A video blog or video log, sometimes shortened to vlog (pronounced
'vlog' or 'v-log') is a form of blog for which the medium is video, and is a
form of web television. Vlog entries often combine embedded video (or a
video link) with supporting text, images, and other metadata. Entries can be
recorded in one take or cut into multiple parts. The vlog category is popular
Video logs (vlogs) also often take advantage of web syndication to allow
for the distribution of video over the Internet using either
the RSS or Atom syndication formats, for automatic aggregation and
playback on mobile devices and personal computers (See video podcast).
Miscellaneous video blogging events

An MP3 blog is a type of blog in which the creator makes music files,
normally in the MP3 format, available for download. They are also known
as musicblogs, audioblogs or soundblogs (the latter two can also
mean podcasts). MP3 blogs have become increasingly popular since
2003. The music posted ranges from hard-to-find rarities that have not
been issued in many years to more contemporary offerings, and
selections are often restricted to a particular musical genre or theme.
Some musicblogs offer music in Advanced Audio Coding (AAC)
or Ogg formats.
A web directory or link directory is a directory on the World Wide Web. It
specializes in linking to other web sites and categorizing those links.
A web directory is not a search engine and does not display lists of web pages
based on keywords; instead, it lists web sites by category and
subcategory. Most web directory entries are also not found by web
crawlers but by humans. The categorization is usually based on the whole web
site rather than one page or a set of keywords, and sites are often limited to
inclusion in only a few categories. Web directories often allow site owners to
submit their site for inclusion, and have editors review submissions for fitness.
RSS directories are similar to web directories, but contain collections of RSS feeds,
instead of links to web sites
A Web crawler is an Internet bot that systematically browses the World Wide Web, typically
for the purpose of Web indexing. A Web crawler may also be called a Web
spider, an ant, anautomatic indexer, or (in the FOAF software context) a Web scutter.
Web search engines and some other sites use Web crawling or spidering software to
update their web content or indexes of others sites' web content. Web crawlers can copy
all the pages they visit for later processing by a search engine that indexes the
downloaded pages so that users can search them much more quickly.
Crawlers can validate hyperlinks and HTML code. They can also be used for web
scraping (see also data-driven programming).
Googlebot is the search bot software used by Google, which collects documents from the web to build a searchable
index for the Google Searchengine.
If a webmaster wishes to restrict the information on their site available to a Googlebot, or another well-behaved spider,
they can do so with the appropriate directives in a robots.txt file, or by adding the meta tag <meta
name="Googlebot" content="nofollow" /> to the web page. Googlebot requests to Web servers are
identifiable by a user-agent string containing "Googlebot" and a host address containing "googlebot.com".

pages by harvesting all of the links on every page it finds. It then follows these links to other web pages. New web pages
must be linked to from other known pages on the web in order to be crawled and indexed or manually submitted by the
A problem which webmasters have often noted with the Googlebot is that it takes up an enormous amount of bandwidth.
This can cause websites to exceed their bandwidth limit and be taken down temporarily. This is especially troublesome
for mirror sites which host many gigabytes of data. Google provides "Webmaster Tools" that allow website owners to
throttle the crawl rate
