Search Engines

• Google has been in the search industry since 1996.

• It uses more advanced techniques than other search engines when determining the quality of a link.

• One thing Google does look for is the natural link growth over a period of time.

• Google also places heavy emphasis on a Website being a source of information.

• Google operate aggressive duplicate content filters that filter out many pages with similar content.

• If a page is focused on a specific term, Google may filter the document out for that term.

• On page variation and link anchor text variation are also important factors Google look for.

• A page with a single reference or a different few references of a modifier will frequently outrank pages that are heavily focused on a search phrase containing that modifier.

• A 'spiders' crawl depth is determined not only by link quantity, but also link quality. Excessive low quality links may make your site less likely to be crawled deep or even included in the index
