How Search Engines Work - Video Blog

Search engines have two major functions - crawling & building an index, and providing answers by calculating relevancy & serving results.

Imagine the World Wide Web as a network of stops in a big city subway system.

Each stop is its own unique document (usually a web page, but sometimes a PDF, JPG or other file). The search engines need a way to “crawl” the entire city and find all the stops along the way, so they use the best path available – links.

1. Crawling and IndexingCrawling and indexing the billions of documents, pages, files, news, videos and media on the world wide web.
2. Providing Answers Providing answers to user queries, most frequently through lists of relevant pages, through retrieval and rankings.

“The link structure of the web serves to bind all of the pages together.”

Through links, search engines’ automated robots, called “crawlers,” or “spiders” can reach the many billions of interconnected documents.
Once the engines find these pages, they next decipher the code from them and store selected pieces in massive hard drives, to be recalled later when needed for a search query. To accomplish the monumental task of holding billions of pages that can be accessed in a fraction of a second, the search engines have constructed datacenters all over the world.
These monstrous storage facilities hold thousands of machines processing large quantities of information. After all, when a person performs a search at any of the major engines, they demand results instantaneously – even a 1 or 2 second delay can cause dissatisfaction, so the engines work hard to provide answers as fast as possible.

Search engines are answer machines. When a person looks for something online, it requires the search engines to scour their corpus of billions of documents and do two things – first, return only those results that are relevant or useful to the searcher’s query, and second, rank those results in order of perceived usefulness. It is both “relevance” and “importance” that the process of SEO is meant to influence.

To a search engine, relevance means more than simply finding a page with the right words. In the early days of the web, search engines didn’t go much further than this simplistic step, and their results suffered as a consequence. Thus, through evolution, smart engineers at the engines devised better ways to find valuable results that searchers would appreciate and enjoy. Today, 100s of factors influence relevance, many of which we’ll discuss throughout this guide.

How Do Search Engines Determine Importance?

Currently, the major engines typically interpret importance as popularity – the more popular a site, page or document, the more valuable the information contained therein must be. This assumption has proven fairly successful in practice, as the engines have continued to increase users’ satisfaction by using metrics that interpret popularity.

Popularity and relevance aren’t determined manually. Instead, the engines craft careful, mathematical equations – algorithms – to sort the wheat from the chaff and to then rank the wheat in order of tastiness (or however it is that farmers determine wheat’s value).

These algorithms are often comprised of hundreds of components. In the search marketing field, we often refer to them as “ranking factors” Moz crafted a resource specifically on this subject – Search Engine Ranking Factors.

Whether you're brand new to link building or have been doing it for a while, we're sure you'll find something useful in this guide. The landscape of SEO and link building is always changing, and today, the importance of building high-quality links has never been higher. The need to understand and implement high-quality campaigns is essential if you're going to compete and thrive online, and that isn't going to change any time soon. This guide is designed to get you going quickly and in the right direction. There is a lot to take in, but we've broken everything up into easy-to-digest chapters and have included lots of examples along the way. We hope you enjoy The Beginner's Guide to Link Building!

Definition of link building:

Link building is the process of acquiring hyperlinks from other websites to your own. A hyperlink (usually just called a link) is a way for users to navigate between pages on the internet. Search engines use links to crawl the web; they will crawl the links between the individual pages on your website, and they will crawl the links between entire websites. There are many techniques for building links, and while they vary in difficulty, SEOs tend to agree that link building is one of the hardest parts of their jobs. Many SEOs spend the majority of their time trying to do it well. For that reason, if you can master the art of building high-quality links, it can truly put you ahead of both other SEOs and your competition.

Why is link building important for SEO?

In order to understand the importance of link building, it's important to first understand the basics of how a link is created, how the search engines see links, and what they can interpret from them.

Why Does Your Company Need Social Media? - Social media

Whether you are running a small, local operation, or heading a global, enterprise-level effort, the statistics above make it clear: Your customers are online. They are interacting in social channels with their friends, colleagues, and other brands in search of information, recommendations, and entertainment. If your company is not around to answer, a competitor will be. In doing so, your competitor will quite likely take away the customer at hand, along with anyone else listening.

