How to incorporate my own blog into my website?

Hey guys.

I have my site set up and plan on having a blog as part of the site. It is a product my company is selling and marketing.

I want to have both the selling/contact us/products/prices and planning/about – all on the site and also a section called “blog” for all my blog posts relating to the product.

Many sites already do this.. I have been searching online and cannot find a solution specifically for this.

Help would be very much appreciated!
