The maximum PageRank in a site equals the number of pages in the site * 1. The maximum is increased by inbound links from other sites and decreased by outbound links to other sites. We are talking about the overall PageRank in the site and not the PageRank of any individual page. You don’t have to take my word for it. You can reach the same conclusion by using a pencil and paper and the equation.
An authority website is a site that is trusted by its users, the industry it operates in, other websites and search engines. Traditionally a link from an authority website is very valuable, as it’s seen as a vote of confidence. The more of these you have, and the higher quality content you produce, the more likely your own site will become an authority too.
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. The 2012 Google Penguin attempted to penalize websites that used manipulative techniques to improve their rankings on the search engine. Although Google Penguin has been presented as an algorithm aimed at fighting web spam, it really focuses on spammy links 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 . 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.
Optimization techniques are highly tuned to the dominant search engines in the target market. The search engines' market shares vary from market to market, as does competition. In 2003, Danny Sullivan stated that Google represented about 75% of all searches. In markets outside the United States, Google's share is often larger, and Google remains the dominant search engine worldwide as of 2007. As of 2006, Google had an 85–90% market share in Germany. While there were hundreds of SEO firms in the US at that time, there were only about five in Germany. As of June 2008, the marketshare of Google in the UK was close to 90% according to Hitwise. That market share is achieved in a number of countries.
I think Google will always be working to discern and deliver “quality, trustworthy” content and I think analyzing inbound links as endorsements is a solid tool the SE won’t be sunsetting anytime soon. Why would they? If the president of the United States links to your page that is undoubtedly an endorsement that tells Google you’re a legitimate trusted source. I know that is an extreme example, but I think it illustrates the principals of a linking-as-endorsement model well.
When running reports in the search engines you always have the option to further segment your data. You can segment by device, time, network, and much more . There are many different options to choose from giving you the granularity you desire. These can be located on many of the tabs in AdWords. Some segments will only apply to certain sub-sets of data, and other segments can be found once you download the report from the interface.
Exhaustive – Your keyword research should include not only the most popular and frequently searched terms in your niche, but also to the long tail of search. Long-tail keywords are more specific and less common, but they add up to account for the majority of search-driven traffic. In addition, they are less competitive, and therefore less expensive.
In 2012 Google was ruled to have engaged in misleading and deceptive conduct by the Australian Competition and Consumer Commission (ACCC) in possibly the first legal case of its kind. The Commission ruled unanimously that Google was responsible for the content of its sponsored AdWords ads that had shown links to a car sales website CarSales. The Ads had been shown by Google in response to a search for Honda Australia. The ACCC said the ads were deceptive, as they suggested CarSales was connected to the Honda company. The ruling was later overturned when Google appealed to the Australian High Court. Google was found not liable for the misleading advertisements run through AdWords despite the fact that the ads were served up by Google and created using the company’s tools.
Google recommends that all websites use https:// when possible. The hostname is where your website is hosted, commonly using the same domain name that you'd use for email. Google differentiates between the "www" and "non-www" version (for example, "www.example.com" or just "example.com"). When adding your website to Search Console, we recommend adding both http:// and https:// versions, as well as the "www" and "non-www" versions.
Consumer ratings are extra annotations that promote business ratings based on various customer surveys. This extension is only found in Google and is automatically populated. Google pulls these ratings from trusted sources and specifies that businesses must have at least 30 unique reviews in order to show. Consumer rating extensions are determined only for certain businesses and industries based on Google’s discretion.
Another excellent guide is Google’s “Search Engine Optimization Starter Guide.” This is a free PDF download that covers basic tips that Google provides to its own employees on how to get listed. You’ll find it here. Also well worth checking out is Moz’s “Beginner’s Guide To SEO,” which you’ll find here, and the SEO Success Pyramid from Small Business Search Marketing.
