Hi Designer,
As others mentioned, Google is #1.
With my clients, Google accounts for 80% of our pay per click advertising budgets, Yahoo 15%, and MSN (Live) 4%, and Ask at 1%. That also goes for the amount of organic traffic we receive, with very small sprinkles from 2nd / 3rd tier engines.
Not all sites have a Google ranking.

Many reasons for this, even older sites. I find many sites that don't even have basic, best practice optimization. Also, new websites face a challenge of getting found and ranked, often referred to as the Google Sandbox effect.
Rankings on G, Y, and M change all the time, but major updates usually shake things up a bit. WebmasterWorld, the largest online forum for everything web / internet related, used to name major Google updates like hurricanes! Esmerelda, Florida, Bourbon, Jagger, just to name a few... These major updates are also referred to as the Google Dance.
Don't get confused about the changes in rankings, just be consistent in your application of on-page SEO factors, and continually build links within you vertical. One-way inbound links with good anchor text (keywords that you see on a page that link to a website) are the most coveted links. When I say within the same vertical, I mean within your same industry. If your site is about cars, and you get links from a sewing site, there is very little link juice that passes.
Does that help?
