does anyone know where i can find articles legally to re-write and submit to article directory? I have niches that i want to write about if i have no idea of what to write.
Any PLR, anything that's not copyrighted (in the public domain), stuff thats out of copyright ('the bible'), stuff you create yourself.
PLR tends not to be free (as per your post title), but it's a good way to get going. For works in the public domain, you can check out Project Guetenberg here: http://www.gutenberg.org/wiki/Main_Page There are 1000s of works and here's an example of the usage allowed: Pretty cool site. It offers multiple languages too. I wanted to try learning Tagalog (Philippines) and there are tons of books in that language there for free.
PLR articles can be had for free if you join certain email lists and membership sites. I have managed to accumulate something like 11,000-12,000 PLR articles on my hard drive and have more material than I could possibly rewrite and publish in any reasonable time frame without doing some major outsourcing. I have never had to pay for any of these articles except in the form of time that it takes to organize them all. The real challenge with finding or writing articles is to figure out exactly WHICH articles to publish, who your target audience is, and how to monetize the article pages for that audience. Of course, you may also need to "tweak" the articles for the right keywords so that you can attract some good traffic to the pages.
as far as i know you should go for PLR articles..they are real cheap...i never bought them...but i tried to write...i did a great research on this...but at last didn't do it..!!
PLR articles are the best way to do this. Just search google for free plr articles and you should have plenty of sites to choose from that give away the articles in bulk. Many of them require signing up for their newsletter, but it is still free
