Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
The eigenvalue problem was suggested in 1976 by Gabriel Pinski and Francis Narin, who worked on scientometrics ranking scientific journals,[8] in 1977 by Thomas Saaty in his concept of Analytic Hierarchy Process which weighted alternative choices,[9] and in 1995 by Bradley Love and Steven Sloman as a cognitive model for concepts, the centrality algorithm.[10][11]

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?

DisabledGO, an information provider for people with disabilities in the UK and Ireland, hired Agency51 to implement an SEO migration strategy to move DisabledGO from an old platform to a new one. By applying 301 redirects to old URLS, transferring metadata, setting up Google webmaster tools, and creating a new sitemap, Agency 51 was able to successfully transfer DisabledGO to a new platform while keeping their previous SEO power alive. Additionally, they were able to boost visitor numbers by 21% year over year, and the site restructuring allowed DisabledGO to rank higher than competitors. Their case study is available on
An omni-channel approach not only benefits consumers but also benefits business bottom line: Research suggests that customers spend more than double when purchasing through an omni-channel retailer as opposed to a single-channel retailer, and are often more loyal. This could be due to the ease of purchase and the wider availability of products.[24]
But bear in mind that you can't guest post just anywhere and expect that it'll help. In fact, for years black hatters have perverted the value of guest posts by 'creating private blog networks,' which put out mass quantities of low-quality content for the sole purpose of exchanging backlinks. Google has caught on to this, and penalizes websites accordingly. So, you want to ensure that you only provide guest posts to reputable, respected websites that are relevant to your industry.
The search engine results page (SERP) is the actual result returned by a search engine in response to a keyword query. The SERP consists of a list of links to web pages with associated text snippets. The SERP rank of a web page refers to the placement of the corresponding link on the SERP, where higher placement means higher SERP rank. The SERP rank of a web page is a function not only of its PageRank, but of a relatively large and continuously adjusted set of factors (over 200).[35] Search engine optimization (SEO) is aimed at influencing the SERP rank for a website or a set of web pages.
Me, I didn’t like the sculpting idea from the start. I linked to what I thought should get links and figured that was pretty natural, to have navigational links, external links and so on — and natural has long been the think Google’s rewarded the most. So I didn’t sculpt, even after Matt helped put it out there, because it just made no long term sense to me.
Regarding nofollow on content that you don’t want indexed, you’re absolutely right that nofollow doesn’t prevent that, e.g. if someone else links to that content. In the case of the site that excluded user forums, quite a few high-quality pages on the site happened not to have links from other sites. In the case of my feed, it doesn’t matter much either way, but I chose not to throw any extra PageRank onto my feed url. The services that want to fetch my feed url (e.g. Google Reader or Bloglines) know how to find it just fine.
As mentioned earlier, technology and the internet allows for 24 hours a day, 7 days a week service for customers as well as enabling them to shop online at any hour of that day or night, not just when the shops are over and across the whole world. This is a huge advantage for retailers to use it and direct customers from the store to its online store. It has also opened up an opportunity for companies to only be online based rather than having an outlet or store due to the popularity and capabilities of digital marketing.
For instance, the Pew Internet & American Life Project has demographic data that suggests individuals between the ages of 18 and 33 are the most likely to use mobile Internet technology like smartphones and tablets, while the “Gen-X” demographic of individuals who are in their 30’s and 40’s are far more likely to seek out information through their laptop and desktop computers.(See also Targeted Marketing)
This will give you an indication of how many times a search is performed in a month (low numbers are not very useful unless there is a very clear buying signal in the keyphrase – working hard for five hits a month is not recommended in most cases) and how much the phrase is “worth” per click to advertisers (e.g., how much someone will pay to use that keyphrase). The more it’s worth, the more likely it is that the phrase is delivering business results for someone.
An entrepreneur or freelancer has two main strategies to tap into when marketing online. Search Engine Optimization (SEO), which attempts to rank your website on search engines “organically”, and Search Engine Marketing (SEM), which ranks your website in search results in exchange for money. Both strategies can be used to build a business succes...
PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. In fact the name. PageRank is a likely play on Larry Page's name. At the time that Page and Brin met, early search engines typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to attract higher search page results. Sometimes web designers would even put hidden text on pages to repeat phrases. 
For the most part, the 6-figure, 7-figure, and 8-figure-earners and up are making a large majority of their income by scaling out offers that they control. If you're just starting out, that avenue isn't for you. It only comes over time as you come to understand the field. As Sharpe says, most people first need to get a lay of the land and cruise through the virtual sales landscape before they dive into a massive undertaking like creating their own digital products and sales funnels.
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.
One final note is that if the links are not directly related to the subject, or you have no control over them, such as commentors’ website links, maybe you should consider putting them on another page, which links to your main content. That way you don’t leak page rank, and still gain hits from search results from the content of the comments. I may be missing something but this seems to mean that you can have your cake and eat it, and I don’t even think it is gaming the system or against the spirit of it. You might even gain a small sprinkling of page rank if the comment page accumulates any of it’s own.
One of the consequences of the PageRank algorithm and its further manipulation has been the situation when backlinks (as well as link-building) have been usually considered black-hat SEO. Thus, not only Google has been combating the consequences of its own child's tricks, but also mega-sites, like Wikipedia, The Next Web, Forbes, and many others who automatically nofollow all the outgoing links. It means fewer and fewer PageRank votes. What is then going to help search engines rank pages in terms of their safety and relevance?
There’s a lot of frustration being vented in this comments section. It is one thing to be opaque – which Google seems to be masterly at – but quite another to misdirect, which is what No Follow has turned out to be. All of us who produce content always put our readers first, but we also have to be sensible as far as on page SEO is concerned. All Google are doing with this kind of thing is to progressively direct webmasters towards optimizing for other, more reliable and transparent, ways of generating traffic (and no, that doesn’t necessarily mean Adwords, although that may be part of the intent).
Well, to make things worse, website owners quickly realized they could exploit this weakness by resorting to “keyword stuffing,” a practice that simply involved creating websites with massive lists of keywords and making money off of the ad revenue they generated. This made search engines largely worthless, and weakened the usefulness of the Internet as a whole. How could this problem be fixed?
I agree that the more facts that you provide and if you were to provide the complete algorithm, people would abuse it but if it were available to everyone, would it not almost force people to implement better site building and navigation policies and white hat seo simply because everyone would have the same tools to work with and an absolute standard to adhere to.

