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.
If you’ve seen ads appear at the top or right of search engines, then you already know what SEM is. When your ads display in these optimal, highly visible positions, your business can have an edge over your competition. Plus, most searchers only click on the first few results, which gives these premium ad spots a visual advantage to catch the attention of your future customers.

Here’s where the final lesson of composition comes in: continuity. Continuity is the process of combining shots into a sequence so that they appear to have happened at the same time and place. A key part of continuity is making sure any ancillary objects in the scene — for example, a cup of water on a desk — stay in the same place (and have the same amount of water) throughout all of the shots.


Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
How you mark up your images can impact not only the way that search engines perceive your page, but also how much search traffic from image search your site generates. An alt attribute is an HTML element that allows you to provide alternative information for an image if a user can’t view it. Your images may break over time (files get deleted, users have difficulty connecting to your site, etc.) so having a useful description of the image can be helpful from an overall usability perspective. This also gives you another opportunity – outside of your content – to help search engines understand what your page is about.

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]
