In the film Blazing Saddles, there’s a scene where the bad guys are coming to destroy a western town – so the townsfolk build a big cardboard replica of the town a little ways away and direct the bad guys to that one. The houses are all fronts, the townspeople are wooden cut-outs with bobble-heads, and so on.
That may fool movie bad guys, but it won’t fool your customers. SEMblog brings up this point in talking about best UX practices for SEO. If you have traffic coming in from organic searches, chances are good they’re going to hit a post on your blog or a sub-directory further down on your site map, rather than the first page. Lots of other good user-experience tips there too.
