Google’s search results are showing a title for one of my pages that differs from the title tag I set. The displayed wording is taken from text elsewhere on the page, and it’s not obviously inaccurate, but it makes the result less clear than the title I wrote.
What signals might lead Google to choose different wording, and how can I tell whether the change is specific to one search or happening consistently? I’m trying to understand Google title link rewrites before making edits that might not address the cause.
