Container IDs
Viafoura uses Container IDs in order to logically organize content. Container IDs are used to tie the engagement tools to your content.
Typically your CMS, or database will have a persistent unique identifier associated with each piece of content or article you publish. This can directly be used as the Container ID.
Container IDs can be assigned server side, or client side as long as values are set before the Viafoura JavaScript code initializes.
Container IDs must be between 1 and 200 characters long
Container IDs must be between 1 and 200 characters long. Because of this, we do not recommend using the article URL as container ID, even if its permanent and won't change in the future, since the URL might be longer than 200 characters.
A Container ID can be assigned to multiple engagement tool. For example, you can create a container ID such as unique-article-about-politics and use it to create any of our widgets (live stories, conversations or community chat).
The Container ID can be defined at two levels:
- Article level
- Widget level
Article level container ID
You can define your Container ID in the <head> of the article:
<!DOCTYPE html>
<html>
<head>
<meta name="vf:container_id" content="unique-article-id" />
</head>
...
</html>
This has the advantage that the Container ID you set in the head of the page
will be used for all widgets that are loaded on that page.
Widget level Container ID
You can also set a Container ID directly in the widget embed code. Below is an example of that for the Conversations product.
<vf-conversations vf-container-id="unique-container-id"></vf-conversations>
This has the advantage of being able to include multiple containers on a single page that load different content. For example a page with live chats on different topics.
This method of Container ID assignment takes precedence over the page level assignment.
Meta tags
Viafoura tracks a set of meta tags for variety of functional and analytics purposes.
These are listed below:
Meta Tag | Description |
|---|---|
vf:container_id | Required: can be overwriten at widget level with the vf-container-id parameter. Used to tie the engagement widgets to your content. |
vf:url | Optional: falls back to og:url Used to generate links back to the page from our tools and will serve as the canonical URL for the page. |
vf:image | Optional: falls back to og:image This link is used to associate an image with the article. The image will be used across our products, namely, Trending Conversations - Carousel, browser push notifications and notifications in the feed. We recommend using images that are 210 pixels by 140 pixels for optimal performance. |
vf:image:alt | Optional: falls back to og:image:alt Used to provide an alternative textual image description for users with vision impairments. We recommend to provide alt text if you also provide an image. |
og:url | Optional: falls back to page URL Used to generate links back to the page from our tools and will serve as the canonical URL for the page. |
og:title | Optional: falls back to page title tag Used to designate the page title which we will display to users when referencing the page. |
og:image | Used to determine the image thumbnail to display when referencing the page. It should be a fully qualified URL of the image you want to associate with the page. We recommend that this image be served over HTTPS. |
og:image:alt | Used to provide an alternative textual image description for users with vision impairments. We recommend to provide alt text if you also provide an image. |
