Excellent contribution!

On top of that, I always recommend people to keep a good and constantly-updated blog, because it is easier to get backlinks for a great piece of content than for your money pages. This is the best and easiest way to improve your rankings and start getting more organic traffic!

Furthermore, one should treat the blog as a way to educate new visitors and create a strong bond with them, so it is easier for them to buy from you and remain loyal.
