I really suggest you go re-read that thread. I'm waiting for my coffee to kick in at the office, so I'll break out the spoon for you.
1. If your niche is weight loss, then you search "your weight loss keyword" on Google.
2. Under the search bar on the right hand side, click Search Tools. Change "Anytime" to "Last 24 hours". This gives you a list of recent posts.
3. Click on a post, and navigate to the comments.
4. Write a creative blurb such as "I was fat, now I'm not" followed by your link. Please be more creative than I am if want anyone to click the link.
5. Repeat until you hate the computer.
6. Take a walk, grab a coffee, then start over again.
From there, turn to other sources, ie Reddit, Forums, Facebook - anywhere where you can find eyes on the screen is where you want to be. Strike while the iron is hot (aka the conversation is flowing) and you will get some traffic. Conversions are a different matter but you need to learn to crawl before you can walk.
