When we talk about the importance of content in ppc management... content has a bigger role to play. A ppc consultant is required to create ad-copies that goes well with the google guidelines, copy writing principles, business goals, adgroup, search queries & as per the landing page. A ppc consultant has also got a bigger task of landing page optimization.
Hence, taking into consideration the above factors content can not be separated from ppc skills. A good ppc management can not come without content writing skills. It is rightly said that when we talk about web presence... "content is the king".
