What can we help you with?
I've seen review sites with product, service and price comparisons. What will my customers expect from online services like these that will give them financial savings?
They expect that you can give them a reasonable price, keeping it affordable for others. The price match also gives some proof that it is actually better than the other companies.
It is a space where they can see if the product is actually good before buying, this gives them a better opinion and see what others think about what they are about to buy.
You should search comparison sites for your own products or ones like it. It gives you free marketing research in terms of the competition and what customers want.
