Sitemap Protocol
The Sitemaps protocol allows a webmaster to inform search engines about URLs on a website that are available for crawling. A Sitemap is an XML file that lists the URLs for a site. It allows webmasters to include additional information about each URL: when it was last updated, how often it changes, and how important it is in relation to other URLs of the site. This allows search engines to crawl the site more efficiently and to find URLs that may be isolated from the rest of the site's content. The Sitemaps protocol is a URL inclusion protocol and complements robots.txt, a URL exclusion protocol. History Google first introduced Sitemaps 0.84 in June 2005 so web developers could publish lists of links from across their sites. Google, Yahoo! and Microsoft announced joint support for the Sitemaps protocol in November 2006. The schema version was changed to "Sitemap 0.90", but no other changes were made. In April 2007, Ask.com and IBM announced support for Sitemaps. Also, Google ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robots Exclusion Standard
The robots exclusion standard, also known as the robots exclusion protocol or simply robots.txt, is a standard used by websites to indicate to visiting web crawlers and other web robots which portions of the site they are allowed to visit. This relies on voluntary compliance. Not all robots comply with the standard; email harvesters, spambots, malware and robots that scan for security vulnerabilities may even start with the portions of the website where they have been told to stay out. The "robots.txt" file can be used in conjunction with sitemaps, another robot inclusion standard for websites. History The standard was proposed by Martijn Koster, when working for Nexor in February 1994 on the ''www-talk'' mailing list, the main communication channel for WWW-related activities at the time. Charles Stross claims to have provoked Koster to suggest robots.txt, after he wrote a badly-behaved web crawler that inadvertently caused a denial-of-service attack on Koster's server. I ...

Yahoo! Site Explorer
Yahoo! Site Explorer (YSE) was a Yahoo! service which allowed users to view information on websites in Yahoo!'s search index. The service was closed on November 21, 2011 and merged with Bing Webmaster Tools, a tool similar to Google Search Console (previously Google Webmaster Tools). In particular, it was useful for finding information on backlinks pointing to a given webpage or domain because YSE offered full, timely backlink reports for any site. After merging with Bing Webmaster Tools, the service only offers full backlink reports to sites owned by the webmaster. Reports for sites not owned by the webmaster are limited to 1,000 links. Webmasters who added a special authentication code to their websites were also allowed to: * See extra information on their sites * Submit Sitemaps The Sitemaps protocol allows a webmaster to inform search engines about URLs on a website that are available for crawling.

Resources Of A Resource
Resources of a Resource (ROR) is an XML format for describing the content of an internet resource or website in a generic fashion so this content can be better understood by search engines, spiders, web applications, etc. The ROR format provides several pre-defined terms for describing objects like sitemaps, products, events, reviews, jobs, classifieds, etc. The format can be extended with custom terms.RORweb.comis the official website of ROR; the ROR format was created by AddMe.com as a way to help search engines better understand content and meaning. Similar concepts, like Google Sitemaps and Google Base, have also been developed since the introduction of the ROR format. ROR objects are placed in an ROR feed called ror.xml. This file is typically located in the root directory of the resource or website it describes. When a search engine like Google or Yahoo Yahoo!

It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...

Biositemap
A Biositemap is a way for a biomedical research institution of organisation to show how biological information is distributed throughout their Information Technology systems and networks. This information may be shared with other organisations and researchers. The Biositemap enables web browsers, crawlers and robots to easily access and process the information to use in other systems, media and computational formats. Biositemaps protocols provide clues for the Biositemap web harvesters, allowing them to find resources and content across the whole interlink of the Biositemap system. This means that human or machine users can access any relevant information on any topic across all organisations throughout the Biositemap system and bring it to their own systems for assimilation or analysis. File framework The information is normally stored in a biositemap.rdf or biositemap.xml file which contains lists of information about the data, software, tools material and services provided or ...

Hreflang
The rel="alternate" hreflang="x" link attribute is a HTML meta element described in RFC 8288. Hreflang specifies the language and optional geographic restrictions for a document. Hreflang is interpreted by search engines and can be used by webmasters to clarify the lingual and geographical targeting of a Website. Purpose Many websites are targeted at audience with different languages and localized for different countries. This can cause a lot of duplicate content or near duplicate content, as well as targeting issues with users from search engines. Search engines use hreflang to understand the lingual and geographical targeting of websites and use the information to show the right URL in search results, depending on user language and region preference. There are 3 basic scenarios that can be covered with hreflang: * Same country, different languages * Different countries, different languages * Different countries, same language Hreflang attribute help your website deliver m ...

Gzip
gzip is a file format and a software application used for file compression and decompression. The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from where the "g" of gzip is derived). Version 0.1 was first publicly released on 31 October 1992, and version 1.0 followed in February 1993. The decompression of the ''gzip'' format can be implemented as a streaming algorithm, an important feature for Web protocols, data interchange and ETL (in standard pipes) applications. File format gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of compress and other popular archivers. "gzip" is often also used to refer to the gzip file format, which is: * a 10-byte header, contai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
