Google is the most popular search interface on the planet, with a 65.2% share of the search engine market and over 3 billion searches each day. Understanding how Google works is essential to search engine optimization, the process of obtaining a high-ranking placement in search results to dramatically increase the number of visitors to your website for online brand visibility and sales benefits. Which brings us to the important question : how does Google search work?Web explorationGoogle uses what it calls a ‘Googlebot’ to crawl the World Wide Web, following links from one web page to another. Starting from its first crawl status, Googlebot looks for new sites, changes to existing sites, and invalid links.Data organisationAfter crawling the web, web crawlers report on the pages visited to update Google’s 95 petabyte index (1 petabyte = 1 000 000 000 000 000 bytes. Googlebot processes most types of content, except for some, like dynamic pages and rich media files.Data presentationGoogle then analyzes the content with certain factors in mind, to present the most relevant search results. These factors include :- Type of content (search term)- Quality of content- Freshness of content- Legitimacy of the site- User’s location- Website name and address- Links pointing to the page and the value of those links- Synonyms of the search words/terms- Social media promotionsBased on these factors, Google sets a score for webpages, which determine their PageRank. A higher PageRank ensures a higher position in Google search results.Tips on getting more out of GoogleSome search methods are more efficient than others. They bring up the relevant results you seek and cut down on the time to find the one or more websites containing the content you want. Here are some useful tips you can use for your daily Google searches:Exact phrase matchOperators help you get specific results as opposed to generic ones. For example, say you have to prepare a consolidated report of articles on Greece’s debt situation appearing in leading financial website Bloomberg.com.site:bloomberg.com ~ “Greece debt” will throw up all the articles on this topic on the websitesite: bloomberg.com searches only the pages of this website“Greece debt” searches for the exact phrase and not each word “Greece’ or “debt” separatelyIf you want an exact phrase match, just put it in quotes.Title searchUse “intitle” to match only the text appearing in the specific title you want to search for.site:amazon.com intitle:”the social network”Excluding a specific wordUse the (-) operator to exclude a word.
