You have a blog for a while now, and you publish regularly. Wouldn’t it be good if you had a book published as well?
A service that converts blogs into books, by taking the best and most popular posts and rewriting and editing them to become a coherent book. Services might also include, printing, distribution, ebook, Kindle, Amazon, etc.
See others’ mistake and learn.
A website that regularly publishes articles only about mistakes in different areas and subjects. Kitchen design, CVs, buying a house, going on vacation to Greece, etc.
People don’t realize how weak their passwords are.
Publish passwords that were hacked (and are freely available- no hacking done here) on a dedicated website, so that people can see and learn.
You need the sun for your body to create vitamin D.
A function of a smart watch that is set up for your skin type (so you don’t get sunburns) and measures the daily dosage of sun you get. During the day you can see how much sun time you still need (also based on your location, time of year, and time of day), and how many international units of vitamin you need to take that day if you don’t get any more sun exposure.
If you believe that you stumbled upon a special (mistake) price that might go away, you’re more likely to take it.
First show the higher regular price. Then show them a lower price – as if by mistake. You can do this by taking them to a different web page and then back, displaying the “mistake” lower price on their return. You can even use the two prices on the same page, by having a higher priced button on the top of the page, and a “mistake” lower price lower down the page.
For items that vary in price (like airline tickets), first show higher price, then lower one so the customer has an incentive to buy now so he won’t lose the lower price opportunity
