SEO explanation

 SEO Explanation

SEO means  “search engine optimization.”  it is the process of improving your site to increase its visibility for relevant searches. It is a digital marketing strategy that focuses on your website’s presence in search results on search engines like Google.

How SEO works

Search engines such as Google and Bing use bots to crawl pages on the web, going from site to site, collecting information about those pages and putting them in an index. Next, algorithms analyze pages in the index, taking into account hundreds of ranking factors or signals, to determine the order pages should appear in the search results for a given query.

Search engines have spiders — not the creepy kind, but the automated robot kind.

These spiders collect all kinds of information about your website and the pages that make up your site. This allows them to easily determine when to serve a searcher a page on your site. They collect things like page speed, title tags, social signals, internal linking, backlinks, and so on.

Ranking factors used by Google in their algorithm, there are a lot of things to consider, and actions that can be taken to try to optimize a website. There are both on-page and off-page ranking factors that determine how well your site is optimized, and therefore how well it ranks.

Q1. Create a Node.js file that will convert the output "Hello World!" into upper-case letters.

var http = require('http');

var uc = require('upper-case');

http.createServer(function (req, res) {

  res.writeHead(200, {'Content-Type': 'text/html'});

  res.write(uc.upperCase("Hello World!"));

  res.end();

}).listen(8080);

Save the code above in a file called "d_uppercase.js", and initiate the file:

First Install module 'upper-case' using npm

C:\Users\Your Name>npm install upper-case

Initiate d_uppercase:

C:\Users\Your Name>node d_uppercase.js

If you have followed the same steps on your computer, you will see the same result as the example: http://localhost:8080
