So what does it take to make a killing selling PLRs? Theoretically all you need is the ability to research and write quality articles. But it's usually a bit more complicated than that.
The first thing you should do is find a good niche to get into. A good way to do this is to search on any of the various popular search engines such as Google and Yahoo and use their keyword research tool to find out what people are actually searching for. Type in a word or words pertaining to a product idea and get new ideas from the results.
Next, start writing. Focus on using the words or phrases from your keyword research that have shown high search volume. Remember to use correct grammar and spelling. Aim at writing approximately 400 to 600 word articles.
After your articles are done, bundle them up and sell them as packs of 10 to 20 or even as much as 100. Keep in mind though that usually the ones in smaller packs are usually ones of higher quality than the ones in larger packs. Also, make sure you set a limit as to how many packs you sell for this will preserve the value and thus the price.
Last but not least, it's time to market to you consumer, website owners. One method is to post of classified ads. Ebay is a great place to start. Setting up a website can also help you make some sales. And last but not least, another great way to market is to advertise and participate in forums related to the topic of interest. The forum in conjunction with your own website makes a great combination for marketing and sales.
