I use Norton Internet Security and when I do a search, it will show the results with a little green circle with “OK” in it, meaning that Norton has visited that page and it’s not a threat. If they haven’t visited it, you can get them to and, thus, show the green “ok” symbol by claiming the site.
If I’m looking for something, I pay attention to that little green circle, and I’m sure other people do, too, especially if they’re planning to shop.
If I manage your site, all you need to do is setup an account with Norton (link above) and then give me your login info and I’ll take it from there.
Any way we can add even just a bit more credibility to an ecommerce site is good.
Addendum – the same applies to McAfee. http://www.siteadvisor.com
