When separate web pages are combined into one, each potentially with its own scrollbar. You know you’re on a framed website when part of the page scrolls while the rest of the page stays in place. Search engines don’t like frames. A framed web site is at a severe disadvantage compared to non-framed sites in terms of search engine marketing. Most search engines support frames, but only, as Google says in its FAQ section, “to the extent that [we] can.” Searchers clicking through to a framed page from search results sometimes end up on an orphaned page. You can use <noframes> in HTML to make the page indexed normally by the crawler.
