When your text paragraphs comprise multiple bulleted levels, you can just use the defaults that PowerPoint provides. This takes care of all paragraph indentation issues. However, to have more control you have to use your own indentation values. This option makes your text look consistent and clear, as per your needs. Indent Markers visible on the Ruler are probably the easiest way to achieve such structured results. However, this method does not let you precisely position the indentation since you just drag and pull the Indent Markers rather than setting them up via an exact numerical value.
