Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses hidden text, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.

Expertise and authoritativeness of a site increases its quality. Be sure that content on your site is created or edited by people with expertise in the topic. For example, providing expert or experienced sources can help users understand articles’ expertise. Representing well-established consensus in pages on scientific topics is a good practice if such consensus exists.
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.

It’s not enough to just share content through social channels – you need to actively participate in the community, too. Got a Twitter account? Then join in group discussions with relevant hashtags. Is your audience leaving comments on your Facebook posts? Answer questions and engage with your readers. Nothing turns people off quicker than using social media as a broadcast channel – use social media as it was intended and actually interact with your fans.
I love your post. I keep coming back because you always have great content I can use in my business as well as share. Since I own my own Digital Marketing company I guess you would be one of THE influencers in Internet Marketing field. I just started my business and because most influencers on twitter are talking about Content Marketing, that is what I have been writing about. But my site is only about a month old so I will just stay consistent in my writing. I’m also in the process of changing my navigation bar so be know how to get to what they want faster. Which would be “what is SEO”, etc. Thanks and would love any advice you can give me.
Not only are the tactics creative and unique, but you did an excellent job outlining each with step by step instructions, including great visuals, and providing concrete examples on how to implement the linking tactic. My favorite is probably the Flippa tactic. Amazing for pulling information on how other webmasters were able to acquire links, etc. Thanks again!
In December 2009, Google announced it would be using the web search history of all its users in order to populate search results.[33] 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..."[34] 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.[35]
While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
Page and Brin founded Google in 1998.[23] Google attracted a loyal following among the growing number of Internet users, who liked its simple design.[24] Off-page factors (such as PageRank and hyperlink analysis) were considered as well as on-page factors (such as keyword frequency, meta tags, headings, links and site structure) to enable Google to avoid the kind of manipulation seen in search engines that only considered on-page factors for their rankings. Although PageRank was more difficult to game, webmasters had already developed link building tools and schemes to influence the Inktomi search engine, and these methods proved similarly applicable to gaming PageRank. Many sites focused on exchanging, buying, and selling links, often on a massive scale. Some of these schemes, or link farms, involved the creation of thousands of sites for the sole purpose of link spamming.[25]
This information hits the mark. “If you want your content to go viral, write content that influencers in your niche will want to share.” I love the information about share triggers too. I’m wondering, though, if you could share your insights on how influencers manage to build such vast followings. At some point, they had to start without the support of other influencers. It would seem that they found a way to take their passion directly to a “ready” world. Excellent insights. Thanks for sharing.
