The number of different categories of a company is referred to as
width of product mix. The total number of products sold in all lines is referred to as
length of product mix. If a line of products is sold with the same
brand name, this is referred to as
family branding. When you add a new product to a line, it is referred to as a
line extension. When you have a single saleable item distinguishable by size, appearance, price or some other attribute in your product line, it is called SKU-Stock Keeping Unit. The marketing jargon for adding a product that is better quality than other products in the line is
trading up or
brand leveraging or
up-market stretch. A line extension of lower quality is called
trading down or
down-market stretch.
Trading down may reduce your
brand equity by gaining short-term sales at the expense of long term sales. The jargon for "stretching the line" in both the directions is "two-way stretch".
Image anchors are highly promoted products within a line that define the image of the whole line. Image anchors are usually from the higher end of the line's range. When you add a new product within the current range of an incomplete line, this is referred to as
line filling.
Price lining is the use of a limited number of prices for all your product offerings. This is a tradition started in the old
five and dime stores in which everything cost either 5 or 10 cents. Its underlying rationale is that these amounts are seen as suitable
price points for a whole range of products by prospective customers. It has the advantage of ease of administering, but the disadvantage of inflexibility, particularly in times of inflation or unstable prices. ==See also==
