How to Research a Product Before Buying Online

When researching a certain product before buying it at an online shop, it is necessary to understand what one wants, study the official characteristics of the product, compare it with similar products, consider the feedback left by previous buyers, check whether the seller is reliable, and calculate the total cost, shipping terms, and return conditions.


For instance, let’s say you purchase a laptop from the Internet. You see the beautiful pricing, images, descriptions, and reviews of the product. However, you neglect to look at the technical aspects, credibility of the seller, and return policy of the product.

That is precisely why learning how to research a product before buying online is important. It can help you prevent yourself from buying products that are not suited for you, from deceptive information, and also from any unexpected costs. However, it appears that there are other things that one needs to consider besides the cost when shopping on the internet. One has to know what exactly one is buying, whether it will suit one, and whether the seller is reliable.

Why Is It Important to Research a Product Before Purchase?

When using the Internet to make purchases, you get an opportunity to browse through numerous items without actually visiting a store. This ease, however, has a negative side - one may not be able to examine the product before making a payment.

The picture on a product page may differ from that which will be delivered to your house. The description of a product may list all the positive aspects of it while leaving the limitations unnoticed. Finally, the low price does not guarantee that you get a good deal.

Therefore, why should you not believe everything written about the product? The purpose of advertising is selling, and research is intended for informing about a product.

By conducting research, one can:

  • Find out whether the product is compatible with your requirements.

  • Understand how the products are different from each other.

  • Be well aware of the quality of the product and its limitations.

  • Look for any fake descriptions or suspect vendors.

  • Evaluate the total cost of the product in various online stores.

  • Consider what you can do in case of problems.

Honesty be told, the best buy is not necessarily the most affordable or popular one. Plus, check out our latest guide to choosing the right travel photography lens for different travel photography needs.

How to Research a Product Before Buying Online?

Before placing an item in your shopping cart, spend a few minutes making sure the item fulfills your requirements. Check the specifications, customer reviews, credibility of the seller, and much more besides price to save yourself from regretting your purchases.

Step 1 – Requirement Identification from the Product

Before opening multiple shopping websites, take a moment to decide what you actually need. Otherwise, chances are high that you will waste time evaluating products that have features that you do not want.

First of all, think about the usage. Is the computer intended for academic or professional use or gaming? Is the washer needed to be used in an apartment or a house? This will help you to identify the appropriate features.

Fix the budget for the purchase. Identify how much money can be used to buy the item, while some part should be reserved for accessories, transportation, and servicing costs.

Divide the features into two groups:

  • Important features - The features without which the product will not satisfy your needs.

  • Unimportant features - Features which can be helpful, but not necessary.

Don't forget the basic details like size, compatibility, availability of space, energy requirement, and so on.

Step 2 – Collecting Product Details

After finding out what it is you need, collect details about it through reliable sources. A great place to start is the manufacturer’s website, which will offer you all the specifications about the particular product you wish to buy.

But this shouldn’t be your last stop.

Search for independent reviews of the product, respected tech magazines, specialized websites, and information about consumers. Reviewing multiple sources can give an indication of how true the advertised features really are based on more in-depth information.

The model number is also important. Some companies produce a number of different versions of the same product, which vary quite widely in their specifications.

For instance, two laptop computers may have virtually the same names but have differences in their specifications such as processors, RAM, memory capacity, or screen resolution. You could end up selecting a product that does not match your expectations by comparing the wrong specifications.

Editor’s Tip: Always try to download the manual for the product where possible. This may provide important information that could be missing from a brief description of the product.

Step 3 – Know about Features and Specifications of the Product

The product specification defines how well a product can work. Sometimes, technical information can seem baffling, especially when it comes to comparing products that have specifications about which one does not know much.

What one needs to understand is the specifications that influence the performance of the product in day-to-day activities. For instance, when one searches for a laptop, one may consider:

  • RAM

  • Storage

  • Processor

  • Battery capacity

  • Display

Step 4 – Compare Similar Products

When you have already made a shortlist of products, start comparing them to each other. This step is the most helpful for how to compare products online, especially in cases where several similar models exist.

However, it is not wise to compare products solely based on prices. Their specifications, accessories, warranty, and other practical characteristics should be taken into account.

Let’s see an example of how to compare three laptops:

Research factor

Laptop A

Laptop B

Laptop C

RAM

16GB

256GB SSD

512GB SSD

Illustrative numbers, not guaranteed product features and prices.

So which one would be better?

Laptop A could work well enough for daily use, but Laptop B could be a more balanced choice for multitasking purposes. Laptop C could be worth considering if you have extra storage space requirements. In such a way, you can see that make purchases. 

Step 5 – Checking Product Reviews and Ratings

Customer reviews can provide useful information regarding the qualities, functions, durability, and possible problems associated with the use of specific products. But not all ratings are reliable enough.

