As of 2009, there are only a few large markets where Google is not the leading search engine. In most cases, when Google is not leading in a given market, it is lagging behind a local player. The most notable example markets are China, Japan, South Korea, Russia and the Czech Republic where respectively Baidu, Yahoo! Japan, Naver, Yandex and Seznam are market leaders.
For instance, you might use Facebook’s Lookalike Audiences to get your message in front of an audience similar to your core demographic. Or, you could pay a social media influencer to share images of your products to her already well-established community. Paid social media can attract new customers to your brand or product, but you’ll want to conduct market research and A/B testing before investing too much in one social media channel.
There are plenty of guides to marketing. From textbooks to online video tutorials, you can really take your pick. But, we felt that there was something missing — a guide that really starts at the beginning to equip already-intelligent professionals with a healthy balance of strategic and tactical advice. The Beginner’s Guide to Online Marketing closes that gap.
A backlink is a reference comparable to a citation. The quantity, quality, and relevance of backlinks for a web page are among the factors that search engines like Google evaluate in order to estimate how important the page is. PageRank calculates the score for each web page based on how all the web pages are connected among themselves, and is one of the variables that Google Search uses to determine how high a web page should go in search results. This weighting of backlinks is analogous to citation analysis of books, scholarly papers, and academic journals. A Topical PageRank has been researched and implemented as well, which gives more weight to backlinks coming from the page of a same topic as a target page. 
Matt, my biggest complaint with Google and this “page Rank” nofollow nightmare is it seems we need to have a certain type of site to get ranked well or to make your crawler happy, you say you want a quality site, but what my users deem as quality (3000 links to the best academic information on the planet for business development) is actually looked at by Google as a bad thing and I do not get any rank because of it, makes it hard for my site to be found, and people that can really use the information can not find it when you yourself would look at the info and think it was fantastic to find it all in one place.
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.
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.
Social media is a mixed bag when it comes to backlinks. There is a modicum of value, as social media sites allow you to link to your website in your profile. However, these days Facebook, Twitter, and other social media sites mark links as 'nofollow,' meaning that they don't pass SEO value (sometimes referred to as "link juice") to the linked site. These links won't do anything to boost your site's performance in search results.
Assume a small universe of four web pages: A, B, C and D. Links from a page to itself are ignored. Multiple outbound links from one page to another page are treated as a single link. PageRank is initialized to the same value for all pages. In the original form of PageRank, the sum of PageRank over all pages was the total number of pages on the web at that time, so each page in this example would have an initial value of 1. However, later versions of PageRank, and the remainder of this section, assume a probability distribution between 0 and 1. Hence the initial value for each page in this example is 0.25.
There are a few things to consider when beginning your backlink building campaign. It is helpful to keep track of your backlinks, to know which sites are linking back to you, and how the anchor text of the backlink incorporates keywords relating to your site. A tool to help you keep track of your backlinks is the Domain Stats Tool. This tool displays the backlinks of a domain in Google, Yahoo, and MSN. It will also tell you a few other details about your website, like your listings in the Open Directory, or DMOZ, from which Google regards backlinks highly important; Alexa traffic rank, and how many pages from your site that have been indexed, to name just a few.
One thing is certain: interlinking sites doesn't help you from a search engine standpoint. The only reason you may want to interlink your sites in the first place might be to provide your visitors with extra resources to visit. In this case, it would probably be okay to provide visitors with a link to another of your websites, but try to keep many instances of linking to the same IP address to a bare minimum. One or two links on a page here and there probably won't hurt you.
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 successfully—but which one is right for you?
Wikipedia, naturally, has an entry about PageRank with more resources you might be interested in. It also covers how some sites using redirection can fake a higher PageRank score than they really have. And since we’re getting all technical — PageRank really isn’t an actual 0 to 10 scale, not behind the scenes. Internal scores are greatly simplified to match up to that system used for visible reporting.
What I like the most about Monitor Backlinks is that we can keep track of every single link, and that we can see the status of those links when they change or become obsolete. The details and the whole overview of Monitor Backlinks, is exactly what I need and no more, because there are a lot of SEO programmes on the market today, which promise to do what's necessary, but don't. Monitor Backlinks is exactly what I need for my SEO, and no more than that needed.
Matt Cutts, it’s Shawn Hill from Longview, Texas and I’ve got to say, “you’re a semseo guru”. That’s obviously why Google retained you as they did. Very informative post! As head of Google’s Webspam team how to you intend to combat Social Networking Spam (SNS)? It’s becoming an increasingly obvious problem in SERPs. I’m thinking Blogspam should be the least of Google’s worries. What’s your take?
