I've written a New Blog Post on my website - It's rather long for the Goodreads format so please have a look here: https://www.dgrahamwrites.com/online-...

It dives into the deep-end of Self Promotion for Self-Published Authors and takes a hard look at the current top options available. Including Social Media Ads as well as Big-Name websites that offer pay-for-placement options.

Hope this finds more authors who are looking for advice!
