In 2001, Google began indexing PDFs. This format is frequently used in academic, corporate, and administrative sectors. Daily, millions of documents are indexed by Google. Examples of documents include pages of content, photos, and PDF files. Frequently, PDF file optimization needs to be remembered. That represents a lost opportunity since, like conventional webpages, PDF files possess the capacity to drive significant traffic.
How PDFs are Handled by Google?
Google results from searches for PDFs have a PDF tag. PDFs are transformed into HTML and indexed accordingly and appropriately. When there are text images in PDFs, Google’s Optical Character Recognition (OCR) algorithm converts the contents of the picture into text. In image search outcomes, pictures in PDF format also get indexed.

Fast Web View
