As William Alvarez says, Google will provide suggestions to correct typos. But in many cases, that won't happen or won't help.

For example, if your brand name is a creative misspelling of a common word, then the auto-suggestion will actually work AGAINST your brand name, since Google will assume that people searching for you are making a mistake.

If your name is frequently misspelled and the typo variants are available to register as domains, then you really ought to snag them and forward them to your website.

If those variant domains are more expensive or unobtainable, then the decision becomes much more complicated. In those cases, I can help as a broker with domain procurement.

Sometimes (I regret to say) a rebrand really is the best option. There too I can help as a namer. But that doesn't mean I'm going to steer you toward an expensive solution. There is no one-size-fits-all answer.

I will add – for the benefit of eavesdroppers – that this advice applies to many cases apart from typos. Domains often have variants that are spelled correctly. Many websites are leaking traffic to these variants even though they don't realize it. And some of them will pay through the nose for domain acquisitions down the road.

Anybody reading this who doesn't know what I'm talking about really ought to ask. Send me a message with your domain name, and I'll tell you if it is or is not in conflict with other domain variants. If it is, we can set up a call to figure out what to do about that, if anything.
