Is there a way to update the image names on my Webflow website for SEO optimization, even if they have already been uploaded without renaming them? Are there any plugins available to help with this task?

Yes, you can update the image file names on your Webflow website for SEO optimization, even if they have already been uploaded without renaming them. However, it's important to note that changing the file names might result in broken links if the images are referenced in the website's code.

To update the image names in Webflow, follow these steps:

1. Open your Webflow project and navigate to the page where the image is located.
2. Select the image element and click on the "Settings" tab in the right sidebar.
3. Under the "Image" section, you'll find the "Alt" field. This is the text that describes the image for accessibility purposes and search engines. Modify the alt text to incorporate your desired keywords or a descriptive explanation of the image.
4. Next, you will need to replace the actual image file with a new one that has the desired file name. To do this, click on the image element again, and in the Settings tab, click on the "Replace" button. Choose the new image file from your computer and upload it.
5. After replacing the image, make sure to check that it still looks good on your website.

Regarding plugins, as of my knowledge, Webflow does not have a direct plugin that automatically renames image files for SEO purposes. However, you might be able to find third-party tools or applications that can help you bulk rename files. Just make sure to test and backup your website before making any major changes.

Remember, SEO optimization goes beyond just image file names. It's crucial to focus on other aspects such as optimizing page titles, meta descriptions, headings, and relevant content to boost your website's search engine visibility.
