• Google Crawler: A ‘Spider’ crawling on WWW
• Operates ‘really really ’ fast
• Data Updation = Information fed
by Google Crawler
(Updation frequency increases on National holidays,
low internet traffic periods…)
• More hit means higher probability of appearing your
website above others• Want high on rank? Use ‘extensively searched words in
Internet’ and cross-links

Key to swift search: Think like a Google Crawler…

– - (minus sign): Words succeeding minus sign will NOT be shown in query
results

know what it is (Caution: Position of asterisk is very important. Payattention while using it)
