85% of all traffic on the internet is referred from a search engine 90% of all users don’t look past the first 30 results (most only view top 10) Many websites aren’t even indexed, most are poorly optimized and get very little traffic from the search engines Cost-effective advertising Clear and measurable ROI Operates under this assumption: More (relevant) traffic + Good Conv. Rate = More Sales/Leads
What Search Engines Are the Most Popular? Figures below show what percentage of US internet users accessed the corresponding sites at least once during a given month. Counts only search-specific visits. (Nielsen//NetRatings – June 2004) Google – 41.6% Yahoo – 31.5% MSN – 27.4% AOL – 13.6% Ask Jeeves – 7.0%
Google feeds AOL, Netscape, Earthlink & others Yahoo owns Overture, AltaVista, All the Web, FAST & others Google, Yahoo & MSN results account for 80- 90% of all search traffic (rough estimate)
• Accumulate large index (database) of web documents to search• Provide highly-relevant results to users (better than competitors)• Generate revenue via paid advertising and related business ventures that typically leverage large amount of traffic
Spider “crawls” the web to find new documents (web pages, other documents) typically by following hyperlinks from websites already in the database Search engine indexes the content (text, code) in these documents by adding it to their huge databases and periodically updates this content Search engine searches its own database when user enters in a search to find related documents (not searching web pages in real-time) Search engine ranks resulting documents using an algorithm (mathematical formula) that assigns various weights to various ranking factors
Top Secret! Only select employees of the actual search engines know for certain Reverse engineering, research and experiments gives SEOs (search engine optimization professionals) a “pretty good” idea of major factors and approximate weight assignments Constantly changing, tweaking, updating is done to the algorithm 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
SEO = Search Engine Optimization Refers to the process of “optimizing” both the on-page and off-page ranking factors in order to achieve high search engine rankings for targeted search terms. Refers to the “industry” that revolves around obtaining high rankings in the search engines for desirable keyword search terms as a means of increasing the relevant traffic to a given website. Refers to an individual or company that optimizes websites for its clientele.

Reciprocal linking is common and generally accepted when not excessive and an attempt is made to provide value to the site visitor.• Google Bombing – establishing links with certain anchor text in order to achieve a high ranking for that term. Again, this becomes questionable when an attempt is made to misrepresent the website. (Miserable Failure example)
