SE indexing………

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

Page Ranking…… It is the way Google measures how popular a given

page is based on the number and quality of sites that link to it.

Page Rank was developed by Google founders Larry Page and Sergey Brin at Stanford. Page Rank is patented by Stanford, and the name Page Rank likely comes from Larry Page.

Page Rank is measured on a scale of one to ten and assigned to individual pages within a website, not the entire website.

What is SEO??????Search engine optimization (SEO) is the process

of affecting the visibility of a website or a web page in a search engine's "natural" or un-paid ("organic") search results.

Why SEO…..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

their products and servicesBuild their brand online by communicating

marketing messages to their target audienceIncrease their profile against their competitorsTarget a global audience via international search
