If you cannot see links or meta tags, the search engine spider have no way to move forward on your site or know what it is about. Webmasters use frames because it is the simplest method to update your website. However, making their job easier, can make yours harder. One way around this is to use meta tags to offer the information to the spiders. Also, you have to have an understanding of how meta tags effect Internet Explorer and Netscape.
Different tags react differently on both browsers.
The most effective way is to redesign the site without frames. If you are having this problem, we have solutions and we would be glad to discuss them with you.
