Final answer:
You can add footers to all slides, including the title slide, and exclude the slide number from the title slide using options in the presentation software's Insert tab and by editing slide master settings.
Step-by-step explanation:
Yes, you can add a footer to all of the slides in a presentation, including the title slide, and still have slide numbers on all slides except the title slide. Most presentation software, such as Microsoft PowerPoint, allows you to customize headers and footers within the slide master or slide layout options. To add slide numbers, you will typically need to insert them via the Insert tab, but you can choose not to display them on the title slide by either deselecting the option for numbering on the title slide or editing the slide master for the title slide to remove the number.
For instance, in PowerPoint, you would go to the Insert tab, select Header & Footer, and in the box that appears, you would check the box for Slide number. To prevent the number from appearing on the title slide, you'd check the box that says 'Don't show on title slide'. This allows you to have consistent footer content across all slides while keeping the title slide free of a number.