There are tons of opportunities to add value—even to delight!—and making that connection can help build a person's relationship with a company, brand, or representative. Those relationships create the foundation for what can eventually become one of your greatest marketing assets: customer advocacy.

Because so much of the customer experience now lives on the web, social media enables brands to take part in a customer's online experience outside of the typical channels.

If you ever find yourself in a bind, your advocates will help remind the rest of the world who they're rooting for. Advocacy is not something that you can stumble upon or buy. Advocacy is earned over time through continuous and positive engagement with your customer base. It is earned through experiences that delight, and through the delivery of the highest class of customer service.

Content Value Is An SEO Myth

Similar to how a page's value is judged against criteria such as uniqueness and the experience it provides to search visitors, so too does this principle apply to entire domains. Sites that primarily serve non-unique, non-valuable content may find themselves unable to rank, even if classic on and off page factors are performed acceptably. The engines simply don't want thousands of copies of Wikipedia or Amazon affiliate websites filling up their index, and thus use algorithmic and manual review methods to prevent this.

Search engines constantly evaluate the effectiveness of their own results. They measure when users click on a result, quickly hit the "back" button on their browser, and try another result. This indicates that the result they served didn't meet the user's query.

It's not enough just to rank for a query. Once you've earned your ranking, you have to prove it over and over again.

Trustworthiness Is An SEO Myth

Websites that earn trusted status are often treated differently from those who have not. In fact, many SEOs have commented on the "double standards" that exist for judging "big brand" and high importance sites vs. newer, independent sites. For the search engines, trust most likely has a lot to do with the links your domain has earned. Thus, if you publish low quality, duplicate content on your personal blog, then buy several links from spammy directories, you're likely to encounter considerable ranking problems. However, if you were to post that same content to a page on Wikipedia and get those same spammy links to point to that URL, it would likely still rank tremendously well - such is the power of domain trust & authority.

Trust built through links is also a great method for the engines to employ. A little duplicate content and a few suspicious links are far more likely to be overlooked if your site has earned hundreds of links from high quality, editorial sources like CNN.com or Cornell.edu. On the flip side, if you have yet to earn high quality links, judgments may be far stricter from an algorithmic view.

Low Value Pages Is An SEO Myth

Although it may not technically be considered "web spam," the engines all have methods to determine if a page provides unique content and "value" to its searchers before including it in their web indices and search results. The most commonly filtered types of pages are "thin" affiliate content, duplicate content, and dynamically generated content pages that provide very little unique text or value. The engines are against including these pages and use a variety of content and link analysis algorithms to filter out "low value" pages from appearing in the results.

Google's 2011 Panda update took the most aggressive steps ever seen in reducing low quality content across the web, and Google continues to update this process

Strategic Cloaking Is An SEO Myth

A basic tenet of all the search engine guidelines is to show the same content to the engine's crawlers that you'd show to an ordinary visitor. This means, among other things, not to hide text in the html code of your website that a normal visitor can't see.

When this guideline is broken, the engines call it "cloaking" and take action to prevent these pages from ranking in their results. Cloaking can be accomplished in any number of ways and for a variety of reasons, both positive and negative. In some cases, the engines may let practices that are technically "cloaking" pass, as they're done for positive user experience reasons. For more on the subject of cloaking and the levels of risk associated with various tactics and intents, see this post, White Hat Cloaking, from Rand Fishkin.

Search Engine Spam Is An SEO Myth

As long as there is search, there will always be spam. The practice of spamming the search engines - creating pages and schemes designed to artificially inflate rankings or abuse the ranking algorithms employed to sort content - has been rising since the mid-1990's.

With payouts so high (at one point, a fellow SEO noted to us that a single day ranking atop Google's search results for the query "buy viagra" could bring upwards of $20,000 in affiliate revenue), it's little wonder that manipulating the engines is such a popular activity on the web. However, it's become increasingly difficult and, in our opinion, less and less worthwhile for two reasons.

