In this guide, you'll learn how to organize your images meaningfully, equip them with alt text and titles for search engine optimization, and understand the role of image size.
Key Insights

Step-by-Step Guide to Using the WordPress Media Library
1. Open the Media Library
To access the media library, navigate to “Media” in your WordPress dashboard. Here, you will see all the content that has already been uploaded.

2. Uploading Media
You can upload new files to the media library by clicking “Add New.” This opens an upload window where you can select the desired files from your computer. Ensure that the images or documents you want to upload are not too large to avoid long loading times.
3. Optimizing Image Size
Before uploading an image, you should optimize it. The longer side of your image should be a maximum of 2560 pixels. A high file size can cause the website to load slowly, which can be particularly frustrating for users with mobile data.

4. Setting Image Details
After the image is uploaded, you can add a title and a description. For example, the title could be “Blueberries” and the description “Blueberries in a blue bowl.” This information not only helps your SEO but also the accessibility of your website.

5. Adding Alt Text
Alt text is a significant feature for search engine optimization. It describes what is visible in the image and ensures that search engines can better understand your content. You might enter "Team member photo" in the alt text to clarify the purpose of the image.
6. Setting Metadata for Image Usage
In addition to title and alt text, you can also specify other metadata. This information is especially helpful when the image serves a specific purpose, such as “team member photo.” This assignment is important to improve user experience and help search engines understand the content better.
7. Check Data Structuring
Once you've entered all relevant information, you can check the structure of your upload. This includes the source code of the image that is visible to search engines. Here, all configurations important for the visibility of the image are listed.

8. Insert Image into Post or Page
Once the image is configured, you can insert it into your post or page. The alt text is also considered for readers and search engines, contributing to better visibility and user experience.
