KDP Book ebook ads optimization and reviews gathering

I have posted 2 books on Amazon: one e-book and another accompanying journal. Both on the same topic. I have set up the ads on ad console for the ebook. However, it needs to be optimized by further key word analysis etc. https://www.amazon.com/Nurturing-Emotional-Intelligence-Prophetic-Personal-ebook/dp/B0DMW9Z4FK

Also looking for help in managing reviews. Need to come with a strategy to reach out to relevant groups in social media (fb, discord, etc.,) and other channels to get reviews for the book on Amazon. Somebody with previous experience and results in this is prefferred, especially with a Muslim audience as target audience are Muslims.
