is .co or .io better if you can't get .com?
IMHO: .io if the site is about data/file interaction (providing info, getting something out of it) interaction.
.co if it is about a service where the service itself is the product and not a "upfront definable deliverable".
🤔 makes sense?
Could you give me an example of "upfront definable deliverable"? because I'm also considering .co, and I wonder if I should go with it.
I'd say it depends on the niche. From my experience .io is more associated with techy-techy products. Whereas .co is more of a generic domain.
Other people may have a different POV, tho
I already asked the similar question recently, and @manuelfrigerio gave me an answer. I hope it helps you, too!
