You know he is interested in widgets because he searched for them. Don't distract him from the sale. You have maybe got a couple of minutes to close the sale before he goes away. In that time, you need to convince him that you are trustworthy, because he is about to buy something from you. That is why it essential that everything you have done up until now is trustworthy.
Brands are about trust.
Build, manage and protect your online brand with care. Spamming search engines, getting unfairly promoted, delivering inappropriate content - none of this promotes trust and it will lead to lower sales and permanently damaged brands. Think less about hits and more about business. Think about high closure rates rather than large log files. That way, your site is more likely to achieve its mission.
