Subdomains vs. separate URLs

[coykiesaol]

I have a question if anyone can answer for me:
For SEO purposes, is it better to have separate domains or subdomains?
Any suggestions / ideas?
Thanks

Sub domains are considered as one of the best way that helps you in ranking. But the thing is that you need to choose them properly and carefully.

better to use domain on different ips.

Separate domain on separate IP address would give you lots of SEO advantage while subdomain may not give you so much.

Separate domain separate IP address will be given much more SEO any subdomain can not give much.
