2. What is SEO?
SEO is the act of modifying a website to increase its ranking in
organic (vs paid), crawler-based listings of search engines.
It is the art and science and magic of getting your website into
the major search engines and directories.
3. How does SEO work?
Most search engines use software programs called spiders (also
referred to as crawlers, robots, or bots). The spiders roam the
web to search the content and index them in their databases.
In search engine databases, Web pages are indexed on criteria
such as keyword occurrence and link popularity
Three types of search engines:
1. Crawler-based. Ex: Google. They use “spiders” to crawl the
Web
2. Human-Powered. Ex: Yahoo! Depends on human
submission
3. Hybrid. Ex: MSN Search. A combination of crawler and
human
4. What does SEO see?
Spiders do not see a page like humans do, as it cannot describe an
image, or tell you how pretty a site looks
Instead, it looks at the HTML code and structures to make sense. Using
a text browser, or disabling images and CSS are a good way of seeing
your site through a search engines eyes.
5. Techniques for SEO
White Hat: White hats tend to produce results that last a
long time, it conforms to the search engines' guidelines and
involves no deception.
Black hat : It attempts to improve rankings in ways that
are disapproved of by the search engines, or involve
deception.
Grey hat: This is in between black hat and white hat
approaches where the methods employed avoid the site
being penalized however do not act in producing the best
content for users, rather entirely focused on improving
search engine rankings.
