You don't want people scrolling too much; someone important might not have the time. Delete entries that are not significant to your career and business. Instead, expand your profile with your most relevant skills and expertise as well as your most current products and services. Elaborate there.

There is no need to follow the formula of creating one experience entry for each job title you have held. Take the space you need to communicate your accomplishments by creating multiple entries for every role you have performed within each job title. You don't need to worry about overlapping dates either.
