What is a Search Engine?
• Definition: An internet-based tool that searches an index of documents for a
particular term, phrase or text specified by the user. Commonly used to refer to
large web-based search engines that search through billions of pages on the
internet.
• Different than a Directory
• Common Characteristics:
• Spider, Indexer, Database, Algorithm
• Find matching documents and display them according to relevance
• Frequent updates to documents searched and ranking algorithm
• Strive to produce “better”, more relevant results than competitors
Examples popular Search Engines
How Do Search Engines Work?
• Spider “crawls” the web to find new documents (web pages, other documents)
typically by following hyperlinks from websites already in their database
• Search engines indexes the content (text, code) in these documents by adding it
to their databases and then periodically updates this content
• Search engines search their own databases when a user enters in a search to
find related documents (not searching web pages in real-time)
• Search engines rank the resulting documents using an algorithm (mathematical
formula) by assigning various weights and ranking factors
Search Engines statistics
1. Google – 41.6%
2. Yahoo – 31.5%
3. MSN – 27.4%
4. AOL – 13.6%
5. Ask Jeeves – 7.0%
% bases on usage
Why is Search Engine Marketing important?
• 85% of all traffic on the internet is referred to by search engines
• 90% of all users don’t look past the first 30 results (most only view top
10)
• Search engine traffic is low and websites aren’t indexed because they
are generally poorly optimized
• Cost-effective advertising
• Clear and measurable ROI
• Operates under this assumption:
More (relevant) traffic + Good Conversions Rate = More Sales/Leads
What is Search Engine Optimization?

searching a a means of increasing relevant traffic to a website
What is a SEO Algorithm?
• Top Secret! Only select employees of a search engines company
know for certain
• Reverse engineering, research and experiments gives SEOs (search
engine optimization professionals) a “pretty good” idea of the major
factors and approximate weight assignments
• The SEO algorithm is constantly changed, tweaked & updated
• Websites and documents being searched are also constantly changing
• Varies by Search Engine – some give more weight to on-page factors,
some to link popularity
