How do I promote my book?

Dear Readers,
I apologize in advance if this question has been asked or answered before.
If not, perhaps you all can help and guide me in this matter.
I am looking for ways to promote and create a buzz around my just-published book. While it is traditionally-published, I am told that the publisher do the bulk of marketing and other promotional activities.
However, I wish to do my share to bring greater visibility of my book to a large number of potential readers.
Below are some of the steps that I've taken so far:
1. Created a Facebook page.
2. Created a goodreads author's account and occasionally post blogs.
3. Used LinkedIn and social media (Twitter etc.) to create buzz.
4. Created and sent press release about the book's launch.
5. Leveraged my professional and personal network
6. Offered discount coupons and reading samples of the book.
7. Working with editors of websites with whom I had worked previously to get or update author's byline with a mention of book.
8. Asking for honest and critical reviews from readers who just bought my book.
9. Writing greater number of articles, quick tips, columns or creating videos to indirectly highlight the author's byline.
10. Creating Webinars/Podcasts for top websites.

Are the above ten activities enough? Have I missed out or overlooked anything important or potentially effective to my book promotion?

I'd love to have your feedback and guidance on this.

Thank you very much, in advance.

Ohh, by the way, here's my book!!
