Inner links from the main page of the site show the most important sections of the site and serves as one of the most important factors of domain ranking as a whole.

  External links from the main page tie the site with other sites and determines the site's niche.

  The relation of external links to inner links influences the distribution of the site's weight in general. To grow the amount of indexed pages, there should be more inner links than external links.

  A great number of external links (or their quick growth) can be a sign that your site has been hacked and that links to SPAM resources have been added to the footer or hidden div elements in the HTML of your site.

  The amount of indexed pages first of all indicates the domain weight. Web masters must strive to make the number of indexed pages close to the actual number of pages.

  If the amount of indexed web pages exceeds the actual number, this can be due to duplicate content.

  In some cases, search engines consider duplicate content as cheating and manipulation....

  The amount of backward links points to the domain popularity on the Internet: the more links are given to this recourse, the more the resource is important and its traffic increases.

  Backward links are one of the external factors influencing the site's popularity and its location in the SERPs.

  In general, a valid HTML document is now very important for a webmaster. Search bots long ago have learned to correct and understand mistakes made by the webmaster, but a valid HTML document, in any case, has more chance of being correctly displayed in all browsers.

Although invalid documents may display OK in most current browsers, valid documents have a much better chance of being displayed correctly in browsers of the future.
