Algorithms-The Foundation of Search Engine Optimization

Algorithms-The Foundation of Search Engine Optimization

In the ninth century Abu Abdullah Muhammad ibn Musa al-Khwarizmi, a Persian mathematician, introduced algebrac concepts and Arabic numerals while he was working in Baghdad. During the time Baghdad was the international center for scientific study. Abu Abdullah Muhammad ibn Musa al-Khwarizmi's process of performing arithmetic with Arabic numerals was called algorism. In the eighteenth century the name evolved into algorithm. Algorithms are a finite set of carefully defined instruction. Algorithms are procedures that are used for accomplishing some task which will end in a defined end-state. Algorithms are used in linguistics, computers, and mathematics.

Many people like to think of algorithms as steps in a well written recipe. Provided you follow each step of the recipe to the letter you will have an edible dinner. As long as you follow each step of the algorithm you will find the proper solution. Simple algorithms can be used to design complex algorithms.

Computers use algorithms as a way to process information. All computer programs are created with algorithms (or series of algorithms) that give the computer a list of instructions to follow. Computers usually read data from an input device when using an algorithm to process information. In order to be successful algorithms need to be carefully defined for a computer to read them. Program designers need to consider every possible scenario that could arise and set up a series of algorithms to resolve the problem. Designers have to be very careful not to change the order of the instructions; computers cannot cope with an algorithm that is in the wrong place. Flow of control refers to how the list of algorithms must start at the top and go all the way to the bottom, following every single step on the way.

Some terms that are used to describe algorithms include natural languages, flowcharts, psudocode, and programming languages. Natural expression algorithms are generally only seen in simple algorithms. Computers generally use programming languages that are intended for expressing algorithms.

There are different ways to classify algorithms. The first is by the specific type of algorithm. Types of algorithms include recursive and interative algorithms, deterministic and non-deterministic algorithms, and approximation algorithms. The second method used to classify algorithms is by their design methodology or their paradigm. Typical paradigm is are divide and conquer, the greedy method, linear programming, dynamic programming, search and enumeration, reduction, and probalictic and heuristic paradigms. Different fields of scientific study have different ways of classifying algorithms, classified to make their field as efficient as possible. Some different types of algorithms different scientific fields use include; search algorithms, merge algorithms, string algorithms, combinatorial algorithms, cryptography, sorting algorithms, numerical algorithms, graph algorithms, computational geometric algorithms, data compression algorithms, and parsing techniques.

Internet search engines use algorithms to aid in search engine optimization. Google's web crawler's use a link analysis algorithm to index and rank web pages. In an attempt to prevent webmasters from using underhanded schemes to influence search engine optimization, many internet search engines disclose as little about the algorithms they use in their optimization techniques.

SEO SECRETS 2011

Domain Authority
•
Domain authority is among the most important ranking factors in SEO
•
To rank in Google for a keyword your site needs to have online business or domain authority
•
Other real websites need to link to your website
•
You can't fake authority, but you can grow Google authority over time
•
The BBC for instance could rank in the top ten for anything - a new site cannot!

So Google calls it online business authority?
Basically, you have a ‘popular’ site a lot of other sites link to. Perhaps a site which has a lot of links from other online business authorities too. An OBA usually has a decent amount of traffic too. This is what Google calls it anyways.

SEO more usually talk about domain trust and domain authority based on the number, type and quality of incoming links to a site.
Examples of trusted, authority domains include Wikipedia, the W3C and Apple. How do you become an OBA? Through a killer brand or service, usually a lot of useful content on your site and through telling a lot of people about the excellent content on your site.
How do you take advantage of being an online business authority? Either you turn the site into a SEO Black Hole (only for the very biggest brands) or you pump out information – like all the time. On any subject.
Can you (on a smaller scale in certain niches) mimic an online business authority by recognising what OBAs do for Google, and why Google ranks these high in search result? These provide THE service, THE content, THE experience. This takes a lot of work and a lot of time to create, or even mimic.
In fact, as a SEO, I honestly think the content route is the only sustainable way for a most businesses to try to achieve OBA at least in their niche or locale. I concede a little ninja linkbuilding goes a long way to help, and y
