Hello. I know that the best TLD is .com. I found a very good domain for my new blog but only .WS is available. So i am not sure if .WS is good for optimisation. What about .org, .net and other TLDS? Thanks.
Preferably, .COM is very easy to remember and it has a shortcut key so that a user can hit "sitename" and press Ctrl+Enter in order to append 'www' and '.com' to the front and the end respectively. When it comes to the other tlds, I prefer the name of the website to be extremely catchy. Other than that, quality of the content provided shud be high so that the user remembers your site in particular. Also, post some catchy images saying the reader that it is ".ws" but not a ".com" website
If you want to rank at Google.com then I would highly suggest a .com, .net, .org domain. While Google's ranking algorithm is TLD agnostic for non-country specific TLD's wishing to rank in Google.com, country-specific TLDs like .co.uk are automatically assumed to want to rank in that country's specific Google index like Google.co.uk. If you own a .co.uk domain you cannot even set your Geo Targetting preference in Google's Webmaster Tools. It's automatically assumed to be United Kingdom. .ws was previously for Western Samoa. But I believe it was recently "repurposed" for some generic "website" extension. Not sure how Google will treat that TLD. But even if they do treat it similar to non-country specific TLDs like .com, .net, .org, etc. it will likely attract far few inbound links naturally. And if you manage to get it to rank in the SERPs then it will attract far fewer click-thrus than a .com, .net. or .org would get. If you want to rank in Google.com, I would rethink buying some .ws or .me domain, and instead settle for possibly a less than ideal .com, .net, or .org domain because from a user's perspective they appear in the eyes of most to be a more legitimate web site. When people don't know your site (i.e. it's not some brand that people recognize) it's hard to convince them to click on your entry in the SERPs. You need every bit of credibility you can muster, and the TLD you pick can help. I'd settle for a less than ideal .com over an ideal .ws any day.
If you target is mainly for direct customers, then I suggest .com If your main concern for traffic is from search engine, then I suggest any suffix will do. As long as with good onsite and offsite SEO accomplished, your site will be success.
