How much would you pay for that?
That would be 80 articles every month across 4 niches.
Food for thought:
$10/month would be $.12 per article
$20/month would be $.25 per article
$30/month would be $.37 per article
$50/month would be $.62 per article
$100/month would be $1.25 per article
What if these were 400-500 word articles, accompanied with spintax versions ready to spin?
