If you decide to hire someone to write your Build My Rank posts for you; you need to be careful who you hire. Hiring someone who doesn’t speak the English language well is just asking for trouble. Just because someone can speak English doesn’t mean they can write well. If you didn’t pay much for the writing you may want to take the time to proof read everything that person wrote. You will be wasting your time and your money if you have to rewrite it and submit it again.
If you get the chance take the time to interview the writer online or over the phone. Someone who has experience in writing for Build My Rank type websites will know what keywords are. They will also know that each article must be at least 150 words long and the keywords used must be bolded so the editors can find them.
