There are tons of articles on the web that you have access to. They are called Private Label Articles (PLR). PLR's are prewritten content that you can use on your website. Most people charge a small fee to use their PLR and usually limit the number of that particular article they sell.
FInding PLR's
To find PLR's you want to do a search in Google. Here is an example for affiliate marketing:
I used a broad Niche to help explain how this works. Your results from the search should look something like this:
You can also find many other articles prewritten, however, you want to be sure to rewrite them in your own words. Never put a duplicate article on your site. Change the structure, the wording and the presentation of information and you will be fine.
Once you hit enter for the search you should get a list similar to this:
Both PLR's and other articles are a wonderful way to come up with things to write about. You never want to use them word for word. That would be plagiarism and duplicate postings.
Whenever I use an article like this, I write an outline on the main topics discussed. Then I look at other articles to see if they have any other topics I may have missed. By the time I have read several articles, I feel I am comfortable enough to write the content information on my own.
CAUTION:
As I said before, DO NOT post any PLR or article as it is written when you find it. Make it your own article.
NEVER use an article rewrite program. They never make sense when they are done. You are the best rewrite there can possibly be. I have fun some days just playing with the different ones on the web to see what they come up with!
