How to optimize PDF files for SEO?

One of the cornerstones is to make sure that the PDF name corresponds to its content. For this purpose it’s worth using keywords that don’t only indicate what’s in the file. But also increase your chances of reaching high positions in the search results.
However, keep in mind that the title should be between 50 and 70 words long. The link itself needs to be as natural as possible, with no keyword stuffing accepted.
When devising your PDF file name, get rid of special characters, underscores or spaces. Otherwise, the generated URL will contain elements that aren’t URL-friendly.
2. Optimized meta title and description
Both title and description of a PDF file serve the same purpose as title and meta description of HTML. Consequently, when doing SEO for PDFs, take into consideration both users and search engine algorithms.
The title of the PDF document itself may differ from the name you assign to the document. It’s worth benefiting from the potential of long tail keywords related to a given field or inflected forms of key phrases.
When it comes to the description, it’s crucial to apply CTAs. We are talking about phrases like “check out”, “see” or “find out more” that encourage users to click.
3. Unique SEO texts
Ensure proper text optimization. It must take into account highlighting both headers and keywords related to the subject. In this way, you will encourage users to browse the text and find appealing information.
On the other hand, it will notify the search engine robots about the hierarchy. And, the most important pieces of content. Provide a table of contents that helps to categorize the text and makes it easier to navigate the document.
SEO for PDF files is based on the same principles as SEO for standard HTML pages.
However, text optimization isn’t enough. Make sure that your content is unique. Don’t copy it from other websites or sources. If not, the search engine will see your PDF file as duplicate content.
4. Appropriate internal linking
Provide internal links that redirect to specific subpages of your website. Search engine robots are able to recognize the content of the document and assign it to the text on the page.
Moreover, it’s an excellent way to increase website traffic. Also, notify the robots which sections are particularly relevant.
Don’t forget to apply an appropriate anchor that corresponds to the discussed subject matter. It may be crucial for Google robots.
5. PDFs saved as text files
To make sure that the search engine indexes your PDF, you should save the document as a text file. It’s not the best idea to publish content in the form of an image.
Google robots won’t cope with the indexation. Consequently, the file’s visibility in the search results won’t improve.
6. Friendly URL
This point should be kept in mind already when devising the file name. Get rid of special characters, capital letters, spaces or digits. Instead, go for a concise URL with a keyword.
A friendly URL can be easily memorized by users. In this way, they can effortlessly access the file that is of interest to them by entering its name.
7. Low file weight
Decreasing the size of the PDF file is another important ranking factor as it enables faster loading. Why it is relevant? The lower the file size, the quicker it’s indexed.
This means that it will reach a wider range of recipients. Consequently, before creating the document, compress all the necessary images or other graphics.
8. Optimized ALT tags
When creating PDF files, it’s advisable to remember appropriate image optimization. This means adding ALT attributes of all graphics included in the document.
PDF files are mainly about manuals, price lists, reports or presentations with numerous images. So, ALT attributes help Google robots to categorize the graphics correctly and index them faster.
