Search Engine Optimization (seo)

Search engine optimization (SEO)

Search engine optimization (SEO)is the process of affecting the visibility of a website or a web page in a web search engine‘s unpaid results often referred  as “natural”, “organic”, or “earned” results.

In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine’s users; these visitors can then be converted into customers. SEO may target different kinds of search, including image search, video search, academic search, news search, and industry-specific vertical search engines.
SEO (Search engine optimization ) is something different from “local search engine optimization” (LSEO) In this the main focus is on optimizing a business’ online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services. The former instead is more focused on national searches.
As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, HTML, and associated coding to increase its relevancy to specific keywords and to remove barriers from indexing activities of search engines.Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

Search Engine

A web search engine  is  a  software which is designed to search information on the World Wide Web (WWW).

The search results are often referred to as search engine results pages (S E R Ps). The information may be a mix of web pages, images, or other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

Search Engines play a very important role for every website to get its traffic audience. Each and every website owner wants to be in the top page of the search results. And This is done by S E O process. Now the question arises that what is S E O? lets have a brief look on this.

S E O -Search engine optimization is the process of affecting the visibility of a website or a web page in a web search engine’s unpaid results often referred to as ” natural “, ” organic”, or “earned” results. In general the earlier and more frequently a site appears in the search results list. The more visitors it will receive from the search engine’s users. Few of these visitors can then be converted into customers.

Methods

  • Getting indexed.

The leading search engines such as Google, Bing and Yahoo use crawlers to find pages for their algorithmic search results. Pages which are linked from other search engine indexed pages do not need to be submitted because they are found automatically.

  • Preventing crawling.

To avoid undesirable content in the search indexes, webmasters can instruct spiders not to crawl certain files or directories through the standard robots.txt file in the root directory of the domain

  • Increasing prominence.

Data Mining

Data mining is the computing process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.

Data mining involves six common classes of tasks:

  1. Anomaly detection

  2. Association rule learning

  3. Clustering

  4. Classification

  5. Regression

  6. Summarization

It can be referred as an interdisciplinary subfield of computer science. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use.
It also involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating.
The term is a misnomer, as the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction (mining) of data itself.
You can refer The book Data mining: Practical machine learning tools and techniques with Java (which covers machine learning materials) and was originally to be named just Practical machine learning, The term data mining was only added for marketing reasons.
The actual data mining task is the automatic or semi-automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records and dependencies which usually involves using database techniques such as spatial indices. These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis.

4GL- Fourth Generation Language

Fourth-Generation Programming Language (4GL) is a computer programming language is  visualised as a refinement of the style of languages classified as Third-Generation Programming Language (3GL).As each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details, making the language more programmer-friendly, powerful and versatile.

While the definition of 3GL has changed over time, it can be typified by operating more with large collections of information at once rather than just focusing on bits and bytes. Languages claimed to be 4GL may include support for database management, report generation, mathematical optimization, GUI development, or web development. Some researchers state that 4GLs are a subset of domain-specific languages.The concept of Fourth-Generation Programming Language was developed in late 1970s through the 1990s, overlapping most of the development of 3GLs. While 3GLs like C, C++, C#, Java, and JavaScript remain popular for a wide variety of uses, Fourth-Generation Programming Language as originally defined found narrower uses some of the most advanced 3GLs like Python, Ruby, and Perl combine some of 4GLs abilities within general-purpose of 3GL environment. Also, libraries with 4GL-like features have been developed as add-ons for most popular 3GLs. This make bit difficult to distinguis 4GLs and 3GLs.With respect to type here you can find some examples of Fourth-Generation Programming Language

What is PHP and what does PHP stand’s for?

, ,

PHP

Stand for: Hypertext Pre-processor (earlier called, Personal Home Page)
Well known category as a Server Sided language,
Mostly used in web design/web scripting industry
You may have heard of some other scripting languages like ASP, Python and Perl… and some more.PHP is also one of them .PHP is probably the most popular scripting language on the web to enhance web pages.
With PHP, we can do things like
·Create login pages
·Check details from a form
·Create forums, picture galleries, surveys…
And much more.




If you are a good observer you must have seen extensions as “.php” in the URL bar of your browser on several web pages. If you haven’t seen yet! Doesn’t matter I can list some name for you
· Wikipedia
· WordPress
· Flickr
· Facebook (though they have their own fork of P.H.P. called HHVM)
· Yahoo

Here authors have written some programming code to liven up the plain, old HTML (HyperText Markup Language), a standard markup language for creating web pages and web applications.PHP is known as a server-sided language. That’s the reason, P.H.P. doesn’t get executed on your computer, but on the computer you requested the page from. The results are then handed over to be displayed in the browser.
