Question 1

What is spark.app's Open Graph type?

Accepted Answer

spark.app declares `og:type` as `website`. This tells Slack how to categorize the content when generating a preview.

Question 2

Does spark.app declare image dimensions?

Accepted Answer

spark.app sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.

Question 3

What headline does spark.app use for social previews?

Accepted Answer

spark.app's social headline is "Spark.app - Ignite Your Productivity" (36 characters).

Question 4

What description does spark.app use for social previews?

Accepted Answer

spark.app's social description reads: "Spark - The productivity app that helps you get things done" (59 characters).

Question 5

What's the biggest issue with spark.app's Slack preview?

Accepted Answer

og:image uses a relative URL. Social platforms cannot resolve relative URLs. The image must be an absolute URL starting with https://.

Question 6

How can I improve spark.app's social previews?

Accepted Answer

Review the recommendations above - they list specific issues and provide ready-to-paste meta tag snippets. The highest-impact fixes are usually a properly sized `og:image` (800×418), a clear `og:title` under 60 characters, and a 50-155 character `og:description`.
