How much should I be paying for Articles?

As in, per 100 words.

Cause I've seen some writing services on these forums, and I'm thinking; what sort of price (per 100 words) is usually going to be good
for authority site purposes?

Just wondering since I'm such a noob but I'm planning on changing that .

I also want to know, where to get High Quality articles?

$3+ .

You pay whatever the writer is charging you.

Depends on the topic and if it takes experience to write about it.

Basic reviews are just fluff, but you need an expert to write about something like enterprise IT security so you're going to pay more.

Sales copy costs the most, because you want compelling content that sells and you're making money off of it, so you're going to pay more.

Don't pay a fluff writer for 10 articles at $10/each just to throw junk on your site. It's far wiser to pay an expert $100 for one awesome article that connects with your readers.

if you are in need of high quality articles no way you need to spend few extra pennies on it.. or as archon10 said, pay the writer according to the quality of their article.

It really depends on the writers, some charge around 6-8 and the content is really good

I'd suggest $3+ or refer few posts on content writing section.
You'll figure out the rate Enjoy!
