Spamming is the multiple use of keywords in order to make Web pages seem more relevant. In the early days of search engine use, many people would use spamming as an effective means to secure higher ratings on search engines. But search engine technology has grown more sophisticated. This approach is frowned upon today. In fact, most search engines are now programmed to ignore pages that use spamming.
Frames are an attractive way to design a Web site.
But they can also cause problems when dealing with search engines. Most search engines will ignore information contained within frames. Another idea is to create a non-frames section of your site to separately index your site. One technique that used to be quite common on Web pages was to use the comments area of a site's source code to embed repeated keywords. Today, most search engines ignore these comment areas.
