Well anything really.
I think it is a good idea to try and stick to your original keywords but that is not a hard and fast rule.
Also keep an eye on your images, as with your url people can pin your images to Pinterest making backlinks. If you remove those images it will also make broken links...
Here are some ideas for updating your old content:
- Check for outdated information such as old contact details, company names or product names that have changed.
- Check your CTA and see if you can improve it
- Add more content, elaborate on some topics
- Add more images where possible
- Add more relevant internal links (both to this post from other posts and to other posts)
- Add more external links to high authority websites
- Embed a Youtube video if it doesn't already have one
- Optimize your meta title and description
