Google Sheets beat Microsoft to the punch and introduced a Checkbox as one of the Data Validation options. You can go to Insert > Checkbox to quickly create one, and you can customize it by going to Data > Data Validation. I've updated most of the Google Sheets versions of my checklists to use that feature. I hope Excel gets smart and introduces a similar feature some day.
Of course, you will ‘sell’ this offer with professional sales copy, some great headlines, and maybe even some bullet points. But the general idea here is to introduce yourself to this new cold traffic visitor, let them know what you are about, let them know that you can help them, and convince them that the first step to solving their problem is to opt-in to your free offer.
Don’t worry about making everything perfect at the outset. As the old saying goes, done is better than perfect, and the sooner you launch your membership site, the sooner you’ll find out if it’s what your target audience wants. It’s fine to return to this step later and work on making your membership website look more professional once you've got some traction.
First, from the product page, the Add to Cart button should be highly visible. Next, the shopping cart should be easy to locate—usually positioned in the sidebar, or the top-right. The checkout page should be super-easy to access, and never more than one click away, allowing a visitor to bypass the shopping cart if they want. Finally, the checkout fields should be logical, and kept to a minimum.
Checklists have been used in healthcare practice to ensure that clinical practice guidelines are followed. An example is the WHO Surgical Safety Checklist developed for the World Health Organization and found to have a large effect on improving patient safety and subsequently found to have a nil effect in a cohort of hospitals in the Province of Ontario in Canada. According to a meta-analysis after introduction of the checklist mortality dropped by 23% and all complications by 40%, higher-quality studies are required to make the meta-analysis more robust. However, checklist use in healthcare has not always met with success and the transferability between settings has been questioned. In the UK, a study on the implementation of a checklist for provision of medical care to elderly patients admitting to hospital found that the checklist highlighted limitations with frailty assessment in acute care and motivated teams to review routine practices, but that work is needed to understand whether and how checklists can be embedded in complex multidisciplinary care.
