what is rss feed?
A web feed (or news feed) is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by an aggregator. A web feed is also sometimes referred to as a syndicated feed. A typical scenario of web feed use is: a content provider publishes a feed link on their site which end users can register with an aggregator program (also called a feed reader or a news reader) running on their own machines; doing this is usually as simple as dragging the link from the web browser to the aggregator. When instructed Johnathan Abram Camo Jersey , the aggregator asks all the servers in its feed list if they have new content; if so, the aggregator either makes a note of the new content or downloads it. Aggregators can be scheduled to check for new content periodically. Web feeds are an example of pull technology, although they may appear to push content to the user. The kinds of content delivered by a web feed are typically HTML (webpage content) or links to webpages and other kinds of digital media. Often when websites provide web feeds to notify users of content updates, they only include summaries in the web feed rather than the full content itself. Web feeds are operated by many news websites Josh Jacobs Camo Jersey , weblogs, schools, and podcasters.
what is links Directory?
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.[1] The categorization is usually based on the whole web site rather than one page or a set of keywords Clelin Ferrell Camo Jersey , and sites are often limited to inclusion in only a few categories. Web directories often allow site owners to directly 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.

Most of the directories are very general in scope and list websites across a wide range of categories Antonio Brown Camo Jersey , regions and languages. But there are also some niche directories which focus on restricted regions, single languages, or specialist sectors. One type of niche directory with a large number of sites in existence, is the shopping directory for example. Shopping directories specialize in the listing of retail e-commerce sites. Examples of well known Derek Carr Camo Jersey , general, web directories are Yahoo! Directory and the Open Directory Project (ODP). ODP is significant due to its extensive categorization and large number of listings and its free availability for use by other directories and search engines.[2] However, a debate over the quality of directories and databases still continues, as search engines use ODP's content without real integration Bo Jackson Camo Jersey , and some experiment using clustering. There have been many attempts to make directory development easier, such as using automated submission of related links by script, or any number of available PHP portals and programs. Recently, social software techniques have spawned new efforts of categorization Hunter Renfrow Rush Jersey , with Amazon adding tagging to their product pages. Directories have various features in listing, often depend upon the price paid for inclusion: Free submission ? there is no charge for the review and listing of the site Reciprocal link ? a link back to the directory must be added somewhere on the submitted site in order to get listed in the directory Paid submission ? a one-time or recurring fee is charged for reviewinglisting the submitted link No follow ? there is a rel="nofollow" attribute associated with the link, meaning search engines will give no weight to the link. Featured listing ? the link is given a premium position in a category (or multiple categories) or other sections of the directory, such as the homepage. Sometimes called sponsored listing. Bid for position ? where sites are ordered based on bids Affiliate links ? where the directory earns commission for referred customers from the listed websites
