How do you turn customers into brand ambassadors?

make them feel valuable and give them the best customer service and after service that you can.

I would say by making your products must-haves.
People will start buying them, using them, talking about them etc.
and before you know it your customers become your best brand ambassadors.

Heard about "When in Rome, Do like the Romans" its as simple as that! Forget product for the time being, forget all strategies, just focus on Human Element.
What makes your customer buy the product is not because its available its because the human connection that takes place at the counter.
Wholesalers, retailers or any other medium from where your actual customer picks up your product, Invest for on that particular point of sale.
That is the only reason companies like Coke, Pepsi and many other showcase human feelings and elements and gain high endorsements from public and common individuals

Hi Reem Boudraa, Thank you for Endorsing me in my Skills and Expertise :-) Have a Great Week ahead!

I would say make your products unique, provide them free trials or promotions and provide them good customer support.
Customers will definitely spread positive words about your brand and become brand advocates.

20 80 rule is applied here that 80% of the profit is generated by 20% of the loyal customers, so these 20% of the loyal customers can be the brand ambassadors by some loyalty program or membership scheme.
If they are delighted they will create good word of mouth (WOM) for the brand so is better on work in these 20% customers rather then considering all the potential customers.

Give them something free when they dont expect it.
