PLR articles, or private label rights articles, are a good way to add useful, interesting, search engine friendly content to your website.
If you're building a string of websites, or a large site, writing a blog or distributing articles to article libraries, you need a lot of articles.
It's time-consuming and tedious trying to research and write all those articles yourself.
You can hire writers at places such as elance and RentaCoder, but if you've tried that, you'll know it can be done but it's not as easy as it sounds.
So you need a workable shortcut.
To help website owners in this dilemma, several websites provide well researched, solidly written private label rights articles.
These membership sites enable you to get hundreds of PLR articles for as little as 15 cents or 20 cents each.
They're a fantastic bargain. I belong to several PLR article sites.
You don't want to use articles that thousands upon thousands of other sites are using, so membership to these PLR article sites is usually strictly limited.
Rewrite for best long-term results
If you join some of these membership sites, I strongly recommend that you do at least a little rewriting.
You'll want to tweak and optimize the articles to help search engines find them. Often the articles have not been written with any particular keyword density in mind.
This is a good thing. It's means your articles will be unique. You can also add your own tone and personality.
Some webmasters in a hurry take a minimalist approach, leaving the article untouched but write a brief introduction and then add a brief comment at the end.
Others use RSS feeds to add content to the pages.
The more original and unique your approach, the more likely you are to have good long-erm results.
Some rewrite up to 60% of the articles and others play it safe, merely using the articles for inspiration and totally rewriting them.
Whatever system you use, it's much easier improving a ready made article than writing a brand new one entirely from scratch.
Good sources of PLR articles
Here are some good sources of private label rights articles.
Food articles, recipes, etc. Every month, Wendy Cook will provide you with 30 new food articles, 30 new recipes, 5 product reviews, and a 5 to 10 page special report. You can use this special report as an incentive for people signing up for your mailing list, or as an incentive to buy something. Plus you get a professionally designed ecover graphic for your special report. You also get access to affiliate program recommendations and other resources to help you succeed with PLR content. I've seen inside this membership site and seen the quality. For anyone in the food niche, this is exceptional value.
Stefan Everaet provides very high quality articles each month, plus superb graphics. For example, topics covered have included weddings, web hosting, wine, credit cards, birds, dogs and cats. He provides not just articles but complete niche content packages. Stefan provides very high quality articles. I recommend this site. It's excellent value.
UPDATE: Now hugely improved. You can choose between several monthly subscription levels. For example, if you're interested only in travel, you can spend your credits only on travel-related content.

How to avoid duplicate content filters
Search engines inevitably are getting tougher and tougher on duplicate content. If you ignore this fact, you risk seeing a whole lot of your work go down the drain.
If you buy PLR articles never simply use them unchanged. That would be asking for trouble. Rewrite articles to avoid duplicate content filters.
For best long-term results, ALSO do your own research, add your own comments, add your own tone and personality, and make your site genuinely USEFUL so that people will want to recommend it.
