  • It's All About Visibility
    8 It’s All About Visibility This chapter looks at the critical tasks for getting your message found on the web. Now that we’ve discussed how to prepare a clear targeted message using the right words (Chapter 5, “The Audience Is Listening (What Will You Say?)”), we describe how online visibility depends on search engine optimization (SEO) “eat your broccoli” basics, such as lightweight and crawlable website code, targeted content with useful labels, and inlinks. In addition, you can raise the visibility of your website, products, and services online through online advertising such as paid search advertising, outreach through social websites, and display advertising. 178 Part II Building the Engine Who Sees What and How Two different tribes visit your website: people, and entities known as web spiders (or crawlers or robots). People will experience your website differently based on their own characteristics (their visual acuity or impairment), their browser (Internet Explorer, Chrome, Firefox, and so on), and the machine they’re using to view your website (a TV, a giant computer monitor, a laptop screen, or a mobile phone). Figure 8.1 shows a page on a website as it appears to website visitors through a browser. Figure 8.1 Screenshot of a story page on Model D, a web magazine about Detroit, Michigan, www.modeldmedia.com. What Search Engine Spiders See The web spiders are computer programs critical to your business because they help people who don’t know about your website through your marketing efforts find it through the search engines. The web spiders “crawl” through your website to learn about what it contains and carry information back to the gigantic servers behind the search engines, so that the search engine can provide relevant results to people searching for your product or service.

  • The Top 10 Ddos Attack Trends
    WHITE PAPER The Top 10 DDoS Attack Trends Discover the Latest DDoS Attacks and Their Implications Introduction The volume, size and sophistication of distributed denial of service (DDoS) attacks are increasing rapidly, which makes protecting against these threats an even bigger priority for all enterprises. In order to better prepare for DDoS attacks, it is important to understand how they work and examine some of the most widely-used tactics. What Are DDoS Attacks? A DDoS attack may sound complicated, but it is actually quite easy to understand. A common approach is to “swarm” a target server with thousands of communication requests originating from multiple machines. In this way the server is completely overwhelmed and cannot respond anymore to legitimate user requests. Another approach is to obstruct the network connections between users and the target server, thus blocking all communication between the two – much like clogging a pipe so that no water can flow through. Attacking machines are often geographically-distributed and use many different internet connections, thereby making it very difficult to control the attacks. This can have extremely negative consequences for businesses, especially those that rely heavily on its website; E-commerce or SaaS-based businesses come to mind. The Open Systems Interconnection (OSI) model defines seven conceptual layers in a communications network. DDoS attacks mainly exploit three of these layers: network (layer 3), transport (layer 4), and application (layer 7). Network (Layer 3/4) DDoS Attacks: The majority of DDoS attacks target the network and transport layers. Such attacks occur when the amount of data packets and other traffic overloads a network or server and consumes all of its available resources.

  • How Can I Get Deep App Screens Indexed for Google Search?
    HOW CAN I GET DEEP APP SCREENS INDEXED FOR GOOGLE SEARCH? Setting up app indexing for Android and iOS apps is pretty straightforward and well documented by Google. Conceptually, it is a three-part process: 1. Enable your app to handle deep links. 2. Add code to your corresponding Web pages that references deep links. 3. Optimize for private indexing. These steps can be taken out of order if the app is still in development, but the second step is crucial. Without it, your app will be set up with deep links but not set up for Google indexing, so the deep links will not show up in Google Search. NOTE: iOS app indexing is still in limited release with Google, so there is a special form submission and approval process even after you have added all the technical elements to your iOS app. That being said, the technical implementations take some time; by the time your company has finished, Google may have opened up indexing to all iOS apps, and this cumbersome approval process may be a thing of the past. Steps For Google Deep Link Indexing Step 1: Add Code To Your App That Establishes The Deep Links A. Pick A URL Scheme To Use When Referencing Deep Screens In Your App App URL schemes are simply a systematic way to reference the deep linked screens within an app, much like a Web URL references a specific page on a website. In iOS, developers are currently limited to using Custom URL Schemes, which are formatted in a way that is more natural for app design but different from Web.