How to find product reviews and not be deceived?

First, do not focus only on the star ratings; a detailed review of how a certain vacuum cleaner performs on carpet is much better than simply saying that this product is amazing.

Look for:

  • Recent reviews that reflect the current product version.

  • Customer photographs showing the actual item.

  • Repeated complaints on the same topic.

  • Information on long-time usage rather than initial opinions.

  • Comments on the product features relevant for you.

However, there is one other thing you should take into account: do the reviews relate to the product you're interested in?

Sometimes, e-commerce websites compile reviews on various colors, sizes, or product modifications. A well-rated product could differ greatly from the one you're going to buy.

Beware of reviews that are too similar, full of generic compliments, or lacking information on the real experience of the customer. This doesn't mean that a review is fake, but it deserves extra consideration.

To be honest, a few reviews with some details would say more to you than dozens of five-star reviews without any explanation.

Step 6 — Check the Seller's Credibility

But even a quality product can be a disappointment when you make your purchase from a questionable source.

This becomes especially relevant if you are purchasing products via the online markets where various vendors offer the same product.

You must investigate the vendor's credentials, address, contact details, and customer support before you place an order. The vendor's longevity and independent complaints are key factors to consider.

Also consider the following:

  • Does the seller provide clear product descriptions?

  • Are delivery estimates and shipping charges displayed?

  • Is there a straightforward returns and refund policy?

  • Does the website use secure payment methods?

  • Does the seller explain warranty coverage?

  • Are there any indications of impersonation or suspiciously low prices?

Compare the cost of products purchased directly from manufacturers versus products purchased from a third-party marketplace seller. While the marketplace may act as the platform for transactions, the seller may be held accountable for completing the transaction.

EU consumers should note whether sellers in marketplaces are classified as professional traders or private individuals. This is an important point because consumers may have different levels of protection.

Step 7 – Understanding Prices, Delivery and Returns

You have located a product that meets your needs, and the reviews sound fine; the seller seems to be trustworthy as well. So, are you ready to make the payment? 

Not yet.

First, calculate the total purchase cost. The advertised price might not include delivery, additional taxes, import charges, or optional accessories.

If you're buying from an overseas retailer, check whether customs duties or other charges could apply in your country.

Next, review the delivery arrangements. Check the estimated arrival date, tracking availability, delivery location, and what happens if the parcel is delayed or damaged.

Return policies deserve equal attention. Find out:

  • How long you have to request a return.

  • Whether opened products are eligible.

  • Who pays the return shipping costs.

  • How refunds are processed.

  • Whether restocking fees or other conditions apply.

Consumer rights vary between the UK and individual European countries, so don't assume every retailer follows identical rules.

For instance, UK customers normally have 14 days after getting their online order to tell the seller about their intention to cancel it, and another 14 days to send it back. 

In the European Union, consumers have a 14-day cancellation right for goods purchased online, except for a few items that fall outside the rule. The EU regulations also provide at least two years’ legal warranty for defective and improperly described products bought from professionals.

Check your local regulations before ordering.

Some Common Errors in Product Research

Some mistakes to be aware of are as follows:

  1. Dependence on only star rating: Star rating is not always indicative of fulfilling your requirements.

  2. Ignoring specifications: Although products look the same, there may be differences in their features.

  3. Comparing mismatched models: Always take note of product details, including sizes and configurations.

  4. Believing in exceptionally low prices: Verify whether the seller and the product are legit before buying.

  5. Omitting the return policy: An affordable product may turn into an expensive one due to its difficulty to return.

  6. Overlooking other expenses: Shipping costs and subscriptions can add up to the final price.

And don’t let a countdown clock or a limited-time offer persuade you into buying a product without proper research. Browse the Shoptique website to find more guides related to online shopping.

Frequently Asked Questions (FAQ)

First, you need to find your needs and budget. Next, you need to research the specifications of the product, look at alternative products, customer feedback, the authenticity of the seller, delivery charges, and return policy.

Product websites, manuals, recognised consumer organisations, review sites, and specialised websites could provide some good information. Compare information from different sources instead of relying only on the information on one website.

You can identify specific descriptions, realistic pictures, detailed experiences, and consistent reviews from multiple platforms. Be wary of redundant information, general praise, and reviews that do not seem to be about the actual product.

Consider the specification, quality, necessary features, compatibility, warranty, user comments, shipping cost, and ultimately the price. Please ensure that you compare similar models or versions.

You can check the online seller's trustworthiness by checking their contact details, customer reviews, payment terms, delivery process, and return policies. In case of purchases made through online marketplaces, ensure you do a background check of the individual seller and not just the online portal.

Specifications will make you realise how well the product fits your needs. They will also show the difference between different models of products so that you won’t waste money on useless options.
