Werbung dient dazu, auf bestimmte Produkte, Angebote oder den Markt im
Allgemeinen aufmerksam zu machen. Sie kann über verschiedene Wege verbreitet
werden, etwa das Internet, Zeitungsannoncen oder auch per TV/Radio.
Im Gegensatz zu Rabatten (die zeitabhängig am besten funktionieren) ist Werbung
stark von der Zielgruppe abhängig. Insbesondere in der Kombination mit anderen
Marketingmaßnahmen kann sie so ihre volle Wirkung entfalten.

Analysen, die für Werbung nützlich sein könnten:

<p>
Gibt es eine Produktgruppe, die sich besonders gut verkauft, so sollte unter
Umständen über die Erweiterung des Sortiments innerhalb dieser Gruppe
nachgedacht werden.
Im Umkehrschluss dazu bietet sich an, schlecht verkaufte Produkte, welche keinen
hohen Gewinn abwerfen aus dem täglichen Verkaufsgeschäft wieder zu entfernen.
Dies verringert die Bildung von „Ladenhütern“ und schafft Platz für neue, sich
besser verkaufende Produkte.

<span class="card-title center">Rabatt</span>
</div>
<div>
<p>
Rabatte können z.B. an Tagen angeboten werden, an denen nur wenige Kunden
erscheinen. Dadurch wird einerseits an dieses Tagen oder Uhrzeiten das
Kaufverhalten angeregt, als auch der Andrang an anderen reduziert. Dies dient
insbesondere der Entzerrung des zeitabhängigen Kaufverhaltens.
Des Weiteren können durch Rabatte weniger gut laufende Produkte in den
Vordergrund gerückt du vergünstigt angeboten werden.
Zusätzlich dazu können sich gut verkaufende Produkte mit einem (vermeintlich)
verringerten Preis versehen werden. Dies kann beim Kunden den „inneren
Schnäppchenjäger“ wecken und dafür sorgen, dass er sich dieses gute Angebot
nicht entgehen lassen kann.

Es gibt bestimmte Produkte, die werden häufig zusammen erworben. Sind diese
Produkte quer durch den Laden verstreut, so müssen die Kunden zusätzlich zu
ihren Wunschprodukten auch an anderen Auslagen vorbei und die Anzahl an
Spontankäufen eben jener weiteren Produkte steigt.
