If your website, signage, ads and marketing material don't match then it's time to redesign them. Communicating a consistent brand message will keep your brand in the minds of your clients.
You don't know what you want
If you haven't mapped out your branding strategy on a 1 year out to a 5 year basis then you don't know where you're going. And more importantly your client won't know either.
You're having trouble connecting with clients
If you don't know who you need to connect with and where to find them, then you may spend time and resources building relationships in places that won't drive the business results you need.
Only Talking about Yourself?
It's important to strike a balance between being social and a self-promoter. No one wants to hang out with the person who is always talking about themselves.
The Competition Looks Better than You
If your competitors' message and look outshines yours then a change may be in order. The idea is to stay ahead of the curve without copying your competitors' marketing for the sake of keeping pace. Be original and an expert.
