Do you advice a SaaS to use .do domain?

If you target customer base is made by young people or tech savvy people go for it. Domain extensions are basically irrelevant. Ideally, a .com is better but nowadays you usually have to choose between a terrible name with the .com extension and a good name with a strange tld extension. I choose the latter every day of the week.

It seems pretty polished to me. I looked at a couple of other TLDs available and none seem quite as nice as .do.

Seems like a great idea! Would also recommend picking up helpbasedo.com (or maybe there's an interesting .help domain as well?)

These unusual extensions can definitely work, especially if they play along with the name, eg. Thegreen.diet

But at the end of the day I think it’s not really that important. What’s important is that it’s simple, readable, memorable. The extensions plays a minor roll.

Good luck!

Personally I would not unless your target audience is in the Dominican Republic.

There is a good article here (https://www.semrush.com/blog/will-using-alternate-tlds-affect-your-seo-negatively/) listing out some things to think about with alternate domain extensions.

If you can’t get a .com/.org/etc take a look here (https://en.wikipedia.org/wiki/GccTLD) for some of the generic country code top level domains like .io/.co/etc.

Unless your name has a point in using a different extension as it has already been said in the comments don't do it.

I really like the way Paul Graham explain it here: http://paulgraham.com/name.html

And would like you to think also on your audience, how computer friendly are they? E.g. if your target audience is technical they will probably don't mind if you use a weird domain name, but if they are not you will probably run into the classic: huh, so what is this domain? You sure it's not a scam or a virus or something?. Not that common anymore but I still run into it every now and then. (Can't assess how technical e-commerce owners are tbh, my knowledge on that is quite limited)

Also, any reason not to use a subdomain? If your help documentation is going to be a different app.

I would not use .do domain name unless it is a great hack e.g. un.do. It is better to use .io or .co if .com is not available.

".do is the country code top-level domain for the Dominican Republic." With the recent hack of the top-level domain registrar for Greece, that is one thing to take into account.

Otherwise what we found out is that it was really difficult to get Google-verified for a .co domain, and as a result we couldn't get a DigiCert "green bar" TLS cert.

Can't say I see many .do domains out there. Seems .io is still the cool kid on the block, but at the end of the day, .com still reigns.

Perception would probably be fine considering that helpbase.com isn't an active site. There's always an uphill battle when you're not using a .com, especially for folks typing in your domain. I'd probably try to pick up helpbasedo.com as well just to be safe.
