YouTube video embeds are a very easy way to add event videos to your webpage. However, in their native embed format, they can significantly slow down the page due to excessive scripts and third-party tracking.

With a few simple tweaks you can reduce the resources these embeds take and increase your webpage's speed.

Why Optimise YouTube Embeds?

Embedding a YouTube video on your webpage can slow down page load times due to excessive external scripts and tracking elements.

The best way to optimise this is by using YouTube’s No-Cookie Embed Code, which reduces third-party requests and improves page speed.

Guide to Optimising YouTube Embeds

Step 1: Find the YouTube Video ID

Every YouTube video has a unique VIDEO ID , which can be found in its URL, see:

Instead of using the standard YouTube embed code, use the No-Cookie Embed Code to reduce third-party tracking and improve page speed, use the following code remembering to insert your VIDEO ID in the new code (see bold below):

<iframe width="560" height="315" loading="lazy" src="https://www.youtube-nocookie.com/embed/VIDEO_ID?rel=0" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen> </iframe>

• loading="lazy" prevents videos from loading until needed (important).

• ?rel=0 – prevents YouTube from showing related videos from other channels when the video ends, keeping users focused on your content.

Step 3: Add the Code to Your Webpage

If you are using ShowOff, follow these steps:

• Go to your page in ShowOff where you want the video to appear.

• Add a widget by selecting the appropriate section.

• Choose '3rd Party Code' as the widget type.

• Paste the No-Cookie Embed Code (from Step 2) into the code editor.

Why YouTube Embeds Impact Page Speed

The standard YouTube embed loads multiple external requests, including:

• YouTube Player Scripts (e.g., player.js, embed.js).

• Google Tracking and Ads Scripts (e.g., Google Tag Manager, DoubleClick Ads).

• Engagement & Tracking Features (e.g., play tracking, recommendations, user session tracking).
