Now you can clean up your site, once you have found lines with errors. If you are fortunate enough to have a good HTML editor that will count out lines, then you need not hunt for them, but this is a good trick to try if you don't get an accurate line count.

2nd Rule - Errors. The king daddy of site design taboos in my book. Have you ever had this one happen to you?: You've found perfect price for perfect gift. You went to check out and, poof: 404 error. You click back button and try again; still no dice. Do you call their customer service number and take a chance of launching yourself into a black hole? Personally, I will search for another site that sells same product. The error site just lost a sale and possibly a repeat customer. Limit your errors. Not just 404's, but broken graphics and even misspelled words. Complexity is a big one here. The more complex your site design, higher chances of an error occurring. Keep it simple.

3rd Rule - Logos and Graphics. Another problem that can make your site look very unprofessional. This is a place to not skimp. Find yourself a good graphical artist and invest in a good logo. Don't get some huge, complicated logo that will take forever to load. Forget about weird neon colors, animated animals, flames, fonts, etc. Keep your graphics simple, sharp and professional.

4th Rule - The little things. There are probably hundreds of things that can scare traffic away from your site. Here are a few:

Updated dates - Don't include them. Many people have sites that will not need to be updated on a regular basis. Including an updated date can only do one thing: make your site look outdated.

Site Counters - Ugh. I still see these every now and then on seemingly respectable sites. "Hmmm, they've only had 3,000 visitors since August, 2001. There must be something wrong with them." It may just be that counter is broken, but how are you going to tell them that?

Too Many Ads - Link pages are great, but there is a place for them, don't crowd your navigation or product pages with too many ads. It's ok to sell a few spaces but don't draw attention away from your products/service/content.

There are a lot of things to remember when designing your web page, but most importantly you need to ask yourself, "Would I buy there?".
