Clean Room Implementation of Google Page Rank AlgorithmAugust 17th, 2006 Finally a clean-room implementation of Google's Page Rank Algorithm in Java, reverse-engineered from their numerous commentary on Page Rank (or is it Pigeon Rank?). public static int getPageRank(url) {
// start off with a random low PR
int pageRank = rand.getInt(0, 3);
if ( isHostedOn('google.com', url) ) {
pageRank++;
} else if ( isHostedOn('microsoft.com', url) ) {
pageRank--;
}
// Support valid pages
if (isValidPage(url) ) {
pageRank += 1;
}
tag_value['b'] = 1;
tag_value['h2'] = 2;
tag_value['h1'] = 3;
tag_value['strong'] = -1; // W3C sux!
pageRank = calculateTagsPR(tag_value, pagerank);
// Sergey said good news sites have
// lots of nested tables
tablesOnPage = getTagCount('table');
if (tablesOnPage >= 50) {
pageRank += 2;
}
if (pageRank >= 5) {
pageRank = 4; // helps selling AdWords
}
if (linksFrom('mattcutts.com', url) >= 4) {
// I link to "clean" sites only
// ? Matt, Feb 2006
pagerank += 2;
}
pagerank += countBacklinks(url) / 10000;
blacklist1 = getList('c:\chinese-government-censored.txt');
blacklist2 = getList('c:\larry-page-hatelist.txt');
if ( inArray(blacklist1, url) || inArray(blacklist2, url) ) {
pageRank = 0;
}
d = dashesInUrl(url);
pageRank = (d >= 3) ? pageRank -1 : pageRank + 1;
if (inString(url, "how to build a bomb")) {
// added on request.

Is Google punishing weblogs aka blogs?April 13th, 2005 Nowadays I have noticed that Google apparently confers pagerank only to the front page of the blog. All other pages appear to have a rank of zero! I have noticed it across a wide spectrum of blogs, even blogs with very high pageranks.

Google Proxy Hacking - How Your Page Rank Can Be Stolen & Pages Removed from SERPFebruary 23rd, 2008 I recently came across an instance of Google Proxy hacking with one of my clients, which removed his index page and other pages from SERP (Search Engine Ranking & Positioning) and he lost the page ranks (went down to zero). We were asked to protect his site against Google Proxy hacking, a really dangerous technique which can not only cause you to loose page rank but also remove your pages from SERP, all because Google cannot properly identify original pages from duplicates.

I recently received one of those “published updates” from TLA and have contacted their support department to close my TLA account because of it. Unfortunately, no one has responded for three days now.
The first point simply shows the typical business sense of any advertiser. It basically says, “We don’t care about your site. We just want people to click on our ads.” While I normally wouldn’t be bothered by this, TLA was founded on the principle that advertisements should be unobtrusive, but this recommendation seems to go against that principle. Scott Yang recently received a request to “change the ‘Sponsored Links’ text to something like ‘Friends’ or something along those lines,” which further betrays their company’s original ideals and crosses a line by requesting that the publisher intentionally deceive his audience. These links don’t represent friends, they represent sponsors.
The last point is very puzzling. TLA’s referral system allows you to create “Advertise Here” (and similar) links which link back to your listing at TLA, and even though this option still exists, they are very to-the-point about removing such links. Furthermore, these links help to direct interested parties towards TLA and eventually result in more revenue for both the publisher and TLA. This request does not seem practical, unless they are planning to close TLA, or are desperate to decrease ad sales.
The online advertising industry is slowly becoming confusing and obtrusive again. In the long-run, my blog doesn’t need commercial sponsors to stay alive. I left AdSense two months ago, and now it’s time to leave TLA before things get any worse.

Angusman, thanks for the couple of posts about TLA. I had just been looking at them as a way to boost the PR of my blog. However, I do not want to venture into anything remotely grey or black, in terms of gaining traffic and an audience.
It is sad that advertisers expect bloggers to sell out, just like any other company. But that is ignoring the basis of blogging: honesty from your fellow person.
Thanks again!

After not receiving a response for about a week (see first comment), I decided to re-send my request and got a reply in only 40 minutes (go figure). Unfortunately, since closing your account now constitutes a “breach of contract”, I will not be compensated for the past month of ad display. You dodged the bullet on that one, Angsuman!

Nice info. Thanx for sharing and giving the good tips. I just started my blog, and planning to put Google ads when I have more visitor. Perhaps you could give me a support. Thanx a bunch

I just got into a bit of a tiff with TLA myself about this… I would prefer not to have to resort to TLA and would like more obvious forms of sponsorship, but I make very clear through my use of these google-identifiable disclaimers just what is going on.

You can cancel - just call the publisher support line and tell them to cancel it. They did it for a friend of mine.

No matter what somebody will do to avoid the google penaly, google will always find a way to penalise all these sites. Sooner or later.

I was looking for any tips about TLA and I found yours. I guess I’ll think twice before putting sponsored ads on my blog, thanks for sharing

balls with the google, they don’t want other advertising company to come up, they just want to rule
the web, bullshit, this is what monopoly game play, it
is bloggers or publisher and other advertiser should really ignore this page rank thing, instead they should look at the traffic values, and judge a site or
a blog by its values, why page rank, points to ponder, does PR pays your hosting bills? damn it, adsense hardly pays, and now they are trying to dump paid links company, bullshit, whats wrong with the google?
