Outbound links are a drain on a site’s total PageRank. They leak PageRank. To counter the drain, try to ensure that the links are reciprocated. Because of the PageRank of the pages at each end of an external link, and the number of links out from those pages, reciprocal links can gain or lose PageRank. You need to take care when choosing where to exchange links.

Targeting, viewability, brand safety and invalid traffic: Targeting, viewability, brand safety and invalid traffic all are aspects used by marketers to help advocate digital advertising. Cookies are a form of digital advertising, which are tracking tools within desktop devices; causing difficulty, with shortcomings including deletion by web browsers, the inability to sort between multiple users of a device, inaccurate estimates for unique visitors, overstating reach, understanding frequency, problems with ad servers, which cannot distinguish between when cookies have been deleted and when consumers have not previously been exposed to an ad. Due to the inaccuracies influenced by cookies, demographics in the target market are low and vary (Whiteside, 2016).[42] Another element, which is affected within digital marketing, is ‘viewabilty’ or whether the ad was actually seen by the consumer. Many ads are not seen by a consumer and may never reach the right demographic segment. Brand safety is another issue of whether or not the ad was produced in the context of being unethical or having offensive content. Recognizing fraud when an ad is exposed is another challenge marketers face. This relates to invalid traffic as premium sites are more effective at detecting fraudulent traffic, although non-premium sites are more so the problem (Whiteside, 2016).[42]

To show an ad in PPC or Paid Search results, marketers create ads and then bid on specific search phrases for which to show them. These pay per click ads will then appear above and below the non-paid organic search results, and you’ll pay the search engine a small fee every time a user clicks on your ad, regardless of the total number of times the ad was shown.
There are two options for which ads are delivered: standard and accelerated. The standard delivery method shows ads evenly throughout the day. This option is good for advertisers who may have budget restrictions and want to ensure their ads show throughout the day. Depending on the budget concerns, ads will not show at all times. Accelerated delivery method shows ads until the budget is depleted. This option is best for advertisers who may not have budget restrictions and want to ensure their ads show for every query.
Write a description that would both inform and interest users if they saw your description meta tag as a snippet in a search result. While there's no minimal or maximal length for the text in a description meta tag, we recommend making sure that it's long enough to be fully shown in Search (note that users may see different sized snippets depending on how and where they search), and contains all the relevant information users would need to determine whether the page will be useful and relevant to them.
Guest Blogging: although this practice has been discredited due to the generation of poor quality articles, which have become spam (since they were used only to promote links), Google has failed to encourage this tactic. But, if you can ensure that you can create a high-quality guest post, that’s relevant to the context of your area, then go ahead.
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.[60] 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.[61] It is considered wise business practice for website operators to liberate themselves from dependence on search engine traffic.[62] In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
There’s obviously a huge number of reasons why a website might link to another and not all of them fit into the categories above. A good rule of thumb on whether a link is valuable is to consider the quality of referral traffic (visitors that might click on the link to visit your website). If the site won’t send any visitors, or the audience is completely unrelated and irrelevant, then it might not really be a link that’s worth pursuing.
To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain. Additionally, a page can be explicitly excluded from a search engine's database by using a meta tag specific to robots (usually ). When a search engine visits a site, the robots.txt located in the root directory is the first file crawled. The robots.txt file is then parsed and will instruct the robot as to which pages are not to be crawled. As a search engine crawler may keep a cached copy of this file, it may on occasion crawl pages a webmaster does not wish crawled. Pages typically prevented from being crawled include login specific pages such as shopping carts and user-specific content such as search results from internal searches. In March 2007, Google warned webmasters that they should prevent indexing of internal search results because those pages are considered search spam.[46]

This option is good for advertisers who may have budget restrictions and want to ensure their ads show throughout the day. Depending on the budget concerns, ads will not show at all times. Accelerated delivery method shows ads until the budget is depleted. This option is best for advertisers who may not have budget restrictions and want to ensure their ads show for every query.

