Your online reputation falls into two main categories. That is what your customers see and what Google sees.
Your Online Reputation According to Your Customers
When a potential customer finds your business online, the first thing they may do is look up some online reviews. Reviews are a great way for a potential customer to get some insights how their experience may go based on previous customers feedback.
To ensure your reputation is looking it's best ensure you ask for feedback from satisfied customers. Many customers will not take the time but the unfortunate thing is that if people have had a bad experience they are much more likely to leave a bad review. Good reviews normally go unspoken, hence why it is good to ask.
If you only have a few reviews left for your business, a negative one can have a large impact. Especially if it the most recent too. In this case try to learn what led to this unhappy customer and see if you can improve your processes or practices to prevent the same thing from happening again. Also try harder than ever to get some positive reviews to bury this one deep below many more recent 5 star reviews.
