SEO – (marketing term, closely related to position of your website in search result in Google, yahoo and other search engines)
Search engine optimization (SEO) is the process of improving the volume or quality of traffic to a web site from search engines via “natural” or un-paid (”organic” or “algorithmic”) search results as opposed to search engine marketing (SEM) which deals with paid inclusion. Typically, the earlier (or higher) a site appears in the search results list, the more visitors it will receive from the search engine. SEO may target different kinds of search, including image search, local search, and industry-specific vertical search engines. This gives a web site web presence.
As an Internet marketing strategy, SEO considers how search engines work and what people search for. Optimizing a website primarily involves editing its content and HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines.
The acronym “SEO” can also refer to “search engine optimizers,” a term adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house. Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Because effective SEO may require changes to the HTML source code of a site, SEO tactics may be incorporated into web site development and design. The term “search engine friendly” may be used to describe web site designs, menus, content management systems, images, videos, shopping carts, and other elements that have been optimized for the purpose of search engine exposure.
Another class of techniques, known as black hat SEO or Spamdexing, use methods such as link farms, keyword stuffing and article spinning that degrade both the relevance of search results and the user-experience of search engines. Search engines look for sites that employ these techniques in order to remove them from their indic.
Diffrence between SEO and SEM
Search Engine Optimization is term to describe all technuqies and processes of improving site positioning in organic search results (free).
Search Engine Marketing is term to desribe same as above but for “sponsored links” premium advertising (CPC type).
CPC – (marketing term for paid advertising, where charges depends of how many user will click and follow the ad, most popular tool using this idea is Google AdWords, sponsored links on the right hand side on search results, plus it is possible to put your ads on other websites related by subject or category.)
Pay per click (PPC) is an Internet advertising model used on websites, in which advertisers pay their host only when their ad is clicked. With search engines, advertisers typically bid on keyword phrases relevant to their target market. Content sites commonly charge a fixed price per click rather than use a bidding system.
Cost per click (CPC) is the amount of money an advertiser pays search engines and other Internet publishers for a single click on its advertisement that brings one visitor to its website.
In contrast to the generalized portal, which seeks to drive a high volume of traffic to one site, PPC implements so called affiliate model, that provides purchase opportunities wherever people may be surfing. It does this by offering financial incentives (in the form of a percentage of revenue) to affiliated partner sites. The affiliates provide purchase-point click-through to the merchant. It is a pay-for-performance model — if an affiliate does not generate sales, it represents no cost to the merchant. The affiliate model is inherently well-suited to the web, which explains its popularity. Variations include, banner exchange, pay-per-click, and revenue sharing programs.
Websites that utilize PPC ads will display an advertisement when a keyword query matches an advertiser’s keyword list, or when a content site displays relevant content. Such advertisements are called sponsored links or sponsored ads, and appear adjacent to or above organic results on search engine results pages, or anywhere a web developer chooses on a content site.
Although many PPC providers exist, Google AdWords, Yahoo! Search Marketing, and Microsoft adCenter are the three largest network operators, and all three operate under a bid-based model. Cost per click (CPC) varies depending on the search engine and the level of competition for a particular keyword.
The PPC advertising model is open to abuse through click fraud, although Google and others have implemented automated systems to guard against abusive clicks by competitors or corrupt web developers
SMO – (marketing term related to promoting product or portal on social portals like myspace, facebook, beebo, twitter etc)
Social media optimization (SMO) is a set of methods for generating publicity through social media, online communities and community websites. Methods of SMO include adding RSS feeds, social news buttons, blogging, and incorporating third-party community functionalities like images and videos. Social media optimization is related to search engine marketing, but differs in several ways, primarily the focus on driving traffic from sources other than search engines, though improved search ranking is also a benefit of successful SMO.
Social media optimization is in many ways connected as a technique to viral marketing where word of mouth is created not through friends or family but through the use of networking in social bookmarking, video and photo sharing websites. In a similar way the engagement with blogs achieves the same by sharing content through the use of RSS in the blogosphere and special blog search engines.
Social Media optimization is considered an integral part of an online reputation management (ORM) or Search Engine Reputation Management (SERM) strategy for organizations or individuals who care about their online presence.
Business Strategy Social Media Optimisation (SMO), is not limited to marketing and brand building. Increasingly smart businesses are integrating social media participation as part of their knowledge management strategy (ie. product/service development, recruiting, employee engagement and turnover, brand building, customer satisfaction and relations, business development and more).
