How google search works ppt | backend & frontend part

  1. 1. How Google Search Engine Work ? By MM Rahman Bappi Independent SEO Consultant
  2. 2. There have 2 parts:  Backend Part  Crawling & Indexing (Via Google Webmaster Tools)  Algorithms (Users Search Behavior)  Fighting Spam (Flood Protection)  Frontend Part  Title (Keywords play the key role)  URL (Keywords play the key role)  Meta Description (Keywords play the key role)  Others
  3. 3. Backend Part Crawling & Indexing:  Find information by crawling  Crawler is called “Googlebot.”  Crawlers look at webpages and follow links on those pages.  They go from link to link and bring data about those webpages back to Google’s servers.  The crawl process begins with a list of web addresses from past crawls and sitemaps provided by website owners.  Crawlers pays special attention to new sites, changes to existing sites and dead links.  Organize information by indexing  Google index includes information about words and their locations.  When you search, at the most basic level, our algorithms look up your search terms in the index to find the appropriate pages.  When you search for “dogs” you don’t want a page with the word “dogs” on it hundreds of times.  You probably want pictures, videos or a list of breeds. ***Choice for website owners :- With the robots.txt file, site owners can choose not to be crawled by Googlebot, or they can provide more specific instructions about how to process pages on their sites.
  4. 4. Algorithms:-  Algorithms are the computer processes and formulas that take your questions and turn them into answers.  Today Google’s algorithms rely on more than 200 unique signals or “clues” that make it possible to guess what you might really be looking for.  These signals include things like the terms on websites, the freshness of content, your region and PageRank.
  5. 5. Fighting Spam:-  Spam sites attempt to game their way to the top of search results through techniques like repeating keywords over and over, buying links that pass PageRank or putting invisible text on the screen.  Google's algorithms can detect the vast majority of spam and demote it automatically. Types of Spam:-  Cloaking and/or sneaky redirects  Hacked site  Hidden text and/or keyword stuffing  Parked domains  Pure spam  Spammy free hosts and dynamic DNS providers  Thin content with little or no added value  Unnatural links from a site  Unnatural links to a site  User-generated spam
  6. 6. Frontend Part Title Tag:-  The title tag defines the title of your web page (or other web document), and is typically the text that appears as a blue link on search engine results pages.  Use powerful high CTR keywords & break your SERP.  Take the time to carefully craft your title tags.  Several of the words in the title match the user’s query — this causes them to be bolded in the SERPs.  Performance Tips:  As you develop your tags, focus on the following important elements: character length, word choice, and query match.  For increased organic clicks, try adjusting your page titles to be more relevant and/or enticing to click. But do not remove your target keywords as it could impact your organic ranking.
  7. 7. URL:-  The landing page in the example below leverages semantic markup for breadcrumb navigation. As a result, the display URL provides valuable context and additional clickable navigation options. Performance Tips:  When developing your URLs, pay attention to areas such as the folder structure, word choice, query match, and breadcrumb navigation snippets.  Ensure your site follows a well-organized folder structure and site hierarchy that leverages standard navigational tools such as breadcrumbs.  Be sure to mark up your pages with breadcrumb information for search engines.
  8. 8. Meta Description:-  Meta descriptions help users understand what your content is about before they see it.  Meta descriptions as free advertising  It’s basically an opportunity to get your message out each time your listing is displayed in the SERPs.  However, keep in mind that sometimes Google doesn’t display the meta description in a SERP snippet, and instead uses other sources like publically available data and/or the content of the page.
