Open graph can resolve relative url?
Directly put, Open Graph (OG) tags require absolute URLs. Relative URLs are not reliably interpreted across all platforms. To ensure content is correctly parsed and displayed on social media, always specify the full URL:
In the ASP.NET MVC3 context, you can make use of the inbuilt Url.Content method to convert relative URLs to absolute ones.
Understanding URL formats: absolute vs. relative
To navigate the web, it's important to grasp the difference between the two main URL types:
-
Absolute URLs are entire web addresses, comprising the scheme (
http://orhttps://), and they're all you need to access online resources. In the great wide world of the web, they're the surefire way to get your content discovered by the Open Graph protocol. -
Relative URLs depend on the current context for interpretation, and while they simplify intra-site navigation, they're not designed to communicate effectively with external platforms that rely on absolutes, like OG.
Facebook & the Open Graph protocol: A tale of strict adherence
The creators of the Open Graph protocol engineered it to be precise about URLs. As far back as 2012, Facebook officially addressed relative URLs as a non-starter in the Open Graph context by closing the issue in their bug tracker. Their verdict: OG mandates absolute URLs, including HTTP/HTTPS schemes.
Converting URLs in ASP.NET MVC3
Albeit ASP.NET MVC3 doesn't directly feature an option for this URL transformation, you can still enter the ring. With a handy custom extension method, you can convert relative URLs to absolute ones.
Open Graph's "Gotchas"
Here are some common pitfalls to avoid when dealing with OG:
- Expecting Open Graph to resolve relative URLs based on the page's current context will lead to sharing woes.
- Neglecting Facebook's scraper requirements can result in incorrectly displayed media. Always use absolute URLs.
- Ignoring inadequacies of relative URLs can negatively impact Twitter Cards and LinkedIn posts, depriving them of clickable visuals that promote user interactions.
Bracing for URL transformation
Here's your action plan for effectively handling URL issues:
- Develop a helper method that converts relative URLs to absolute URLs. This will be your secret sauce for reliable URL transformations.
- Regularly use social media debuggers and validators as your virtual test lab to ensure the smooth resolution of URLs.
- Maintain good documentation for your URL handling method. An informed team will bring about consistency and sensibility to your development process.
