One kind digitlization color page promotion management and analysis method, storage device and mobile terminal
Technical field
The present invention relates to electronic poster technical field, and in particular to one kind digitlization color page promotion management and analysis method.
Background technology
Color page is that propagating poster is a kind of the most frequently used advertising of retailer and sales promotion information published method, in tradition side
Under the pattern of formula, color page needs a series of links such as typesetting, check and correction, printing, dispatching, delivery, it is necessary to be related to Planning Department, buying
Multiple departments such as portion, sales department, information portion, operation portion and shops coordinate.This traditional color page is by paper printing, under line
The pattern of channel granting, it has the following disadvantages:
Participating department is more, and cost of manufacture is high;The content production cycle is long, later stage change is difficult;It is small that scope is launched under line, cost
Height, the final effect of publicity are difficult to define.
To solve the above problems, it is by the way of at present:Enterprise is converted to papery color page by Edition Contains mode
Electronics webpage, the mode being illustrated in its portal website.But this mode similarly Shortcomings:
Electronics webpage needs special messenger (webpage designer) to carry out, including the follow-up of whole website aspect safeguards that operation cost is high;
Mode of operation does not form system, bottleneck in conversion efficiency be present, often because matter of time, and reduces coverage;Launch
Scope still is limited to own channel, and exposure rate is low;Effect analysis is realized if desired, also needs substantial amounts of development, cost
It is high.
Therefore, there are a kind of procedure to be developed, automatic business processing, realize the electronization of color page rapidly, issue exhibition by all kinds of means
Show, launch the generation method of the electronics propagating poster of staining effect promptly and accurately.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of procedure, automatic business processing, rapidly
The electronization of color page is realized, displaying is issued by all kinds of means, launches the generation method of the electronics propagating poster of staining effect promptly and accurately.
To reach above-mentioned purpose, what the present invention was realized in:
One kind digitlization color page promotion management and analysis method, suitable for being performed computer equipment, including for storing up
There is the database of commodity data, this method comprises the following steps:
