SEO Analyzer v 1.2 – Adding support for Bing along with Google and Yahoo

Abhinav Singh — Thu, 11 Jun 2009 11:51:12 +0000

On May 28, 2009 Microsoft announced Bing which has now replaced Live search. And within 2 week of it’s release, Bing seems to have leapfrog Yahoo search in U.S.

With Bing coming up as a strong contender to Google and Yahoo search engines, I have added support for Bing in SEO Analyzer v 1.2. This will enable you to analyze a site’s ranking for a particular keyword on Bing search engine, along with Yahoo and Google search engines.

SEO Analyzer Future Roadmap:

Saving reports on spreadsheets
Comparing two sites for a list of keywords
Keyword density extraction tool

Happy SEO Analysis!

Getting Google Page Rank using Javascript – For Adobe AIR Apps

Abhinav Singh — Fri, 17 Apr 2009 18:56:52 +0000

Last week while working on SEO Analyzer v 1.1 desktop application, I faced a challenge of getting google page rank for a particular site using javascript. I am not sure if someone has already done this before, but I thought of sharing this javascript code for all adobe air and web developers out there.

googlepagerank.js

var googlepagerank = {
	hexdec: function(hex_string) {
	    hex_string = (hex_string+'').replace(/[^a-f0-9]/gi, '');
	    return parseInt(hex_string, 16);
	},
	count: function( mixed_var, mode ) {
	    var key, cnt = 0;
	    if( mode == 'COUNT_RECURSIVE' ) mode = 1;
	    if( mode != 1 ) mode = 0;
	    for (key in mixed_var){
	        cnt++;
	        if( mode==1 && mixed_var[key] && (mixed_var[key].constructor === Array || mixed_var[key].constructor === Object) ){
	            cnt += count(mixed_var[key], 1);
	        }
	    }
	    return cnt;
	},
	sizeof: function( mixed_var, mode ) {
	    return googlepagerank.count( mixed_var, mode );
	},
	ord: function(string) {
	    return (string+'').charCodeAt(0);
	},
	strlen: function(string) {
	    var str = string+'';
	    var i = 0, chr = '', lgth = 0;
	    var getWholeChar = function (str, i) {
	        var code = str.charCodeAt(i);
	        var next = '', prev = '';
	        if (0xD800 <= code && code <= 0xDBFF) {
	            if (str.length <= (i+1))  {
	                throw 'High surrogate without following low surrogate';
	            }
	            next = str.charCodeAt(i+1);
	            if (0xDC00 > next || next > 0xDFFF) {
	                throw 'High surrogate without following low surrogate';
	            }
	            return str[i]+str[i+1];
	        } else if (0xDC00 <= code && code <= 0xDFFF) {
	            if (i === 0) {
	                throw 'Low surrogate without preceding high surrogate';
	            }
	            prev = str.charCodeAt(i-1);
	            if (0xD800 > prev || prev > 0xDBFF) {
	                throw 'Low surrogate without preceding high surrogate';
	            }
	            return false;
	        }
	        return str[i];
	    };
	    for (i=0, lgth=0; i < str.length; i++) {
	        if ((chr = getWholeChar(str, i)) === false) {
	            continue;
	        }
	        lgth++;
	    }
	    return lgth;

How to use script in an adobe air application

How to use script in an web applications
This script cannot be used directly for web applications, mainly because of cross domain XHR limitations. However the script can be modified to use with proxy script provided at developer.yahoo.com

Please Note: Getting google page rankings is/might be illegal as per google's policy. If you use this script from webservers, possibilities are google might block your server IP Address. However with adobe air applications (desktop apps), risk is minimized.
