Hello, I need advice. are there any problems If i buy domain.ws, .info .us . net. org for SEO. I mean domains with .com are better for SEO than these i've mentioned ? Are there any problems to get sites higher than .com in google or Yahoo ? Thank you Regards Greg
it's no matter dot com or dot net domain for SEO, sure always better if you can register a dot com domain.
it will matter a lot while selecting domain name. you need to take care of target market and select domain accordingly. It will be more difficult to get ranking for other tld than .com in google.com for niche keywords. it is advisable to go for .com
SEs say that they don't care about the TLD extension. I have sites on 3 different TLDs and have not experienced any real difference.
