Optimization Of The Pdf File
Like the URLs of the pages of your website, the names given to your images … the name of your PDF file must be optimized for SEO with keywords representative of your content.
Like the metadata tags of the pages of your website (title tag, description tag …), fill in the metadata of your PDF document. Just edit the properties of your file from your PDF authoring software.
Like any page of the website, optimize the size of your file: if your data is too large, cut it into several files or compress your PDF file.
Like the hypertext links of your web pages, optimize the links included in your PDF file with the right keywords as well as the links from your website to your PDF files (especially not “click here …”). In your document, add links to pages of your site, a link on your logo to your site, indicate the address of your website … Indeed, the user who finds your PDF document and wants to know more will be able to consult your website.
Avoid the provisions of your textual content in columns, and the indexing robots may misinterpret it.
Check that your document is not protected, the textual content must be selectable (copied/pasted) and not be an image in which case it would not be indexable by the search engines.
Export your file in a most common PDF version and not necessarily the latest version so that it can be read by users who do not have the latest update.
Beware of duplicate content, that is to say, identical or very similar to those pages of the site.