Google's strategy works well. By focusing on the links going to and from a Web page, the search engine can organize results in a useful way. While there are a few tricks webmasters can use to improve Google standings, the best way to get a top spot is to consistently provide top quality content, which gives other people the incentive to link back to their pages.
Thanks for sharing this, Matt. I’m happy that you took the time to do so considering that you don’t have to. What I mean is, in an ideal world, there should be no such thing as SEO. It is the SE’s job to bring the right users to the right sites and it is the job of webmasters to cater to the needs of the users brought into their sites by SEs. Webmasters should not be concerned of bringing the users in themselves. (aside from offsite or sponsored marketing campaigns) The moment they do, things start to get ugly because SEs would now have to implement counter-measures. (To most SEO tactics) This becomes an unending spiral. If people only stick to their part of the equation, SEs will have more time to develop algorithms for making sure webmasters get relevant users rather than to develop algorithms for combating SEOs to ensure search users get relevant results. Just do your best in providing valuable content and Google will try their best in matching you with your users. Don’t waste time trying to second guess how Google does it so that you can present yourself to Google as having a better value than you really have. They have great engineers and they have the code—you only have a guess. At most, the SEO anyone should be doing is to follow the webmasters guidelines. It will benefit all.
How does this all relate to disallows in the robots.txt? My ecom site has 12,661 pages disallowed because we got nailed for duplicate content. We sale batteries so revisons to each battery where coming up as duplicate content. Is PageRank being sent (and ignored) to these internal disallowed links as well? One of our category levels has hundreds of links to different series found under models, the majority of these series are disallowed. If PageRank acts the same with disallows as it does with nofollows, are these disallowed links are hurting our
Make sure your backlinks appear to be natural. Don’t ask webmasters to link back to your pages with a specific anchor text since this can haphazardly result in a pattern that may get noticed by search engines and cause you to get a linking penalty, a la Penguin. Also, don’t do anything shady or unnatural to create backlinks, like asking a site to put a link in the footer of every page on their site.
Disney initially stated they wouldn’t exceed one million in donations, but ended up donating two million after the campaign blew up. #ShareYourEars campaign garnered 420 million social media impressions, and increased Make-A-Wish’s social media reach by 330%. The campaign is a powerful example of using an internet marketing strategy for a good cause. #ShareYourEars raised brand awareness, cultivated a connected online community, and positively affected Disney’s brand image.

Marketing managers need to be conversant in every element of a marketing campaign, and considering the importance of an Internet presence in any marketing plan today, this means having a clear understanding of Internet marketing from start to finish. A marketing manager should have confidence in his or her team and know how to facilitate work efficiency and communication between coworkers. This keeps each project on schedule and helps create a relaxed work environment.
