I tend to do this with businesses.

I find a set of keywords, where I guess the niche has money + very little access.

The register a domain which relates + is catchy + easy to remember.

Then I completely ignore SEO + searches, because there are none. This means zero competition + using offline marketing.

I do offline marketing by speaking to groups my target niche/audience attends.

Then continually drop the domain name during my talks.

When I say drop the domain name, I mean the domain name as a phrase, not the actual domain name... so...

Find use a domain name which is a phrase you can mention repeatedly to gain mind share traction in people's minds.

Then speak at related Meetup + conferences + networking group events.

After a very short time, you'll start getting exact match searches for the domain name (phrase) you drop in your talks.

This may seem like a lot of work.

It is.

And, to me building $1M dollar businesses this way has worked every time. Other approaches I've taken have never produced the same large effect, as speaking to groups.

Side note: Keep in mind. When you speak to a group. If you wow your audience, they tell other people in their niche. So you may speak to a group of 30 + reach 1000s over time.

This means, to me, I speak with anyone who asks. No group is to small, because who the people in the room know, is anyone's guess.
