I came across one website that had a flash intro. Flash is used a lot on restaurant sites. I guess it looks fancy and people love it. I don't know. However, as you may know, flash does not show on iPhones. Which is what I have.
When I checked the site on my iPhone the screen was just white for a 12 seconds (I counted). Then it went to another page. Which of course looked horrible on a mobile phone.
HERE IS THE TIP:
I looked at the bottom of the site and it had a "site designed by" link. So I clicked on it. It took me to a god awful looking website of a local web designer. And wouldn't you know, they have a "Portfolio" page.
So I clicked on it and there were several more prospects that are going on my contact/visit list.
Most sites will have this "site designed by" link at the bottom. And chances are, the other sites that designer made all will have a similar look/layout.
So, if you find one bad site, you find several.
Btw, I'll be walking into these restaurants with their site already to go on my iPhone and showing them. Then I'll show them what it could look like.
Hope that helps. If you found this useful, feel free to hit the "Thanks" button.
