Adding metadata to PDFs
You must add metadata to your PDF to ensure it is correctly indexed by search engines and displayed correctly in search result lists. To add metadata to your PDF:
- Open the PDF in Acrobat (not the Reader) and select File > Document Info > General.
- Enter the metadata in each of the four fields:
- Title - this field must contain the full title of your document (not the PDF filename).
- Subject - this should be a concise (i.e. fewer than 255 characters), free-text description of the content and/or purpose of the document.
- Author - this field should always contain the words: 'Department of Natural Resources and Mines'.
- Keywords - this should contain keywords and/or phrases which succinctly describe the subject and topics covered by the content of the document. Use semi-colons (;) not commas (,) to separate individual keywords and phrases.
- Click OK to apply the metadata to your document.
- Select File > Save As and ensure the Optimise checkbox is checked. Click Save.
Note: If you just use 'Save' (i.e. don't use 'Save As') the PDF will become un-optimised.