LMS – (describing engines/software used to manage self learning portals)
A learning management system (LMS) is “a software application that automates the administration, documentation, tracking, and reporting of training events”.
LMSs range from systems for managing training/educational records to software for distributing courses over the Internet and offering features for online collaboration. In many instances, corporate training departments purchase LMSs to automate record-keeping as well as the registration of employees for classroom and online courses. Student self-service (e.g., self-registration on instructor-led training), training workflow (e.g., user notification, manager approval, wait-list management), the provision of on-line learning (e.g., Computer-Based Training, read & understand), on-line assessment, management of continuous professional education (CPE), collaborative learning (e.g., application sharing, discussion threads), and training resource management (e.g., instructors, facilities, equipment), are dimensions to Learning Management Systems.
Most LMSs are web-based to facilitate access to learning content and administration. LMSs are used by regulated industries (e.g. financial services and biopharma) for compliance training. It is also used by educational institutions to enhance and support classroom teaching and offering courses to a larger population of learners across the globe.
Some LMS providers include “performance management systems”, which encompass employee appraisals, competency management, skills-gap analysis, succession planning, and multi-rater assessments (i.e., 360 degree reviews).
For the commercial market, some Learning and Performance Management Systems include recruitment and reward functionality.
LMSs are based on a variety of development platforms, like Java/J2EE based architectures, Microsoft .NET, PHP, and usually employ the use of a database as back-end. Some systems are commercially developed and have non-free software licenses or restrict access to their source code, Other systems are free and open-source and frequently used. Other than the most simple, basic functionality, LMSs cater to, and focus on, different educational, administrative, and deployment requirements.
CMS – content management system or web content management system (WCMS)
Is a software system that provides website authoring, collaboration, and administration tools designed to allow users with little knowledge of web programming languages or markup languages to create and manage website content with relative ease. A robust WCMS provides the foundation for collaboration, offering users the ability to manage documents and output for multiple author editing and participation.
Most systems use a database to store page content, metadata, and other information assets that might be needed by the system. Content is frequently, but not universally, stored as XML to facilitate, reuse, and enable flexible presentation options.
Mostly we can see PHP/SQL based CMS systems. Where most popular today would be WordPress, Joomla, SocialEngine. But there are thousands of others like dating scripts, video sharing scripts (ClipShare,AVS,PHPMotion,ViMP,Vshare and many others).
TLD – Those are known domain extensions like .com .net .biz .gov, and all country extensions like .us .ie .pl .cn etc, but DNS system also allows to register domains like .bmw .kia .name .google .tpsa .you etc where root server will delegate it to the registrar, for Example IEDR.IE has bought rights for all .IE domains, their DNS server is controlling all other .IE domains and allows or not to propagate records from assigned name servers (domain name hosting company) . It is related to subject of Internet Governance and Alternative DNS ROOT servers, more on tld.webvague.com and igiic.com website.
A top-level domain or domain name (TLD) is the highest level of domain names in the root zone of the Domain Name System of the Internet. For all domains in lower levels, it is the last part of the domain name, that is, the label that follows the last dot of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is com, or COM, as domain names are not case-sensitive. Management of most top-level domains is delegated to responsible organizations by the Internet Corporation for Assigned Names and Numbers (ICANN), which operates the Internet Assigned Numbers Authority (IANA) and is in charge of maintaining the DNS root zone.
Originally, the top-level domain space was organized into three main groups, Countries, Categories, and Multiorganizations. An additional temporary group consisted only of the initial DNS domain, arpa, intended for transitional purposes toward the stabilization of the domain name system.
DNS (in simplest word ever: it translate
human language to computer language
name to IP
www.domain.com to 188.8.131.52
The Domain Name System (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most importantly, it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often used analogy to explain the Domain Name System is that it serves as the “phone book” for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.example.com translates to 184.108.40.206.
The Domain Name System makes it possible to assign domain names to groups of Internet users in a meaningful way, independent of each user’s physical location. Because of this, World-Wide Web (WWW) hyperlinks and Internet contact information can remain consistent and constant even if the current Internet routing arrangements change or the participant uses a mobile device. Internet domain names are easier to remember than IP addresses such as 220.127.116.11 (IPv4) or 2001:db8:1f70::999:de8:7648:6e8 (IPv6). People take advantage of this when they recite meaningful URLs and e-mail addresses without having to know how the machine will actually locate them.
