There are several ways to add meaningful pictures to your business.
Put pictures into an exposed position on your store locator and local pages. People react very positively to pictures. Add one large picture that catches the attention of your visitors. In addition visitors react positively to more detailed pictures. On the front page you can not show more than 3 or 4 detailed pictures. Add a picture carousel where people are able to swipe and see more pictures. Measure which pictures were clicked by your visitors. This will help you to select meaningful pictures over time.
Make sure that you add pictures where you own the copyright. Pictures done by your agencies or your employees for example.It is also important that pictures are of high quality and that height and width of the pictures are not changed while uploading. Pictures should be updated regularly to reflect seasons, product updates and latest brand campaigns.