(“Google”). Field contends that by allowing Internet users to access copies 4 of 51 of his copyrighted works stored by Google in an online repository, Google violated Field’s 5 exclusive rights to reproduce copies and distribute copies of those works. On December 19, 6 2005, the Court heard argument on the parties’ cross-motions for summary judgment. 7 Based upon the papers submitted by the parties and the arguments of counsel, the Court 8 finds that Google is entitled to judgment as a matter of law based on the undisputed facts. For 9 the reasons set forth below, the Court will grant Google’s motion for summary judgment: (1) that 10 it has not directly infringed the copyrighted works at issue; (2) that Google held an implied 11 license to reproduce and distribute copies of the copyrighted works at issue; (3) that Field is 12 estopped from asserting a copyright infringement claim against Google with respect to the works 13 at issue in this action; and (4) that Google’s use of the works is a fair use under 17 U.S.C.

  • Appendix I: Search Quality and Economies of Scale
    Appendix I: search quality and economies of scale Introduction 1. This appendix presents some detailed evidence concerning how general search engines compete on quality. It also examines network effects, scale economies and other barriers to search engines competing effectively on quality and other dimensions of competition. 2. This appendix draws on academic literature, submissions and internal documents from market participants. Comparing quality across search engines 3. As set out in Chapter 3, the main way that search engines compete for consumers is through various dimensions of quality, including relevance of results, privacy and trust, and social purpose or rewards.1 Of these dimensions, the relevance of search results is generally considered to be the most important. 4. In this section, we present consumer research and other evidence regarding how search engines compare on the quality and relevance of search results. Evidence on quality from consumer research 5. We reviewed a range of consumer research produced or commissioned by Google or Bing, to understand how consumers perceive the quality of these and other search engines. The following evidence concerns consumers’ overall quality judgements and preferences for particular search engines: 6. Google submitted the results of its Information Satisfaction tests. Google’s Information Satisfaction tests are quality comparisons that it carries out in the normal course of its business. In these tests, human raters score unbranded search results from mobile devices for a random set of queries from Google’s search logs. • Google submitted the results of 98 tests from the US between 2017 and 2020. Google outscored Bing in each test; the gap stood at 8.1 percentage points in the most recent test and 7.3 percentage points on average over the period.

  • Detection of Crawler Traps: Formalization and Implementation Defeating Protection on Internet and on the TOR Network
    Detection of Crawler Traps: Formalization and Implementation Defeating Protection on Internet and on the TOR Network Maxence Delong1, Baptiste David1 and Eric Filiol2;3 1Laboratoire de Virologie et de Cryptologie Operationnelles,´ ESIEA, Laval, France 2Department of Computing, ENSIBS, Vannes, France 3High School of Economics, Moscow, Federation of Russia [email protected], [email protected], efi[email protected] Keywords: Crawler Trap, Information Distance, Bots, TOR Network. Abstract: In the domain of web security, websites want to prevent themselves from data gathering performed by auto- matic programs called bots. In that way, crawler traps are an efficient brake against this kind of programs. By creating similar pages or random content dynamically, crawler traps give fake information to the bot and resulting by wasting time and resources. Nowadays, there is no available bots able to detect the presence of a crawler trap. Our aim was to find a generic solution to escape any type of crawler trap. Since the random generation is potentially endless, the only way to perform crawler trap detection is on the fly. Using machine learning, it is possible to compute the comparison between datasets of webpages extracted from regular web- sites from those generated by crawler traps. Since machine learning requires to use distances, we designed our system using information theory. We used wild used distances compared to a new one designed to take into account heterogeneous data. Indeed, two pages does not have necessary the same words and it is operationally impossible to know all possible words by advance. To solve our problematic, our new distance compares two webpages and the results showed that our distance is more accurate than other tested distances.
