Sometimes I can get the page title and sometimes I can't

I am using the “JavaScript Tracking Client” API.
The page title is obtained from the response parameter “pageTitle”.
Even when tracking the same URL, “pageTitle” may or may not be included in the response parameter.

Question 1: What is the reason why the response parameter “pageTitle” cannot be obtained?
Question 2: If there are multiple causes, please let me know each one.
Question 3: Also, is it possible that the response parameter “pageTitle” cannot be obtained depending on the browser or communication environment of the person accessing the URL?
Question 4: What measures can be taken to ensure that the response parameter “pageTitle” can always be obtained?

Hi @hmk-fukushi-taiga

Can you exaclty describe the code you use to track the page title? (The Matomo API uses the page <title> to get the page title)

Are you also sure the page <title> is set before the track?

Question 1: The reason why the response parameter “pageTitle” cannot be obtained may vary. It could be due to server-side configurations, JavaScript errors, or inconsistencies in how the page title is set or retrieved.

Question 2: Multiple causes could include server-side caching mechanisms preventing the retrieval of updated page titles, JavaScript errors interrupting the tracking process, or the page title not being properly set or transmitted by the server.

Question 3: Yes, it’s possible that the response parameter “pageTitle” cannot be obtained depending on the browser’s security settings, JavaScript execution errors, or issues with network connectivity that prevent the tracking client from receiving the necessary data.

Question 4: To ensure that the response parameter “pageTitle” can always be obtained, consider implementing robust error handling mechanisms in your JavaScript tracking client to gracefully handle situations where the page title is not available. Additionally, work closely with your server-side team to ensure that page titles are consistently set and transmitted to the client-side tracking script. Conduct thorough testing across different browsers and communication environments to identify and address any potential issues proactively.
