Great article and writing in general. My company just published a 5,000 word Keyword targeting best practices guide for PPC and SEO, and we linked to your article “10 Reasons You Should Use Google Trends for More Than Just Keyword Research”. http://vabulous.com/keyword-research-targeting-for-ppc-and-seo-guide/ I would love if you checked it out and possibly shared it if you like it.
Description meta tags are important because Google might use them as snippets for your pages. Note that we say "might" because Google may choose to use a relevant section of your page's visible text if it does a good job of matching up with a user's query. Adding description meta tags to each of your pages is always a good practice in case Google cannot find a good selection of text to use in the snippet. The Webmaster Central Blog has informative posts on improving snippets with better description meta tags18 and better snippets for your users19. We also have a handy Help Center article on how to create good titles and snippets20.
Now, how much weight does PageRank carry? Like most every other part of the algorithm, it’s questionable. If we listed all the ranking factors, I don’t suspect it would be in the top 5, but it’s important to remember that the key to ranking well is to be the LESS IMPERFECT than your competition. IE: To have more of the right things that send the right signals in the right places so that Google sees you as a better, more relevant, candidate for the top three on page one. If you and your competitor both have optimized (on-page and technically) for the same keyword phrase perfectly, PR could be the deal breaker that pushes your blue link an inch up.
The problem is overcome by repeating the calculations many times. Each time produces slightly more accurate values. In fact, total accuracy can never be achieved because the calculations are always based on inaccurate values. 40 to 50 iterations are sufficient to reach a point where any further iterations wouldn’t produce enough of a change to the values to matter. This is precisiely what Google does at each update, and it’s the reason why the updates take so long.
For example, the search algorithm used by Google features hundreds of ranking factors, and while nobody outside of Google knows precisely what they are, some are thought to be more important than others. In the past, the link profile of a site – the number of external links that link to a specific website or web page from other websites – was an important ranking signal. It still is to some extent (which is why Wikipedia ranks so prominently in organic results for so many queries), though search advances at such a rapid pace that ranking signals that were once crucial to the search algorithm may be less important today, a source of constant frustration to SEOs.
Featured Snippet – Search results that appear at the top of the SERPs, just below the ads, are called Featured Snippets. Unlike other results, Featured Snippets highlight a significant portion of the content. That way, users can get the info they’re looking for without even clicking a link. That’s why Featured Snippets are sometimes called Answer Boxes. Marketers like it when their websites land in the Featured Snippet spot because Google users will often click the link to get a more detailed answer beyond what’s provided in the snippet.
If we look at these other definitions of digital marketing such as this definition of digital marketing from SAS: What is Digital Marketing and Why does it matter? or this alternative definition of digital marketing from Wikipedia we can see that often there is a focus on promoting of products and services using digital media rather than a more holistic definition covering customer experiences, relationship development and stressing the importance of multichannel integration. So for us, the scope of the term should include activities across the customer lifecycle:
As I was telling Norman above, these days what we’ve come to call content marketing is really a big part of “link building.” You can’t buy links, and “you link to me I’ll link to you” requests often land on deaf ears. Its really all about creating high quality content (videos, images, written blog posts) that appeals to the needs/wants of your target market, and then naturally earning inbound links from sources that truly find what you have to offer worth referencing.
(1 - d) - The (1 – d) bit at the beginning is a bit of probability math magic so the “sum of all web pages' PageRanks will be one”: it adds in the bit lost by the d(.... It also means that if a page has no links to it (no backlinks) even then it will still get a small PR of 0.15 (i.e. 1 – 0.85). (Aside: the Google paper says “the sum of all pages” but they mean the “the normalised sum” – otherwise known as “the average” to you and me.
9. Troubleshooting and adjustment. In your first few years as a search optimizer, you’ll almost certainly run into the same problems and challenges everyone else does; your rankings will plateau, you’ll find duplicate content on your site, and you’ll probably see significant ranking volatility. You’ll need to know how to diagnose and address these problems if you don’t want them to bring down the effectiveness of your campaign.
While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?
Unlike most offline marketing efforts, digital marketing allows marketers to see accurate results in real time. If you've ever put an advert in a newspaper, you'll know how difficult it is to estimate how many people actually flipped to that page and paid attention to your ad. There's no surefire way to know if that ad was responsible for any sales at all.
In 2005, in a pilot study in Pakistan, Structural Deep Democracy, SD2[59][60] was used for leadership selection in a sustainable agriculture group called Contact Youth. SD2 uses PageRank for the processing of the transitive proxy votes, with the additional constraints of mandating at least two initial proxies per voter, and all voters are proxy candidates. More complex variants can be built on top of SD2, such as adding specialist proxies and direct votes for specific issues, but SD2 as the underlying umbrella system, mandates that generalist proxies should always be used.
B2B Awareness: If you offer a service in which the sales cycle is measured in weeks and months instead of minutes, PPC can help with visibility and acquiring high-quality users. You can control the ad copy a new user sees and the content a new user is exposed to for a good first impression. You’re optimizing to pay for as many of the best clicks, and the best leads, at the lowest possible cost.
These are paid advertisements via Google AdWords. You can differentiate these from organic (non-paid, earned) results because of the tiny yellow “ad” icon. Normally, you will also see paid ads at the top of the SERP as well. In this book, we are only talking about SEO for organic search results, not advertising through search engines. But it is important to understand the difference as a user, and as a search engine optimizer, as they can both be valuable.

In 2007, Google announced a campaign against paid links that transfer PageRank.[29] On June 15, 2009, Google disclosed that they had taken measures to mitigate the effects of PageRank sculpting by use of the nofollow attribute on links. Matt Cutts, a well-known software engineer at Google, announced that Google Bot would no longer treat nofollowed links in the same way, to prevent SEO service providers from using nofollow for PageRank sculpting.[30] As a result of this change the usage of nofollow led to evaporation of PageRank. In order to avoid the above, SEO engineers developed alternative techniques that replace nofollowed tags with obfuscated Javascript and thus permit PageRank sculpting. Additionally several solutions have been suggested that include the usage of iframes, Flash and Javascript.[31]
