"Perfect Search Engine would understand exactly what you mean & give you back
exactly what you want"
- Larry Page, Co-Founder & CEO, Google Inc.

1. Crawling & Indexing
             Crawling means following links from page to page. Site owners chose whether they want their sites crawled
              Index includes text from millions of books from several libraries & other partners

2. Algorithms: Apply Programs & Formulas to deliver best results possible
             - Spelling
             - Autocomplete
             - Search Methods
             - Synonyms
             - Query Understandings
             - Google Instants

3. Rank the results

4. Fighting Spam
           - HIDDEN TEXT AND KEYWORD STUFFING  
           - spammy user-generated content
           - Parked domains: placeholder sites with little unique content
           - THIN CONTENT WITH LITTLE OR NO ADDED VALUE
           - UNNATURAL LINKS TO A SITE
           - "SPAMMY" FREE-OF-COST HOSTS AND DYNAMIC DNS PROVIDERS
           - CLOAKING AND SNEAKY REDIRECTS
