Meta Link is a way of accessing and generating images on demand without using any fancy tools. You only need to edit your HTML code. Adjust your og:image and twitter:image meta links in <head/> and you are good to go.

Automatic blog post generation for social media

How to use?

Go to 'Domains' section in your account and add domain of your blog or website.

If your blog uses subdomain (subdomain.domain.com) then you need to use it WITH the subdomain. Wildcards like '*' are not supported.

Create a meta link according to the following format:




  • TEMPLATE - your template identifier,
  • BLOG_POST_URL - link to your blog post

You can use this link in open graph tags in order to generate image when your blog article is posted on a social media platform like Facebook, Twitter or other.

Adjust meta tags

Add or modify your <meta/> tags in <head/> your blog HTML code.

    content="summary_large_image" />  
    <!-- other meta tags -->

Bannerly will take your page title, description and image and put it into corresponding components.

Correct component naming is very important. Otherwise, Bannerly won't know into which component changes should be applied.
