How can I change the link preview text and thumbnail image for my blog articles on Webflow? Currently, the displayed text and image do not relate to the articles when shared on social media and chat boxes.

To change the link preview text and thumbnail image for your blog articles on Webflow, you can utilize Open Graph meta tags. Open Graph is a protocol that allows you to control how your content appears when shared on social media platforms and chat boxes.

Here are the steps to change the link preview text and thumbnail image:

1. Open the page settings for your blog article in the Webflow Designer.
2. Click on the "Head" tab.
3. Inside the "Head" section, you can add custom code to define Open Graph meta tags. The following are the two most important meta tags for link previews:

- `og:title`: This tag specifies the title of your article that will be displayed in the link preview. You can set it to the title of your blog post dynamically using Webflow CMS data:
```html

- `og:image`: This tag defines the thumbnail image to be displayed in the link preview. Ideally, you should provide an image URL that is relevant to the article. You can also use dynamic data from the CMS to populate the image URL:
```html

Replace `fieldName` with the appropriate field name from your CMS collection that holds the article title and `imageField` with the field that contains the image URL for each article.

4. Additionally, you can also set the `og:description` meta tag to define a custom description for your article:
```html

5. Save the changes and publish your site.

By adding these Open Graph meta tags to your blog article pages, you will have control over how your link previews appear on social media platforms and chat boxes. Each article will have a relevant title, image, and description when shared.
