Hi,
To show how I might be your best best, I edited the first para of your sample. Here goes:
Writing a blog post, like all other writing, is a skill (a better word is craft. Craft can be improved upon).
(The opening line says writing is a skill. The next line starts talking about keeping the reader interested. It would have been better to connect the key word skill – or craft – with the reader, as in:

Jane cared and worried about the proposal. INCORRECT
Jane cared for and worried about the proposal CORRECT)
....in order to improve your ranking in Google (This can be shortened: To improve your Google rankings), you should definitely try to maximize your writing skills! (Technically, you can only maximize things that have a numbers. Use "you can optimize your..."
Just wondering: how will you decide who's the best for the project?
Thank you for your time
