Description:
Many companies are already utilizing blogs on their company website, but those who haven’t yet would be advised to do so. The beauty of a blog article is that it doesn’t have to be long (in fact, if it’s too long, you’ll lose your readers’ attention), it doesn’t have to be written using a lot of technical jargon, it shouldn’t take very long to write, and you can include as many SEO keywords in the article as you or your SEO company sees fit.
