Small web sites with only 1 or 2 pages set themselves up for failure, simply because they usually don't have enough content of interest. There are of course exceptions, where the 1 or 2 pages are each as long as a book. But these are awfully frustrating to read, and no one will be satisfied with them. Most often 1 or 2 page sites are simply too short to provide any useful information, so the search engines don't take them seriously. Among other factors, the search engines examine how deep a site is. The more meaningful content present, the more weighty the site is viewed as, and the more importance it is given.
