I work with startups and entrepreneurs looking to accelerate growth with marketing powered by storytelling and strategic planning. I help startups establish their core story and then create roadmaps for them to connect with the right customers using the right marketing channels to meet their goals. I mostly work on a three to six-month basis. Many of my clients have been financed by Canada's leading VCs.
Before you do anything, start with identifying why you want to do online marketing and your goals. Then, you should explore target audiences - how do they make purchase decisions, where and how do they get information online, etc. And a key part of marketing online is having a Website that performs (e.g. drives lead, sales, downloads, etc.) if you online marketing performs well - you're wasting your time otherwise.
How about creating content that provides insight and advice about cellphone maintenance and repair, as well as apps that people can use to get more value from their cell phones. This is "soft selling" as opposed to trying to get people to make a purchase. You could also use social media to solve problems and answer questions.
It depends on what you want to get out of re-investing your time in the blog. It's not about the traffic but whether it meets your goals - e.g. love for writing, business development, etc. The reality about blogging is doing it well takes time, effort and creativity so think hard before diving back in.
In the short-term, it comes down to the basics:
1. What makes your product unique or different?
2. Who are your target audiences?
3. How can you solve their points of pain?
From there, you craft a story (aka marketing) that meets the needs of potential customers. You need to make it easy for people to recognize that you can meet their specific needs, and there are clear benefits.
Once you've gone through this exercise, it's a matter of applying it to different channels (e.g. Website, direct mail, email, advertising).
You need to start by identifying why your product is unique or different, and the reasons customers would be interested. This provides the foundation for your Website, and sales and marketing collateral, elevator pitch, etc.
Next, I would focus discover your core customer - who's going to buy it, what are their needs and points of pain, what's the buying cycle, where do they find information, etc.
Third, you try to get business traction by combining your story with your customer personas. Hopefully, this starts to get your business traction, which could attract investors.
