Google is the most popular search engine on the Internet. But you probably didn’t need me to tell you that. According to April 2008 stats, Google is used by about 60% of US Internet searches (Yahoo is #2 around 20% and MSN around 10%, AOL and Ask are about 5% each). They maintain their huge lead because they return the most relevant results for a search. If they didn’t, we’d use a different search engine. So how does Google do it? How do they know what are the best sites to refer you to for your search?

A Cola Analogy
I grew up going to our neighborhood pool every summer. One of the things we’d always do is carry some change for ice cream and knock-off brand “Check Cola” during “Adult Swim” times. Winn-Dixie sold Check Cola and I loved it as a kid. Today you can get all kinds of generic cola, but when someone mentions “cola”, the two big brands usually come to mind: Coke and Pepsi.
We know what makes a cola drink, but we don’t know the specifics of what makes a cola a “Coke” or a “Pepsi”. Those are trade secrets. It’s the same with search engines — we know what makes a search engine, but we don’t know what makes a “Google” or a “Yahoo”. However, Google has told us how they separate themselves.
Keyword Matching
The most straight-forward variable in the Google formula for their search engine result page (SERP) is matching the word(s) you use for your search compared to the words on the web page. This of course makes sense. If you search for “college football”, you’d expect web pages to be listed that are about college football!
Google PageRank
The next part of the Google formula is something they call PageRank. Google explains PageRank:
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at considerably more than the sheer volume of votes, or links a page receives; for example, it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.” Using these and other factors, Google provides its views on pages’ relative importance.
This is where the “secret formula” really kicks into complicated understanding. Every link going to a website counts as a vote but not all votes are equal. If site A has a link that says “a college football website” and the link goes to site B, then Google gives site B a slight bonus for searches on “college football”. If site A is already about college football, then site B gets an extra bonus. And if site A has a high PageRank, site B benefits from that also.
Google is trying to determine what websites are trusted and authoritative on particular subjects, keywords, and phrases then return those sites as relevant. But it doesn’t stop there. PageRank is actually just a part of something bigger…
Page Quality
In a recent blog post from the Official Google Blog, they reveal PageRank is part of determining the overall Page Quality:
PageRank is still in use today, but it is now a part of a much larger system. Other parts include language models (the ability to handle phrases, synonyms, diacritics, spelling mistakes, and so on), query models (it’s not just the language, it’s how people use it today), time models (some queries are best answered with a 30-minutes old page, and some are better answered with a page that stood the test of time), and personalized models (not all people want the same thing).
Ranking High in Google
So how do you go about getting all of this to work together? Part of it is having a web page that is about what a person is searching for. The other part is becoming an authority on that subject. A large part of any Internet Marketing campaign will include Search Engine Optimization (SEO) and there are a lot of things that go into it. Google tells us how to create a Google-friendly site, but the way I’ve described it for years is:
