2. Domain authority and page authority. Next, you should learn about domain authority and page authority, and how they predict your site’s search rankings. Here’s the basic idea; your site’s domain authority is a proprietary score, provided by Moz, of how “trustworthy” your domain is. It’s calculated based on the quantity and quality of inbound links to your website. The higher it is, the higher all your pages across your domain are likely to rank in organic search results. Page authority is very similar, but page-specific, and you can use it to engineer a link architecture that strategically favors some of your pages over others. Authority depends on the authority and volume of inbound links.
Think about the words that a user might search for to find a piece of your content. Users who know a lot about the topic might use different keywords in their search queries than someone who is new to the topic. For example, a long-time football fan might search for [fifa], an acronym for the Fédération Internationale de Football Association, while a new fan might use a more general query like [football playoffs]. Anticipating these differences in search behavior and accounting for them while writing your content (using a good mix of keyword phrases) could produce positive results. Google Ads provides a handy Keyword Planner34 that helps you discover new keyword variations and see the approximate search volume for each keyword. Also, Google Search Console provides you with the top search queries your site appears for and the ones that led the most users to your site in the Performance Report35.

Another way search engine marketing is managed is by contextual advertising. Here marketers place ads on other sites or portals that carry information relevant to their products so that the ads jump into the circle of vision of browsers who are seeking information from those sites. A successful SEM plan is the approach to capture the relationships amongst information searchers, businesses, and search engines. Search engines were not important to some industries in the past, but over the past years the use of search engines for accessing information has become vital to increase business opportunities.[31] The use of SEM strategic tools for businesses such as tourism can attract potential consumers to view their products, but it could also pose various challenges.[32] These challenges could be the competition that companies face amongst their industry and other sources of information that could draw the attention of online consumers.[31] To assist the combat of challenges, the main objective for businesses applying SEM is to improve and maintain their ranking as high as possible on SERPs so that they can gain visibility. Therefore, search engines are adjusting and developing algorithms and the shifting criteria by which web pages are ranked sequentially to combat against search engine misuse and spamming, and to supply the most relevant information to searchers.[31] This could enhance the relationship amongst information searchers, businesses, and search engines by understanding the strategies of marketing to attract business.

In March 2006, KinderStart filed a lawsuit against Google over search engine rankings. KinderStart's website was removed from Google's index prior to the lawsuit and the amount of traffic to the site dropped by 70%. On March 16, 2007 the United States District Court for the Northern District of California (San Jose Division) dismissed KinderStart's complaint without leave to amend, and partially granted Google's motion for Rule 11 sanctions against KinderStart's attorney, requiring him to pay part of Google's legal expenses.[68][69]
