1 of the biggest mistake people make while using power point ... is that they let their imagination fly .... and put animation in their slides ..... avoid any animation if u want use only dissolve .... rest i think paul has summed it up quite nicely ..... dont put too much text in the slides ..... make the presentation (ppt) as brief and informative as possible ..... use a subtle background .... also dont forget to put the logo of ur company
another very good suggestion by mAV3 , never ever use animations and sound effects in professional ppts and use short , to the point statements , dont fill ur pages with text
our professors in college used to say " FOR PERFECT PPT PRESENTATION , WRITE LESS AND SPEAK MORE " because frankly speaking and trust me no one is gonna see ur ppt or what is written in it , they will be interested in what u speak
