One suggestion I have is to continue to split test your ad copy in Adwords. Sometimes it only takes a small change to your ad copy to begin to get a decent CTR. You don't have to pay $0.50 / click if your CTR is healthy. This is how your competition is doing it.
I am a firm believer of NOT putting your prices in the ad itself. I've found that this actually puts off visitors as you've already "given away " the information that they are looking for without visiting your site. They will just go to other sites and soon forget your price. Let your website do the selling for you. The idea of the ad is to get them to visit which in turn lowers your per visitor advertising cost.
Use a catchy title such as "Great Truck Cover Deals" , or something along these lines. 2nd line.. "Check Out Our Unbeatable Prices Today. Fast Shipping. "
Always use a call to action such as "buy today" or "find out now" and always state in your ad body any specials or anything else that "sets you apart from your competition"..
Always us All Caps for the first letter in each word of your titles and descriptions. Most of my tests confirm that this gives a better CTR. See my example above. I also believe that capitalizing your URL is an improvement as well. Example would be BestTruckCovers.com . It is easier to read and improves your type ins.
Anyway, good luck and send some of that bonus my way if any of this works out ; ) .
At every reload, the browser puts up a warning that the page contains mixed content (secure AND unsecure items)
All of this would seriously frighten the average customer.
In Netscape it isn't so bad but the security warnings persist.
I think the biggest problem you have (after the https question) is the image download times. You might consider using a more highly compressed jpeg, you will lose some quality, but on the Internet, speed is the utmost importance. Try to get your image files below 10k bytes. (Consider using a thumbnail linked to a larger version)
Good luck - apart from these points I think it's a good site. Customers are easily frightened ;-)
You'd be undermining your company to do this. While you might look good and get a promotion for increasing Internet sales, you'd be canibalizing your wholesale sales. Good luck when your boss figures out the cost of your "improvement" to sales.
What is going to get you more sales? One ad sending customers to your directy, or 10 ads sending customers to your dealers?
Cache Graphics Use the Expires: header to tell HTTP clients they can cache those highly repetitive graphics instead of continually having to retransmit HTTP If-Modified-Since requests to see if they changed since 5 seconds ago when I last downloaded them.
Ungraceful ActiveX Degradation go through the order process with ActiveX. Then with ActiveX set to "always ask". Then with ActiveX set to "off". Nuff said.
Below the Waist on First Date that's how it feels when a company makes you setup an "Account" just to buy one damn item. Making an account should be an option. Insisting on it totally kills the mood for an impulse buyer. I should be able to do the complete order in one page, two at the most.
And Then They Never Call you'll send me the tracking number if I email you and ask real nice? Yeah, right. How about you automatically email me the tracking number right away, and help keep me from suspecting you're actually a teenager running this out of his parent's basement?
The Hidden Zinger of Death have you really been working on this 2 years without hearing that customers want to know the Full Price Including Taxes and Shipping before they start giving you personal information? Ever wonder why the big e-commerce folks have so many "free shipping" deals? Because it can make a big difference in consumer behavior if they don't have to wonder whether or not they're looking at the real price. Go do an online price comparison for a popular digital camera. Pick the absolute cheapest seller, then go try to buy the camera. Notice how it turned out that it wasn't even close to the cheapest, after all? Notice how you gasped when you saw that shipping and (the dreaded) handling was $35 for a 1-pound package shipped the slowest possible way? That's what you subconsciously tell shoppers you're going to do to them when you don't make the taxes and shipping 100% up front, plain, visible, and reasonable.
IMHO :-)
