We definately have google to thank for this. With their highly developed search algo it means you can tell it that you want “baked beans in spicy sauce with a sausage on the side” instead of just “beans”. It’s nice to see that searchers are picking up and taking advantage of this.

It also means there is a lot more room in each market for webmasters. If you can’t rank well for one search phrase, you can target another one and still rank well.
