I have a client that owns a huge online store and he has hired me to do SEO. His previous website was slow and unprofessional so I redesigned it. He has well over 100 products that he wants featured, but has no original content written for these items. I have a "news & blog" page which has quality articles related to his business and the niche he is in. I know that these unique product descriptions will have a substantial result in ranking higher. What methods can I do to optimize the site without buying/writing 100+ articles?
