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!
For some reason I had to delete some pages, these pages are using the HTML suffix, so I blocked them in robots.txt use Disallow: /*.html, but it’s been almost a year, I found that google robot often capture these pages, How can I quickly let Google completely remove these pages? And I have removed these URL from google webmaster tool by google index-> remove URLs, but Google still capture these pages.
Think about the words that a user might search for to find a piece of your content. Users who know a lot about the topic might use different keywords in their search queries than someone who is new to the topic. For example, a long-time football fan might search for [fifa], an acronym for the Fédération Internationale de Football Association, while a new fan might use a more general query like [football playoffs]. Anticipating these differences in search behavior and accounting for them while writing your content (using a good mix of keyword phrases) could produce positive results. Google Ads provides a handy Keyword Planner34 that helps you discover new keyword variations and see the approximate search volume for each keyword. Also, Google Search Console provides you with the top search queries your site appears for and the ones that led the most users to your site in the Performance Report35.
SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors.[61] Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day.[62] It is considered a wise business practice for website operators to liberate themselves from dependence on search engine traffic.[63] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
Btw, I was always under the impression that digg and delicious were dying but I’m really mistaken. Your(and Jason’s) thinking is foolproof though. If these guys are already curating content, there’s no reason they wouldn’t want to do more of just that! Seo has become a lot of chasing and pestering…it’s good of you to remind us that there are people out there just waiting to share stuff, too.:)

Social media. The algorithms have truly changed since social media first emerged. Many content websites are community-oriented -- Digg began allowing users to vote which stories make the front page, and YouTube factors views and user ratings into their front page rankings. Therefore, e-commerce stores must establish a strong social media presence on sites like Facebook , Pinterest, Twitter, etc. These social media sites send search engines signals of influence and authority.
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.
#16 is interesting because no one really knows about it. Myself and a former colleagu did a test on it about 4 years ago and published our results which conculded what you are saying. Since then I’ve been careful to follow this rule. The only issue is that often times using the exact kw does not “work” for navigation anchor texts. But with a little CSS trickery one can get the code for the nav bar to be lower in the code, prioritizing contextual links. I’ve also seen sites add links to 3-5 specific and important internal pages with keyword rich anchor texts, at the very top of the page in order to get those important internal links to be indexed first.
We expect advertisements to be visible. However, you should not let the advertisements distract users or prevent them from consuming the site content. For example, advertisements, supplement contents, or interstitial pages (pages displayed before or after the content you are expecting) that make it difficult to use the website.

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.
