In one sentence, describe what the following article is about:

One of the key aspects of becoming a successful internet entrepreneur is to put the needed tools onto the website. Allow customers to get involved with the business and make transactions easily and conveniently. Besides, the shopping cart is a feature expected of all online marketplaces now, so it would be a glaring omission to potential customers. Customers need a way to buy, but the business also needs a way to track sales and identify target audiences. Complex web tools and good leadership can allow for a sophisticated marketing plan. Use your web skills to discover and target the features your customers want to see. You will have to determine what part of your business model you want to investigate, who you will ask and how, and a sample size. This is a rapidly expanding aspect of online businesses, even though phone apps don’t function essentially different from web browsers. One of the reasons is that ad block software is not compatible with apps. This means that people who buy ad space with you will know that users will see their message. Develop an app for your business to attract potential investors while this technological loophole still exists.

Summary:
Add shopping carts or other infrastructure. Use surveys to drive future business. Develop smart phone apps.
