Bloggers Glossary part 2
Categories: Most blogs cover a wide range of sub-topics, and those are called categories. A technology blog, for instance, might have different categories for software, hardware and science news.
Comments: Virtually all blog platforms contain a comment system where readers are able to comment and leave feedback on each page and/or post of the blog. The author might or might not require user registration before a comment can be posted. This feature transformed blogs into live conversations, and it contributed largely to their overall success on the Internet.
Comment spam: Comments made with the sole purpose of gaining a backlink, which in turn will send traffic or link juice (provided the blog in question doesn’t use the nofollow tag) to the site of the spammer. Some spam comments are very explicit and come with several links to drug or gambling related sites. Other forms are more subtle, where the commenter actually tries to leave a relevant message on the blog.
Compete: A web analytics company that, like Alexa, tracks and estimates the traffic levels of websites. They have a particular bias towards the U.S. market.
CPC: Acronym for Cost-per-Click, and it represents a form of online advertising where advertisers bid an amount of money that they are willing to spend for every visitor that clicks on his ad and visits his website or product page. On the other side you have publishers that choose to display CPC ads on their sides, and they earn money for every click. The most popular CPC ad network on the Internet is Google AdWords-AdSense, and CPC rates can vary from $0.01 up to $50 in some rare cases.
CPA: Acronym for Cost-per-Action, and it represents a form of online advertising where advertisers pay when visitors perform a specific action (e.g., when they sign up for an email newsletter or when they end up purchasing the product). Most affiliate marketing programs tend to use a CPA scheme.
CPM: Acronym for Cost-per-Mille, where mille means 1000 in Latin. CPM, therefore, is the cost per 1000 page impressions, and it represents a form of online advertising where advertisers will pay a fixed price for getting their banners or ads displayed 1000 times on a specific website.
CSS: Acronym for Cascading Style Sheets, and it is a language used to style web pages written in HTML and XHTML. The advantage of CSS is that it allows you to control the style of any number of pages simultaneously from a central location (the CSS file).
Digg: The original and most popular social bookmarking site. It is a basically a user-driven site, where the members of the community get to decide (by voting or burying the stories) what should go to the front page and what should not. For most web publishers, getting featured on Digg is a joy. It can send tens of thousands of visitors in a single day. There is some controversy around the quality of this traffic though, due to the peculiar traits of Digg users. For example, it is reported that those visitors don’t stick on the website for long, and they rarely click on ads.
Digg Auto-Bury: It has never been officially confirmed by Digg, but there is strong evidence to suggest that they have a penalty that makes it impossible for the penalized website to reach the front page, regardless of how many votes its stories might receive. Websites and blogs receive the auto-bury penalty when users report them for spam or for not submitting original content repeatedly.
Digg Bury-Brigade: A group (or groups) or active and loyal Digg users that try to keep the site free from what they consider to be spam or low quality content. The make this control by mass burying stories. Certain topics tend to get targeted often by those groups, including blogging, online marketing and search engine optimization.
Domain: Also known as domain name or hostname, it is a name that identifies a website or computer on the Internet. An example of a domain is yahoo.com. Notice that http://www.yahoo.com is no longer the domain but rather an URL.
Duplicate content: The presence of very similar content (usually text) inside a website or across different websites. Search engines tend to penalize websites that contain a large amount of duplicate content.
