SEO - Search Engine Optimization

To implement SEO - Search Engine Optimization correctly, we must broke it down into 2 factors;

• on-page criteria: <title>,<meta-description>,<h1>,<h2>,...,<h6>,<b>,<i>, keyword proximity, keyword density and relevance, etc...
• off-page criteria: links (in pages within our website and pages of other websites) that point to our specific pages. The terms "Page Rank" is used to weight and evaluate off-page criteria. Special attention should be given to: anchor text, reference_tags, "title" attribute and "target_"

URL shortener - Convert long URL into short URL

When it comes to URL shorteners, fewer letters are always best. x.co is one of the shortest, publicly-accessible shortening applications around.
Go ahead to x.co, just copy and paste a long URL into the box, then use the neat little URL we provide in your Twitter or Facebook posts, comments, emails, blog posts - wherever you like.

Create thumbnails of jpeg, gif, png images using PHP script

?> 

Copy paste the above code in a new php file and save the file in the www directory ( or htdocs for xampp).
Place the original picture in the same www or htdocs directory and replace original_image.jpg with the name of the original picture.
Now go to browser and run
http://localhost/filename.php

A new file thumb.jpg should be created in the www or htdocs directory.
