Finding the best new TV or washing machine can be a daunting prospect! In order to make sure you get the best deal, you need to:
- Understand the technical jargon and which features are actually important
- Compare different products to find the best spread of features you want
- Read reviews to see whether other customers liked the product
- Consider each product's running costs & age
- Compare prices, availability, shipping cost, etc.
It's not always as simple as just going with the 5-Starred Amazon product: A product with great reviews is no good if you can’t actually buy it at a sensible price. Likewise a product with an amazing spec is no good if the reviews are terrible.
At Kagoo our mission is to make it easy for you to find the best products and that’s why we developed the Kagoo Score - an easy to understand score that impartially measures how good each product is.

What Data is the Kagoo Score Based On?
We start off by searching the web for as much data as we can find on every electrical product on the market - this is a process known as 'crawling'. As you can imagine, that's a lot of data! We crawl millions of pieces of product data daily, and store several billion individual pieces of product data in our database.
For example, let's imagine you were looking for a new television, and we crafted a new score just for you. The data we would crawl for this TV may include:
- The TV's name and any alternate titles, model numbers and manufacturer’s descriptions
- Images, both by itself and placed in a room
- Technical specs and feature lists
- Energy consumption data for the TV, assuming average watching habits
- Expert reviews and awards from thousands of expert websites
- User reviews
- Video reviews
- Prices and price history for the TV
- Popularity compared to other TVs and Amazon Salesrank
- Any applicable vouchers or promotions
All this data goes through a validation process to ensure that no erroneous or strange info sneaks in - which helps guarantee our product comparisons are always based on credible information. From this we gain a very broad picture of every facet of the TV - which is then analysed and calculated as a Kagoo Score!
How is the Kagoo Score Calculated?
The Kagoo Score uses 6 separate sub-scores, each covering an important area of your TV:
- Reviews Score - Based on the user and expert reviews. More weighting is given to authoritative expert review sources.
- Features Score - We look at all the important features and compare those features to other TVs currently on the market. The better the feature set, the higher it will score. Further explanation of how we calculate this important metric is provided at the bottom of this article.
- Value for Money Score - We find the best prices on the market for the TV, and then compare those prices to the feature set and specification. A TV with lots of features at a low price will receive a high Value for Money score.
- Age Score - We look at how long the TV has been on the market. A recently released product will score more highly than an older one.
- Popularity Score - We crawl sales data and best seller stats to determine if the TV is currently popular amongst consumers. 'Popularity' indicates that the market considers the product to be a good purchase. The more popular it is, the higher the popularity score.
- Running Costs Score - For applicable categories (i.e TVs, washing machines or fridges) we look at the water and electricity consumption figures and benchmark this against competing products. The lower the energy usage, the higher the running cost score will be.
Each of the above scores is then combined into an overall Kagoo Score. The 'weighting' (how important each category is to the final score) varies by category: so for TVs the weighting applied is as follows:
You can then look at the final Kagoo Score for your TV, and it should hopefully provide a concise evaluation of whether the TV is worth buying or not. Helpful stuff!
Is the Kagoo Score Impartial?
Unlike some other comparison sites, the Kagoo Score is completely impartial. In fact the process is fully automated and there is no human influence on determining which products rank the highest.
There is also no influence from brands or retailers on which products get ranked at the top of our lists. This makes the Kagoo Score a trusted, objective measure of how good each product is.

How Often is Kagoo Score Updated?
The Kagoo Score for each product will change over time. This is deliberate, since over time new products come to market which may be superior to existing products causing the score of the older products to be reduced. Also products will receive more reviews over time and as people start to use the product more the review score may change.
To keep up to date with these changes we update the Kagoo Scores for all our products every week.

How Do You Calculate Your Feature Scores?
The feature scores are an important part of how we rank of products and we have gone to great lengths to create a feature ranking system which is impartial and fair.
Firstly we identify all of the technical attributes for each product. This is often hundreds individual data points for each product, ranging from how big the screen is, to how long the power cord is.
We then rank the attributes according to importance, so for example on TVs the screen size, screen resolution and whether it features OLED technology would be amongst our most important ranking attributes.
Then we take all the data points for each attribute across every product currently on sale in the market. For example we take all the TV screen sizes currently on the market. We normalise this data, removing any spurious items or outliers to create a value distribution for each attribute.
Finally we are then able to rank each product on each attribute by benchmarking its attribute value against the value distribution for all products. For example we can determine how good a 40" TV screen size is considered in the current market place.
We repeat this process for every attribute and the combine the attribute scores to create an overall feature score for each product.
