This article is very helpful to a start up. Although we cannot cover all of reasons in marketing mistakes, here are some popular pitfalls that many start-ups meet.
Target wrong audience
Many start-ups fail to answer the question:"Who am I marketing to?" It sounds like the simple mistake to make. Your customer base should be determined in business plan, as well as their behavior, media habits also are understood clearly by business. Take cost and resource to invest in R&D, (e.g: market research). Only then, you can approach right objects.
Show partial price
Because price is elastic element; you have to show the full price of your products or services in your marketing, not just a small element of the price. Price promotion is just one way to generate interest in your business. Don't exploit and only show unclear price for them.
Not showing a point of difference
With new business, each service or product offerings need to have something in competitive advantage to compete with others. Therefore, analyze and find out their strengths and weaknesses. Your advertising should show consumers how you will meet a need that is currently being overlooked.

Stuffing up your offers
A new business, sometimes, often try to secure a customer base by providing instant loyal rewards. It can be a good tactic, but treat carefully. You should make sure that targeted offers reach their actual target, and you must honor about it without damaging your bottom line.
Making search term errors
This reason is suitable with online business, because search term on Google is quite important. Search marketing is an increasingly important part of communications and you need to think carefully about how you are represented on Google and other search engines.
Not integrating your message with other channel
When you do marketing campaign, especially media to approach customers. All of things need to be integrated, messages in all media channel should be consistent in word, sound, color, template.These will create good appearance for your business and help customers easy remember you.
Butting into social media conversations
If you want to market yourself via social media, make sure you're being honest, genuine and conversational. The audience will respond more positively to this than being bombarded by one-sided messages.
Spamming customers
Spam customer is one way of bothering them, and it mostly reduces their business image. So, don't infiltrating online conversations with unwanted marketing, and don't send the message into unwanted customers.
Sloppy execution
Remember, your marketing is the visual representation of your business. As a start-up, market awareness of you is extremely low. The only impression people have of you is the ad that they briefly glance at.
Spend the time and money to come up with marketing campaigns that not only grab attention, but also accurately represent your business. If you are a premium, exclusive company, your marketing material should reflect this. If you have a price-based proposition, the style and tone of marketing should be entirely different. Consider using outside help to make sure your strategy and execution are consistent and of decent quality
