What Titles Do Untitled Entries Use on Social Media?

This site has some entries without titles, so I looked into what kinds of titles are used by sites like Twitter and Facebook, where people make title-less posts.

By "title" here, I mean the HTML title tag.

On Twitter, it looks like this:

Kazuhiro Hara 𝕏 on X: "Starting #金朝ツメトギ, spending just one hour from 6 a.m. on Friday morning for the future. Today I will work on maintenance related to よりひろいフロントエンド https://t.co/n2IfP38gIw" / X

So the structure seems to be:

Author name on service name: "content" / service name

The title alone gives you the whole picture.

What about Facebook?

原 一浩 - 「よりひろい... | Facebook

It is considerably simpler than Twitter.

Author name - "content... / service name

That is the structure.

By the way, what kind of guidelines does Google provide? I took a look at this page.

• Influencing your title links in search results | Google Search Central | Documentation | Google for Developers

Apparently, Google does not necessarily use the title exactly as set on the site, and instead seems to determine it automatically using some algorithm or data.

So, applying a format to this site based on the history so far, and omitting the author name because it is self-evident, I think the following would be good:

Beginning of the content + service name
