Links - Links from other websites play a key role in determining the ranking of a site in Google and other search engines. The reason being, a link can be seen as a vote of quality from other websites, since website owners are unlikely to link to other sites which are of poor quality. Sites that acquire links from many other sites gain authority in the eyes of search engines, especially if the sites that are linking to them are themselves authoritative.
Social sharing and comments: If you’re on social media, you’re probably familiar with sharing and commenting. Social shares and comments are good indicators of how relevant your content is with your target audience. If a viewer watches your video and takes the time to share it with their network, you probably created a great piece of content. Social shares are also important because the more times your video is shared, the more it’ll be viewed. If your goal is to reach to reach a lot of people, social shares is good metric to track.

In February 2011, Google announced the Panda update, which penalizes websites containing content duplicated from other websites and sources. Historically websites have copied content from one another and benefited in search engine rankings by engaging in this practice. However Google implemented a new system which punishes sites whose content is not unique.[35] The 2012 Google Penguin attempted to penalize websites that used manipulative techniques to improve their rankings on the search engine.[36] Although Google Penguin has been presented as an algorithm aimed at fighting web spam, it really focuses on spammy links[37] by gauging the quality of the sites the links are coming from. The 2013 Google Hummingbird update featured an algorithm change designed to improve Google's natural language processing and semantic understanding of web pages. Hummingbird's language processing system falls under the newly recognised term of 'Conversational Search' where the system pays more attention to each word in the query in order to better match the pages to the meaning of the query rather than a few words [38]. With regards to the changes made to search engine optimization, for content publishers and writers, Hummingbird is intended to resolve issues by getting rid of irrelevant content and spam, allowing Google to produce high-quality content and rely on them to be 'trusted' authors.

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.

In the last 10 years, the digital landscape has changed significantly. People are phasing out desktop and laptop computers to search the web and interact with content. Instead, they are picking up their mobile phones and tablets. What’s more, digital technology is cheaper today than it’s ever been before; there are virtually no boundaries on how, when and where people can interact with content.
As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
