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.

Manipulative Linking Is An SEO Myth

One of the most popular forms of web spam, manipulative link acquisition relies on the search engines' use of link popularity in their ranking algorithms to attempt to artificially inflate these metrics and improve visibility. This is one of the most difficult forms of spamming for the search engines to overcome because it can come in so many forms. A few of the many ways manipulative links can appear include:

• Reciprocal link exchange programs, wherein sites create link pages that point back and forth to one another in an attempt to inflate link popularity. The engines are very good at spotting and devaluing these as they fit a very particular pattern.
• Link schemes, including "link farms" and "link networks" where fake or low value websites are built or maintained purely as link sources to artificially inflate popularity. The engines combat these through numerous methods of detecting connections between site registrations, link overlap or other common factors.
• Paid links, where those seeking to earn higher rankings buy links from sites and pages willing to place a link in exchange for funds. These sometimes evolve into larger networks of link buyers and sellers, and although the engines work hard to stop them (and Google in particular has taken dramatic actions), they persist in providing value to many buyers & sellers (see this post on paid links for more on that perspective).
• Low quality directory links are a frequent source of manipulation for many in the SEO field. A large number of pay-for-placement web directories exist to serve this market and pass themselves off as legitimate with varying degrees of success. Google often takes action against these sites by removing the PageRank score from the toolbar (or reducing it dramatically), but won't do this in all cases.

There are many more manipulative link building tactics that the search engines have identified and, in most cases, found algorithmic methods for reducing their impact. As new spam systems emerge, engineers will continue to fight them with targeted algorithms, human reviews and the collection of spam reports from webmasters & SEOs.

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.
