It doesn't matter at all. But if you want your visitors to visit your site by simply typing the name without the extension then dot com is the best for you. A dot com website is easily suggested with the word of mouth than the others.
.com is more valuable. For SEO, I believe, google.com treat .com better, even though there is no evident.
I think you got a general idea from all the responses. Concluding .com: Popular, easy to remember, difficult to find available names, browser type in is still .com favorable, No SEO advantage .co: No so popular compared to .com, easier to get domain names, No SEO advantage However I find .info domains a lot harder to get rankings
Lots of people claim google gives equal benefits to all domain types. However, how do you know that? There are plenty of reports of people having trouble ranking their .co-sites. So how do you in fact know that google gives them equal treatment?
The .com always wins because it's very popular, but I would like to see what the influx of country domains may mean
He has said just the opposite. "At the end of answering this question he (Matt Cutts) did admit that they might have started to look at particularly cheap (and spammy) TLDs differently than other TLDs–or they might start considering TLD in their algorithm if they’re not already doing so." From the Domain roundtable conference. SEO.com is the source.
I know. That is not the CURRENT scenario. "they might start considering TLD in their algorithm" is the phrase used. In the future we really cant predict what will happen with Google alhorithms
.com is the most popular domain extension so the possibility would be more visitors will visit your site.
I didn't say it general, I said it I meant it. I meant google.com, not google .com is TLD so, google.com would treat it better .co is country domain, so google.co will treat it better. if it ever exsit. That is what I meant. Did anyone said about it before me? no, right. I put google.com there, not just google. This is my experience when i working on my site under different top level domain and country domain.
You left out the part after it though "if they’re not already doing so". This is a quote from 2008 so you can be pretty sure they are at the very least doing it by now.