	1. Not Worth the Effort Users hate spam, and the search engines have a financial incentive to fight it. Many believe that Google's greatest product advantage over the last 10 years has been their ability to control and remove spam better than their competitors. It's undoubtedly something all the engines spend a great deal of time, effort and resources on. While spam still works on occasion, it generally takes more effort to succeed than producing "good" content, and the long term payoff is virtually non-existent. Instead of putting all that time and effort into something that the engines will throw away, why not invest in a value added, long term strategy instead? 2. Smarter Engines Search engines have done a remarkable job identifying scalable, intelligent methodologies for fighting spam manipulation, making it dramatically more difficult to adversely impact their intended algorithms. Complex concepts likeTrustRank (which Moz's Linkscape index leverages), HITS, statistical analysis, historical data and more have all driven down the value of search spam and made so-called "white hat" tactics (those that don't violate the search engines' guidelines) far more attractive. More recently, Google's Panda update introduced sophisticated machine learning algorithms to combat spam and low value pages at a scale never before witnessed online. If the search engines' job is to deliver quality results, they have raised the bar year after year. This guide is not intended to show off specific spam tactics, but, due to the large number of sites that get penalized, banned or flagged and seek help, we will cover the various factors the engines use to identify spam so as to help SEO practitioners avoid problems. For additional details about spam from the engines, see Google's Webmaster Guidelines and Bing's Webmaster FAQs (pdf). The important thing to remember is this: Not only do manipulative techniques not help you in most cases, but often times they cause search engines to impose penalties on your site. source: Moz.com

Paid Search Helps Boost Organic SEO Is An SEO Myth

Put on your tin foil hats, it's time for the most common SEO conspiracy theory: spending on search engine advertising (PPC) improves your organic SEO rankings.

In all of the experiences we've ever witnessed or heard about, this has never been proven nor has it ever been a probable explanation for effects in the organic results. Google, Yahoo! & Bing all have very effective walls in their organizations to prevent precisely this type of crossover.

At Google in particular, advertisers spending tens of millions of dollars each month have noted that even they cannot get special access or consideration from the search quality or web spam teams. So long as the existing barriers are in place and the search engines cultures maintain their separation, we believe that this will remain a myth. That said, we have seen anecdotal evidence that bidding on keywords you already organically rank for can help increase your organic click through rate.

Meta Tags and Keywords Are An SEO Myth

Once upon a time, much like search engine submission, meta tags (in particular, the meta keywords tag) were an important part of the SEO process. You would include the keywords you wanted your site to rank for and when users typed in those terms, your page could come up in a query. This process was quickly spammed to death, and eventually dropped by all the major engines as an important ranking signal.

It is true that other tags, namely the title tag (not stictly a meta tag, but often grouped with them) and meta description tag (coveredpreviously in this guide), are of critical importance to SEO best practices. Additionally, the meta robots tag is an important tool for controlling spider access. However, SEO is not "all about meta tags", at least, not anymore.

Search Engine Submission Is An SEO Myth

In classical SEO times (the late 1990's), search engines had "submission" forms that were part of the optimization process. Webmasters & site owners would tag their sites & pages with keyword information, and "submit" them to the engines. Soon after submission, a bot would crawl and include those resources in their index. Simple SEO!

Unfortunately, this process didn't scale very well, the submissions were often spam, and the practice eventually gave way to purely crawl-based engines. Since 2001, not only has search engine submission not been required, but it is actually virtually useless. The engines all publicly note that they rarely use "submission" URLs , and that the best practice is to earn links from other sites. This will expose your content to the engines naturally.

You can still sometimes find submission pages (here's one for Bing), but these are remnants of time long past, and are essentially useless to the practice of modern SEO. If you hear a pitch from an SEO offering "search engine submission" services, run, don't walk, to a real SEO. Even if the engines used the submission service to crawl your site, you'd be unlikely to earn enough "link juice" to be included in their indices or rank competitively for search queries.
