As I had a teacher at school who was always really picky on how to draw conclusions I must say that the conclusions you drew for your health situation might be true, but dangerous. For example: If slightly more women than men suffer from health deseases it could be wise to write the information toward women. But, if you take search behaviour into account thing could look a lot different: It might turn up that men search more than women or that (senior) men are more present on the net than women.
Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.
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.
In addition, you can also use tools like Majestic SEO to see who is linking to your competitors. Once you identify the links to your competitor’s sites, you can analyze these links, learn how they got them and implement a similar strategy for your website. For example, did they donate to a charity causing the charity to link to their site? You can do the same thing.
By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation. To provide better results to their users, search engines had to adapt to ensure their results pages showed the most relevant search results, rather than unrelated pages stuffed with numerous keywords by unscrupulous webmasters. This meant moving away from heavy reliance on term density to a more holistic process for scoring semantic signals. Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, poor quality or irrelevant search results could lead users to find other search sources. Search engines responded by developing more complex ranking algorithms, taking into account additional factors that were more difficult for webmasters to manipulate. In 2005, an annual conference, AIRWeb (Adversarial Information Retrieval on the Web), was created to bring together practitioners and researchers concerned with search engine optimization and related topics.
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.:)
I have been trying to produce more content because I believed the lack of traffic was to the small amount of content, but after reading your blog post, i’m beginning to doubt wether or not this is quality content. I will definitely do more research on influencers on my niche, now I have to figure out how to get their attention with my kind of content.
For example, if a swimming pool business is trying to rank for "fiberglass pools" -- which is receiving 110,000 searches per month -- this short-tail keyword can be the one that represents the overarching topic on which they want to create content. The business would then identify a series of long-tail keywords that relate to this short-tail keyword, have reasonable monthly search volume, and help to elaborate on the topic of fiberglass pools. We'll talk more about these long-tails in the next step of this process.
Great post. I know most of the stuff experienced people read and think “I know that already”… but actually lots of things we tend to forget even though we know them. So its always good to read those. What I liked most was the broken link solution. Not only to create a substitute for the broken link but actually going beyond that. I know some people do this as SEO technique but its actually also useful for the internet as you repair those broken links that others find somewhere else.
