How to know a PDF page has text (invisible / we can search) (from OCR or it was created by Word, Excel or any other tool

I will receive some PDFs where some pages can have text (invisible) so we can search (example: PDFs created by OCR tools, or Office tools or others). And other pages where it will be a scanned image without ocr contents , so we can´t search. For the pages without OCR contents I need to apply OCR and create the hidden text in the specific locations (this I know how to do). My question is: how to detect a page has or not invisible text?

Thanks in advance
