Maybe this has never been your experience, but it has been mine, so I thought I would share,  just in case your website's success has been hindered by something so rudimentary. Very easily remedied when you think about it.

Very frustrating when it happens, but it's really not such a mystery.

If you're getting traffic to your site and not the sales you should, consider this:

Maybe people are coming to your site and not finding what they thought they would find. Maybe you're not using the right keywords.

There are 2 kinds of keywords: commercial and non-commercial. Commercial keywords directly attract people who are shopping for something, such as a car heater or a portable air conditioner.  In this case, the commercial keywords to use would be "car heater" and "portable air conditioner" respectively.

A non-commercial keyword attracts people looking for information.

If your site sells coffee makers, then "coffee makers" is a commercial keyword. When people enter the phrase "coffee makers" they should land on your sales page.  On the other hand, "how to brew coffee" is a non-commercial keyword, and people searching it are looking for information. Use that keyword on an article page on your site.

If people don't find what they expect, they'll leave your page. Give people exactly what they are searching for.

 If your pages are confusing, verbose, or there's too much going on, people will leave your site.

Plant subliminal messages through graphics, suggesting comfort level, competency, and desire to take action.

According to Chris Malta of Worldwidebrands.com, a Home Page done right will convert visitors into sales like crazy.

"Some of the best Home Page designs, for example, have very little text on them. They'll have a header background that establishes comfort by showing people they're in the right place. A logo that establishes professionalism. A contact image that shows legitimacy, an image showing a person using the product, that establishes desire. That image will also push your visitors eyes to category images that drive action."

Most of you know this already, but it doesn't hurt to be reminded, and I hope it helps the newbies. It can be maddening when your site doesn't meet your expectations.
