What's a security warning? It's an alert window shown to your customers whenever the browser detects that something on the page is not secure, but the URL is a secure one (https). I'm sure you've seen a security warning many times. It looks like this:
It bugs you (and maybe scares you) when you see it... and it bugs your customers too.
Where to look? Here are the common culprits:
- Google Analytics (or another, remotely hosted Web statistics service)
Make sure that the code snippet that you grab from your Google Analytics account is the HTTPS version, and not the HTTP one. I've seen a lot of store owners make this mistake, because Google by default gives you the HTTP version. The same is true if you are using a service other than Google Analytics. They pretty much always allows you obtain a secure version of the piece of code to be placed on your page.
- Google AdWords or Yahoo! Search Marketing conversion tracking
Same thing here. Make sure you get the HTTPS version of your Pay-Per-Click conversion tracking code. Typically this code ends up on the last page of the checkout process, so the bugging security alert won't prevent customers from ordering (they've already placed the order). Still, it just doesn't look good :-)
- CSS and JS files
- Flash elements
If you have any Adobe (Macromedia) Flash elements on your page, make sure that the code that is added to the page by Dreamweaver or another HTML editor to handle the Flash file does not contain HTTP URLs. It often does.
So check your site (or have your Web designer double-check his/her work). Remove those security warnings: no reason to give your customers one more reason not to stay on your Web store!
