Split Second Search
#1 Before you search
- The journey of a search query begins long before you type your search into Google. We use software robots, known as web crawlers or spiders, that find web pages to include later in Google search results. Google's
software stores data about these pages in data centers. The web is like a book with trillion of pages, and our job is to index that book.
- Our index is well over 100.000.000 Gigabytes.
- We've spent over 1 million computing hours building the index so far.
#2 As you search
- When you start your search, that's when Google's algorithm begins to find the information you're looking for.
- The search query travels on average 1.500 miles to get the answer back to you (and may hit different data centers around the world along the way), at a speed that's close to the speed of light, hundreds of millions of miles
- As you type your query, you'll start seeing predictions of searches you might be looking for and results showing up, without you having to hit enter. It saves you time and gets you to your answer as quickly as possible. This
is what we call Google instant.
- The algorithm looks at your query and uses over 200 signals to decide which of the millions of pages and content are the most relevant answers for that query. Google finesses its ranking algorithms with over 500
improvements per year.
- Examples of signals include: 1) The freshness of content on a website; 2) The number of other websites linking to a particular site & the authority of those links; 3) Words on the web page; 4) Spell check; 5) Synonyms
of your search keywords; 6) Quality of the content on the site; 7) URL & title of page; 8) Whether the best result is a webpage, image, video, news article, personal result, etc; 9) Personalization; 10) Results recommended
by people you're connected to.
- Results are ranked in order by relevance and displayed on the page. In addition to showing you results instantly, we also render a preview of those web pages which you can see by hovering on the arrows to the right of
the result, so you can quickly decide if it's a site you want to visit.
- There are billion of searches each day on Google.
- The instant previews load in 1/10th of a second on average.
- Since 2003 Google has answered 450 billion new unique queries, searches we have never seen before.
- 16% of searches we see every day are new.
