I'm currently on SiteGround, which means I'm on their public nameservers. I wanted a unique private nameservers so I created a NS records in the DNS zone, And forwarded my domain to it.
Here's example:
NS RECORDS: NS1 >> 00.00.00.00
| NS2 >> 00.00.00.01
Then submitted the nameservers: NS1.example.com
| NS2.example.com
So after that everything worked fine but I could noticed that my site doesn't appear on Google anymore. but on Yahoo and Bing it does.
I thought this might be the reason because other websites I manage which use the public nameservers of SiteGround do show on Google..
So, Does Changing From Public Nameservers to NS record can harm Google ranking? I have just switched back to the public nameservers but it can take weeks till my website show up on Google again, if it really the problem..
