SEO Fundamentals

There are multiple points you will come across while doing the SEO such as –

  • Index – Google stores all web pages that it knows about in its index. The index entry for each page describes the content and location (URL) of that page. To index is when Google fetches a page, reads it and adds it to the index: Google indexed several pages on my site today.
  • Crawl – The process of looking for new or updated web pages. Google discovers URLs by following links, by reading sitemaps, and by many other means. Google crawls the web, looking for new pages, then indexes them (when appropriate).
  • Crawler – Automated software that crawls (fetches) pages from the web and indexes them.
  • Googlebot – The generic name of Google’s crawler. Googlebot crawls the web constantly.
  • SEO – Search engine optimization: the process of making your site better for search engines. 

It is important to understand how Google search works.

Google does this in 3 stages:

  1. Crawling – The first stage is finding out what pages exist on the web.
  2. Indexing – After a page is crawled, Google tries to understand what the page is about. Once confirmed that the page is original and doesn’t have any errors it stores it in an indexing database.
  3. Serving search results – When a user enters a query, our machines search the index for matching pages and return the results Google believes are the highest quality and most relevant to the user’s query.

Overall, Google makes use of a mechanism called crawling and indexing in which website owners can provide page titles, content, or description and image with some other meta information for Google to store information in an organized way so that Google can identify which information can be shown for which search terms.
