Feefo are a company that provide customer reviews. It helps all sorts of people from the other customers, to buinesses owners to make sure they are doing things right.
It's nice and simple solution that integrates well but it comes at a bit of a cost, esepcially if you have the Media Panel visible.
The Media Panel snippet loads up all 17 images into a grid. Each grid square is 63px but the images loaded are much larger at 800px. So it's a lot of extra weight to your site (1.6 MB in total). It's great that they lazy load the snippet so it only shows when the user arrives at the locations. But it's expensive and I question the value of show them at all.
To give you an idea of this expensive snippet:
And the carbon emissions produced per load would be:
It really starts adding up doesn't it!
Simply uncheck the "Show Media Panel" checkbox on the Feefo admin dashboard, wait a bit, then you're done. It will display the reviews in a list only removing the uneeded farts and media gallery from your website.
Here's come calculation on how I got to some of these numbers, I've used the WebsiteCarbon API to calulate the bytes to CO2 so that's how I got to the 0.95 figure for 1.6mb of images.
const SIZE_TO_CO2_GRAMS = 0.95;const MONTHLY_VIEWS = 10000;const GRAMS_PER_FART = 0.02; //const GRAMS_PER_OAT_LATTE = 389.6;let gramsPerYear = SIZE_TO_CO2_GRAMS * MONTHLY_VIEWS * 12; // 114,000g of CO2let fartsPerYear = gramsPerYear / GRAMS_PER_FART; // 5,700,000 farts per yearlet oatLattesPerYear = gramsPerYear / GRAMS_PER_OAT_LATTE; // 292.6 oat lattes per year
