Market share is the percent of sales a specific product attains in relation to the total sales of all similar products. For example, Tide may have a 30 percent market share in the domestic detergent market. Holding or maintaining market share is a defensive strategy that seeks to protect the market that has already been conquered. Managers should defend their markets against competitor attacks.

Introduce new, improved products. Innovative products can help maintain or increase market share.
Safeguard your distribution channels by keeping the shelves full of popular and new products.
