Search engine optimization (SEO) is often about making small modifications to parts of your website. When viewed individually, these changes might seem like incremental improvements, but when combined with other optimizations, they could have a noticeable impact on your site's user experience and performance in organic search results. You're likely already familiar with many of the topics in this guide, because they're essential ingredients for any web page, but you may not be making the most out of them.
The mathematics of PageRank are entirely general and apply to any graph or network in any domain. Thus, PageRank is now regularly used in bibliometrics, social and information network analysis, and for link prediction and recommendation. It's even used for systems analysis of road networks, as well as biology, chemistry, neuroscience, and physics.[43]
With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
The linking page’s PageRank is important, but so is the number of links going from that page. For instance, if you are the only link from a page that has a lowly PR2, you will receive an injection of 0.15 + 0.85(2/1) = 1.85 into your site, whereas a link from a PR8 page that has another 99 links from it will increase your site’s PageRank by 0.15 + 0.85(7/100) = 0.2095. Clearly, the PR2 link is much better – or is it? See here for a probable reason why this is not the case.
Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all dozens of aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.

PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by {\displaystyle PR(E).} Other factors like Author Rank can contribute to the importance of an entity.
The eigenvalue problem was suggested in 1976 by Gabriel Pinski and Francis Narin, who worked on scientometrics ranking scientific journals,[7] in 1977 by Thomas Saaty in his concept of Analytic Hierarchy Process which weighted alternative choices,[8] and in 1995 by Bradley Love and Steven Sloman as a cognitive model for concepts, the centrality algorithm.[9][10]

Search intent, accuracy, consumer confidence — if only search engines could read a person's mind when completing a search. Google can’t read your mind, but search engines can collectively measure and determine customer happiness with a local business by looking at that business’ reviews. If customers like a business’ products and services, then they regularly receive 4- and 5-star review, and the opposite is true for negative reviews. If your business has a poor overall rating, you need to work on fixing those issues because not only are those negative reviews harmful for bringing in new customers, they also signal to search engines your business isn’t a good choice for searchers.

From an SEO perspective, there is no difference between the best and worst content on the Internet if it is not linkable. If people can’t link to it, search engines will be very unlikely to rank it, and as a result the content won’t drive traffic to the given website. Unfortunately, this happens a lot more often than one might think. A few examples of this include: AJAX-powered image slide shows, content only accessible after logging in, and content that can't be reproduced or shared. Content that doesn't supply a demand or is not linkable is bad in the eyes of the search engines—and most likely some people, too.

Search engine advertising is one of the most popular forms of PPC. It allows advertisers to bid for ad placement in a search engine's sponsored links when someone searches on a keyword that is related to their business offering. For example, if we bid on the keyword “PPC software,” our ad might show up in the very top spot on the Google results page.
Everyone might be doing paid search, but very few do it well. The average Adwords click through rate is 1.91%, meaning that about only two clicks occur for every one hundred ad impressions. Don’t expect immediate success from your test but expect to walk away with education. The single most important goal in this first step is to find the formula of keywords, ads and user experience that works for your business.

Inclusion in Google's search results is free and easy; you don't even need to submit your site to Google. Google is a fully automated search engine that uses web crawlers to explore the web constantly, looking for sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when we crawl the web. Learn how Google discovers, crawls, and serves web pages.3
Keyword analysis. From nomination, further identify a targeted list of key­words and phrases. Review competitive lists and other pertinent industry sources. Use your preliminary list to determine an indicative number of recent search engine queries and how many websites are competing for each key­word. Prioritize keywords and phrases, plurals, singulars and misspellings. (If search users commonly misspell a keyword, you should identify and use it). Please note that Google will try to correct the term when searching, so use this with care.
The PageRank algorithm outputs a probability distribution used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for collections of documents of any size. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes, called “iterations”, through the collection to adjust approximate PageRank values to more closely reflect the theoretical true value.

Guest Blogging: although this practice has been discredited due to the generation of poor quality articles, which have become spam (since they were used only to promote links), Google has failed to encourage this tactic. But, if you can ensure that you can create a high-quality guest post, that’s relevant to the context of your area, then go ahead.
What is ​search engine optimization, then? It's not secrets or tricks — just ranking methodologies to follow in order to help a site that offers value to users beat the competition in search results. Today, you must be committed not just to optimizing your domain, but also to making it a quality site that attracts links naturally and is worthy of ranking.
In December 2009, Google announced it would be using the web search history of all its users in order to populate search results.[32] On June 8, 2010 a new web indexing system called Google Caffeine was announced. Designed to allow users to find news results, forum posts and other content much sooner after publishing than before, Google caffeine was a change to the way Google updated its index in order to make things show up quicker on Google than before. According to Carrie Grimes, the software engineer who announced Caffeine for Google, "Caffeine provides 50 percent fresher results for web searches than our last index..."[33] Google Instant, real-time-search, was introduced in late 2010 in an attempt to make search results more timely and relevant. Historically site administrators have spent months or even years optimizing a website to increase search rankings. With the growth in popularity of social media sites and blogs the leading engines made changes to their algorithms to allow fresh content to rank quickly within the search results.[34]