Going back to our bicycle shop example: At this point, we’re ready to cancel our PPC account and never look back. But we dig a bit deeper, and notice that customers acquired from our PPC campaign spend another $800 each, per year, on higher-margin items that deliver an average profit of $200 per sale – we’re getting loyal, long-term business. That changes the picture significantly:
4. The facets of content marketing. Though content marketing can be treated as a distinct strategy, I see it as a necessary element of the SEO process. Only by developing high-quality content over time will you be able to optimize for your target keywords, build your site’s authority, and curate a loyal recurring audience. You should know the basics, at the very least, before proceeding with other components of SEO.
To answer your question, David, take a look at Jim’s comment below. Yes, you can and SHOULD optimize PR by directing link equity at important pages and internally linking within a theme. PageRank is a core part of the Google ranking algo. We don’t get visibility into PageRank as a number or score, but you need to know about the concept in order to direct your internal, strategic linking and navigation.
PageRank was once available for the verified site maintainers through the Google Webmaster Tools interface. However, on October 15, 2009, a Google employee confirmed that the company had removed PageRank from its Webmaster Tools section, saying that "We've been telling people for a long time that they shouldn't focus on PageRank so much. Many site owners seem to think it's the most important metric for them to track, which is simply not true."[65] In addition, The PageRank indicator is not available in Google's own Chrome browser.
The majority of web traffic is driven by the major commercial search engines, Google, Bing, and Yahoo!. Although social media and other types of traffic can generate visits to your website, search engines are the primary method of navigation for most Internet users. This is true whether your site provides content, services, products, information, or just about anything else.
Sometimes, you can find keyword ‘niches’ for which the top bid is a fantastic deal. These are longer, highly specific phrases, that not everyone will have taken the time to pursue; “long-tail search terms”. In this case, PPC is a great option because you can generate highly targeted traffic to your site for a fraction of the cost of any other form of paid advertising.
AdWords Customer Match lets you target customers based on an initial list of e-mail addresses. Upload your list and you do things like serving different ads or bidding a different amount based on a shopper’s lifecycle stage. Serve one ad to an existing customer. Serve another to a subscriber. And so on. Facebook offers a similar tool, but AdWords was the first appearance of e-mail-driven customer matching in pay per click search.
8. Technical SEO. Technical SEO is one of the most intimidating portions of the SEO knowledge base, but it’s an essential one. Don’t let the name scare you; the most technical elements of SEO can be learned even if you don’t have any programming or website development experience. For example, you can easily learn how to update and replace your site’s robots.txt file, and with the help of an online template, you should be able to put together your sitemap efficiently.

Content type: Many search features are tied to the topic of your page. For example, if the page has a recipe or a news article, or contains information about an event or a book. Google Search results can then apply content-specific features such as making your page eligible to appear in a top news stories carousel, a recipe carousel, or an events list.


All major crawler-based search engines leverage links from across of the web, but none of them report a static “importance” score in the way Google does via its Google Toolbar. That score, while a great resource for surfers, has also provided one of the few windows into how Google ranks web pages. Some webmasters, desperate to get inside Google, keep flying into that window like confused birds, smacking their heads and losing their orientation….
Most people who used the Google Toolbar probably never went through the effort of enabling the PageRank meter, which Google offered as an incentive to web surfers, a way for them to understand the quality of pages encountered when browsing (and a way for Google to understand what people were viewing beyond Google itself). But one group was very inclined to make the effort: SEOs.
So, digital marketing is about utilizing digital technology to achieve marketing objectives. There is no essential need for digital marketing to always be separate from the marketing department as a whole, as the objectives of both are the same. However, for now, it remains a useful term because digital marketing requires a certain skill set to utilize the digital technology effectively.

