I recently started optimizing my website for SEO and I want to make sure that Google Search Console and Google Analytics weren’t already set up by someone else before.

Is there any reliable way to check if these tools were previously connected to my website (for example by a previous developer or SEO manager)?

I’ve already tried:

• Checking for tracking codes (UA-, G-, gtag.js) in the website’s HTML.

• Searching inside Google Tag Manager (if any).

• Verifying ownership in my Google account.

But I still can’t confirm if someone else already had ownership earlier.
Is there any technical method, API, or DNS verification log to confirm past Google Analytics / Search Console ownership?
