Math is Your Friend + We've Got the Winning Formula
PageRank (PR) is an algorithm used by Google Search to rank websites in their search engine results. PageRank was named after Larry Page, one of the founders of Google. PageRank is a way of measuring the importance of website pages. According to Google, PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites. It is not the only algorithm used by Google to order search engine results, but it is the first algorithm that was used by the company, and it is the best-known.
A PageRank results from a mathematical algorithm based on the webgraph, created by all World Wide Web pages as nodes and hyperlinks as edges, taking into consideration authority hubs such as cnn.com or usa.gov. The rank value indicates an importance of a particular page. A hyperlink to a page counts as a vote of support. The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it ("incoming links"). A page that is linked to by many pages with high PageRank receives a high rank itself.
FIG 1a. Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. If web surfers who start on a random page have an 85% likelihood of choosing a random link from the page they are currently visiting, and a 15% likelihood of jumping to a page chosen at random from the entire web, they will reach Page E 8.1% of the time. (The 15% likelihood of jumping to an arbitrary page corresponds to a damping factor of 85%.) Without damping, all web surfers would eventually end up on Pages A, B, or C, and all other pages would have PageRank zero. In the presence of damping, Page A effectively links to all pages in the web, even though it has no outgoing links of its own.
A Web crawler may use PageRank as one of a number of importance metrics it uses to determine which URL to visit during a crawl of the web. One of the early working papers that were used in the creation of Google is "efficient crawling through URL ordering," which discusses the use of a number of different importance metrics to determine how deeply, and how much of a site Google will crawl. PageRank is presented as one of a number of these importance metrics, though there are others listed such as the number of inbound and outbound links for a URL, and the distance from the root directory on a site to the URL.
Links + Content
Tell Your Story to the World
Google elaborated on the reasons for PageRank deprecation at Q&A #March and announced Links and Content as the Top Ranking Factors. RankBrain was announced as the #3 Ranking Factor in October 2015, so the Top 3 Factors, including PageRank, are now confirmed officially by Google. Importantly, Links and Content are the top ranking factor, and this is an area in which we excel and where we focus most of our attention when building your website.
Simply stated, Links and Content are just what they say. Strategically crafted keywords and links must be included throughout your website, in an effort to increase keyword frequency and ranking factors. Inbound links and outbound links are a part of every successful SEO campaign. And of course Content is king on the web, and there are no shortcuts or magic formulas at work here. Just good, old-fashioned text on a page, well-written and crafted in a way to appeal to both website visitors and search engine spiders as well. Nothing else matters if your website does not have high-quality, timely and relevant content. Creating that content and making it relevent and compelling is what we do best.
Artificial Intelligence That's Pure Genius
RankBrain is an algorithm learning artificial intelligence system, the use of which was confirmed by Google on 26 October 2015. It helps Google to process search results and provide more relevant search results for users. In a 2015 interview, Google commented that RankBrain was the third most important factor in the ranking algorithm along with Links and Content. As of 2015, "RankBrain was used for less than 15% of queries." The results show that RankBrain produces results that are well within 10% of the Google search engine engineer team.
If RankBrain sees a word or phrase it isn't familiar with, the machine can make a guess as to what words or phrases might have a similar meaning and filter the result accordingly, making it more effective at handling never-before-seen search queries or keywords. Search queries are sorted into word vectors, also known as "distributed representations," which are close to each other in terms of linguistic similarity. RankBrain attempts to map this query into words (entities) or clusters of words that have the best chance of matching it. Therefore, RankBrain attempts to guess what people mean and records the results, which adapts the results to provide better user satisfaction.
There are over 200 different ranking factors which make up the ranking algorithm, whose exact functions in the Google algorithm are not fully disclosed. Behind Links and Content, RankBrain is considered the third most important signal in determining ranking on Google search. Although Google has not admitted to any order of importance, only that Rankbrain is one of the three most important of its search ranking signals. When offline, RankBrain is given batches of past searches and learns by matching search results. Studies showed how RankBrain better interpreted the relationships between words. This can include the use of stop words in a search query ("the," "and," without," etc) – words that were historically ignored previously by Google but are sometimes of a major importance to fully understanding the meaning or intent behind a person's search query. It's also able to parse patterns between searches that are seemingly unconnected, to understand how those searches are similar to each other. Once RankBrain's results are verified by Google's team the system is updated and goes live again.
Don't Stop 'Til You Reach the Top
The Search Engine Results Page (SERP) is the actual result returned by a search engine in response to a keyword query. The SERP consists of a list of links to web pages with associated text snippets. The SERP rank of a web page refers to the placement of the corresponding link on the SERP, where higher placement means higher SERP rank. The SERP rank of a web page is a function not only of its PageRank, but of a relatively large and continuously adjusted set of factors (over 200). Search engine optimization (SEO) is aimed at influencing the SERP rank for a website or a set of web pages.
Positioning of a webpage on Google SERPs for a keyword depends on relevance and reputation, also known as authority and popularity. PageRank is Google's indication of its assessment of the reputation of a webpage: It is non-keyword specific. Google uses a combination of webpage and website authority to determine the overall authority of a webpage competing for a keyword. The PageRank of the Home Page of a website is the best indication Google offers for website authority.
After the introduction of Google Places into the mainstream organic SERP, numerous other factors in addition to PageRank affect ranking a business in Local Business Results.
