Day 4 :
Today i well grounded about what is a Search Engine Optimisation (SEO), how do Search Engine works and I learned the role of Key Words in Search Engine Optimisation.
SEARCH ENGINE OPTIMISATION :
Search Engine Optimization is the process of improving the visibility of a website on organic ("natural" or un-paid) search engine result pages, by incorporating search engine friendly elements into a website. A successful search engine optimization campaign will have, as part of the improvements, carefully select, relevant, keywords which the on-page optimization will be designed to make prominent for search engine algorithms. Search engine optimization is broken down into two basic areas: on-page, and off-page optimization. On-page optimization refers to website elements which comprise a web page, such as HTML code, textual content, and images. Off-page optimization refers, predominantly, to backlinks (links pointing to the site which is being optimized, from other relevant websites).
How do search engine works?
A search engine works in the process as follows,
Algorithms :
A search algorithm is defined as a math formula that takes a problem as input and returns a solution to the problem, usually after evaluating a number of possible solutions. A search engine algorithm uses keywords as the input problem, and returns relevant search results as the solution, matching these keywords to the results stored in its database. These keywords are determined by search engine spiders that analyze web page content and keyword relevancy based on a math formula that will vary from one search engine to the next.
Crawling :
Crawling is where it all begins – the acquisition of data about a website. This involves scanning the site and getting a complete list of everything on there – the page title, images, keywords it contains, and any other pages it links to – at a bare minimum. Modern crawlers may cache a copy of the whole page, as well as look for some additional information such as the page layout, where the advertising units are, where the links are on the page
Indexing :

Indexing :
You’d be forgiven for thinking this is an easy step – indexing is the process of taking all of that data you have from a crawl, and placing it in a big database. Imagine trying to a make a list of all the books you own, their author and the number of pages. Going through each book is the crawl and writing the list is the index. But now imagine it’s not just a room full of books, but every library in the world. That’s pretty much a small-scale version of what Google does.
Ranking :
The last step is what you see – you type in a search query, and the search engine attempts to display the most relevant documents it finds that match your query. This is the most complicated step, but also the most relevant to you or I, as web developers and users.
Key Words
Your SEO keywords are the key words and phrases in your web content that make it possible for people to find your site via search engines. A website that is well optimized for search engines "speaks the same language" as its potential visitor base with keywords for SEO that help connect searchers to your site. Keywords are one of the main elements of SEO bascis.
In other words, you need to know how people are looking for the products, services or information that you offer, in order to make it easy for them to find you—otherwise, they'll land on one of the many other pages in the Google results. Implementing keyword SEO will help your site rank above your competitors.
The process of implementing key words in a Search Engine Optimization is,
- Keyword Research
- How to judge the value of key word
- Understanding the Long Tail of Keyword Demand
- Keyword Difficulty
KEYWORD RESEARCH
It all begins with words typed into a search box.Keyword research is one of the most important, valuable, and high return activities in the search marketing field.By researching your market's keyword demand, you can not only learn which terms and phrases to target with SEO, but also learn more about your customers as a whole.It's not always about getting visitors to your site, but about getting right time of visitors.
How much is a keyword worth to your website? If you own an online shoe store, do you make more sales from visitors searching for "brown shoes" or "black boots"? The keywords visitors type into search engines are often available to webmasters, and key word research tools allow us to find this information. However, those tools cannot show us directly how valuable it is to receive traffic from those searches. To understand the value of a keyword, we need to understand our own websites, make some hypotheses, test, and repeat—the classic web marketing formula.
UNDERSTANDING THE LONG TAIL OF KEYWORD DEMAND
Going back to our online shoe store example, it would be great to rank #1 for the keyword "shoes" ... or would it? It's wonderful to deal with keywords that have 5,000 searches a day, or even 500 searches a day, but in reality, these popular search terms actually make up less than 30% of the searches performed on the web.
The remaining 70% lie in what's called the "long tail" of search. The long tail contains hundreds of millions of unique searches that might be conducted a few times in any given day, but, when taken together, comprise the majority of the world's search volume.
KEYWORD DIFFICULTY
In order to know which keywords to target, it's essential to not only understand the demand for a given term or phrase, but also the work required to achieve high rankings. If big brands take the top 10 results and you're just starting out on the web, the uphill battle for rankings can take years of effort. This is why it's essential to understand keyword difficulty.
