Working with book influencers and reviewers
A book influencer is a reader with an audience. Not a journalist, not a critic, not a channel you can buy: a person who reads for pleasure, posts about what they read, and has collected followers who trust their taste.
That trust is the entire asset, and it is fragile. A recommendation from them carries weight precisely because it was not bought. The moment their audience suspects a post is advertising, the post stops working — for them first, and for you immediately after. Every rule below follows from that one fact.
It also means your side of this is slower than most marketing. You are asking a stranger to spend several evenings on your book and then say something honest about it in public. No volume approach survives contact with that sentence.
Finding the right ones
Search your genre, not "book reviewer." Searching for reviewers returns the accounts that everyone else found first, which are the ones with the longest queues and the lowest acceptance rate. Searching for the thing you wrote — the subgenre, the trope, the period, the specific kind of book — returns people whose whole feed is your audience.
Look for people posting about books like yours. Not books in your broad category. Books a reader would shelve beside yours. If you cannot name three, that is a sign to work out your comparison titles before you work out your pitch.
Read the comments, not the follower count. An account with 2,000 followers where people argue about endings in the replies is worth more than one with 80,000 where nobody says anything. Arguments mean the audience is present and reading. Engagement beats reach here every time, because the mechanism is a personal recommendation rather than an impression.
Check they are still active. Plenty of accounts stopped posting a year ago and still look alive at a glance. Look at the date on the most recent post before you write anything.
The approach
Read their content first. Enough to know what they like and what they refuse. This is not a courtesy, it is how you find out whether to ask at all.
Follow their stated preferences. Most reviewers have a review policy somewhere: a pinned post, a page linked from the profile, a line in the bio. It says what they accept, what they never accept, which formats they want, and how to contact them. Ignoring it is the fastest way to be ignored back, and reasonably so.
Write one message to one person. Name why your book suits them specifically — the book of theirs it sits beside, the thing they said they wanted more of. Two sentences of that beats any amount of polish.
Keep it short. What the book is, who it is for, one comparison, the formats you can send, and an offer to send one. Not the synopsis, not the full blurb, not your biography.
Offer the format they prefer. EPUB for most, a print copy for anyone who photographs books, a PDF only if they asked. Sending something they cannot open produces silence, not a review.
Accept silence as an answer. No reply is a no. Chasing it converts a neutral non-answer into a bad impression, and these people talk to each other.

What never to do
Never argue with a review. Not in the comments, not in a message, not in a subtweet a week later. An author arguing with a reviewer is content — it gets screenshotted, it spreads far beyond the original post, and it outlives the book. The review that annoyed you would have been read by four hundred people. Your reply will be read by forty thousand.
Never send an unsolicited file. An attachment to a stranger is not an offer, it is an imposition, and it lands in spam filters besides.
Never send the same message to fifty people. They can tell. They compare. A pitch that names nothing specific about the recipient reads as a mail merge, because it is one.
Never ask for a rating. Ask for an honest opinion, or ask for nothing. A request for stars conditions the response and voids it.
If money is involved
Paid arrangements do exist — sponsored posts, paid placements, services of various kinds. Disclosure requirements vary by country and by platform, and they sit on the reviewer as much as on you. Separately, retailers have their own policies about compensated reviews, which differ from store to store and change. Check the rules that apply to your arrangement, and if real money is involved, check them with someone qualified rather than with an author forum.
The practical version: if you pay for anything, pay for the honest post, never for the verdict, and make sure the arrangement is stated openly. An undisclosed paid review is worth less than no review, because when it surfaces it retroactively taints every genuine one you have.
The cover is doing most of the work
These platforms are visual. A book gets picked up, held up to a camera, set on a blanket next to a coffee, and shown at the size of a thumbnail on a phone. Which books get treated that way is decided largely by whether they look good in that frame.
That is not a promotion decision. It is a design decision you made months earlier, and it is the one part of this you fully control. See The thumbnail test.
Make your cover
The Cover Maker is free to use: name your book, bring your artwork, and it draws the full wrap — front, spine and back — to your printer's own measurements. You only pay when you want the files without the preview watermark.
