# Metadata

## In this article, we’ll explain how to customise the social metadata shown beneath shared images and links, and how to add optional alt text to your images to improve clarity and accessibility.

### **Metadata**

To customise your metadata text:

1. Click on the **Metadata** tab
2. In the **Title **box, add the main message that you would like the stakeholders to have, e.g. *I'm speaking at Event Title - join me!* - For your speakers, the title is limited to 65 characters, so it is a good practice to keep it short
3. In the **Description** box, add the action that you would like your stakeholder's audience to choose, e.g. *Register now, Sign up now; *the description character limit is 155

Please note that the preview displayed on the right side is for illustrative purposes only. If you select a LinkedIn curated share, the metadata will not be shown.

We understand that sometimes social media platforms may not accurately display the metadata when a post is initially shared. This can be influenced by factors such as the internet connection at the time of sharing and the specific social media platform being used. Unfortunately, there is no way to modify this behaviour within Gleanin to ensure it always works perfectly.

### **Alt text**

Alternative text, or alt text, provides a concise description of images and visual elements on a webpage. Its main purpose is to aid individuals with visual impairments by conveying the meaning and context of these visuals. Screen readers like JAWS, NVDA, and Microsoft Narrator read this information aloud, helping users understand the content being presented.

To add the alt text:

1. Click on the **Metadata** tab
2. In the **Alt text** box, add the alt text that you want to use.

When crafting alt text, it's crucial to clearly and succinctly communicate both the content and purpose of the image. Ideally, alt text should be one or two sentences long, focusing on key details that enhance the user's comprehension. Avoid repeating nearby text or using phrases like "a graphic of" or "an image of," as these do not add value.

It's important to recognise that poor alt text can lead to confusion rather than clarity. For example, "A full buffet with cold meats and vegetables" fails to convey useful information, while "Our pricing is all you can eat" effectively communicates the intended message of the image. It's preferable to leave alt text blank than to provide misleading or irrelevant descriptions.

In essence:

1\. Be clear and concise: Accurately depict the image without making assumptions about its meaning.

2\. Provide relevant context: Describe how the image connects to the overall content of the page.

3\. Include descriptive details: Mention aspects such as skin tone, hair colour, and hairstyle to enhance understanding.

4\. Keep it brief: Aim for a length of 100 to 250 characters for optimal clarity and effectiveness.
