Educate me........What is Bum marketing ?
It's basically similar to article marketing.
You write a nice article about a product you are promoting, and stuff it with affiliate links. You do this a good hundred times, manually, or with bots and then get the articles ranked.
Then you get clicks > conversions > sales.
Does it still work now?
I don't think so. I think there are other ways to make money which is better than this.
Why? Because you are relying too much on the articles on the article websites.
Google is Google, and knowing that, you don't know when they will release an update. Instead, of posting all the articles to article sites, you are better of creating a website with different articles on it.
BUM marketing used to be decent, but now, its too risky. A simple algorithm change could lead to your articles getting removed by an editor as such and that can cut of your main link to making money. Too risky in my opinion.
