Web publishers often ask how they can maximize their visibility on the web. Much of this has to do with search engine optimization — making sure a publisher’s content shows up on all the search engines.
However, there are some cases in which publishers need to communicate more information to search engines — like the fact that they don’t want certain content to appear in search results. And for that they use something called the Robots Exclusion Protocol (REP), which lets publishers control how search engines access their site: whether it’s controlling the visibility of their content across their site (via robots.txt) or down to a much more granular level for individual pages (via META tags).
Since it was introduced in the early ’90s, REP has become the de facto standard by which web publishers specify which parts of their site they want public and which parts they want to keep private. Today, millions of publishers use REP as an easy and efficient way to communicate with search engines. Its strength lies in its flexibility to evolve in parallel with the web, its universal implementation across major search engines and all major robots, and in the way it works for any publisher, no matter how large or small.
You don’t have to be a mobile expert to see how smartphones are revolutionizing our daily lives. Lower prices, faster network speeds and unlimited data plans mean that people often reach for their cell phone rather than their computer when they are seeking information. As a result, mobile applications have become more and more popular, helping people find music, make restaurant reservations or check bank balances — all on their phone.
We want to contribute to the growth of these mobile applications, which is why we’re happy to announce our beta launch of AdSense for Mobile Applications. After all, advertisers are looking for ways to reach potential customers when they are engaged with mobile content, and application developers are looking for ways to show the best ads to their users. We have already had a successful trial of this service with a small number of partners, and are excited that we can now offer this solution to a broader group.
AdSense for Mobile Applications allows developers to earn revenue by displaying text and image ads in their iPhone and Android applications. For our beta launch, we’ve created a site where developers can learn more about the AdSense for Mobile Applications program, see answers to frequently asked questions and sign up to participate in our beta. Advertisers can also learn about the benefits of advertising in mobile applications.
We’re excited to open up this beta to more developers, and look forward to offering new features for our mobile advertisers and publishers in upcoming releases. We also want to say a big thank you to the partners who worked with us on the trial stages of this project including Backgrounds, Sega, Shazam, Urbanspoon and more.
Chances are good that at some point in your life you ran a search on an online search engine and instead of one hit you received pages and pages of possible hits. Have you ever wondered if the order the websites appear on search was just a random grouping or if they had been placed in a specific order that just appeared disorderly to you? The answer is that there is a very elaborate system used to determine where a website appears during an internet search. The process is something called search engine optimization.
Search engine optimization is the science and art of making web pages attractive to search engines.
Next time you run an internet search look at the bottom of the page. Chances are good that there will be a list of page numbers (normally written in blue) for you to click if you can’t find exactly what you are looking for on the first page. If you actually look farther then the second page you will part of a minority. Studies and research have shown that the average internet user does not look farther then the second page of potential hits. As you can imagine it’s very important to websites to be listed on the first two pages.
Some internet search engines are set up to look for keywords throughout a webpage, they then use a mathematical equation that takes in the amount of time the keywords appears on the webpage and factors it with the location of the keywords to determine the ranking of the webpage.
Search Engines are made up to look for keywords through a website or a webpage, they use a special kind of algorithm in order to rank a particular webpage.
Other internet search engines use a process that judges the amount of times a webpage is linked to other web pages to determine how a webpage is ranked. The process of using links to determine search engine ranking is called link analysis.
Keyword searches and link analysis are both part of a routine internet search engine procedure called search engine optimization. Search engine optimization is the art and science of making a website attractive to search engines, the more attractive a website appears to the search engine the higher it will rank in searches and in the world of internet searches ranking is everything.
PageRank is based on the link analyses algorithm. PageRank is described as a link analysis algorithm that assigns a numerical weight to each individual element of a hyperlink set of documents. The purpose is to measure its relative important with the set. The numerical weight assigned to any element is called PageRank of E. PR(E) is the denotation used.
PageRank operates on a system similar to a voting booth. Each time it finds a hyperlink to a webpage, PageRank counts that hyperlink as a vote that supports the webpage. People use many tricks to gain page rank to their websites. The more pages that link to the page, the more votes of support the webpage receives. If PageRank comes across a website that has absolutely no links connecting it to another webpage then it is not awarded any votes at all.
Tests done with a model like PageRank have shown that the system is not infallible.
The HITS algorithm is an alternate to the PageRank algorithm.
Google’s powers that be take a dim view on spamdexing. In 2005 Google designed and activated a program called nofollow, a program they designed to allow webmasters and bloggers to create links that PageRank would ingnore. The same system was also used to keep spamdexing to a minumum.
