Dropshipping definitely seems to be more involved as far as getting all the pieces of the puzzle working for you and advertising and managing shipping, etc. If you are not a good writer or like writing, dropshipping may be more your cup of tea. Affiliate marketing is a great option but you must be willing to do a lot of writing. If you can handle the writing, then affiliate marketing is a much better option. I chose to get started in affiliate marketing and have learned a ton since!
Focus on reviewing products that fall within your niche. Then, leveraging the rapport you have created with your audience and your stance as an expert, tell your readers why they would benefit from purchasing the product you are promoting. It is especially effective to compare this product to others in the same category. Most importantly, make sure you are generating detailed, articulate content to improve conversions.
