The PageRank formula also contains a damping factor (d) . According to the PageRank theory, there is an imaginary surfer who is randomly clicking on links, and at some point he gets bored and eventually stops clicking. The probability that the person will continue clicking at any step is a damping factor. Thus, this factor is introduced to stop some pages having too much influence. As a result, their total vote is damped down by multiplying it by 0.85 (a generally assumed value).
The criteria and metrics can be classified according to its type and time span. Regarding the type, we can either evaluate these campaigns "Quantitatively" or "Qualitatively". Quantitative metrics may include "Sales Volume" and "Revenue Increase/Decrease". While qualitative metrics may include the enhanced "Brand awareness, image and health" as well as the "relationship with the customers".
3. Have a discerning eye: learn from every landing page you visit. This applies to your casual surfing, online shopping, research and competitive analysis. After you’ve clicked on a paid ad, take a few extra seconds to observe the landing page and try to pick it apart. What works well on the landing page? What doesn’t? Take these observations and try to apply it to your site. It just might give you an edge over your competitors!
Interests are very similar to Topics. In fact, they are the same themes. However, the key difference is that Topics target websites and Interests target users. Google gleans user interest based on browsing history or self-selected interests if they’re logged in to their Google account. This allows your ads to appear on whatever site someone with your targeted interests is on, even if that site isn’t related.

## In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[21] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.

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.
3. General on-site optimization. On-site optimization is a collection of tactics, most of which are simple to implement, geared toward making your website more visible and indexable to search engines. These tactics include things like optimizing your titles and meta descriptions to include some of your target keywords, ensuring your site’s code is clean and minimal, and providing ample, relevant content on every page. I’ve got a huge list of on-site SEO tactics you can check out here.
Nathan: The comment by Mansi Rana helps answer your question. The fact is, the PageRank scores that were visible in the Google Toolbar hadn’t been updated in a long time (2+ YEARS), so they were probably getting more and more out-of-date anyway. The main reason Google would make them disappear, though, is that Google wants website owners to focus on the user and on quality content, not on trying to game the system with links.
Search Results: Ordered by relevance to your query, with the result that Google considers the most relevant listed first. Consequently you are likely to find what you’re seeking quickly by looking at the results in the order in which they appear. Google assesses relevance by considering over a hundred factors, including how many other pages link to the page, the positions of the search terms within the page, and the proximity of the search terms to one another.
And now it’s 2016. A time where an effective local business search campaign needs to include all of these tactics, not just one. Half-baked efforts won't work anymore. A deep dive into each individual marketing tactic will show you that what was enough to maintain a decent search presence in the past won't produce the same outcome and potential ROI today. Local business owners need to employ these tactics correctly from the beginning and invest the time and money to build their brand online in an effort to achieve what I call “The Ideal SERP.”
```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.

## Looking at the count of Impressions will provide you the total number of instances where keywords triggered ads to be shown on a search engine results page (SERP). When a search is performed in Google for the phrase “Hawaiian vacation with kids”, the following advertisers (1-3) each increased their impression count by one (+1) because of the search.

A lot goes into building a winning PPC campaign: from researching and selecting the right keywords, to organizing those keywords into well-organized campaigns and ad groups, to setting up PPC landing pages that are optimized for conversions. Search engines reward advertisers who can create relevant, intelligently targeted pay-per-click campaigns by charging them less for ad clicks. If your ads and landing pages are useful and satisfying to users, Google charges you less per click, leading to higher profits for your business. So if you want to start using PPC, it’s important to learn how to do it right.
Those engaging with your company online via mobile devices need to have the same positive experience as they would on desktop. This means implementing a mobile-friendly or responsive website design to make browsing user-friendly for those on mobile devices. It might also mean reducing the length of your lead generation forms to create a hassle-free experience for people downloading your content on-the-go. As for your social media images, it's important to always have a mobile user in mind when creating them as image dimensions are smaller on mobile devices, meaning text can be cut-off.
Pay-per-click is commonly associated with first-tier search engines (such as Google AdWords and Microsoft Bing Ads). With search engines, advertisers typically bid on keyword phrases relevant to their target market. In contrast, content sites commonly charge a fixed price per click rather than use a bidding system. PPC "display" advertisements, also known as "banner" ads, are shown on web sites with related content that have agreed to show ads and are typically not pay-per-click advertising. Social networks such as Facebook and Twitter have also adopted pay-per-click as one of their advertising models.

# 61. References and Sources: Citing references and sources, like research papers do, may be a sign of quality. The Google Quality Guidelines states that reviewers should keep an eye out for sources when looking at certain pages: “This is a topic where expertise and/or authoritative sources are important…”. However, Google has denied that they use external links as a ranking signal.

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.
Another disadvantage is that even an individual or small group of people can harm image of an established brand. For instance Dopplegnager is a term that is used to disapprove an image about a certain brand that is spread by anti-brand activists, bloggers, and opinion leaders. The word Doppelganger is a combination of two German words Doppel (double) and Ganger (walker), thus it means double walker or as in English it is said alter ego. Generally brand creates images for itself to emotionally appeal to their customers. However some would disagree with this image and make alterations to this image and present in funny or cynical way, hence distorting the brand image, hence creating a Doppelganger image, blog or content (Rindfleisch, 2016).
It helps to improve your ranking for certain keywords. If we want this article to rank for the term ’SEO basics’ then we can begin linking to it from other posts using variations of similar anchor text. This tells Google that this post is relevant to people searching for ‘SEO basics’. Some experts recommend varying your anchor text pointing to the same page as Google may see multiple identical uses as ‘suspicious’.

Students will learn how to utilize analytics in order to make data-driven decisions ranging from audience segmentation and targeting, to what content resonates best with users.
Junk traffic can also suck the life out of your campaign. Most, but not all pay per click services or providers distribute a segment of their budget to several search engines and other sites via their search partners and content networks. While you certainly want your ads displayed on Google and/or Bing, you may not want your ads showing up and generating clicks from some of the deeper, darker corners of the Internet. The resulting traffic may look fine in high-level statistics reports, but you have to separate out partner network campaigns and carefully manage them if you’re going to get your money’s worth.
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]
