10 Common Mistakes New Book Reviewers Make on a Blog (and How to Fix Them)
You have finished a book, you have opinions, and you want somewhere to put them. That is a good enough reason to start a book blog. But a review written only for the person writing it leaves everyone else none the wiser, and most new reviewers make the same handful of mistakes in their first few posts.
None of them are fatal. They are habits, and habits can be changed. Here are the ten that turn up most often, and how to fix each one.
Retelling the plot instead of reviewing it
Assume your reader can find the blurb themselves. Two or three sentences of setup — who the characters are, where they are, what sets the story in motion — is usually plenty. After that, the review should be about the book, not a summary of it.
A quick test: read back a paragraph at random. If you could delete it and the reader would still know whether you recommend the book, it was plot, not criticism. The verdict should arrive early, too. Putting "I absolutely loved this" at the end of 700 words of summary means most people will never reach it.
Two hundred words of setup followed by "I really enjoyed this one, definitely worth a read" is a summary with an opinion stapled to the end.
One useful structure is to spend one paragraph on setup, one on what the book is trying to do, two or three on how well it does it, and one on who should read it. That keeps the plot in its place and gives your actual opinion room to breathe.
Spoilers with no warning
Twists are the usual casualty. Writers who would never reveal a plot point on purpose will still mention a death, a betrayal or a late reveal while "discussing the themes". If a reader learns the ending from your review, they will remember that, not your analysis.
Decide before you write what counts as a spoiler. A workable line: anything from about a third of the way in, any death, any reveal about who a character really is, and any romance that shapes the ending. Then choose one approach and stick to it.
A simple spoiler system
- Keep the main review free of anything that happens in the back half of the book.
- Add a clear line — Spoilers below — in bold, not a hint buried mid-sentence.
- Put spoiler discussion in one block at the very end, after the verdict, so people can stop reading.
- Keep spoilers out of your headings, your opening line and your social posts.
Some reviewers write two posts: a spoiler-free review and a longer discussion for people who have finished the book. More work, but it serves both audiences properly.
It also helps to ask a friend who has not read the book to scan your draft. They will catch the moment you casually mention that a character "was never really on the protagonist's side", which is exactly the kind of line you stop noticing after you know the ending.
Praise that says nothing
"The characters were so relatable." "The writing was beautiful." "I couldn't put it down." These sentences appear in thousands of reviews and tell a reader almost nothing. The fix is to name the effect, then show the mechanism.
Instead of "beautiful writing", say what the sentences actually do: short, clipped dialogue that makes the arguments between the two leads feel like real arguments. Instead of "relatable", describe one specific thing a character does — the way she rereads a message before deciding not to reply — and let the reader draw the conclusion. If a sentence could be pasted into a review of a different book without changing a word, it is filler.
It also helps to say what did not work. A review that praises everything reads like an advert, and adverts are easy to ignore. If a book dragged in the middle, say where and why. If a subplot fizzled, name it. Criticism is not the same as hostility; a thoughtful negative point shows you were paying attention, and it makes your praise more credible when it comes.
Try this formula for any point you want to make: claim, evidence, effect. The claim is "the pacing falters". The evidence is "the middle hundred pages repeat the same argument". The effect is "I started skimming, which is the last thing you want in a thriller". That is a review. "The pacing was bad" is just a mood.
Writing for yourself instead of a reader
A diary entry records what you felt. A review helps someone else decide whether to spend money and time. Those are different jobs. New reviewers often open with "I picked this up because I was in the mood for something cosy", then spend four paragraphs on their reading week. The reader is happy for you, but they still do not know if the book is any good.
Ask who you are writing for before you start. A general reader who likes the genre? A friend who trusts your taste? A librarian looking for quiet YA romance with no explicit content? Once you know, you can cut anything that only matters to you. Keep the personal details that illustrate a point — "I read this in two sittings on a rainy weekend, which tells you how propulsive it is" — and lose the rest.
Failing to say who the book is for
"I loved it" is not a recommendation unless the reader knows whether their tastes match yours. Make the audience explicit. Is this for readers who already love slow-burn literary fantasy? For people who want a fast plot and do not mind thin characters? For fans of a specific author, trope or subgenre?
A simple sentence near the verdict does more work than another paragraph of analysis: If you like haunted-house stories where the horror is grief rather than gore, this will land. If you want jump scares on every page, it will not. That tells a reader more than a five-star rating ever could.
You can also mention comparable titles, but use them carefully. "For fans of Rebecca" sets an expectation. If the book is a light contemporary romance with a creepy mansion, say that instead. False comparisons create disappointed readers and angry authors.
Star ratings that fight the review
Ratings are useful, but they have to match the words. A four-star rating followed by "the plot was predictable, the romance had no chemistry, and the ending was rushed" confuses everyone. Either the rating is too high or the review is too harsh. Readers notice, and they stop trusting your stars.
Decide what your stars mean and write it down somewhere on your blog. A five-star book does not have to be perfect; it has to be a book you would press into a friend's hands. A one-star book does not have to be objectively terrible; it has to be one you would actively warn people away from. Once your scale is clear, your ratings become information instead of mood.
Also beware of rating everything five stars because you only review books you picked for yourself
