Add Asset Metadata
Just as important as the SEO document settings are the asset metadata. To make sure you don't forget to store them, we recommend that you store them immediately after uploading a file. Open the desired asset and navigate to the "Custom Metadata" tab. For image files (e.g. JPEG, PNG, GIF, etc.) you should already see three predefined entries: "title", "alt" and "copyright".
The value for "title" is displayed as additional information for images if the mouse pointer remains over the image for a longer time. This is especially useful for images without captions.
The "alt" value or alternative text must be specified, since it can be read by screen readers, which are used by users with visual impairment or blindness, and also serves as a replacement for the image. It happens from time to time that an image cannot be loaded due to a server error or that users have completely deactivated images in the browser. In this case, the alternative text is displayed instead of the image.
Last but not least, you can use the "copyright" value to indicate the copyright of an image. This information will be added to both the "title" and the "alt" text.
If you want to publish PDF or Office documents (Word, Excel, Powerpoint, etc.) on your website, it is recommended to enter the metadata before uploading. You can find out how to do this under the following links:
