actual Help Center looks fine on the custom domain. The Help Center isn’t new, it was created 5 years ago.

It means that KB articles are no longer appearing in search results if you Google them. This needs fixing, please share an update soon.

How can I edit robots.txt? or how can I fix these 403 issues?

You can’t directly edit robots.txt in Intercom. The 403 errors are likely caused by permission issues. Make sure your help center articles are set to “Public” and your custom domain is correctly configured with SSL and DNS. Also, check any firewall or CDN settings that might be blocking access. If the issue persists, contact Intercom support to investigate server-level restrictions causing the 403 errors.
