Visual content plays a big role in the success of a content marketing strategy. We've found that The Adobe Creative Suite will set content marketers up with everything they need to lay out ebooks, design infographics, create social images, etc. The team will find themselves in InDesign, Photoshop, Illustrator, and Acrobat pretty frequently. For a free alternative, try Canva. This lightweight software makes it easy for designers of all levels to create quality visual content -- things like presentations, cover photos, ads etc. 
Premium or gated assets are typically longer form, and/or more time-intensive pieces that don't exist on a blog. They might be used to generate leads or contacts, or for brand-building purposes. These are typically created by the dedicated long-form content creator if your team is large enough to have one, but sometimes bloggers get involved too, as blog posts are good testing grounds for what performs well and is thus worth investing in.

Understanding the purpose of content is key to producing high-quality work. It's meant to speak directly with a particular audience, such as customers, potential customers, investors, employees, or other stakeholders. Content can be well-written, researched and creatively conceived, but if it isn't speaking to the intended audience, it's not doing its job.  Here are a few good examples of long-form, quality content written by Scripted writers:

There will always be tactics that produce quick, short-lived spikes in traffic and leads. There will also always be those methods that may have no business impact at all. There has been a great deal of time and money invested in growing your business to get it to where it is today, so invest in proper content marketing now and it will reward you for years to come.
Get familiar with the content writer pay scale. Many content writers starting out in their careers are not sure how much they should be paid per word. Most publications pay by word, or by hour, with a certain word count expectation. On average, content writers should be paid no less than $0.02 per a word, but may not reach more than $1 a word. Salaried positions are different, as you will be paid a yearly rate for a certain amount of work. It can be difficult to get a salaried position fresh out of graduation or when you're just starting out. Most content writers will start out working per word, or per hour.[12]
Email lists are marketer's most treasured assets -- and they're a smart way to drive traffic, conversions, and re-conversions on your content. Invest in growing your blog email subscription list for an incredibly valuable distribution arm alongside your sales lists. You can do this, for example, via lead flows that politely ask readers if they'd like to subscribe as they're reading through certain articles on your website.
Those scenarios might have sounded like a lot of work to you, especially when considered alongside marketing programs that provide more immediate gratification -- like list purchasing, PPC, or trade show marketing that deliver names and email addresses in mere minutes. Often, content marketing is used when businesses realize those programs are either ineffective, too expensive, not scalable, or all of the above. Here's what I mean, using the "infographic generator" example above for demonstrations.
