What a good writer need to keep in mind when writing RELIABLE and TRANSPARENT online articles, reviews and company analysis?

First and foremost it's important to stay as neutral as possible, as taking any sides will make the article automatically irrelevant, as what is the point in reading a biased review? That's why a good reviewer needs to cover both advantages and disadvantages and stay as transparent as possible about the sources of the information, so that the reader know on what are the particular sentences based. It is as simple as you can-you have to do an analysis, cover the topic, look into the specifics and dig deep into the specifications, but you WITHOUT taking any side! Don't be partial to any variance, remember. Make a commitment to find the truth, don't try to publish anything, as the reader seeks help in deciding, not to be amazed and read everything and all the good sides. Can't simply focus mostly on consumer reviews or main website of the business, because they may be not sufficient and informative to give the entire picture. Why, what company admits the platform 's problem? Nobody. None. That is why you will prosecute them. Check the bad reviews, you need to understand and know why the clients don't like it.

A good example of an in-depth review can be this TransferWise review.

The author really digs into the topic and tries to grasp every available aspect of this service. The platform is about online transfers, so there are obviously all of the transfer fees, exchange rates, available currencies and countries described, but also there are quotes and explanations of the most common issues, negative feedback and more. That adds up to a comprehensive and full article review and company analysis. The author dives into the platform's fees, exchange rates, hidden costs, security, reliability and overall how-to-use case. This is an important approach - What are the disadvantages of the platform? The reader  needs to know the truth and with transparent information he will be able to determine the relevance of the question or specific issues and assess whether or not to take part in this project.

Also it may be a good idea to cover maybe some alternatives and potential differences between companies, as it sets a relationship point so that the reader knows against what he can at least briefly in his head compare the features. Try to look at what features are common to the market and are good quality and value indicators for most similar services. It is also better to know what to do if you have another option. Find them for readers! Find them for readers!
