When it comes to search rankings, most people who think about it feel there is an easy way to get those rankings. In short, they feel they make a tweak and bam, their rankings go through the roof. When it doesn't happen, they feel that they are missing out on a silver/magic bullet.
Google's John Mueller said in a Google Webmaster Help thread that there often isn't a magic bullet. That often a single tweak made to a web site will not lead to significant ranking changes for the better. John explained that there are hundreds of ranking factors, so making a small tweak won't likely lead to increased rankings.
