Rewrite articles provided by changing one sentence at at a time, without changing the content of the sentence.
For example the same sentence adjusted would be like this:
?
1:? Offering toll free phone numbers to customers bring in the sales ??" but it is also expensive.
2:? Toll free phone numbers bring in the sales - but they are also expensive.
3:? Direct marketers use toll free phone numbers to bring in the sales - but they hate the cost of offering them.
4:? They are expensive to offer, but essential to make the sales: toll free phone numbers.
Articles are of varying length - up to 1000 words. SEO words must be kept in mind, usually we require 3 - 5 versions of each sentence.
