Eric Siu explains how to buy an existing website that already ranks for keywords you want, redirect it to your site, and capture those rankings instantly. He gives an example of a site ranking #3 for "senior living" that costs around $10,000, letting you skip years of SEO work.
Go out there and buy a website that's already getting the traffic that you want. I had a senior living business and I saw a website that was ranking number 3 for the keyword senior living and they ranked for a handful of other senior living keywords. And so what we did was we didn't pay a lot for the website, $10,000 or so. Then we redirected the traffic and then we captured that ranking. We were then ranking number 3 for the keyword senior living and a bunch of other senior living keywords. And so that's an example of us not necessarily trying to start from scratch. We had a domain and then we redirected it and that worked out for us.
