  • Improvement of Content Relevancy – SEO’s focus is to improve the degree to which a website’s content matches a users need which, usually are represented through search engine queries or keywords.
  • Increasing Content Popularity – SEO also focus on increasing the popularity of website’s content on search engine listing.

SEO concepts involves achieving the goal as listed above of making web pages relevant and popular and for which understanding the search engine and knowledge of various technical terms involved is essential.

Search engine working

Search engines use an automated program called a “spider” or a “crawler” to roam the web and collect site data. A crawler records the text in web site and the location of the text in web site. It also follows the links in web site to the target pages of those links, where it starts the process over for the new page. The data collected by the crawler is then added to the database of the search engine, where it is indexed.

When a user initiates a search, the search engine queries its database for sites that contain the terms that the user has provided. Those sites are ranked according to the search engine’s algorithm, and then provided to the user in a results page.

When a search-engine spider crawls site, it collects text from the various web page elements like the <title> tag, the <meta name=”description”> tag, the <meta name=”keywords”> tag, the heading tags (<h1> through <h6>) and hyperlinks (<a> tags).

Crawlers will also collect paragraph text, although that text may not figure as prominently in the results page as the first five tag types.

Web sites can specify what pages and what links a crawler should not gather by using various site tools like Robots.txt, a file that lists the web pages that crawlers should ignore and a noindex attribute, which tells crawlers to ignore the page that contains the noindex attribute.

Different search engines use different content-ranking algorithms. Generally, the following factors determine how  page is ranked in the results page.

Search engines use the following factors to weight each instance of a search term:

  • Location – It refers to where a term appears in a page. If a specific search term is in the <title> tag of a page, search engines will generally assume that page is very relevant to the term.
  • Frequency – It refers to the number of times a term occurs in a page. If a specific search term appears more than once in a page, search engines will probably give a higher relevancy score.

By combining location and frequency factors, search engines can weight each instance of the search term to determine how relevant  page is. For example, a term may appear several times in a page but only in the body text. Because that term does not appear in the <title> tag or in any heading tags, a search engine may assume that the term is not the central focus of the page and may give less weight to those instances.

Authority – Authority refers to relevance granted by other sites. If  page has a high relevancy score for a term,  page ranking is higher if pages in other sites with high relevancy scores have links to  page. Authority is also granted by the users of search engines. The more people who select  site from results page of a search engine (often referred to as “click-throughs”), the higher the authority granted to  page by that search engine.
