How SEO works?
Search engines work by crawling
hundreds of billions of pages with their own web crawlers. These web crawlers
are commonly called search engine bots or spiders. Search engines navigate the
Internet by downloading web pages, following links on those pages, and
discovering new pages as they become available.
Search Engine Index
Web pages found by search engines
are added to a data structure called an index.
· Keywords found in page content -
what topics does the page cover?
·
Type
of content crawled (using microdata called schema) - what does the page
contain?
·
Page
Freshness - How often has it been updated?
· Historical User Engagement for Pages
and Domains - How do people interact with pages?
What is the purpose of search engine
algorithms?
The main goal of a search engine
algorithm is to present a set of relevant high-quality search results that will
answer a user's query/question as quickly as possible.
The user then selects an option from
the list of search results, and this action, along with the next, then drives
future learning activities that can affect the engine's rankings future search.
What takes place while a search is
performed?
When a user enters a search query in
a search engine, all the pages that are relevant to the search query is indexed
and an algorithm is defined to set the order of the pages.
Search engines also uses other data
to return the results,
· Location - Some search queries
depend on location, for example, "nearby coffee shops" or "movie
times".
·
Detected
language - The search engine will return results in the user's language, if it
can be detected.
·
Past
Search History - Search engines will return different results for a query
depending on what the user searched for before
· Device – Depending upon the device a
different set of results for the search query
Why can't a page be indexed?
· Robots.txt file exclusion - a file
that tells the search engines what should be accessed and what should not be
accessed on your site.
·
Site
directives tell search engines not to index this page or to index another
similar page.
· Search engine algorithms consider
the page to be of low quality, have thin content, or contain duplicate content.
