Right now, looking at her publicity, will I make it? But I'm not sure how she got rich and all that. I'll do anything for millions of readers even if it means bleeding to death! I'm just a noob. How did she do it?
I did a case study on these for a marketing/PR class. You can Google some information to figure out the marketing plans and strategies for each book.
Here's the thing. Like others have mentioned, yes, she wrote a great story that people wanted to read. But marketing and PR did a LOT to make it the phenomenon that it is. However, the books (story structure AND the story elements themselves) allowed marketing to do what they did. Plus, Rowling contributed a lot.
In the early years, she spent a lot of time doing book tours and readings, many of these on her own. Not only did she spend the time working on these, you can find a lot of comments about how well she interacted with her fans, how nice a person she is when it came to discussing matters with book managers. Her personality in general had a lot to do with it.
The initial spread was based on word-of-mouth. Then the sales starting coming in, and marketing took advantage of that to create some interesting PR gigs. She toured the UK in the Hogwarts Express, for example, again meeting fans and signing books.
By the time Goblet of Fire was released, she already had a big fan base and the first three books were the top of the New York Times bestseller list.
Again, marketing took advantage of this. They sent out press releases to announce the book was finished. They sent out press releases months later with chapter releases and page count. Months later, a press release with the title. Another with book art. Finally, the release date. And still more ... press releases stating that the ending of this book was so extraordinary, it was going to be printed in the dark, ensuring no spoilers.
All these press releases, JKR interviews, etc., made sure Harry Potter was staggered in newspapers, magazines and blogs in the years between releases so nobody forgot about it. Again, JKR herself was integral here. And to capitalize on all the press coverage? Midnight book release parties. They sent starter kits to bookstores encouraging them to host the parties. Everybody wanted their hands on the book at midnight, ASAP, because they were marketing this secret so well, everyone wanted to know what it was the second they could.
With the following three books, they kept up the air of mystery. Basically, each subsequent book oversold the previous--so marketing wasn't competing with other books, they were competing with
themselves. They pushed themselves to do something bigger and better each time to keep the midnight sales climbing. Each book had a different campaign. The fifth book's campaign revolved around the fact someone would die. Again with the sixth. And the seventh was that it was the cap to the series--and whether or not Harry would die.
What became interesting is that in the later releases is that their campaigns focused around selling a secret--
sosecret even marketing didn't know what they were working with. So they had to come up with a campaign without knowing the plots or storylines (I've done it--it's NOT easy), but it forced them to relate to the fanbase to figure out what THEY wanted. This is where the story itself comes in again--if JKR did not write the story so well to have these hooks already planted, marketing couldn't have done a thing with it. But they did, and it worked.
So, yes. Marketing and PR had a huge handle on making each book sold more than the previous one. They had a huge impact on making sure everyone was talking about Harry Potter. But the structure of Rowling's story is also a huge factor that allowed the PR teams to work creatively, and obviously interested the fans. Rowling did a lot more than just write the story, this is true. But there were also tons of people involved, including those at Scholastic (press and marketing), her personal publicist and people at her agency. Not to mention those doing press and marketing for the films that were released in between.
These are really just the basics. There's a heck of a lot more to it even still, but if I write anymore I'm going to be posting my entire paper.
