It would be beneficial to have a different title tag than your heading tag when the heading is too lengthy and risks being truncated in search engine results.
- When your heading doesn’t accurately describe the contents of the page
- When your heading is too long and will get cut off in search engine results
- When your title is more interesting than your heading
- Never, the two elements should always be the same
The correct answer is: When your heading is too long and will get cut off in search engine results
Explanation: There are occasions when having a distinct title tag from your heading tag is advantageous. A prime example is when the page heading is extensive. In such cases, crafting a concise version for the title tag is beneficial. This is due to the fact that Google typically truncates titles exceeding approximately 60 characters. Therefore, to ensure your title is fully visible in search results, it’s wise to keep it short and relevant, even if it differs from the page’s main heading.
