How do you lot be an affiliate marketer?

Pick a narrow topic you can write about for a year without getting bored, then find programmes for products in it. Amazon Associates is the easy start but the commission's low, and you need 3 qualifying sales in your first 180 days or the account gets closed. Networks like Awin, Impact and ShareASale, or brands' own programmes, usually pay better. The actual work is content: honest reviews, comparisons, "best x for y" pages people search before buying. Disclose your links. Expect months before it makes anything, most people quit in that gap.
