What is A blog
weblog
is a discussion or informational website published on the World Wide Webconsisting of discrete, often informal diary-style text entries ("posts"). Posts are typically displayed in reverse chronological order, so that the most recent post appears first, at the top of the web page
Many blogs provide commentary on a particular subject or topic, ranging from politics to sports. Others function as more personal online diaries, and others function more as online brand advertising of a particular individual or company. A typical blog combines text, digital images, and links to other blogs, web pages, and other media related to its topic. The ability of readers to leave publicly viewable comments, and interact with other commenters, is an important contribution to the popularity of many blogs. However, blog owners or authors often moderate and filter online comments to remove hate speech or other offensive content. Most blogs are primarily textual, although some focus on art (art blogs), photographs (photoblogs), videos (video blogs or "vlogs"), music (MP3 blogs), and audio (podcasts). In education, blogs can be used as instructional resources. These blogs are referred to as edublogs. Microblogging is another type of blogging, featuring very short posts.
The collective community of all blogs and blog authors, particularly notable and widely read blogs, is known as the blogosphere. Since all blogs are on the internet by definition, they may be seen as interconnected and socially networked, through blogrolls, comments, linkbacks(refbacks, trackbacks or pingbacks), and backlinks. Discussions "in the blogosphere" are occasionally used by the media as a gauge of public opinion on various issues. Because new, untapped communities of bloggers and their readers can emerge in the space of a few years, Internet marketerspay close attention to "trends in the blogosphere
Blog search engines
Several blog search engines have been used to search blog contents, such as Bloglines, BlogScope, and Technorati. Technorati was one of the more popular blog search engines, but the website stopped indexing blogs and assigning authority scores in May 2014. The research community is working on going beyond simple keyword search, by inventing new ways to navigate through huge amounts of information present in the blogosphere, as demonstrated by projects like BlogScope,

A web banner or banner ad is a form of advertising on the World Wide Web delivered by an ad server. This form of online advertising entails embedding an advertisement into a web page. It is intended to attract traffic to a website by linking to the website of the advertiser. In many cases, banners are delivered by a central ad server. When the advertiser scans their logfiles and detects that a web user has visited the advertiser's site from the content site by clicking on the banner ad, the advertiser sends the content provider some small amount of money (usually around five to ten US cents).[citation needed] This payback system is often how the content provider is able to pay for the Internet access to supply the content in the first place. Usually though, advertisers use ad networks to serve their advertisements, resulting in a revshare system and higher quality ad placement.
Web banners function the same way as traditional advertisements are intended to function: notifying consumers of the product or service and presenting reasons why the consumer should choose the product in question, a fact first documented on HotWiredin 1996 by researchers Rex Briggs and Nigel Hollis.
Web banners differ in that the results for advertisement campaigns may be monitored real-time and may be targeted to the viewer's interests. Behavior is often tracked through the use of a click tag. Many web surfers regard these advertisements as annoying because they distract from a web page's actual content or waste bandwidth. In some cases, web banners cover screen content that the user wishes to see. Newer web browsers often include software "adblocker" options to disable pop-ups or block images from selected websites. Another way of avoiding banners is to use a proxy server that blocks them, such as Privoxy. Web browsers may also have extensions available that block banners, for example Adblock Plus for Mozilla Firefox, or AdThwart for Google Chrome and ie7pro for Internet Explorer.
