Search engine optimization (SEO) is the process of optimizing web pages or entire sites to make them more search engine friendly, thus improving their rankings in search results. Google can crawl, index, and classify PDF files, but SEO for PDFs requires a different set of tactics. To ensure your PDFs get the most visibility, follow these 13 tips. PDFs are displayed in Google search results with a PDF tag and are converted and indexed as HTML.
For PDF files with images of text, Google uses optical character recognition (OCR) technology to convert the image into text. Images in PDFs are also indexed in image search results. Most PDF files lack the proper metadata that Google searches for. Saving a text editor or slide show as a PDG file doesn't automatically add the correct document properties.
You can use Adobe Acrobat to map some of that metadata, but most people skip this step before publishing the PDF to the web. Setting the blog post's canonical tag to be self-referential is one of those SEO best practices to avoid any duplicate content issues. Their SEO Starter Guide PDF has 3.37K links from 754 referring domains and they do a good job of conveying that value to other pages by linking from the PDF. Search engine bots can crawl, index, and rank them, but they lack the data needed to be ideal SEO assets for content producers. Most of the on-page SEO elements that you're used to seeing in HTML have an equivalent version in PDFs and are used the same way you're used to.