Although the full scope of SEO is far too broad to cover comprehensively here, all you need to know is that SEO focuses primarily on achieving higher rankings from an organic perspective. Businesses may hire an agency or SEO professional to perform their SEO work, but beyond this investment, no money changes hands and all the emphasis is placed on ranking more highly in organic search.
If you have the Google toolbar installed in your browser, you will be used to seeing each page’s PageRank as you browse the web. But all isn’t always as it seems. Many pages that Google displays the PageRank for haven’t been indexed in Google and certainly don’t have any PageRank in their own right. What is happening is that one or more pages on the site have been indexed and a PageRank has been calculated. The PageRank figure for the site’s pages that haven’t been indexed is allocated on the fly – just for your toolbar. The PageRank itself doesn’t exist.
Major search engines like Google, Yahoo!, and Bing primarily use content contained within the page and fallback to metadata tags of a web page to generate the content that makes up a search snippet.[9] Generally, the HTML title tag will be used as the title of the snippet while the most relevant or useful contents of the web page (description tag or page copy) will be used for the description.

Remember also, that search engine marketing is only one online digital communications tool. For established brands, we commonly see from web analytics that more than half of site visitors arrive at a site, not through search engines, but directly through typing in the web address or following a bookmark (web analytics tools label these as ‘no referrer'). The volume of direct visitors shows the power of branding, PR and offline communications in driving visitor traffic.
A decent article which encourages discussion and healthy debate. Reading some of the comments I see it also highlights some of the misunderstandings some people (including some SEOs) have of Google PageRank. Toolbar PageRank is not the same thing as PageRank. The little green bar (Toolbar PageRank) was never a very accurate metric and told you very little about the value of any particular web page. It may have been officially killed off earlier this year, but the truth is its been dead for many years. Real PageRank on the other hand, is at the core of Google’s algorithm and remains very important.
(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.
“Dangling links are simply links that point to any page with no outgoing links. They affect the model because it is not clear where their weight should be distributed, and there are a large number of them. Often these dangling links are simply pages that we have not downloaded yet……….Because dangling links do not affect the ranking of any other page directly, we simply remove them from the system until all the PageRanks are calculated. After all the PageRanks are calculated they can be added back in without affecting things significantly.”

For search engine optimization purposes, some companies offer to sell high PageRank links to webmasters.[38] As links from higher-PR pages are believed to be more valuable, they tend to be more expensive. It can be an effective and viable marketing strategy to buy link advertisements on content pages of quality and relevant sites to drive traffic and increase a webmaster's link popularity. However, Google has publicly warned webmasters that if they are or were discovered to be selling links for the purpose of conferring PageRank and reputation, their links will be devalued (ignored in the calculation of other pages' PageRanks). The practice of buying and selling links is intensely debated across the Webmaster community. Google advises webmasters to use the nofollow HTML attribute value on sponsored links. According to Matt Cutts, Google is concerned about webmasters who try to game the system, and thereby reduce the quality and relevance of Google search results.[38]
How many times do we need to repeat the calculation for big networks? That’s a difficult question; for a network as large as the World Wide Web it can be many millions of iterations! The “damping factor” is quite subtle. If it’s too high then it takes ages for the numbers to settle, if it’s too low then you get repeated over-shoot, both above and below the average - the numbers just swing about the average like a pendulum and never settle down.

The new digital era has enabled brands to selectively target their customers that may potentially be interested in their brand or based on previous browsing interests. Businesses can now use social media to select the age range, location, gender and interests of whom they would like their targeted post to be seen by. Furthermore, based on a customer's recent search history they can be ‘followed’ on the internet so they see advertisements from similar brands, products and services,[38] This allows businesses to target the specific customers that they know and feel will most benefit from their product or service, something that had limited capabilities up until the digital era.

Just a related note in passing: On October 6, 2013 Matt Cutts (Google’s head of search spam) said Google PageRank Toolbar won’t see an update before 2014. He also published this helpful video that talks more in depth about how he (and Google) define PageRank, and how your site’s internal linking structure (IE: Your siloing structure) can directly affect PageRank transfer. Here’s a link to the video: http://youtu.be/M7glS_ehpGY.

The majority of web traffic is driven by the major commercial search engines, Google, Bing, and Yahoo!. Although social media and other types of traffic can generate visits to your website, search engines are the primary method of navigation for most Internet users.
