When it comes to SEO, content is much more than text. In fact, content includes everything that can be optimized on your website, including graphics, photographs, videos, PDF files, etc.
Don't forget to:
- Use proper ALT tags for your graphics and photos.
- Use proper keywords in your image names. For example, "pool-cues.jpg" is much better than "pc123.jpg".
- For videos, make sure you're completing all file properties for the video using keywords where appropriate. For YouTube, you'll want to create a link back to your website.
- PDF files are often overlooked for optimization. They should also include a proper title, description, keywords in the PDF file properties.
If you're overlooking these elements, you're missing out on some potential SEO opportunities that may be making a difference in keyword rank.