The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. Authoritative name servers are assigned to be responsible for their particular domains, and in turn can assign other authoritative name servers for their sub-domains. This mechanism has made the DNS distributed, fault tolerant, and helped avoid the need for a single central register to be continually consulted and updated.
In general, the Domain Name System also stores other types of information, such as the list of mail servers that accept email for a given Internet domain. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet.
Other identifiers such as RFID tags, UPC codes, International characters in email addresses and host names, and a variety of other identifiers could all potentially utilize DNS
PHP – powerful and most common scripting language
PHP, or PHP: Hypertext Preprocessor, is a widely used, general-purpose scripting language that was originally designed for web development, to produce dynamic web pages. It can be embedded into HTML and generally runs on a web server, which needs to be configured to process PHP code and create web page content from it. It can be deployed on most web servers and on almost every operating system and platform free of charge. PHP is installed on over 20 million websites and 1 million web servers.
PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development ever since. The main implementation of PHP is now produced by The PHP Group and serves as the de facto standard for PHP as there is no formal specification. PHP is free software released under the PHP License, which is incompatible with the GNU General Public License (GPL) because of restrictions on the use of the term PHP.
PHP has evolved to include a command line interface capability and can also be used in standalone graphical applications.
SQL – database, together with PHP and CSS it is background 99% of internet websites and portals.
SQL (Structured Query Language)  is a database computer language designed for managing data in relational database management systems (RDBMS). Its scope includes data query and update, schema creation and modification, and data access control. SQL was one of the first languages for Edgar F. Codd’s relational model in his influential 1970 paper, “A Relational Model of Data for Large Shared Data Banks” and became the most widely used language for relational databases.
CSS – as name says, Cascading Style Sheets. Next step in the evolution of HTML. Those times used as main template for HTML website.
All engines like Joomla, WordPress, Drupal, Social Engine etc are using combination of PHP commands calling to SQL dba and cascading of CSS, so it is crutial to know all 3, well it is not that difficult as CSS can be compared to HTML which is the simplest to learn.
Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation semantics (that is, the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can be applied to any kind of XML document, including SVG and XUL.
CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the colors, fonts, and layout. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design). CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. While the author of a document typically links that document to a CSS style sheet, readers can use a different style sheet, perhaps one on their own computer, to override the one the author has specified.
CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element. In this so-called cascade, priorities or weights are calculated and assigned to rules, so that the results are predictable.
The CSS specifications are maintained by the World Wide Web Consortium (W3C). Internet media type (MIME type) text/css is registered for use with CSS by RFC 2318 (March 1998).
FLASH – for best animation and fancy websites. (best for multimedia presentations, irreplaceable for web cam support, not so good for SEO, especially if not using advanced FLASH design integrated with eternal XML source. So what usualy is used it the mix of CSS and FLASH for simple websites, and PHP+SQL+CSS+some fancy FLASH effects and banners for more advanced websites)
Adobe Flash (previously known as Macromedia Flash) is a multimedia platform originally acquired by Macromedia and currently developed and distributed by Adobe Systems. Since its introduction in 1996, Flash has become a popular method for adding animation and interactivity to web pages. Flash is commonly used to create animation, advertisements, and various web page Flash components, to integrate video into web pages, and more recently, to develop rich Internet applications.
Flash can manipulate vector and raster graphics, and supports bidirectional streaming of audio and video. It contains a scripting language called ActionScript. Several software products, systems, and devices are able to create or display Flash content, including Adobe Flash Player, which is available free for most common web browsers, some mobile phones and for other electronic devices (using Flash Lite). The Adobe Flash Professional multimedia authoring program is used to create content for the Adobe Engagement Platform, such as web applications, games and movies, and content for mobile phones and other embedded devices.
Files in the SWF format, traditionally called “ShockWave Flash” movies, “Flash movies” or “Flash games”, usually have a .swf file extension and may be an object of a web page, strictly “played” in a standalone Flash Player, or incorporated into a Projector, a self-executing Flash movie (with the .exe extension in Microsoft Windows or .hqx for Macintosh). Flash Video files[spec 1] have a .flv file extension and are either used from within .swf files or played through a flv-aware player, such as VLC, or QuickTime and Windows Media Player with external codecs added.
