I feel that how to predict book buyers which is driven by book buying experience and the publisher's credibility ( loyalty) factors which will influence the any book buyer whose make final decision to buy the book from the publisher. As a publisher, a major goal is to extend whose readership and extend whose readers' influences, but where to start? How do publishers understand and serve diverse readers and decision makers in different countries? Whether can readers find the kind topic of book from publishers only, when find the kind topic of book from the university libraries or public libraries? Hence, due to offline and online publishing industry competition is high, global publishers will need to develop a sales plan to satisfy readers' reading taste. For publishers need to conduct book exhibition activities, visit different author's decision makers to research what who like to write negotiate terms to publish books with individual authors, secure sales and manage orders etc. different regulations of publishing to every author.I recommend online or offline publisher ought concern how to publish every book before they decide to sel their every electronic book or paper book to any countries' readers. The marketing strategy includes to develop plan every book sale projection, SWOT ( strengths, weaknesses, opportunities, or threats ) to every book to be published to the country's readers to implement the plan. Book sales program, email communication marketing, lead generation to analyze the results, eg. every book purchasing trends, customer profiles, marketing sementation for every book to follow up and bedrief: Measuring ROI, setting priorities and develops tastics, finally customer needs analysis foe every book sale, it includes GAP analysis, ebook online library visits numbers to experience the ebook and focus groups. The, it is cycle to the develop plan again. Thus, if the publisher can have a better understanding of pricing strategy plan which can create price plan to be strengthed changes or cancelled for every paper book or electronic book sale marketing price strategies. Bringing potentially and disastrous reading experience to readers, this factor can be one good method to increase reader number and book sale price and sale number method.
