"We have used many content freelancers, and Micah is one we keep going back to!"
"Micah did excellent work! Top-notch writer. I look forward to working with him again."
You probably already know this - a series of well-written blog posts can be an invaluable resource for technology companies.
Engaging blog content can help you to
- generate traffic and increase leads,
- build relationships with your customers,
- and position your business as an authority in your field.
Stop for a moment, though, and place yourself in the shoes of your target audience.
Let's say you've got a fresh business idea but very little technical know-how. So you're looking for a tech company to help bring your idea to life.
You do a bit of research to find out the best solutions and narrow down your options to just two.
Checking out the blog of the first company, you find a lot of seemingly authoritative posts, but you barely understand what is being said and how exactly it applies to your project.
The other company's blog, however, contains a series of clear, understandable posts that clearly explain how their services could help you achieve your goals.
Which company will you want to develop your idea?
Undoubtedly, you'd be drawn to the company with the easy-to-understand articles.
This mental exercise clearly illustrates the importance of keeping it simple when discussing complex technical topics on your company's blog.
The average non-techie should be able to grasp the information on your blog quickly and make decisions based on it.
And the key to achieving this involves:
- taking into account the existing knowledge of your target audience,
- delivering just the right amount of detail to help them accomplish their goals,
- and tackling their fears and objections.
This is precisely what I aim to help my clients achieve.
I specialize in:
- crafting simple yet informative articles on fairly complex technical subjects
- writing well-researched guides that help readers solve challenges and become proficient with your tools and services
- producing authoritative content that demonstrates competence and expertise
- and creating helpful content that builds trust with readers
I'd love to learn more about your company and how the services you provide empower your customers.
If you'd like to talk more, shoot me a message and I'll do my best to respond ASAP.
Micah Bello.
