Keep in mind; starting with the letter A is not mandatory for higher placements in listings online. For instance, starting with the letter D is good, C is better, B is great, but A is the best.

It may help you get ahead in a list of titles but choosing a title for your blog, your book or anything else is not really in your best interests. Think about it. What kind of quality information is going to be in a book where the marketing is more important than the book/ information itself.
Even in a blog or book about marketing I don’t think a title based on being first in a list or using keywords is a smart choice. To me it shows a lack of real integrity and gives the impression of insincerity and artificialness. I would not want to put my time into writing something I had put my heart into only to show it off as something that looks like a marketing campaign, fluff.
