Is it better to show a blank space or a wrong guess when data is missing?

I ran into this exact headache while pulling company details from random websites.

Some pages have their logo hidden in weird spots or completely skip a clear description, leaving my script scrambling. At first, I tried forcing smart guesses just so the UI wouldn't look empty but it backfired when the tool confidently displayed the wrong info to users.

Now I'd rather just leave a clean "not found" or let the user fill it in manually than show fake confidence. How do you handle UI states when your scraper comes back empty handed?
