Try out the product. In order to write a review, you need to try the product. Try it out, take your time, and get to know the product or service adequately enough to be able to speak authoritatively about it.

Take notes. Gather details that you’ll need to write your review. For example, if you’re reviewing a restaurant, get the names and ingredients of certain dishes you’re trying.

Take photos.. Document your experience by taking pictures so that your readers will know what you mean.

Find out the audience.. If you are planning to submit your review to a particular website, blog or magazine, make sure you find out any specifications for the review. For example, there might be a word limit or a specific format.

Figure out your angle.. Every review has a particular perspective. You are, after all, making an argument in your review. Determine how you want to talk about the product or service. Will this be a positive or negative review? What will you focus on?

Know your audience.. Think about who will read your review. If you are writing for a more general audience, assume that some readers will need more explanation about certain references or terms you use.

Describe the service / products.. In a couple of sentences or less, describe the product that you’re reviewing. Just a brief overview in 1-2 sentences will suffice.

Write with detail. .Give lots of detail and evidence for the argument that you’re making. If you’re reviewing a music album, talk about the instruments or vocals on a particular track. If you’re reviewing a movie, talk about why the cinematography is groundbreaking and give examples from the film.

Use complete sentences. Don’t write things like, “okay food, terrible service.” This doesn’t tell the reader anything specific and therefore doesn’t make for a helpful review. Our review will carry much more weight if you write in complete sentences.

Use (useful) descriptive words.. Skip words like “meh” and “okay.” These words are not very useful in terms of describing a product. Choose more descriptive words

Personalize your review.. Relate your review directly to your personal experience. Don’t use vague statements and generalities. People reading your review will want to know about your experience.

Keep it truthful.. Be honest in your review. Don’t stretch the truth to fit with your argument one way or another. Don’t make up stuff or exaggerate to make your point.

Give a fair review.. You may have had a terrible experience with a particular plumber, but balance your review with what the plumber did right. If a meal was excellent except for the crud in your water glass, mention the negative part. People find reviews more credible if they admit the good and the bad together.

Make your review clear.. Don’t overdo the review with over-the-top praise or criticism. Eliminate extraneous words so that your meaning is clear in the review.

Proofread your review.. Take some time to read through your review carefully, checking for proper grammar and spelling. People will discount your review if it’s full of grammatical errors that make it hard to read.

Have someone read your review.. Give your review to someone to read before you post it online or publish it. It’s a good rule of thumb to have someone else read your writing to ensure that your writing is clear and your main points are adequately supported.

Submit your review.. If you’re submitting your review to a website like Yelp or Amazon, follow their review guidelines to ensure that your review will be accepted and posted.
