Hi there.

I think Google is smart enough to correlate those. I have used special characters in pretty much all of my campaigns and didn't see any bad influence, since keywords are ranking in top 3 etc.

Hope this helps.

Sure thing

Well, i see why it's being reported as 503. Cause even i can see it in developer tools. the main domain has 302 redirect and then responds with 503. Anyway, for you there is gonna be no difference in terms of seo. As far as I know google ranking algos don't use outbound links as signals. As relevance signals - sure, but not really of a much impact on rankings itself.

Hi there.

_"he has removed it from GA" - _this is very weird statement, can you give me more details?

Also, if those links are broken, then why don't you remove them? or those links are inbound? if they are inbound, then you wouldn't have any impact SEO wise, since they pretty much wouldn't count as backlinks.

Hope this helps.

If you took website down, you don't have to really do anything. Go to search console, do fetch as google on old admin subdomain, so google understands that it's not there anymore, and then just wait. Google will take those backlinks down.

I see. Read my response below and just use meta robots. it will help you out.

If you want to deindex those backlinks, you also can look into Google Search Console's demoting tool, but i don't think it's necessary.
